Health & Welfare Bulletin No. 37 : Schmallenberg Virus
SCHMALLENBERG VIRUS ALERT
What appears to be a new virus has been discovered in the North Rhein Westphalia district of the west of Germany, and in Holland. It has been named Schmallenberg virus after the small town where it was first discovered.
Outbreaks of disease were originally seen in cattle last August. Clinical signs exhibited by affected cattle included fever, reduced milk yields, inappetance, weight loss and diarrhoea: since November, there have been reports in sheep (and, to a lesser extent, cattle and goats) of abortion, still-births and congenital abnormalities. These congenital abnormalities have included limb contractures, brain abnormalities and twisted neck: no clinical signs were reported affecting dams of these offspring. No cases of the disease have been reported in camelids, and it is unknown whether or not they can be affected.
Research on the virus is still in its early stages but the virus is thought to belong to the genus Orthobunyavirus: this group includes the Akabane virus and although antibodies to Akabane virus have been found in camels, it is not known whether or not it causes disease (Al Busaidy et al, 1988; Davies & Jessett, 1985). Viruses of this genus are spread by arthropod vectors – midges and mosquitoes. No information is available for viruses of this group affecting South American Camelids. Therefore it is unknown whether or not they are likely to be affected with clinical disease. It is certainly possible that they are susceptible.
It has to be stressed that this virus has not yet been detected in the UK. There is potential for it to come to the UK via windborne spread of athropod vectors that carry the virus (as occurred with Bluetongue), or potentially via imported animals. Disease surveillance is ongoing and keepers of livestock are being urged to monitor for signs of disease and consult with their vet in case of concern.
AHVLA have asked that if any ruminants imported from anywhere in Europe during 2011 abort, or have stillborn or deformed offspring, please report the matter to your local AHVLA laboratory, or SAC laboratory if in Scotland. In England, ruminant samples will be taken for testing free of charge, although as tests for the disease are still under development, results will not be known immediately. Be sure to check with your local office whether charges will apply for camelids before submitting any crias for testing. In Scotland, the normal SAC charges will apply.
Similarly, if there are ANY aborted foetuses or stillborn animals which match the pattern of deformities described, please discuss them with AHVLA to see if samples should be taken for investigation, in particular if born to dams who had what would have been an undiagnosable fever in the late summer or early autumn. Again, to avoid embarrassment, discuss what charges might be made, if any, when discussing things with AHVLA.

Since this virus has only just been identified and the epidemiology and pathogenesis of the disease is far from known, this situation is evolving and further information will be forthcoming as more research is done. AHVLA will keep updating the information available on their website as more becomes known. [http://www.defra.gov.uk/ahvla/news/]. It will be particularly important for us in the UK later in the year when we shall see if infected midges have crossed the North Sea, and this will depend on weather patterns during the summer. However it is POSSIBLE that infected midges could have crossed to England during 2011 although there were only a few days where this was considered to have been a possibility. As yet there is no evidence of this having happened, but please be on the lookout. This is a new disease, and hopefully we will develop a far better understanding of the epidemiological risk to the UK over the next 12 months.
Please do not panic. This is a very new virus and as previously stated, there have been no cases notified in Camelids but it is better to be aware of the unfolding situation.
I would like to acknowledge the following vets for assisting in producing this report:

Please report any abnormalities in your herd to your vet.
Health & Welfare Bulletin No. 36 : Winter Catch Up
Remember if we have a really cold spell, below freezing for a number of days, always break any ice on the water and look out for signs of your camelids not drinking. Some camelids will not drink freezing water. In these cases (very few) add a little hot water to the bucket so the water is cold but not icy and check the animal drinks some. Hay is very dry and therefore our animals need more water in the winter than in the summer when they get a lot of their water from the grass.
I expect many of you will be aware of the proposed badger cull in England. Due to this contentious decision by the Government and the high cost of policing, it will not take place until after the Para-Olympics, i.e. back end of the year.
In the farming press and various newspapers, it has been reported that a number of Veterinary Laboratory Agencies (VLA) are to close. There will be only six remaining in operation: 1) Shrewsbury, 2) Penrith, 3) Sutton Bonnington 4) Bury St.Edmonds, 5) Newcastle, 6) Star Cross.
BUT this only refers to the laboratories; the actual VLA where you take animals for post mortem will remain open for the time being. If the VLA find anything they are not happy about they will send samples to a laboratory that has stayed open.
If you have an animal die unexpectedly or in suspicious circumstances, please get your vet to carry out a post mortem or ask your vet to make arrangements for it to have a post mortem at your local VLA.
As time goes by, we are finding more and more camelids need to be re-homed. Some of these cases are genuine but we are finding some people have taken on animals and then suddenly decided they don’t want them anymore!
Camelids can live for over 20 years. Have you made provision for your camelids to be looked after and cared for should a disaster befall you? This may sound hard, but please think about what would happen to your lovely animals if you were no longer around to look after them.
Make provision in your will. Do you have a reliable family member who would take them on? Ask another member of BLS (providing them with the finance) to care for your animals.
The BLS Board is considering the setting up of a fund and more details will be in the spring edition of Llama Link. You could run coffee mornings, bring and buy sales or just give money. This would be ‘ring fenced’ for the welfare of beautiful animals that need help.
We are also in the market for a philanthropic person who would like to donate a farm to the whole of the camelid industry as a refuge/rescue centre. Put your thinking caps on!!

