Влияние витаминно-микроэлементного комплекса на биологическую полноценность мяса

Abstract

On the domestic market of feed additives, we note a steady growth of new mineral and vitamin supplements, which differ in their composition and cost. The development and introduction into veterinary practice of feed additives that have a positive effect on the physiological state of the animal organism, contribute to an increase in average daily weight gain, safety, and also do not affect the quality and safety of livestock products is relevant for the manufacturer and animal husbandry. The article presents the results of a study of the vitamin-microelement complex «Trivit + Abioiodoselen» for broiler chickens of the Cobb-500 cross, according to the proposed scheme from 2 days of age to 5 days of age and from 15 days to 18 days of age at a dose of 1 ml per 1 liter of water. The introduction of this drug to broiler chickens in drinking water has a positive effect on the body of the bird, contributes to an increase in muscle tissue of selenium – by 12,8 %, iron – by 50,8 % in relation to the control group of broiler chickens. An increase in essential amino acids was noted in the experimental group of histidine– by 0,4 %; leucine + isoleucine– by 1,6 %; lysine – by 1,2 % and threonine – by 0,6 %, non-essential amino acids increased by 0,3 % tyrosine, 0,4 % serine and 9,0 % glutamate.
