Prosyany S. Peculiarities of the animal embryonic growth of different genotype of black and white breed

With growing of Holstein heredity share weight and linear dimensions of uterus, fetus and their organs statistically very likfly increase during research period of calving. It is determined that the change of Holstein fetus genotype had no material effect on chemical composition of fetus, its blood and also mother's blood, inessential effect on chemical composition of roud fetus liquid of calving cows. During research period of calving statistically likely changes of chemical composition of fetus its blood, mother's blood and also round fetus liquid was determined. Considerable dependence of fetus genotype and their gross energy was manifested. Researched immunological factors testify that blood, in a statistically likely quantity, consists of lysozyme and Ig M constantly, inconstantly Ig G and manifestation of bactericidal activity