Health & Welfare Bulletin No.35 : Autumn Catch Up
If you have hard feed left over from last winter, check it for signs of mould. If mouldy, throw it away as it could harbor bacteria. (My birds love it but if you feed the birds, do it out of the reach of vermin or you are asking for trouble).
Now is a good time to give the annual vaccination to your animals. They should all have had a good summer with nice grass to get them ready for the winter ahead. (Hopefully we will not have as bad a winter as the last two winters have been.) Worming should also be considered.
Due to the weather conditions, Horse Chestnut trees and Oak trees have been producing a huge number of conkers and acorns. Both of these, in quantity, are poisonous to Camelids. It would be a good idea to collect as many of these seeds as possible if you have them in your fields and remove them. Usually camelids do not bother eating them BUT if the grass has now been eaten down or the animal are a bit stressed, they tend to turn to conkers and acorns. Weanlings are a high risk in this respect as they are stressed about ‘Mum’ not being around anymore.
Remember if we have a really cold spell, below freezing for a number of days, always break any ice on the water and look out for signs of your camelids not drinking. Some camelids will not drink freezing water. In these cases (very few) add a little hot water to the bucket so the water is cold but not icy and check the animal drinks some. Hay is very dry and therefore our animals need more water in the winter than in the summer when they get a lot of their water from the grass.
Don’t forget, you all have a Regional Representatives to help with any problems. You will find their names and details on the back of the Llama Link magazine. Please do not feel embarrassed contacting them – that is what they are there for.

