ASSESSMENT EXTERIOR SIGNS IN PREDICTING MEAT PRODUCTIVITY OF YOUNG CATTLE OF SIMMENTAL BREED AND SIMMENTAL-BISON IN YAKUTIA

The article presents the results of studieson the dynamics of live weight, exterior measurements and body compositionindices in purebred Simmental and crossbred animals. It is established that thehybrids obtained as a result of crossing of cows of Simmental breed with forestbison in all age periods surpassed the Simmental analogs on live weight andintensity of growth. The dynamics of the exterior of the measurements had nostatistically significant intergroup differences, except in the indices ofmassiveness and bytosti from the crossbred calves in 5 and 18 months of age,the superiority in 5месячном the age was on the index of bytosti – of 8,85 %(P ≥ 0,99), the index of massiveness and 5,5 % (P ≥ 0,95).In 18 months – 8,3–8,9 % and 6,7–8,2 %, respectively (p ≥ 0,95).The study of the relationship of live weight with the main linear measurementsrevealed a positive, straightforward, sufficiently high correlation. Thus, thecorrelation coefficient between live weight at 24 months and height at withersat 9 months of age was 0,909 in bulls, 0,998 in heifers, 0,937 and 0,966respectively in Simmental-bison. At the same time, for Simmental bisonsignificantly high correlation coefficients were found between live weight andchest girth: in bulls – 0,949, in heifers – 0,909 (p ≥ 0,99), chestdepth 0,816 and 0,676, as well as oblique body length – 0,885 and 0,951,respectively (P ≥ 0,99). In General, the material obtained as, aresult of mathematical processing indicates the possibility of predicting themeat productivity of experimental animals on the main exterior measurements.
