Live Weight and Productivity Indicators of Tavrian-Type Rams of Askaniya Thin-Corn Breed

Abstract

Breeding and breeding work with sheep of the Askanian thin-fleece breed is aimed at increasing meat productivity, creating precocious animals with well-defined meat forms and improved qualities of merino wool. The purpose of the work is to identify the features of productivity indicators of Taurian rams of the Askanian fine-wool breed, taking into account their live weight and using the obtained data during breeding and breeding work with animals. To conduct research, groups of lambs with different indicators of live weight were assembled: Group I - live weight up to 65.0 kg; II group - live weight 66.0-70.0 kg; III group - live weight of 71.0 kg and more. The total number of experimental livestock was 45 heads. The lambs of the third experimental group had a live weight of 73.0 kg. Their advantage over the rams of the first group was 10.8 kg, or 14.8%. The difference between the rams of the second and third groups was 5.0 kg, or 6.8%. A higher shearing of unwashed wool was also noted in the rams of the third group - 7.3 kg. Their advantage over the rams of the first group was 0.9 kg, or 12.3%, and the second 0.2 kg, which is 2.7%. The lambs with a higher live weight (III group) also had a higher cut of washed wool, which, respectively, amounted to 4.0 kg. The yield of washed fiber in rams had an optimal value for sheep of the Taurian type of the Askanian fine-wool breed and ranged from 50.0 to 54.8%. The difference in shearing of washed wool between lambs of the first and third groups was 0.8 kg, or 20.0%. According to such features as length, tone and density of wool, a significant advantage of the experimental stock over the regulatory requirements for the breed was noted. To pay special attention to the improvement of such parameters of wool productivity of Taurian type rams of the Askanian fine-wool breed, as the density and tone of wool, in particular, in animals with low indicators of live weight, which will positively affect the overall level of wool production in the farm.
