Efficiency of the New Fodder Additive for the Production of Lamb

Abstract

This article presents material on the study of the efficiency of raising Edilbayev sheep using a new feed supplement and assesses its effect on increasing the meat productivity of animals and improving mutton indices. To do this, we at Volgograd-Edilbay SGC LLC selected 30 animals of the Edilbayev breed of 7 months of age in two experimental groups according to the principle of pair-analogues with 15 animals each. The rams who received the standard diet were included in the control group, and their analogues, which were introduced a new feed additive in the diet, were included in the experimental group. The duration of the experiment was 105 days. In this case, the preparatory period of the experiment is 10 days, the transitional period is 5 days, the main one is 90 days. As a result of the experiment, it was found that at the end of the experiment, the rams of the experimental group exceeded their counterparts in the control group in live weight by 2.9 kg, or 5.72% (P≥0.999). As a result of the control slaughter, it was established that by the pre-slaughter mass, the rams of the experimental group are 1.65 kg or 3.35% more than analogues of the control group (P≥0.95); weight of fat tail fat - by 0.35 kg, or 13.21%; slaughter mass - by 1.49 kg, or 5.23% (P≥0.99); slaughter yield - by 1.09%, respectively. A study of the chemical composition of lamb showed that in the content of the rams of the experimental group in the meat, iodine was 0.08 μg / g more than the analogues of the control group (P≥0.95); silicon - at 3.92 μg / g; selenium - at 0.12 μg / g (P≥0.99); zinc - at 6.0 μg / g, respectively. According to the content of fatty acids, tail fat obtained from animals of the control and experimental groups differs in favor of the experimental group. Saturated fatty acids in turkey fat of animals from the experimental group contain 61.34%, which is 3.22% higher in comparison with the control group. Unsaturated fatty acids in animals of the experimental group contain 38.66%, which is 3.17% less in comparison with the control group. Thus, the highest results in meat productivity, chemical composition, and the amount of saturated and unsaturated acids were obtained from edilbaevsky rams that received a new feed supplement.
