External characteristics adults cows of ukrainian black and white dairy breed

The results of the evaluation exterior of the animals Ukrainian black and white dairy cattle in the western region of Ukraine. Studies conducted on animals Ukrainian black and white dairy cattle in the «Milk River» farm in the Sokal and Brody offices breeding reproducers «Breeder» Lviv region and plant breeding «Yamnytsya» Ivano-Frankivsk region. Exterior animals was assessed by measurement of body articles. By value measurements calculated indices of body structure cows. Weight-size factor determined by the formula D.T. Vinnychuka and P.N. Merezhko. The results of research were treated by variational statistics G.F. Lakin. Adults cows of Ukrainian black and white dairy breed for exterior fit the type of dairy animals. Measurements body cows are: height at the withers – 135,6–136,5 depth of chest – 75,1–77,1 width chest – 46,2–48,6, chest girth for by shoulder – 197,0–201,2, oblique body length – 161,4–163,6 width in clubs – 54,5–57,2 girth metacarpus – 19,1–19,5 cm. By oblique trunk length and girth metacarpus, and in the «Milk River» farm Sokal offices and plant breeding «Yamnytsya» also for girth at breast for by blades are dominated by target parameters for the desired type of animal. By other body measurements investigated cows do not reach target parameters for the desired type of animal. Further breeding work with this array of animals should be directed to increase the linear dimensions of the body, with particular attention paid to the width of the chest. Indices body structure cows in farms of different characteristic type of dairy animals. Surround dimensions of the animals constituted 494,9–501,4 cm weight-size factor – 1,08–1,15. In cows of all farms the ratio of live weight and measurements body was typical for relatively stretched animals.
