Selection of quantitative traits when crossing thin fine-coarse wool sheep with Tsigai breed rams
Year: 2021
Type: conference-paper
Abstract: It is shown, that uncontrolled mass crossing of sheep with homogeneous wool led to a sharp deterioration in the quality of wool and the appearance in herds of a large number of fine- wool-coarse-wool hybrids not suitable for breeding. The experience of work on the restoration of fine-fleece and semi-fine fleece herds from such crosses is reported. The research on the dynamics of productivity and quantitative useful traits during the transformation of hybrid sheep into Tsigai is presented. The correlation dependence between the quantitative traits and the coefficients of heritability of the quantitative traits of Tsigai and crossbred sheep, as well as the variability of the quantitative traits of these sheep are shown. With the absorption of Tsigai by rams of fine-coarse-wool hybrids for one and a half intervals between generations, it is possible to increase the proportion of half-fine wool in a flock of sheep by 3-4 times.