Health & Welfare Bulletin No.33 : Wasps and Bees
*** Caution - Wasps and Bees ***
There have been reports of some very unfortunate incidents involving large animals and stinging insects. The animals have been stung badly and have required veterinary treatment.
All owners are advised to check round the hedges of their paddocks on a fine day. If you notice an unusual amount of insect activity, check whether there is a wasps nest or a bee swarm established in the hedge. If there is and any of your animals inadvertently go too close or disturb the nest, the occupants will do what comes naturally which is to sting and chase the 'predator' away. When the insect attacks (or defends its nest depending on your point of view), it burrows down through the coat until it reaches the skin. When they sting, both wasps and bees emit a pheromone which attracts their nest mates to come and help. If the predator does not move away quickly, more insects will sting.
Neither wasps nor bees will sting unless they perceive they are in danger. There are no 'killer bees' in this country and, even if there were, they would still not actively seek out a subject to attack, contrary to the popular depiction in the movies!
If you find a nest, determine whether it is wasps or bees. Wasps have distinct black and yellow stripes. They form their nest out of chewed wood pulp. It is usually roughly spherical and will be hanging from a branch in the hedge. Bees have more muted colours, ranging from completely dark to those with yellow segments on their abdomens. They build parallel, vertical combs from beeswax which are protected by a cluster of bees.
You will need to get a pest controller to deal with a wasps nest. If you can get in touch with the local beekeeping association, one of its members may well be prepared to come and collect a swarm.
If possible, move your animals to another paddock until the nest has been removed. If this is not possible, fence it off from their attentions.
Health & Welfare Bulletin No.32 : BTV
BTV FREEDOM NEWS RELEASE
The key points are:
Vaccination will be prohibited from July 5.
Exports: There will be no bluetongue restrictions on animals moving out of GB to other EU Member States from July 5. This means that vaccination or any other ‘Annex III conditions’ will no longer be required.
Imports: There is no change for imports into GB from countries/areas that are under bluetongue restrictions. All animals will continue to meet full ‘Annex III conditions’ unless they are direct moves to slaughter.
Post import testing : There is no change to the policy regarding post import testing.
It is vital that everybody involved in the industry remains vigilant for bluetongue, continues to source livestock responsibly and to notify their local Divisional Veterinary Manager of any suspicion of disease.
Below is an explanation for the press release:
GB to be declared BTV8 free on 5th July 2011
GB has remained part of a Protection Zone for BTV8 since our first case of
disease in 2007. In June 2010 GB changed its status to Lower Risk Zone for
BTV8 which offered protection against the risk of disease from imported animals,
and was an important step toward BTV freedom.
EU requirements necessitate 2 years of evidence to demonstrate no active
disease circulation before BTV freedom can be declared. The results of our
bluetongue surveillance in 2009 and 2010 showed that all samples were
negative for all BTV serotypes, and the European Commission has accepted
GB’s case for BTV free status.
The BTV8 zones across England, Scotland and Wales will be removed on
5th July 2011, and all bluetongue restrictions on exporting sheep and cattle
from Great Britain will be lifted from this date. This means that a vaccination
against BTV8 will no longer be required before export from GB.
The Bluetongue situation in the rest of Europe also appears to have improved
significantly with no reports of active BTV8 circulation in any Northern EU
Member State. BTV Experts have advised that the threat of disease entering GB
via an imported animal or via windborne incursion appears to have reduced
considerably. Hungary, Austria, Denmark and Sweden have all declared disease
freedom recently.
The stringent conditions for animals imported from other Bluetongue zones
will remain in place. We will also continue to test high risk imports. It is vital that
livestock keepers continue to source responsibly and check the health and
vaccination status of their animals.
Currently the EU Bluetongue Directive (Council Directive 2000/75 /EC) only
permits vaccination against bluetongue within a protection zone. This means
that when GB is declared free of BTV8, vaccination will no longer be
permitted. Should any livestock keepers wish to vaccinate their stock, they
should do so before 5th July 2011 when the BTV8 zone is lifted.
We had anticipated amendments to the Bluetongue Directive which would permit
vaccination in bluetongue free areas, however these changes at European level
have been delayed and are now not expected until Autumn 2011. The
Government is continuing to press for changes at European level so vaccination
can be used more flexibly in future.
If and when changes are made, vaccination will be permitted once more across
GB, potentially for a wider range of serotypes. We will keep livestock keepers up
to date on latest developments with the Bluetongue Directive, and continue to
provide information on the latest disease situation in Europe.
Information on BTV Zones across the EU can be found at:
http://ec.europa.eu/food/animal/diseases/controlmeasures/bt_restrictedzonesmap.

All livestock keepers are reminded that suspicion of bluetongue disease must be
notified immediately to your local Animal Health and Veterinary Laboratories
Agency Office.

Health & Welfare Bulletin No.31 : General guidance
Are you animals up to date with their regular vaccinations ?
WORMING:
A number of you re-locate your animals to their summer grazing at this time of year. Check for worms before you move them. Either worm them or send samples to your vet for analysis. There is no point in taking worms to new pastures when it is so easy to prevent.
FLYSTRIKE:
Due to the weather conditions we have already had a number of instances of flystrike. Check your animals regularly. Look under the tail first as flies need warm, damp conditions to lay their eggs but look all over the animal.
SHEARING:
Although llamas do not necessarily need to be shorn, I have seen a number of animals recently that have long, very matted coats. It is not good for them to be like this. The wind blows and picks up the matt’s and the rain gets to the skin and that is when they get cold. Also it is difficult to see if your llama is loosing weight or if it gets fly strike, Think about having your animals shorn. There are a number of camelid shearers who are happy to shear llamas.
FEED:
Winter hay is going to be short again this year especially in the south and south east. Now is the time to contact your local farmer and put your order in. If you have space to store hay, ask if you can pick it up from the field as it may cost less. Last winter hay was being sold for as much as £10 per small bale, let’s hope we don’t have those prices this year !!
MICROCHIPS:
I still have a small supply of microchips at a cost of £4.15 each. Please send a cheque made out to British Llama Society together with a self addressed stamped jiffy bag if you wish to purchase any, to me at Nutfield Park Farm, South Nutfield, REDHILL, Surrey RH1 5PA.

