COMBINATION VARIABILITY OF REPRODUCTIVE FUNCTION OF PIGLETS OF LARGE WHITE BREEDS DIFFERENT METHODS OF BREEDING

Parental organisms that are used for crossbreeding and hybridization should be characterized by a high level of their own productivity and combining ability. The study of combinative ability in the combination of different individuals is necessary to determine the place and influence of parental forms in the patterns of crossing and the formation of specific features. Different inter-breed compatibility was found, which indicates the potential for improvement of the studied herd by reproductive qualities. So, for multifertility, milkness, weight of fish, the weight of all piglets, when weaning and preserving, the best genotypes of VB×L had better results in combining ability.
