Abstract

The research results of features of body conformation and composition in cows of central zonal breed type of Ukrainian red dairy breed have been provided. The aim of the research was to define the possibility of chine development in animals by means of selection in the process of breeding this breed type. In agricultural private enterprise “Chumaky” among 70 experimental cows, analogs in age, we have defined the basic conformation measurements and additional indicators: cross-section area of the chest behind the shoulder blades and at the level of the last rib, the conditional volume of the chine and volume-weight number according to the formula: VWN = (V:BV):1000, where VWN – is a volume-weight number, l/kg; V – is a volume of the chine сm3; BW – body weight, kg; 1000 – the coefficient for transformation сm3 in liters.Cows have been divided into three types of a body composition for the deviation from the VWN mean value, which was 0,47 l/kg (n=70). As for low-volume type, with the value of VWN less than 0,44 l/kg were distributed in 20 cows, to mean-volume type, with the VWN in the range from 0,44 to 0,50 l/kg, respectively are 32 animals, and a large-volume type with VWN of 0,51 l/kg or more – 18 cows.Compared with the low-volume type of body composition, cows’ chine of the first two types were much better formed in length respectively: 4,03 cm when P>0,999 and 2,31 cm when P>0,95, on the cross-sectional area of the chest behind the shoulder blades respectively: 223,82 см2 at P>0,99 and 60,78 см2 P<0,95; at the level of the last rib, respectively: 616,76 см2 at P>0,999 and 342,42 см2 at P>0,999, the volume of the chine respectively: 52,09 l when P>0,999 and 25,3 l when P>0,999; with the advantage on volumetric weight coefficient respectively: 0,13 l P>0,999 and 0,06 l when P>0,999. They had a lower eirysomia-leptosomia index respectively 2,83 and 1,06 %, and the shin load index 0,95 and 0,15 %, P<0,95, a higher value of the deep chest index respectively by 2,0 % (P>0,95 and 0,6 %, P<0,95 and conditional volume of the body length, respectively 46158,2 см3 at P>0,99 and 1147,5 at P<0,95. They are characterized by a more expressed body density. When selecting, it is advisable to give preference the animals with large- and mean-volume type of body composition.
