Abstract

84 first-year grazing Holstein × Friesian steers were observed for 2 years on 40 ha of reclaimed unfertilized grassland. Three groups of steers were grazed each year at low, medium and high stocking rate (SR) in separate paddocks (0.53, 1.05 and 1.55 steers/ha). The faecal egg counts, predominantly ...
