Rabbit breeding is one of the promising branches of animal husbandry, but its development is hampered by various diseases. The problem of the pathogenic influence of parasites of the genus Eimeria on the organism of rabbits at different infective doses is still quite urgent. The study was conducted on hybrids of rabbits of Soviet Chinchilla and Californian breeds at 30 and 45 days of age. Within the framework of the experiment 6 groups of young rabbits were formed by the method of pair-analogs. The one-day old rabbits in the experimental groups were infected with oocysts of the association of Eimeria species E. perforans and E. irresidua at doses of 100 000 (2 groups) and 200 000(2 groups) per head, and in control groups (2 groups) - remained intact throughout the experiment. To analyze the pathogenic effect of parasites determination of meat productivity, veterinary and sanitary assessment of carcasses, linear measurements of intestinal length as well as histological studies of the walls of the small intestine were carried out in rabbits of these age groups. The research results showed that rabbits-hybrids infected at a dose of 100 000 and 200 000 oocysts per head demonstrate significant reduction of the increase in live weight and slaughter yield, despite the preservation of the retail display of the carcasses.
