Abstract
A very high level of protection was achieved against homologous (up to 97%) and heterologous (up to 87%) infections in 12-month-old Romney s heep immunised with oxfendazole-abbreviated infections of Ostertagia c ircumcincta and Trichostrongylus colubriformis. No significant protect ion occurred following ivermectin-abbreviated infections. None of the immunised sheep showed an increase in antibody level against excretory -secretory antigen of T. colubriformis infective larvae, The immunisat ion procedures did not cause a decrease in wool production, or livewei ght gains compared with non-immunised controls.
