Meat productivity of sheep of Edilbaevskaya breed when using the probiotic Bacell

Abstract

Lamb meat is quite valuable in terms of food and a popular type of meat. Therefore, increasing the volume of its production is becoming one of the most important problems, both in our country and abroad. Studies by many scientists have proved that the best is considered to be lamb at the age of lambs 6-8 months. The purpose of the researches was to study the possibility of increasing the meat productivity of young sheep of Edilbaevskaya breed and increasing the nutritional value of meat through the use of the probiotic drug Bacell. Scientific and production experiment in the study of meat productivity of Edilbaevskaya sheep breed using probiotic Bacell has been carried out in the APC “Vladimirovsky” in the Akhtubinsky district in the Astrakhan region. In order to evaluate the potential of meat productivity of young sheep in a commercial herd after lambing 3 groups of ewes with 2-week-old lambs have been formed: the control group of animals was reared using traditional technology adopted in the farm, the 1st experimental group was reared and fed intensively due to additional feeding of grain mixtures, the 2nd experimental group was reared similarly to the 1st experimental, but additionally received the probiotic drug Bacell. By the end of fattening (6 months) the difference in slaughter weight in favor of rams of the 2nd experimental group compared to the 1st experimental group was 2,3 % (P ≥ 0,95) and 4,1 % (P ≥ 0,99) compared to the control group. Also, there was an age-related increase in the slaughter yield, which was for the analyzed period in the rams of the 2nd experimental group by 1 abs.%, and in the 1st experimental group by 1,8 abs. %, in the control group by 2,6 abs. %. The profit has been received from the rams of the 2nd experimental group was at the age of 4 months – 3281,6 rubles, and it was higher than the profit from animals of the control and 1st experimental groups by 1093,2 and 828 rubles. At the age of 6 months this difference was 714,0 and 316,8 rubles. As a result of the conducted researches, the expediency of using probiotic Bacell as a feed additive in the rations of young sheep of Edilbaevskaya breed has been proved.
