The article presents the results of the influence of the mineral mixture using local raw materials on the physiological parameters of broiler chickens of “Ross 308” cross. The studies were conducted on the basis of YeniseiAgroSoyuz LLC of the Sukhobuzim district of the Krasnoyarsk Territory, and the stock-raising farm of the Institute of Applied Biotechnology and Veterinary Medicine of FSBEI HE Krasnoyarsk State Agrarian University. The aim of the research was to study the effect of the mineral mixture using local raw materials in feeding broiler chickens. It has been found that a mineral mixture containing limestone, monocalcium phosphate, oxidized brown coal, belite sludge, peat, and vermiculite improves the nutrient digestibility of broiler chicken feed.
The research results of the measurements of biochemical and hematological blood parameters of broiler chickens of the cross “Ross 308” depending on the inclusion of mineral additives based on industrial wastes into diet are presented in this article. The researches were conducted in 2017 at the premises of LLC “YeniseiAgroSoyuz” of Sukhobuzimsky district of Krasnoyarsk region and the stock-raising farm of the Institute of Applied Biotechnology and Veterinary Medicine of Krasnoyarsk State Agrarian University of the Ministry of Agriculture of Russia. The purpose of the research was to justify the use of mineral sources of Krasnoyarsk region as a part of animal feed for poultry. It has been established that the use of belite sludge and oxidized brown coal is one of the promising areas of non-waste technology for processing and mining of alumina and brown coal in the territory of Krasnoyarsk region.
The assessment of perennial legume-grass plants for pasture purposes was carried out on the basis of data from field experience conducted in the forest-steppe of Krasnoyarsk region and data from a qualitative analysis of pasture grass mixtures. The content of macronutrients: calcium, phosphorus, magnesium; green mass yield, collection of dry matter and feed units in three grazing cycles were determined. The chemical composition and productivity of pastures were depended on the type of grass, the cycle of grazing and the composition of the mixture. It was noted an increase in the calcium content in grass mixtures by 3.2-3.9 times to the control of red fescue. The phosphorus content in pasture feeds was at the control level. A higher content of magnesium in comparison with the control was found in the herbal mixture of brome + cat’s-tail grass + red fescue + goat’s-rue + clover. A grass mixture of brome + cat’s tail grass + red fescue + lucerne was the best in terms of yield of green mass, collection of dry matter and feed units.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
