version: PREBIOTIC DRUG "KORMOMIX MOS" IN THE TECHNOLOGY OF RAISING YOUNG SHEEP

Abstract

The results of the use of the prebiotic drug "Kormomix MOS", when growing sheep of the Stavropol breed up to 8 months of age in semi-desert conditions are presented. During the period of the lambing campaign, two groups of queens with sheep aged 30 days were formed in the flock of sheep. Lambs were selected according to the method of analogues of 20 heads in each group. For separate feeding of lambs inside the sakman cages made of wooden shields, "canteens" with an area of 15 m2 were equipped. The prebiotic drug "Kormomix-MOS" is 5 g per head per day for 30 days. Its positive effect on the increase in live weight and meat productivity has been established. According to the live weight, the superiority of the animals of the experimental group over the control ones was 1.95 kg or 5.6% (P>0.999). The experienced animals had the best meat qualities. According to the pre-slaughter weight, the excess was 5.2%, according to the mass of chilled carcasses, the advantage was 1.16 kg (8.3%), respectively. The lethal yield was also 42.2 % in the experimental group, and it was 41.13% in the control group, respectively. The analysis of the yield of cuts by varieties also indicates that in the carcasses of animals of the II experimental group, the yield of first – class cuts-hip, lumbar and shoulder-spinal, was greater than in the control ones by 0.5%. In terms of morphological composition, the carcasses of group II sheep exceeded the control in terms of the yield of edible parts (pulp) by 0.91%, the meat content coefficient - by 0.06 and the area of the muscle eye – by 0.21 cm2 or 2.1%. When cutting carcasses into anatomical cuts, the advantage of experimental animals over control animals was also established. The average shoulder-spinal cut in the group of experimental animals was 6.57 kg, and the hip cut was 4.29 kg, which exceeded the control ones by 8.2% and 8.9%, respectively. No significant differences were found for the remaining cuts. The mass of the internal organs of the experimental animals was generally greater than that of the control animals, but there was no statistical difference.
