Abstract: Increasing anthelmintic resistance (AR) in livestock has stimulated growing efforts to monitor anthelmintic effectiveness (AE) on livestock farms. On-farm assessment of AE relies on measuring the reduction in faecal egg count (FEC) following treatment; and… read more here.

DOI: 10.1093/jas/skad068.130
Abstract: Selection for post weaning worm egg count (PWEC) EBV has revealed that lowPWEC sheep have greater resistance to gastrointestinal nematode infection, greater survivability to weaning and generate greater anamnestic response to booster clostridial vaccination. Therefore,… read more here.

DOI: 10.1093/jas/skae019.105
Abstract: Post weaning fecal egg count (PFEC) estimated breeding value (EBV) has been recently linked with improved immune competence and lamb survival to weaning, thus improving health though selection. Animal movement is also linked to animal… read more here.
