Features of the infl uence of feed protein supplement Biovitel on the growth and development of steers of Hereford breed
One of the ways to increase meat resources is to improve the condition of livestock on farms in the Russian Federation. This is due to the fact that when the fatness of the animal increases, the meat yield in the carcass increases. The purpose of the researches was to establish the features of the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed. In order to achieve this purpose two groups of steers-analogs of Hereford breed (control and experimental) at the age of 6 months per 10 head in each have been formed. The time of the experiment was: the preparatory period of 22 days and the main one 275 days. Steers of the control group have received the main farm ration, and steers of the experimental group have received the main ration and feed protein additive Biovitel for 30 days with 10-days interval at the dose of 100 g per head during the sixth month. The results of researches on the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed have been refl ected in the article. The addition of the feed additive Biovitel to the main ration of the experimental group of steers helped them to achieve a higher live weight and higher average daily gains under the same environments of feeding and housing in all age periods. By the end of the experiment (15 months) the experimental group of steers have reached the live weight of 430,2 kg, which was higher by 19,9 kg or 4,9 % compared to the control group of steers. In order to improve the quality of beef and increase its production more intensive rearing of steers of Hereford breed with the use of feed protein additive Biovitel has been justifi ed. The recommended dose is 100 g per head. This dosage allows you to achieve the average daily gain of 967,5 g and the average live weight of 430,2 kg by 15 months of age, reduce the prime cost and increase the profi tability of beef production.
