THE BIOCHEMICAL INDICATORS OF BLOOD SERUM AND THEIR RELATIONSHIP WITH FATTENING AND MEAT QUALITIES OF YOUNG SWINE OF DIFFERENT INBREED DIFFERENTIATION ACCORDING TO THE SAZER-FREDIN INDEX

The article presents the results of studies of protein metabolism and their relationship with fattening and meat qualities of young pigs of large white breeds of different interbreed differentiation according to the index of A. Sazer - H. Fredin. It was found that the biochemical parameters of the serum of young pigs of the experimental group correspond to the physiological norm of clinically healthy animals. Taking into account the interbreed differentiation of young pigs of the large white breed according to the index of A. Sazer - H. Fredin, it was found that the animals of group II outperformed peers of I on average daily live weight gain during control fattening, age of 100 kg live weight, fat thickness at 6-7 thoracic vertebrae, the length of the chilled carcass, the length of the bacon half of the chilled half-carcass on average by 4.03%. The pairwise correlation coefficient between the biochemical parameters of blood serum, fattening, and meat qualities of young pigs of large white breeds range from -0.533 to +0.528.
