THE IMPACT OF VARIOUS FACTORS ON THE MEAT AND FATTENING PERFORMANCE OF PIG HYBRIDS (DXLXLW)

Analysis of interrelation productivity indicators and meat quality pig hybrids (DxLxLW) (n=203) taking into account genotype animals, stress factor feeding complex adaptogens was carried out on the basis data array. The highest correlation were with ADG-CY (P<0.001), ADG-pH24 (P<0.01), BF1-BF2 BF1-pH24 pH45-pH24 WHC-pH45 (P<0.01). study stressful environmental conditions showed their significant effect all parameters taken in analysis: ADG decreased by 7.53% (1005.80 g vs 1087.65 animals without stress; P<0.001), CY 3.12% (73.82% 76.94%; BF1 12.83% (27.40 mm 31.43 mm; P=0.003), BF2 16.39% (17.44 20.86 pH45 3.87% (5.87 6.11; pH24 1.24% (5.51 5.58; P=0.003). At same time, WHC increased 3.73% (74.80% 71.07%; P=0.01). There a (P<0.05) SCD BF1, IGF2 MC4R pH24. Factor group (K) adaptogen had positive growth rates, slaughter yield production quality. By two-factor analysis, studied (dihydroquercetin vitamins E C) value (P=0.005) established. Thus, consideration genetic status animal set measures involving special substances-adaptogens for prevention effects stressors can improve lifetime hybrid pigs.
