二花脸、皮特兰猪肌肉品质和能量代谢的比较

In the present study, Erhuanlian exerted excellent meat quality traits compared with Pietrain, indicated by significantly lower pH45min, pH24h (p < 0.01), better meat color and water holding capacity (all p < 0.05). Significant differences regarding metabolic characteristics between breeds were also detected. Erhualian had significantly higher CK, LDH and lower AMPK activities (all p < 0.01)in comparison with Pietrain, but another key factor in muscle energy metabolism, PGC-1α, its transcriptions didn’t shown significance between breeds. Results suggested that distinct metabolic pattern might make a great contribution to breed specific meat quality.
