Application of biological engineering methods to improve the productivity of Tuvan short-fat-tailed sheep

Abstract

This article presents the results of many years of research on the use of semi-coarse-wool breeds to improve Tuvan short-fat-tailed sheep. On the basis of the assessment of biochemical and biomechanical parameters of experimental animals, the schemes of interbreed crossing are proposed. A comparative analysis of the data on the exterior and productive indicators of hybrid offspring of different generations, their adaptability to natural-climatic and forage conditions was carried out. The calculation of productivity indices showed the validity of the proposed bioengineering approach to improve economically useful characteristics of sheep.
