The influence of the carbohydrate complex “Felucene” K 2-4 and K 2-6 on the beef productivity of steers of Hereford breed

Abstract

Feed additives in the feeding of growing animals are able to meet their nutritional needs for the manifestation of high productivity indicators, since their main purpose is to optimize the ration of animals for energy, protein, macro– and microelements, vitamins and biologically active substances in accordance with feeding standards. The purpose of the research was to increase the productive traits of steers of Hereford breed, taking into account the consumption, digestibility and use of feed nutrients when consuming the carbohydrate complex “Felucene” K 2-4 and K 2-6. Scientific and economic experiment was carried out in OOO “Berezovskaya farm” in the Pervomaisky area in the Tomsk region. The steers of Hereford breed were divided into 4 groups according to the principle of groups of analogues: the 1st control group received a ration without additives, and the experimental ones (2nd, 3rd and 4th) with additives that were administered according to the developed scheme. In the period from 6 months to one year of age the steers were fed the carbohydrate complex “Felucene” K 2-4 at a dose of 50, 100 and 150 g/head/day, and then up to one and a half years of age the carbohydrate complex “Felucene” K 2-6 at the dose of 100, 150 and 200 g/head/day, respectively, in groups. It was found that the maximum slaughter yield was recorded in animals of the 3rd experimental group, which was 60,9 %, and the minimum was in the 1st control group 59,6 %, the average values were in steers in the 2nd and 4th experimental groups. There was a similar distribution of groups by carcass yield. The predominant position in all slaughter indicators was occupied by young animals of the 3rd experimental group, who consumed the tested drug in doses of “Felucene” K 2-4–100 g/head/ day and “Felucene” K 2-6 -150 g/head/day. Studies have shown that the use of carbohydrate complexes “Felucene” K 2-4 and K 2-6 in the dose of 100, 150 g/head/ day and 150, 200 g/head/day as part of compound feed in the rations of steers during the rearing and fattening period is a reserve for increasing the efficiency of beef production. Moreover, the best economic indicators were observed when feeding the tested additives in the amount of 100 and 150 g per animal per day.