Camelids
Currently camelids (llamas, alpacas, guanacos and vicunas) are not currently regulated in terms of registration and movement.
Whether you keep one animal as a pet or a commercial herd you need to be registered. Before moving animals to your holding you need to apply to the appropriate organisation shown below for a County Parish Holding (CPH) number for the land where the livestock will be kept.
Rural Payments Agency (in England and Wales)
Rural Inspectorate (Wales)(contact your local Welsh Assembly Government Divisional Office)
Rural Payments and Inspections Directorate (RPID) (Scotland)
BLUETONGUE:
The recommendation for 2011 from Animal Health is talk to your vet regarding vaccinating for Bluetongue this year. It is not being encouraged or discouraged by AH.
ANNUAL VACCINATIONS:
Are your animals up to date with their regular vaccinations?
WORMING:
A number of you relocate your animals to their summer grazing at this time of year. Check for worms before you move them. Either worm them or send samples to your vet for analysis. There is no point in taking worms to new pastures when it is so easy to prevent.
A very big thank you to all of you who took part in the worm survey sent out by Jacqueline Lusat. Hopefully an article will be written up for the Llama Link.
SURVEYS:
From time to time, BLS will be sending out surveys when we are approached by the animal authorities, i.e. DEFRA, AH, VLA and veterinary students. It is most helpful if these are completed and returned and I thank all who do respond. It is the only way we are going to learn more about our beautiful animals.

Health & Welfare Bulletin No.29 : Important Issues
Have you vaccination your herd this year ?
To date Bluetongue has not been reported in the UK and we wish to be part of the livestock industry to keep it that way. Please be responsible.
ANNUAL VACCINATIONS:
Are you animals up to date with their regular vaccinations ?
WORMING:
A number of you re-locate your animals to their summer grazing at this time of year. Check for worms before you move them. Either worm them or send samples to your vet for analysis. There is no point is taking worms to new pastures when it is so easy to prevent.
FLYSTRIKE:
Due to the weather conditions we have already had a number of instances of flystrike. One has even resulted in death !
Check your animals regularly. Look under the tail first as flies need warm, damp conditions to lay their eggs but look all over the animal.
LIVERFLUKE:
This is more common from September to November but due to the amount of rain we have had recently, some land is still boggy and wet. Your animal will lose weight and generally be subdued. It may have diarrhea but also may just be less active and stop eating. If suspicious, send a dung sample to your vet for checking. Be sure to ask for a liver fluke test.
DEATHS:
If you in an unfortunate position and find yourself with a dead animal, it is recommended that you send it away for a post mortem. This can be arranged by your vet. Under NO CIRCUMSTANSES BURY THE CARCAS – THIS IS ILLEGAL. It must be disposed of in a safe and proper manner. Your local Animal Health can give you name of your nearest abattoir.

Bluetongue Update
It is coming up to the time of year when we should all be administering the Bluetongue 8 booster to our herds or to begin protecting our new crias against the virus. At one of the various meetings I have attended on your behalf to discuss disease control, it was suggested that we use the same brand of vaccine for the boosters that you used last year. Please check this with your vets.

Health & Welfare Bulletin No.28 : Anti-TB Drugs
DEFRA advice to owners regarding the use of anti-TB drugs on
camelids suspected of having TB
Members are urged to take heed of the advice from DEFRA given below for the welfare of themselves, their own animals and the national alpaca herd.
DEFRA’s advice is that suspect clinical cases of TB should be notified to Animal Health and culled rather than treated with anti-TB drugs.
Owners need to be aware of the risks posed by treating suspect cases. Effective treatment of TB in humans is quite a complex, long and costly process involving a six-month course of at least three different drugs. To our knowledge, the effectiveness of such drugs and protocols has never been properly evaluated in South American camelids.
Assuming that an infected camelid will consistently receive the right dose of the appropriate drugs over a long enough period, it may remain infective to humans and other animals for some time.
Many treatment regimes, whilst seemingly capable of resolving the clinical signs of TB, will not result in a complete microbiological cure (elimination of all the bacilli) and may result in latent infections and potentially the development of drug resistance, resulting in serious public and animal health risks.
Additionally, owners need to be aware that by treating animals for TB they are jeopardising the only method of control currently available to infected herds (testing and slaughter of any positives) due to the suppressive effects the drugs may have on the immunological responses detected by the ante-mortem diagnostic tests. Animal Health may, therefore, be unable to undertake any TB testing of infected camelid herds if they become aware that owners are administering anti-TB drugs to some of their animals.

