COMPREHENSIVE BIOPROTECTION OF BROILER ENTERPRISES FROM EIMERIOSIS

A set of veterinary and sanitary measures was presented for the bioprotection of broiler enterprises from parasites (Eimeria of broiler chickens). The set of veterinary and sanitary measures provides a reduction in the number of Eimeria oocysts in broiler chickens on the floor and in hard-to-reach places for washing, disinfection and disinvasion. The necessity was emphasized for monitoring the epizootic situation on eimeriosis of broiler chickens and tick infestation (litter mites of the genus Tyrophagus spp.) in winter, spring and autumn periods of the year to establish the infection prevalence and intensity in the technology of litter-free broiler growing. The research results made it possible to assess the level of biosafety, prevalence (IP) and intensity (II) of coccidia and tick infection. The Eimeria spp. infection intensity was determined according to the Methodical Guidelines and estimated as low and average. Modern comprehensive measures on the poultry farm along with therapeutic and prophylactic treatments, namely, disinvasion with a 5% working solution from a preparation based on 1% glutaraldehyde, 7% glyoxal, and a mixture of 25% QAC (quaternary ammonium compounds) against coccidia Eimeria spp. oocysts during the period of premises preparation, and therapeutic and prophylactic treatment with a coccidiostatic agent based on 12% salinomycin mixed with feed, on a regular basis, make it possible to significantly reduce and minimize the pressure of eimeriosis.
