Abstract
Изобретение относитс к животноводству , конкретно к разведению крупного рогатого скота молочных и молочно-м сных пород. Целью изобре п тени вл етс повышение молочной продуктивности у нового поколени животных в зависимости от количестна и расположени участвующих в раз- ведении линий в родословных исследованных 338 коров швицкой породы установлено 12 типов подбора и изучена их молочна продуктивность за первую и вторую лактации. Установлено, что молочна продуктивность коров, полученных разведением с подкреплением наследственности на одну из разводимых линий через отца и отца матери матери, за 305 дней первой лактаци была больше на 8,57%, а за 305 дней второй лактации - на 13,82%. За контроль брали коров 5 полученных разведением с подкреплением наследствеиг- ности на одну из разводимых линий по пр мой мужской линии матери и отца. 1 табл.The invention relates to animal husbandry, specifically to the breeding of dairy and dairy meat breeds. The aim of the invention of the shade is to increase the milk productivity of the new generation of animals, depending on the number and location of the breeding lines in the pedigrees of the studied 338 Schwyz breed cows, 12 types of selection have been established and their milk production for the first and second lactations has been studied. It was established that milk production of cows obtained by breeding with reinforcement of heredity on one of the bred lines through father and mother's father, for 305 days of the first lactation was 8.57% more, and for 305 days of the second lactation - 13.82%. Cows were taken for control by 5 obtained by breeding with reinforcement of the inheritance of one of the breeding lines in the direct male line of the mother and father. 1 tab.
