Schmallenberg Virus (SBV) Print E-mail

Please be aware that a new livestock virus that causes birth defects and miscarriages in cattle, sheep and goats has been confirmed in Britain for the first time.  The Animal Health and Veterinary Laboratories Agency said that tests on animals on four sheep farms in Norfolk, Suffolk and East Sussex had detected Schmallenberg virus.

 

This disease first emerged in the Netherlands and Germany in August 2011 and is thought to be spread by midges. Very little is known about it:  there is no antibody test as yet and adult animals that contract it apparently recover (subsequently possibly being sold abroad).  It is not yet a notifiable disease in the UK but farmers have been urged to report any suspicious cases. Officials suggest that the risk to human beings from the virus is very low.

 

Although in the UK the virus has only been found in sheep so far, it was originally diagnosed in heifers in Holland.  Apparently Russia has banned live imports of small ruminants from the Netherlands, Germany, France and Belgium and there could be a threat to live exports from the UK.

 

Symptoms include reduced milk yield, lack of appetite, loss of body condition and, principally in Dutch herds, diarrhoea.  Outbreaks of the disease typically last 2-3 weeks, and  individual affected animals recover over several days.   Since November 2011 there have been reports of miscarriages and stillbirths associated with congenital (present at birth) abnormalities affecting mainly sheep but also cattle and goats.

Included as part of the Guardian's article there is a map showing the disease distribution across the Continent......no doubt it is only a matter of time before it's found in cattle in the UK.

 
Proposed Bull Assessment Print E-mail

The Breed Development Committee of the Highland Cattle Society proposed the introduction of bull assessment, mainly as a means of weeding out poorer quality bulls. Council approved this measure, and now the process of consulting members of HCS to find the best way to carry this out has begun.

The professional examination by a vet to assess the health of the animal, undertaken at the breeder's expense, will remain a requirement. In addition it is suggested that bulls submitted for registration be inspected by two fieldsmen, who will together attend the breeder's farm to see the animal and submit a report with their recommendations.

A fieldsman's training day was held at Stirling in September, at which Jim Grant, a retired vet used to assessing Limousin and Aberdeen Angus bulls at Perth and Carlisle sales, spoke about mouths, locomotion and scrotal size. Fieldsmen need to take these factors into account, as an over or under bite can lead to serious problems, bad feet are undesirable in a hill breed, and scrotal circumference is apparently scientifically proven to have a bearing on the calf rearing ability of any heifer the bull may sire.

It is proposed that potential bulls be assessed in their normal environment, with the dam at hand and if possible the sire as well. Fieldsmen will be able to see the kind of land (height, hilliness, type of grazing etc) and judge the bull which has been bred to it taking these factors into account. Thus bulls should be able to be registered according to their fitness for purpose, so on high barren ground with poor grazing a smaller animal with excellent feet might be deemed more suitable than a larger animal with a good bite, which could be perfect for lower more lush ground.

It is not proposed that assessment should lead to breeding larger animals, nor that the maternal traits, including ease of calving, milkiness and hardiness, should be lost: this will be borne in mind when the bull inspection is carried out.

Members are being consulted as to what the next step should be, so if you have views on bull registration please send them to the HCS office in Stirling as soon as possible. All views raised in the consultation will be considered and reported on at the AGM in Oban in February, after which there will be another period for members to put forward their opinions before a final decision is taken by Council at its meeting in May.
