Productive characteristics of pigs of different breeds

In Russia, the pig breeding industry has been developing successfully in recent years. Their own domestic breeds and intra-breed types of pigs were created. Science and practice have developed breeding and hybridization systems, which made it possible to solve the problem of pork meat shortage in the country in a short time and with a high feed conversion. The aim of the research was to study the genetic correlation of breeding characteristics in pigs of different breeds. The studies were conducted on the livestock of large white breed pigs (KB), Landrace (L) and Duroc (D- Magnus) and their hybrids. As a result of the conducted studies, we have revealed that pigs of different genotypes for different selection characteristics of selection have sufficiently wide limits of fluctuations of the coefficient of variability, which indicates the presence of significant