Health & Welfare Bulletin No.25 : MICRO-CHIPPING & CRIA REGISTRATION
Time to record your cria
'The BLS board is working hard to look after the interests of all members and their llamas. To do this it is vital that the llama register is accurate. In other species identification measures are enforced. For example all cattle must be registered with the national cattle movement services before they are two weeks old, must carry a passport, must have pre movement bTB test and must report all movements on or off the farm to the central registry; all equines must carry a passport and be microchipped; there are movement restrictions on pigs; and even sheep will have to be compulsorily microchipped from next year.
The BLS argue that we hold the national registry, can contact all owners and breeders quickly in the event of an emergency and that outside intervention is not necessary. If members are failing to register all births and sales, especially to non members, that argument begins to break down. If we cannot hold that argument, we cannot hope to represent the industry and protect our members from restrictive legislation.
Please register your cria NOW.
To record your cria (and your older animals if they have still not been added to the registry) is very straight forward.
All cria must be microchipped. It is recommended to microchip cria’s at six months old plus. To register your cria prior to the age of six months, just allocate a microchip to that animal and record it on your registration form. Don’t forget to get the cria microchipped once it is six months old. Chips from BLS cost £4.15 each which is an extremely good price. To obtain your microchips please send a padded self addressed stamped envelope, with a cheque made out to British Llama Society to Liz Butler, Nutfield Park Farm, South Nutfield, REDHILL, Surrey, RH1 5PA. Chips will be sent out within 48 hours.

Biosecurity Recommendations for UK Camelid Farmers
The aim of "biosecurity` is to prevent the introduction and spread of disease in susceptible populations or herds lo animals. Mainly we are talking about viruses, bacteria and parasites Below is a list of potential diseases and organisms that may be spread from animal to animal:
Gastrointestinal parasites (including worms coccidia and fluke)
Skin parasites, especially Chorioptes mites
Bacterial pathogens (e.g. Strap zooepidemicus Salmonella)
Mycobacteria (including M bovis (TB) and M avium subsp paratuberculosis (Johne’s Disease)
Viruses (e.g. llama adenovirus, respiratory viruses. equine herpesvirus-1)
Bovine Viral Diarrhoea Virus?
FMD?
Blue-tongue?
For the latter 3 viral diseases, the pathogenesis of potential disease in camelids and the effects of these viruses in terms of causing clinical disease in our species is largely unknown Further research is needed, but in the meantime, it would be prudent to include them in biosecurity considerations to try and minimize their effects. Essentially, biosecurity means protecting your existing herds from exposure to disease that may be brought in by new animals. and minimizing the risk oft spread of disease amongst newly introduced animals while also minimizing exposure to potential pathogens (disease-causing agents) that already exist on the farm. It is important to understand that animals may be clinically normal and showing no signs of disease while actually either incubating disease or being sub-clinically affected ‚ for example shedding coccidia although not having diarrhea. Therefore, it is not adequate merely to exclude animals that appear to be unhealthy as those that appear healthy (and may have passed veterinary health examinations) may still introduce disease onto your farm. A veterinary health certificate only shows that the animal appeared to be healthy at the time of the examination and does not certify the animal as free from disease It is also important to realize that the stress of moving animals from one farm to another, attending shows, changes in environmental conditions and social status can cause immune system suppression such that an animal that was previously healthy may be more susceptible to development of disease or may start to excrete the virus, bacterium or parasite, For example, it is quite common for an animal to have a negative fecal evaluation for parasites prior to transportation, and then several weeks later to find that the same animal has a clinically significant parasite burden, Commingling of animals at shows or while visiting breeding farms increases the potential exposure of animals to disease while also causing a certain degree of stress-induced immunosuppression For comparison, imagine a night spent on an aircraft traveling back from holiday - the effects of sleep deprivation (a stressor) suppress your immune system such that your body is less able to prevent the development of a cold from exposure to a cold virus breathed out by someone on the plane nearby.
We suggest following these practices:
1. Avoid introducing any animals that do not appear healthy to the rest of the herd.
2. Know the disease status lo any herd from which you are buying animals, or where your animals are being temporarily housed. Ask about current health status on the farm, but also previous problems with diseases such as gastrointestinal problems (diarrhea, parasites…) respiratory disease, abortion, ill-thrift or failure of passive transfer. Knowing that a particular farm had a problem with diarrhea for example is not necessarily a problem; knowing that the problem was identified, diagnosed and correct treatment and prevention measures employed should be reassuring and also shows that the farm knows what they are doing!
3. Insist on the pre-movement testing (PMT) and treatment of animals prior to their arrival. This is to show that they are at least as healthy as your own animals and requires that you have that same knowledge of the health status of animals on your own farm. There is little point in demanding testing of incoming animals unless you know that your own animals are healthy! Testing might at a minimum involve PMT for bovine TB by the comparative intradermal skin test or blood test as agreed, for BVD antigen (not antibody), and the treatment for endoparasites if required. No farm without an obvious chorioptic mange problem should accept a new animal with active lesions.
4. Isolate and quarantine all new animals before introducing them to the herd This includes animals that have been to shows or off-farm for breeding purposes since they have been commingling with other animals. lf you are introducing solitary animals, you may wish to place herd animals in the quarantine area to reduce the separation stress - choose less valuable animals for this such as geldings, avoid using breeding or lactating females.
a) Recommended quarantine period 30 days. This is the gold standard DEFRA and WAG may well in future introduce post-movement standstill orders of 5-7 days
b) Operate an all-in, all-out policy such that all animals housed in the quarantine area leave quarantine at the same time The quarantine period only starts from the time the last animal entered. Do not have animals moving in and out of the quarantine area on an individual basis.
c) The location of the quarantine site should be physically separate from the main herd as well as its handling facilities and housing. Ideally this should be several hundred yards away if possible and positioned such that it is downwind from the main herd but at the very least. there should be a double fence-line between the groups in order to prevent direct contact.
d) On a larger facility, have different staff working with the quarantine group and do not have the same staff return to the main herd. If this is not possible, tend to the main herd before tending to the quarantine group.
e) Wear clothing and footwear that is dedicated to the quarantine group when tending to this group - must be washable (e.g. wellies okay suede or fabric workbooks are not) Color coding of overalls is an obvious and visible reminder.
f) Monitor the animals in quarantine on a daily basis. Monitor attitude, appetite, water consumption, urination and defecation as well as for any signs of coughing, discharge from the eyes or nose, diarrhea etc. Animals showing any signs of disease should be further separated from the rest of the animals in quarantine and evaluated by a vet.
g) Evaluate a fecal sample on entry to the facility and 3 weeks later Ideally fecal samples should be collected every 3 days and stored in the fridge (Cebra 2007) If there is a subsequent problem with parasite-related illness or excretion then the source of the infestation can be determined. Treatment should be done if animals are found to have significant parasite burdens and their faeces retested 14-21 days later.
5. Minimize exposure of herd to human visitors. lf visitors come to the farm, question them about exposure to other livestock and where they have come from and make sure that they come to the farm wearing clean clothes and boots. Provide visitors with overalls and either Wellington boots or overboots kept on the farm for this purpose. Make sure that hand-washing facilities are available and that they are used.
6. Maintain optimum condition of animals in the herd. This will make them less susceptible to disease.
- under conditioning can cause problems
- provided. Mineral deficiencies can be responsible for disease problems in herds. Also, ensure that young growing stock receive sufficient vitamin D to prevent rickets
- shelter from rain, wind, cold and snow in the winter. Appropriate bedding (e.g. straw) may also be necessary for protection from cold.
a) Personal hygiene to prevent transmission of pathogens between animals and from animals to humans (known as "zoonotic disease”).
- Frequent hand washing with hot water and soap
- Cleaning and disinfection of boots
- Thorough washing of clothing used when caring for animals
b) Disinfection requires surfaces to be clean. All organic matter (faces, urine, milk, spit) must first be removed before disinfection can work on fences, floors, walls, clothing or hands. Disinfection may be difficult for certain organisms such as Cryptosporidia (which can also cause disease in humans) so is best avoided in the first place by following optimal biosecurity on the farm.

