PROTEIN METABOLISM INDICATORS AND THEIR CORRELATION WITH FATTENING AND MEAT QUALITIES OF YOUNG PIGS OF DIFFERENT INTENSITY OF FORMATION IN EARLY ONTOGENESIS

The article presents the results of study biochemical indicators blood serum and their relationship with fattening meat qualities young pigs large white breed, as well calculation level correlations between signs economic efficiency use in conditions industrial complex. Studies show that breed correspond to physiological norm clinically healthy animals, namely: total protein content is 83.46 g/l, urea 5.15 mmol/l, nitrogen 10.14 mg %; coefficient variation specified quantitative features interior ranges from 4.85 14.99 %. By age reaching a live weight 100 kg, animals sample (N=42) exceed minimum requirements elite class by 6.57, thickness lard at 6-7 thoracic vertebrae - 28.62, length chilled carcass 3.72 Taking into account intrabreed differentiation according "intensity formation" index, it was established II experimental group (∆t=0.715-1.011) prevailed over peers same I (∆t=1.076-1.356) terms average daily gain, kg fat an 3.61%.
