Effect of level of infection by gastrointestinal nematodes and anthelmintic treatment on milk yield in dairy sheep

The effects of gastrointestinal nematode infections and anthelmintic treatment on milk yields was compared between flocks with a low level (LL) of eggs per gram (epg) before partum and with a high level (HL). Faecal egg count reduction tests (FECRTs) were carried out before partum comparing a treate...
