BREEDING AND GENETIC PARAMETERS OF REPRODUCTIVE TRAITS OF PIGS OF MATERNAL BREEDS
Abstract
Selection parameters of reproductive traits of sows of maternal breeds are determined: so multiple pregnancy by breeds was: Belarusian large white - 11-12 piglets, the Belarusian black-motley breed - 10-11, the Belarusian plant type of Yorkshire breed pigs - pigs 11,5-12,5 piglets. It was determined that multiple pregnancy of sows carrying in the genome preferred genotype BB of ESR gene averagely by breeds made: Belarusian large white breed - 11,48 piglets, Belarusian black-motley breed - 11,0, Belarusian plant type of Yorkshire breed - 11,9 piglets.It is determined that sows of maternal breeds with a preferred genotype BB of ESR gene in genome had multiple pregnancy indicators corresponding to the data of selection parameters due to genetic potential, that indicates possibility of improving reproduction traits by methods of marker-dependent selection.
