Selection and genetic parameters of conformation traits of new interbreed type of cattle "Ertys"

Article provides results of researches which carried out for studying types of cattle conformation in new interbreed type Ertys in Simmental breed. According to comparison of average sizes for 19 characteristics of conformation and coefficient of variation is determined that animals have body composition related to dual-purpose cattle. They have approximately similar high and their pelvis tilt (angle) is located higher little bit than in other cattle types. Also they characterized by medium size of udder, lacking udder furrow, standard high and width of back rump udder, optimal size of nipples. But we observe that the placement of front teats close together. Heritability coefficients of exterior traits: on medium level. It was determined that performances of growth, pelvis tilt and its width, lengths of pile of sheaves arranged crosswise, deep of udder floor, front teats placement, back legs position in a less degree are exposed to influence of paratypic factors. It was established that there are correlation relationship between milk yield and width of back rump udder.
