Studies on Coccidiosis

THE results reported in this paper have been summarized from the work which has been carried in the department of Parasitology at the Louisiana Experiment Station during the past three years and include all inoculations made in all types of experiments in which the chicken received apparently virulent organisms which it was expected would produce some degree of infection or develop typical symptoms of coccidiosis. CONDITIONS OF REARING The chickens used in these experiments were S.C. Rhode Island Reds, incubator hatched and raised in a standard type battery brooder until 5 or 6 weeks of age. The same brand of commercial feed was used and the same methods of feeding closely adhered to in all of the lots. A large proportion of the eggs from which these chicks were hatched was obtained from the same flock of hens and the remainder from the daughters of some of the hens raised . . .
