Evidence-based indicators to support targeted (TT) and targeted selective (TST) anthelmintic treatments against gastrointestinal nematodes in ruminants.

	Young cattle	Adult cattle
TT indicators	Grazing management	Grazing management
	Mean FEC after 4–8 weeks during first grazing season	Bulk tank milk anti Ostertagia ostertagi antibody level
	Mean serum pepsinogen level at end of grazing season and/or housing	Time of effective contact with gastrointestinal nematode larvae based on qualitative analysis of grazing history until first parturition
TST indicators	Live weight gain
	Body condition score in combination with FEC