Health & Welfare Bulletin No.24 : Bovine Tuberculosis
Bovine TB is spreading out of control. Llamas are susceptible to bTB.
As many of you are aware there are an increasing number of llamas being found to have bovine TB. Although the mode of infection is as yet unknown, it is likely to be either llama to llama, cow to llama or badger to llama. This is very concerning especially as we, as an industry, do not have any workable systems in place to reduce the risk of infection.
TB is not caused by the owners lack of knowledge or by bad management. If you have infected animals you should not be embarrassed or ashamed. Our llamas and your fellow members need you to stand up and talk openly about your particular situation. This is the only way that others can become educated about the problem, how to handle it and what our rights are as llama owners.
What is needed from you
The BLS and the BAS have a meeting coming up shortly about bTB with the Government Minister in charge to put the camelid case to her. It would be very helpful if I could go knowing what it is that the members want.
I need your help to understand the extent of the problem. Unless those affected tell me who you are, I have no way of knowing how many of our members are affected. Your information will be treated in the strictest confidence, and will be known only to those on the board who are actively involved. As a relatively small industry we are much stronger when we talk as one. I can only do this if all those affected as well as those who may be in a hot spot come together and define what is required.
The first step is to let me know in the strictest confidence if you are affected. Please get in touch even if you think I already know.
You can email me: llamaliz@hotmail.com or call on 01737-823375. Once again, your information will be handled in confidence.
We, as representitives of the Camelid industry, can't go forward with this unless we know what you want. Those with infected herds know who you are. You have a duty to the greater livestock industry to eradicate bTB from your herds, to do this efficiently and effectively everyone needs to work together. Herds do recover from TB and there is light at the end of the tunnel. The future of llamas in the UK could be seriously damaged if we do not get to grips with this issue.
Thank you.

