Parameters of productive qualities of young people specialized meat breeds under conditions of Yakutia

Abstract

Relevance and methods. The article presents experimental data on the selection and genetic parameters of the productive qualities of young specialized meat breeds (Hereford and Kalmyk) in Yakutia.

Results. Musculature in animals of Hereford breed remained well developed, the animals remained well-fed. The skeleton is strong, in general, have strong and correctly set legs. The indices of elongation in bulls of Hereford breed were 114.5, the indices of incidence were 129.6, the index of chest was 56.6, and the index of pelvic was 87.1. In heifers of Hereford breed, the indices of elongation were 116.9, overgrowth 110.3, and bones 19.6. The dynamics of the live weight of young specialized meat breeds in the conditions of the farms of Central Yakutia shows that heifers and calves of the Kalmyk breed live birth weight was 19.2–20.8 kg, at 3 months of age 53.3–55.5 kg, at 5 months of age, 109.7–117 kg, respectively. In the period from birth to 3 months, the absolute increase was 34.1–34.7 kg with an average daily gain of 378–385 g.
