THE EXAMINATION OF POULTRY PRODUCTS WHICH WAS OBTAINED USING VITAMIN-MINERAL COMPLEXES WITH SELENIUM IN GROWING TECHNOLOGY
Aggregate-resistant vitamin-mineral complex has been created, based on selenium with a particle size of 20-60 nm with a complex of lipophilic and hydrophilic vitamins. It is used in the technology of growing broiler chickens, like the Cobb-500 cross. It was studied the effect of thise complex on the chemical composition of poultry meat, including in comparison with an analogue preparation. The ability to classify the resulting product as functional, due to enrichment with selenium, has been established. Group 1 was a control. Group 2 broilers consumed a developed aggregate-resistant vitamin-mineral complex with drinking water. Group 3 chickens used the analog drug “Solvimin Selen”. The use of vitamin-mineral complexes based on selenium in the diet of broiler chickens not only does not adversely affect the quality of meat products, but also has a definite positive effect: the minced experimental groups had more protein and less fat. A significant increase in dry protein content from dry matter was in the samples of the femoral muscles of group 2 - 9.84%, of group 3 - 12.70%. A significant decrease in fat content is characteristic of both the pectoral and femoral muscles. The cumulation of selenium in the thigh muscles in groups 2 and 3 exceeded the control parameters by 32% and 40%, respectively, in the liver - by 59% and 55%, in the heart - by 40% and 45%. The resulting poultry products can be classified as functional and, in accordance with GOST R 55577-2013, have the additional marking "with a high content of selenium ”.
