Abstract

The article presents the results of studies of the indicators of live weight and the internal organs weight of purebred Khalkha and crossbreed Khalkha-Suffolk rams, depending on the method of their fattening. Experimental studies were conducted in the Selenga aimak of Mongolia and in the laboratories of the Mongolian University of Natural Sciences. According to the results of the research, it was revealed that purebred Khalkha rams were inferior to Khalkha-Suffolk crossbreed rams in terms of live weight at birth and at the age of 8 months. When fed with rapeseed cake, purebred Khalkha rams had an advantage over half-breeds in terms of absolute heart weight by 0.04 kg and digestive system weight by 0.06 kg, and in terms of pre-slaughter weight by 0.22 and 1.29%, respectively. At the same time, Khalkha-Suffolk crossbreed rams outperformed purebred animals in terms of absolute lung weight by 0.19 kg and relative weight by 0.19%.

Highlights

The extensive use of the internal organs of domestic animals as food is an important strategic resource of humanity in dietary protein provision
The purpose of this study is to determine the effect of top dressing with rapeseed cake during feeding on the indicators of live weight and weight of internal organs of purebred and crossbred young animals
Data from measurements of the internal organs of young sheep of the Khalkha breed and Khalkha-Suffolk crossbreeds make it possible to determine the potential possibilities of their use in the food industry of the Mongolian People's Republic

Summary

Introduction

The extensive use of the internal organs of domestic animals as food is an important strategic resource of humanity in dietary protein provision. Meat production and supply reflect the amount of whole meat, but do not take into account the resources and consumption of internal organs, such as the heart, liver, kidneys, etc. The purpose of this study is to determine the effect of top dressing with rapeseed cake during feeding on the indicators of live weight and weight of internal organs of purebred and crossbred young animals. The research objectives were to study the effect of feeding young animals of different breed groups with rapeseed cake during fattening: on live weight indicators on internal organs weight. Data from measurements of the internal organs of young sheep of the Khalkha breed and Khalkha-Suffolk crossbreeds make it possible to determine the potential possibilities of their use in the food industry of the Mongolian People's Republic
