Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 100, Issue 2
Abstract
The article has been presented the main economic utility signs of four (Eastern, Central, Tauride and Western) regional types of Ukrainian Red Dairy cattle. The total number of studied animals is 11718 heads, where the share of 68% is of Eastern type. The average milk yields of cows these types of within 4436 kg (West) – 6364 kg (Eastern). The highest values for the protein content of milk were observed in the cows of Tauride, and in terms of the content of fat and living weight – Central type. The fresh cows child for the productive characteristics of high differentiation and technological (the desired form of the udder and the intensity of milk yield). The fluctuation in the age of the disposal of cows is at levels from 2,9 calving in Central type to 3,4 calving in the Tauride, where 94% of the reasons are low productivity and reproductive ability.
