Exterior parameters of young cattle of different origin

The aim of research is to study the exterior performance of young Hereford cattle in the Republic of Tuva and to carry out a comparative analysis of the exterior of Hereford young cattle in Tuva and Khakassia. The object of the study was young cattle of the Tuvan population of the Andrianov type of the Hereford breed (at the age of 4-8 months). Exterior assessment of animals was carried out, measurements were taken. After determining the measurements, for a more accurate characterization of the animals, the body indices were calculated. Statistical processing of the data was carried out by the method of variation statistics in the tabular editor Microsoft Excel 2003. As a result of the assessment of measurements of animals, it was found that after the grazing period such measurements as the height at the withers increased by 11.7 cm (12.8 %), the oblique body length by 19.3 cm (19.3 %), chest girth behind the shoulder blades by 16.5 cm (14.1 %), straight body length by 26.8 cm (30.9 %). The autumn stretch index had an advantage over the spring one by 6.5 %. It was found that young cattle of the Hereford breed obtained from imported animals from the pedigree reproducer of OOO Andrianovskiy in the Republic of Khakassia reliably surpasses young animals of the Andrianov type, bred in Khakassia, in oblique body length by 11.5 cm, or 10.7 %. Tuvinian animals surpass young animals in Khakassia by 14 % in elongation index. For the rest of the data, no significant difference was found.
