Abstract

Abstract
Introduction
Sheep scab caused by Psoroptes ovis, is a disease of concern to many stakeholders in Wales due to its welfare implications. There are good diagnostic tests and treatments to deal with this issue but it remains a problem in flocks. Coordinated approaches are required to deal with this issue and these have been trialled in Wales.
Pilot design
Index farms are positively diagnosed using a skin scrape to identify mites. Contiguous farms are identified and antibody responses are then used to identify infested farms. All infested farms are treated by either dipping or injecting with approved products depending on farmer choice.
Results
Three index farms and 12 contiguous farms were identified and a total of 7 infested farms were found. Four were treated with dipping and 3 with an injectable ML product.
Discussion
In order to avoid reinfestation of farms, dealing with disease on contiguous farms is crucial. By having an external organising party, three local outbreaks were dealt with in a short space of time with appropriate diagnosis and treatment being carried out. Some farmers were uncooperative and strategies such as greater external support and veterinary involvement might alleviate these issues in the future. This approach is recommended to vets in the field when dealing with scab on farm.
