Table 1.
Faecal egg counts (FEC) of 20 first-season grazing calves for each of the 19 Danish farms sampled during initial screening in the 2013 and 2014 grazing seasons. A total of 380 first-season grazers were examined. Data are presented as arithmetic mean FEC, range (in egg per gram of faeces, epg) and the date of sampling. Six farms (farms #1–6) were included in the subsequent faecal egg count reduction tests (FECRT).

Despite high FEC this farmer did not want to participate in the FECRT.
b
Turn-out of grazing cattle in Denmark is usually around late April/early May.
