Effect Feed Additive "BIO-Extra" Produced By Different Technologies to Beef Production

In this work revealed positive impact new feed additive "bio-Extra" to productivity and quality indicators of meat calves. Best effect is had obtained by using a feed additive, which contained extruded chickpeas, pumpkin-silybum marianum press cake. Animals, which consumed feed additive RBIO-Extra, at the age of 16 months, surpassed by live weight analogues of control 19.0 and 25.0 kg with a significant difference. The calves which were consuming a feed additive with extruded components (chickpeas and pumpkin-silybunn marianum press cake) (II group) and as native form (I group), the difference in body weight was 6.0 kg. The average weight gain during the period of experience in the animals I and II experimental groups, was higher than control, by 101.1 and 143.9 g. Control slaughter results revealed that calves of experimental groups compared with control, carcass's weight was higher by 10.9 and 16.5 kg, slaughter weight 12.0 and 18.0 kg, carcass yield - higher by 0.40 and 0.92% and slaughter yield - 0.59 and 1.23%. Flesh weight of carcasses from calves consuming feed additive was higher by 10.7 and 17.7 kg, and its yield higher by 0.75 and 1.65%. The animals, which consumed feed additive, has improved chemical composition of meat. Average sample flesh of carcasses the dry matter contained more than analogues, 1.66 and 2.64%, protein - 0.73 and 1.05, fat - by 0.83 and 1.46%. The meat from calves of experimental groups has increased content selenium by 30.75 and 30.36, iodine by 36.59 and 47.16%. Biochemical analysis revealed that the eye muscle from calves has content of essential amino acid tryptophan was higher by 5.26 and 5.43%, and protein quality index by 0.50 and 0.58. Introduction to the diet for calves feed additive has increased the culinary and technological characteristics of meat. Water retention capacity of muscle increased by 1.16 and 0.52%.
