Sheep Scab Treatment

 Resistance in scab mites to the injectables has been confirmed in the UK, which means we need to be increasingly careful about how we use both treatment choices.

There are only two treatment choices for scab – an endectocide (injectable) or an organophosphate dip (diazinon). Resistance in scab mites to the injectables has been confirmed in the UK, which means we need to be increasingly careful about how we use both treatment choices. Action is needed to both slow the rate of resistance to injectables and ensure mites do not develop resistance to OPs - more information here.

If you have treated sheep and they still appear to be infected (i.e. they are itching) it is important to report it to your vet and/or merchant. Do no just retreat, as this could waste your time and money and further add to resistance developing.

SCOPS has developed a simple protocol to go through when a treatment has failed. This is designed to:-

  • Safeguard the welfare of the sheep by ensuring appropriate actions (and treatments if required).
  • Avoid over use of treatments, especially of the same active class, by ensuring best practice and veterinary diagnosis are employed.
  • Report the suspected lack of efficacy to the Marketing Authorisation Holder (MAH) or Veterinary Medicines Directorate (VMD).

The livestock industry is an integral part of the agricultural sector, encompassing various aspects of animal husbandry and production. It plays an important role in global food security and supports the livelihoods of millions of people worldwide.

National Sheep Association (NSA) is an organisation that represents the views and interests of sheep producers throughout the UK.

Sheep scab is an infection caused by the mite Psoroptes ovis, which spends its entire lifecycle on the sheep. Unfortunately, it can cause significant health and welfare issues within flocks as it is highly contagious. Each year, the Welsh sheep industry loses £5.86m between treatments and loss of production. It also implies serious economic and welfare losses at farm level from reduced stock growth, lower reproductive rate, wool loss and skin damage.  Tackling scab is a challenge as sources of infections are not limited to one farm. Risks of infection are either increased by the presence of scabs within neighbouring flocks or reduced if those flocks are prophylactically treated. 

Sheep were one of the first farmed animals, reared for thousands of years for meat and milk.

Animal health is integral to the sustainability, profitability, and ethical considerations of livestock farming. It involves a combination of preventative measures, good management practices, and veterinary care to ensure that animals are raised in a manner that is both economically viable and environmentally responsible while prioritizing their well-being and public health.

If you’re responsible for a farm animal you must make sure that you care for it properly. (DEFRA)
