摘要: Abstract Targeted selective treatment (TST) has been proposed as a sustainable method of gastrointestinal nematode control that reduces the number anthelmintic treatments administered, thereby preserving susceptible population in refugia. In order to minimise impact withholding on animal performance, animals would benefit most should be selected for treatment. However, suitable criteria selecting which treat remain subject research. The implementing TST strategy based lamb live weight was investigated, and whether heavy lambs were more resilient than light if left untreated. study conducted using weaned 3 sheep farms, over 2 years. On each farm weighed divided into heavy, medium classes. Within (n = 225) (n = 218) classes randomly allocated two treatments; or no All class treated. Animal performance parasitological parameters assessed 28-day period. Anthelmintic had significant effect (P
