Phenotypic features of black and red dairy cattle populations in the Siberian region

The surveys have identified features of the exterior for 742 breeding cows of black-motley and red steppe breed in the Omsk region conditions. It was found that black motley cows are larger than peers of the red steppe breed are; these differences are 4.7 cm in height at the withers, 8.3 cm - in che...
