Two experiments were conducted to determine the effect of inoculation of low levels of Eimeria tenella sporulated oocysts for the first one or two weeks of life (trickle infection method) on the development of specific immunity in chickens. Chicken inoculated daily at 1 to 14 days of age with 40 sporulated oocysts of Eimeria tenella provided better immunity than in the case of Chicken infected at 1 to 7 days only. This treatment was also preferable than those inoculated with 250 sporulated oocysts once at on 1 or day 7 or twice at days 1 and 7 of age. Immunity was provided when chickens were infected starting at the age of 1 to 7 days than that observed at a Later age of 7 to 13 days.
