Continued selection of Romney sheep for resistance or susceptibility to nematode infection: Estimates of direct and correlated responses
Divergent breeding lines of Romney sheep, selected as lambs for consistently high or low faecal worm egg count (FEC) following natural multi-species challenge by nematode parasites, were established in New Zealand at Wallaceville Animal Research Centre in 1979 and at Rotomahana Station in 1985. In 1...
