Maksimovska S. Correction of productivity of turkey chickens of the white broad-chested breed with BAYKAL EM 1U probiotic under different growing conditions.

This thesis is based on the study of the effect of BAYKAL EM 1U probiotic on tur-key chickens of the white broad-chested breed in relation with different microclimatic pa-rameters (temperature, humidity, carbon dioxide, ammonia, hydrogen sulfide, illumina-tion) and raising technologies at the farm and Borki daughter enterprise of the Research Institute of Poultry Raising at the National Academy of Agricultural Sciences of Ukraine - on the live weight dynamics; on the morphological and humoral defensive factors of natu-ral resistance; on the determined features of growth of turkey chickens under optimal and adverse raising conditions, and their preservation in critical periods of their life. The find-ing of the research show that application of BAYKAL EM 1U probiotic to the turkey chickens positively effects their gravimetric and somatometric qualities. Application of the preparation to the turkey chickens under the poor zoohygienic raising conditions is reason-able, however, such an application alone cannot correct microclimate and feeding to opti-mal. Deviation of standard microclimatic parameters in the poultry yards (temperature by 6°С, relative humidity by 10%, air motion by 50%) involves the decrease of the body de-fenses and of the average daily amount of grow by 31.1%, and the increase of losses by 3.3%. For the first time, scientifically substantiated doses of BAYKAL EM 1U preparation, which are 0.2 and 0.4 ml/kg of live weight, are proposed for industrial application in rais-ing meat turkey chickens. Adding BAYKAL EM 1U preparation to the diet of turkey chickens does not impair factors which characterize the slaughtering and meat properties, organoleptic and techno-logical properties and its biologic values.