Microchipping
It has been very clear to the BLS Board that some form of mandatory identification and registering of all camelids is likely to be imposed by DEFRA. BLS already operates an effective registration system but so far has not asked members to use a method of identification such as ear tags or microchips. Nobody who owns a llama wants to see the mandated use of ear tags: they are unsightly but more importantly, because llamas are browsers, there is a real danger that they could be ripped out, leading to ear damage. Martin Hillson, one of our Welsh members, had a look at the pros and cons of microchipping and his article on the topic was published in the December 2008 Newsletter. Martin concluded that microchips were widely used in a variety of animals with a very low incidence of problems. Camelids are the only large animal now that DEFRA do not legislate for mandatory identification. Most animals have to be microchipped and ear tagged. We must be seen by DEFRA to be the responsible Society that we are and with our Registry and identification of animals in place, we feel this will be achieved.
The BLS Board has concluded that the use of microchips for the identification of llamas should be introduced from 2009. However the Board also felt that, since this was such an important and perhaps controversial topic, the membership should be asked to approve this move at the Annual General Meeting.
The final resolution for discussion and voting was: That all llamas changing ownership and all crias born after April 2009 must be microchipped. The resolution was well publicised before the meeting to allow members to join in the debate or to vote by proxy should they not be able to get to the AGM. At the AGM views for and against the proposal were put forward and debated, and the meeting overwhelmingly voted in favour of adopting this resolution.
The Society has purchased a stock of microchips at a very advantageous price of £4.15 each. They can be obtained by sending a padded SAE to Liz Butler, Nutfield Park Farm, SOUTH NUTFIELD, Surrey RH1 5PA together with full payment made out to the British Llama Society. This price is very reasonable and once the microchips are gone, a new quote will have to be obtained. Make the most of this great offer now.
Insertion tools can also be borrowed and the chips come with instructions on where they should be inserted in the necks of the llamas. This is easily done by your vet and can be combined with a vaccination visit to keep costs down. Reports from several members who have already had chips inserted is that it is quick and easy and causes minimum discomfort to the animal, none of whom have suffered any ill effects.
Health & Welfare Bulletin No.23 : Bluetongue
You should be aware that France have declared the whole of their territory as a BTV1+8 Protection Zone in order to allow compulsory vaccination against BTV1 in addition to the current voluntary arrangements in place for BTV8. This means that all animals moving from France to GB must now comply with BTV1 conditions before they can be moved. Broadly, this means animals being imported from France to the UK must be vaccinated against BTV1, and then serve a waiting period of 60 days (or quicker with a negative PCR test).
Health & Welfare Bulletin No.22 : Bluetongue & Liver Fluke
The recommendation from the Royal Veterinary College and the British Veterinary Camelid Society is to administer your booster vaccination of 1ml to camelids already vaccinated and two doses of 1ml to crias not vaccinated last year, in March/ April 09. There should be a minimum of 2 weeks between giving BTV8 vaccine and any other vaccination. It is also recommended that you try to use the same make of vaccine for the booster that you used last year. Please discuss this with your vet.
Recently, Liver Fluke has been reported as a big problem in camelids. A number of animals have been lost due to it. Know your animals and keep an eye on any abnormal behaviour such as progressive loss of body condition/weight, anaemia, pale membranes and swelling below the jaw (in severe cases).
Liver Fluke is easily treated so keep an eye on your stock for signs. If you are worried, please talk to your vet, it is better to be safe than sorry.
Health & Welfare Bulletin No.21 : Bluetongue
BLUE TONGUE DISEASE – DON’T IMPORT IT!
Following the discovery of Blue Tongue Disease (BTV) in England in 2007, no new cases of circulating disease have been found in 2008. This has been primarily due to the very successful vaccination campaign during 2008. It is estimated that over 90% of susceptible animals in East and South East England have been vaccinated. However, the uptake of vaccine has been much lower in other parts of the country and the overall coverage in the whole of England is thought to be only about 60%. Wales and Scotland have been running separate vaccination campaigns and there are no data yet on the coverage in those two countries.
There is a risk that the farming community might become complacent, thinking that BTV in Britain has been beaten and that there is no need to vaccinate again in 2009. Nothing could be further from the truth. One only needs to look at the latest map of BTV throughout Europe to see that the risk is not only still present but even greater than ever. BTV.8, the serotype found in England, has spread throughout most of Western Europe, with the exception of the Republic of Ireland and Portugal. It has spread as far south as Spain and Italy, north to Sweden and east to Poland, Hungary, Slovakia and Romania. Even more worryingly, BTV.1 has now spread to north-western France and BTV.6 has been found in The Netherlands. There is no vaccine available against BTV.6 and there is no cross-immunity between BTV.8 and BTV.1 or BTV.6.
Britain therefore remains at risk of re-introducing BTV.8 and of introducing BTV.1 and BTV.6 either by cross-Channel spread of vectors (which is how BTV.8 reached us last year) or by the legitimate trade in animals imported from other EU Member States. To control those risks, the British farming community therefore needs to:
- Carry on vaccinating against BTV.8 during 2009, giving boosters to all animals vaccinated during 2008, preferably before the vector becomes active in the Spring, and by vaccinating any animals born during 2009.
- Be very careful not to import disease when importing animals.
Because the BTV Protection Zone that covers all of mainland Britain is confluent with the BTV.8 PZ in Europe, there are no BTV-related restrictions applying to imports of live animals from within that PZ. In effect, it is just the same as moving animals from Kent to Lancashire.
However, there are risks in doing this as has been shown by the post-importation testing carried out by Defra. In 2008, at least 10 groups of imported animals have been found to be positive to BTV.8 virus and on 25 November, it was announced that a group of cattle imported from south west France were positive to BTV.1 virus. Fortunately, there has been no evidence that any virus circulated from these imported animals to other animals in the country and, in effect, we got away with it. But there is no doubt that these importations not only endanger our livestock industry and our exports but they are widely reported and give a dreadful image to the wider world.
The importation of BTV.1 infected animals has stimulated a widespread call from both veterinarians and farming groups to the livestock industry to stop importing animals from mainland Europe. After months of urging members to take care with European imports, the president of the NFU, Peter Kendall, has now called for an official ban. The President of the British Veterinary Association, Nicky Paull, feels the same way: “To me, it is very straightforward – stop importing from areas where the bluetongue virus is known to be circulating.”
There are legitimate reasons why the British livestock industry wishes to import animals but the message is loud and clear: Either make sure the imported animals are protected from BTV disease or risk having a complete ban imposed.
Minimum precautions:
All an importer needs to do is go back to the movement restrictions that were in place in the UK in the spring of 2008, when the vaccination campaign had begun and the PZ was limited to the south and east of England. At that time, to move animals from within the PZ to the Free Areas in the rest of Great Britain or for export:
1. The animals had to be vaccinated by a veterinary surgeon and be accompanied by a veterinary certificate of vaccination stating that: “I, the undersigned, being a veterinary surgeon, certify that I vaccinated the animals identified above….” giving details of the vaccine used and the date(s) the animals were vaccinated.
2. Either the full vaccination course had to be completed more than 60 days before the date of movement;
Or (i) The full vaccination course had to be completed at least 21 days before the date of movement, AND
(ii) The animals were subjected to an agent identification PCR test with negative results, carried out at least 35 days after the full vaccination course was completed.
Please be responsible. BLG urges all its members who are planning to import animals from areas of Europe where BTV virus is known to be circulating to act responsibly and insist on:
1. A veterinary certificate of vaccination.
2. An agent identification PCR test with negative results, carried out at least 35 days after the full vaccination course was completed.
By acting responsibly ourselves and urging our friends, colleagues and neighbours to do likewise, we not only improve the chances of protecting the British livestock industry from imported disease but also of negating the siren calls from others to ban all imports.

