Abstract

It was assumed that the industry of beef cattle breeding being created in the Krasnodar Territory would meet the needs of the population in beef. Due to the fact that there are not enough beef cattle, dairy bulls are raised and fattened. Positive results are obtained in the case when, along with an increase in the number of the fattened livestock of animals, their intensive rearing and feeding is introduced. In our studies, with intensive rearing and fattening of the Holstein and Black-and-White bull calves, for the entire 14-month period of growing and fattening, average daily gains were obtained at the level of 1200 g, and the gross weight gain was more than 500 kg. According to the results of the slaughter of experimental bulls at the age of 14 months, we found that the Holstein bulls reliably exceeded the black-and-white bulls of the same age in all the studied parameters.

Summary

Introduction

Cattle breeders face the challenge of increasing beef production. It is possible to solve it in several ways, one of which is the breeding of beef cattle. The problem of increasing beef production is solved through the development of specialized beef cattle breeding, using intensive meat breeds [1, 5, 11]. The level of meat productivity of livestock and the quality of the beef produced depend on a number of factors. First of all, it is heredity, which manifests itself in one way or another, depending on the breed and individual characteristics of the animal. The most important factors influencing this indicator are environmental factors - feeding and keeping animals [2, 10, 15]
