Immunization against Lamb Haemonchosis with a Recombinant Somatic Antigen of Haemonchus contortus (rHcp26/23)

Table 1

Number of adult Haemonchus contortus (females, males, total helminths) and recovery rate (as percentage of infective dose administered) recovered from the abomasa of challenged lambs at the end of the experiment. Helminth counts were log($x+1$) transformed. Numbers within brackets represent the parasite biomass (mg) determined. Data are average $\pm$ standard deviation.
