Получение биологически полноценной продукции птицеводства при применении комплексного витаминизированного препарата

Abstract

The article presents the results of studies of the effect of the complex fortified preparation of domestic production «Nitamin» on broiler chickens and the biological usefulness of the resulting meat. The experimental part of the work was carried out in the vivarium of the Department of Parasitology and Veterinary and Sanitary Expertise of the Federal State Budgetary Educational Institution of Higher Education of the MGAVMiB-MVA named after K. I. Skryabin. The drug «Nitamin » was given to broiler chickens with drinking water at a dose of 1 ml per 1 liter of drinking water, according to the scheme from 2 days to 5 days and from 15 days to 18 days, the birds were slaughtered on the 42nd day of keeping. The material for the research was the muscle tissue of broiler chickens of the experimental and control groups, the determination of the content of the amino acid composition, as well as trace elements of selenium and iron, was carried out in accordance with GOST R 55569–2013 Feed, compound feed, compound feed raw materials. Determination of proteinogenic amino acids by capillary electrophoresis, GOST 31707–2012 (EN 14627:2005) Food products of trace elements. Determination of total arsenic and selenium by atomic absorption spectrometry with generation of hydrides with preliminary mineralization of the sample under pressure and GOST 30178–96 Raw materials and food products. Atomic absorption method for the determination of toxic elements. The studied meat samples of broiler chickens, which were fed with the drug «Nitamin», have an increased biological value, the amount of essential amino acids increased by 14,38 % compared to the control. When studying the content of trace elements in the muscle tissue of experimental broiler chickens, an increase in the iron content by 81,8 % was noted in relation to the control group.
