Abstract
Способ отбора животных казахского белоголового скота по мясной продуктивности стада, включающий дальнейшее повышение живой массы за счет увеличений интенсивности роста и оплаты корма, улучшение мясных форм при сохранении высокой молочности отличающийся тем, что с целью развития и повышения продуктивности стада при сохранении генного набора местного аборигенного казахского скота (72,3%) в казахской белоголовой мясной породе целесообразно использование в селекционно-племенной работе сперму высокоценных быков-производителей, в частности, нового заводского комолого типа «Заволжский» и их продолжателей, учитывая при этом, что отбор животных проводят в несколько приемов: при рождении телят отбирают по происхождению, в 8-иесячном возрасте - по развитию и типичности, при назначении в случку - по интенсивности роста, оплате корма и типу телосложения, а основной отбор проводится при ежегодной бонитировке, животные первого класса и выше, отвечающие требованиям желательного типа, выделяются в племенное ядро (55-60% коров), лучшие коровы для получения от них ремонтных бычков определяются в селекционную группу (8-12% коров племядра), худшие животные выбраковываются (15-25%), ежегодно ремонтные бычки подвергаются двухэтапной оценке.A method of selecting animals of Kazakh white-headed cattle for meat productivity of the herd, including further increasing live weight by increasing the growth rate and paying for feed, improving meat forms while maintaining high milk yield, characterized in that in order to develop and increase the productivity of the herd while maintaining the gene set of local indigenous Kazakh cattle (72.3%) in the Kazakh white-headed meat breed, it is advisable to use sperm of high-value bulls in breeding and breeding, in particular and, the new breeding plant type “Zavolzhsky” and their successors, taking into account that animals are selected in several stages: at birth, calves are selected by origin, at 8 months of age - by development and typicality, when assigned to a mating - by intensity growth, payment of feed and body type, and the main selection is carried out at the annual scoring, animals of the first class and above that meet the requirements of the desired type are allocated to the breeding core (55-60% of cows), I determine the best cows for receiving repair bulls they are in the breeding group (8-12% of the cows of the breeding cows), the worst animals are rejected (15-25%), repair bulls undergo a two-stage assessment annually.
