BREEDING AND GENETIC PARAMETERS OF FEEDING AND MEAT AND FAT TRAITS OF PUREBRED YOUNG PIGS

Abstract

In the course of the research, correlations between fattening and meat and fat traits of young pigs reared in Belarus were studied. The correlation coefficients between fattening and meat traits were generally small and amounted to 0.15 to 0.30 for animals of Belarusian breeds and 0.19 to 0.33 for imported animals. Analysis of correlation coefficients between measurements of carcass and its separate cuts also showed low correlation. Thus, between the carcass length and backfat thickness, the overwhelming majority of the domestic (except for the Belarusian black-and-white breed) breed and import selection showed a slight negative correlation, which ranged from -0.18 to -0.23. A relatively low positive correlation was determined between the carcass length and indicators of hind quarter weight and loin area, which made in the first case from 0.13 to 0.30, and from 0.16 to 0.37 in the second case.
