The study included 1000 saliva samples from horses at a UK welfare charity from autumn 2015 to autumn 2016. Samples were predominantly collected in autumn and spring using a commercial test (Equi- Sal®) that measures tapeworm-specific antibody levels in saliva samples to give a score of low, borderline, moderate or high. Horses with a score of borderline or above are considered to require anthelmintic treat- ment. representing an 86% reduction in administration com- pared to blanket biannual use. Despite this, the preva- lence of tapeworm infestation did not increase over the study period. Bottom line: Biannual use of the saliva test may be an effective method of monitoring for tapeworm infes- tation and directing treatment to affected individuals, reducing selection pressure for resistance. ______________________________________________ D.G.

Only 3% were above treatment threshold in all three tests. Younger horses required more treatments: 55% of 1- to 5-year-olds on at least one occasion and 26% on more than one occasion. Notably, 41% of new arrivals to the herd had antibody levels above treatment threshold, highlighting the importance of testing horses introduced to a herd. During the study period, 99 doses of praziquantel were administered, 8 • Equine Health Update •