Health & Welfare Bulletin No.20 : Bluetongue
Order NOW for 2009
Defra are asking all owners of Camelids and all susceptible species to order their Bluetongue vaccine requirements for 2009 NOW in order to ensure sufficient vaccine is available for 2009.
Please let your own vet know how many doses you will require in 2009 so the vet can place an order for sufficient doses.
All animals vaccinated this year will need a Booster and all cria born in 2009 will need 2 vaccinations. The advice is to give the one Booster vaccination before the warm weather which means by the end of April, irrespective of when you gave the initial two jabs in 2008.
Scientists warn that the risk for 2009 will be considerable because of the spread of Bluetongue 8 in France with over 20,000 cases this year, as well as the risk posed by unvaccinated animals here. The French experience was that once an outbreak occurs it may be too late to vaccinate. Vaccinating animals with no symptoms but which have in fact already been infected, produces very sick animals indeed.
Vaccination is the only defence against Bluetongue 8.
Be very careful importing from Europe, many llamas appear not to have been vaccinated. Exporting from Holland and NW Germany is forbidden because of the outbreak of Bluetongue 6.
All imports irrespective of where they come from are tested for 4 sera-types 1,6,8,25. All of these strains have now been detected in Europe.
There are no UK licensed vaccines for sera-types other than BTV8.
