Abstract

The results of the study of constitutional features cows firstborn Ukrainian Red dairy cattle and their relation to milk production and reproductive ability. Established that the first fruits of the type conventionally dense constitution metrics overall body measurements significantly superior to peers with relatively loose type. The difference in height at the withers, deep chest, oblique body length, width and maklakah nominal volume of the body was, respectively, 5,3 cm (P>0,999), 8,7 cm (P>0,999), 3,6 cm (P>0,95), 3,7 cm (P>0,999) and 115,013.4 cm3 (P>0,999). Only in terms of body density advantages are relatively loose type animals compared to conventionally constitution dense type of 0,26 g/cm3 (P>0,999).

Firstborn relatively thick type Constitution significantly superior to analogue relatively loose all types of quantitative traits of milk production, namely for yields, milk fat and milk protein respectively 448 kg (for P>0,999), 13,9 kg (for R>0,99) and 16,4 kg (with P>0,999). In terms of the quality of the milk no significant difference between the experimental group of animals is not installed. Firstborn relatively loose type for the constitution yields slightly higher than standard Ukrainian Red dairy breed (3100 kg of milk for the first lactation).

Firstborn different types of constitution marked satisfactory reproductive ability, with high fertility, only longer period was mizhotelnyy individuals of relatively dense compared to peers type conventionally loose type at 12 days (P>0,95).
