Ten lambs of each of Najdi, Neimi and Hari breeds were inoculated with 400, 1600 or 16000 Haemonchus contortus third stage larvae (L3). The lambs developed subclinical forms of Haemonchus infection as they remained alert. The lambs maintained a steady growth rate, PCV values within the normal range, egg voidance tended to increase in all lambs proportional to dose of infective larvae and showed no significant (P>0.5) differences between the three breeds.
