COMPOSITION OF FEED FOR GROWING TURKEYS CROSS BIG-6
The article analyzed the chemical composition of the feed structure and the provision of nutrients complete feed for turkeys cross Big 6 age periods. We were founded optimal levels of nutrient concentrations in the complete feed. According to the FAO for the 2012-2042 biennium the number of turkeys in the world has increased to 846 217 thousand or 106%, while the production of turkey meat has increased from 5610 to 6120 thousand tons and was 1.1 kg per person per year. Currently RF consumes 0.72 kg per year turkey population in view of imports, while in Israel - 15 kg in the UK - 7 kg, in US - 9 kg. Growth turkey industry efficiency can be achieved by improving the genetic potential of the birds breeding work aimed at improvement of the existing and creation of new highly productive breeds, lines combine well in crosses and hybridization. The effectiveness of selection and breeding work in the poultry industry is largely determined by the level of genetic research, the development of theoretical and practical bases of breeding, as well as the optimization of feeding and poultry. The high level of productivity of poultry is based on obtaining heterosis effect, which manifests itself by crossing specialized paternal and maternal lines. The rational organization of production can be carried out only in the presence of well-functioning system of breeding poultry farms to obtain commercial poultry. Modern Russian turkey is mainly focused on foreign hybrid hatching eggs and day-old poults white broad-breed heavy type. Also breeding material is delivered in a small volume. However, in the case of undesirable sanitary-veterinary, economic and other situations in the importing countries, the economy in our country will not be able in the future to produce turkey meat, which once again proves the necessity of the development of the domestic turkey breeding to maintain the country's food security.
