Action on slow finishing lambs
This is a common problem, with many potential causes, including:
• Stomach and intestinal worms
• Liver fluke
• Mineral deficiencies
• Chronic infections in lambs
– Lung abscesses, liver abscesses
• Poor mothering – insufficient colostrum and/or milk
– Chronic infections in the dam e.g. iceberg diseases
– Barber’s pole worm, fluke, Johne’s, MV, OPA, mastitis
• Undernutrition – has there been enough grass in front of them?
Often, by the time the problem is evident in autumn, the underlying cause has been and gone. Investigation of tail end lambs can frequently be frustrating if for example, the damage was done several months ago by gut parasites. Mineral deficiencies are often masked by the concentrates purchased to fatten these lambs. On farm post mortem examinations of any lost lambs are often a fair place to start. If nothing else, it is useful to check for evidence of liver fluke and previous cases of pneumonia. If the problem was parasites much earlier in the year, the damage to the lining of the gut is devastating but microscopic.
Being proactive about slow finishing lambs
Start three weeks before lambing, making sure ewes are being fed according to their needs. Soya is frequently limited in commercial ewe concentrates. Speak to your vet about feeding and metabolic profiling of ewes.
Next stop would be to ensure all lambs receive their fair share of colostrum, getting 10% of their body weight in colostrum in the first 18 hours, half of that in the first 6. This is crucial.
Check dung samples from 3-4 weeks of age with respect to coccidiosis. By the time lambs are scouring and obviously affected, lot of gut damage has happened.
Eight week checks on lambs and ewes: target growth rates in lambs should be in excess of 250g/day up to eight weeks. Check ewes BCS to plan ahead for when weaning needs to happen.
Weaning: if you are creep feeding, you should aim to have sold 60% of lambs by this time. If not creep feeding, DLWG from 8 weeks should have been over 200g/day.
Post-weaning: set stocked lambs should have sward heights of 6-8 cms.
Trace element profiling is best done on rapidly growing lambs not being fed any creep or mineral supplement. Yard lambs just before the vet is due as being without feed for a few hours can affect results.
Worm egg counts are useful in all systems, but very important in sheep only enterprises. Here, they are the best way to assess when to worm to limit pasture contamination, as “safe” grazing will be limited.
Cull ewes and ewes still thin some weeks after weaning can be blood sampled for iceberg diseases which may have limited milk supply.

Godfray Bovine TB Review – key findings
A review of the government’s 25 Year Bovine TB (bTB) Strategy, led by Sir Charles Godfray, was published in
The report, which was commissioned by Environment Secretary Michael Gove in February, aims to inform future strategies around the government’s goal of eradicating the disease by 2038. The findings from the report include:
• Evidence shows badgers do transmit bTB to cattle and contribute to the persistence of the disease.
• Control of bTB in badgers is necessary and inclusion of non-lethal methods (vaccination) is desirable.
• The bTB skin test misses too many infected animals.
• Industry must take greater responsibility for on-farm controls, biosecurity and safe trading practices to stop spread of disease.
• A strong argument exists for disincentivising risky trading by reducing compensation for slaughtered cattle.
• More can be done to help farmers with risk-based trading. (TBAS offers advice on purchasing decisions reflecting the risks of buying in infected cattle.)
• The number of cattle movements in England is very high and will inevitably be a risk for disease spread. Analysis is needed to see if the benefits outweigh the risks.
Remove BVD from your heard: The BVD Stamp It Out Initiative
Substantial RDPE funding has become available to all cattle farmers (dairy and beef, breeders and rearers) to start or continue or take their herds’ BVD control to the next level.
This funding includes farmers meetings, individual farm visits, up to £60 worth of initial check testing with the potential for further funding towards eliminating Persistently Infected cattle (PI’S) from confirmed ‘infected’ herds.
Accessing the funding is easy: come along to one of the local Torch Farm Vets BVD STAMP IT OUT meetings and we will get you signed up and started on the process.
We have secured funding for a significant number of North Devon clients, so don’t miss out on this opportunity.
Keep an eye out on social media for the next available dates and call your local Torch branch to secure your place.
We’ll meet at a pub local to you, discuss the initiative and see how best it can benefit your herd with lunch provided.
The first meeting will take place on Wednesday 12 December from 12-2.30pm at the Muddiford Inn, Muddiford EX31 4EY.
Please RSVP to your usual practice or by email to firstname.lastname@example.org.

Thoughts from our SQP…
Julie Rottenbury is our Group Pharmacy Supervisor (SQP). Jules is available for advice on parasites, nutritional products and selected vaccines.
Fluke has been a bit of a surprise this year, after the dry summer we were expecting this autumn to be low risk, however stock have been attracted to the damper parts of the fields to find the best grass (only grass!)
This has resulted in autumn 2018 being at least medium risk.
The most effective flukicide at this time of year is Triclabendazole. The fluke doing damage right now are juveniles and triclabendazole is the only active to kill very young flukes. Nitroxil and closantel will target teenage fluke and adults. If these products are used, then the dose needs to be repeated. If you have any suspicions about resistance to triclabendazole on your farm, please speak to your vet. If you suspect you are not a “flukey” farm, there are diagnostic tests we can do which will show exposure or not and determine whether you do have a need to treat.
Remember: target the parasite – use the right product at the right time.
