Abstract
Studies have been performed to determine the relationship between assessment of linear udder traits and lifetime of cows. Experiments were carried out in the herd of breeding farm AF "Mayak" Zolotonosha district of Cherkasy region on the number of cows of Ukrainian Red-and-White (URW) and Black-and-White (UBW) dairy breeds. Estimation of cows firstborn by conformation type was carried out according to the method of linear classification. It was found that cows with higher estimates for condition of udder morphological traits have a longer lifetime compared to animals rated lower score. The difference between cows, rated at one and nine score for trait of the front udder part attachment, was very significant and amounted 939 (URW) and 710 (UBW) days. The difference between the lowest and highest estimates on the basis of height rear udder parts attachment was 687 (URW) and 878 (UBW) days. Animals with an assessment for udder central ligament development below the average (1.4 score) were used from 1675 to 1832 (URW) and from 1535 to 1810 (UBW) days according to estimated breeds. Cows with an assessment of nine score differed by higher lifetime - 2377 days, exceeding cows with the lowest score at 702 days (URW) and 2322 days with reliable excess on 785 days (UBW). The difference between the average lifetime of cows estimated at nine score and with assessment of one score for udder depth was 618 days in cows URW and in UBW - 762 days. It has been proven that cows were used longer in the herd with estimates for front teats position from five to nine score, and a significant decrease in lifetime of cows began with an estimate for this trait from three to one score. Thus, assessment of cows Ukrainian Red-and-White and Black-and-White dairy breeds by the method of linear classification confirmed that the desired development of udder morphological traits was the key to long lifetime cows in modern technological conditions of milk production.
