Correlation coefficients of F1 hybrids obtained from crossbreeding of uzbek meat-wool ewes with purebred dagestan breed rams

Abstract

The article presents data on the fact that the correlation coefficients between the selection traits of F1 hybrid rams born from the crossbreeding of purebred Dagestan breed rams and meat-wool ewes are higher than those of pure meat-wool equals. For example, in Group I at 12 months, F1 hybrid female lambs born from the crossbreeding of purebred Dagestan breed rams and meat-wool ewes demonstrated a high positive correlation coefficient between wither height and oblique body length +0.600, rump height with wither height +0.997, absolute growth with live weight +0.976, daily growth with live weight +0.985, daily growth with absolute growth +0.994. It was observed that these parameters were high positive correlations, 0,88; 0,285; 0,21; 0,002; 0,004, respectively, between the selection traits, compared to those of the pure meat-wool equals.
