ABSTRACT

Three Eimeria tenella field isolates from Gurgaon district of Haryana (North India) were
studied in a battery test for evaluating the effect of currently used ionophores, maduramicin
(5 ppm) and salinomycin (60 ppm) on development of immunity. Broiler birds (Ross Strain)
were infected with 105 sporulated oocysts each at the age of 2 weeks (day 0) and prophylactic
medication commenced 2 days prior to infection. The birds were challenged with 2 x 105
sporulated oocysts each at the age of 4 weeks i.e. after a withdrawal period of 7 days. The
effect of medication on development of immunity was assessed by calculating the per cent
interference in the development of immunity for individual ionophore compound based on weight
gain, lesion score and mortality (per cent survival). Present study revealed negligible immunity
interference with Gurgaon isolate-I and III by both the ionophores whereas, slight interference in
immunity development was observed with isolate-II
