Influence of unconventional mineral mixtures on meat productivity of broiler chickens

The study presents the results of the influence of non-traditional mineral mixtures based on industrial wastes on the meat productivity of cross-country broiler chickens ‘Ross 308'. The research was carried out on the basis of LLC "YeniseyAgroUnion" Sukhobuzimo district of Krasnoyarsk Region and the farm of the Institute of Applied Biotechnology and Veterinary Medicine of FSBEI "Krasnoyarsk State Agrarian University". The effects of unconventional mineral mixtures on the meat productivity of cross-country broiler chickens ‘Ross 308' were studied. Control group chickens were given a balanced basic diet (BD) prepared according to the standards of ARIP, and in the diets of the test groups partial or complete replacement of limestone and monocalcium phosphate with oxidized brown coal, belite sludge, vermiculite and peat was carried out, the grain part remained unchanged. Mineral mixtures (based on industrial waste) used in poultry feeding were found to have a positive effect on the slaughter and meat qualities of broiler chickens. Two scientific and economic experiments were made. By the results of the researches of the first scientific and economic experiment it was established that feeding of mineral mix № 3 led to the increase in the mass of gutted and ungutted carcass by 0.04 % in comparison with control group (P≥0.95) and as a result to growth of slaughter exit up to 84.2 %. The use of mineral mixture № 2 based on industrial wastes in poultry feeding in the second scientific and economic experience had a positive impact on anatomical cutting of broiler chickens. Mineral mixture based on limestone, monocalcium phosphate, oxidized brown coal, belite sludge and vermiculite in the feeding of broiler chickens contributed to an increase in slaughter yield and mass of the shredded carcass by 7.72 and 28.77 %, as evidenced by the results of poultry slaughter.
