摘要: 为了解闭锁繁殖群体中藏猪的胴体和肉质性能在不同世代间的变化。对一个闭锁繁殖藏猪群内的第1世代和第4,5世代的藏猪进行屠宰并对胴体性能和肉质性能进行测定。通过主成分分析和聚类分析发现第1世代藏猪与第4,5世代藏猪的胴体性能没有明显差异。对3个世代的肉质性能测定发现,第1世代和4,5世代pH值和L值没有显著差异(P >0.05),而第1世代藏猪具有较好的熟肉率(P <0.05),第4,5世代藏猪具有更好的嫩度和韧性(P <0.05),通过主成分分析和聚类分析发现肉质性能在第1世代和第4,5世代间存在差异。在对3个世代藏猪肌肉中氨基酸和脂肪酸测定发现,肌肉中氨基酸和脂肪酸组成结构在第1世代和第4,5世代间也存在差异。结果说明,闭锁繁殖到第4代时,藏猪的胴体性能没有发生改变而肉质性能部分发生改变。总体结果表明,经历了长期的放牧饲养后,藏猪已经适应了这种闭锁繁殖的粗放饲养模式,群体总体保持相对稳定。

Abstract: In order to study the effects of closed-flock reproduction on carcass performance,meat quality of Tibetan pigs in different generations. Three generations of Tibetan pigs were slaughtered and their carcass and meat quality were measured. The results of principal component analysis and cluster analysis showed that the carcass performance of first-generation (F1) Tibetan pigs was not different from fourth-generation (F4) and fifth-generation (F5). The pH and L value were not significant difference in different generations (P >0.05). However,F1 had a higher cooked meat percentage (P <0.05),F4 and F5 had a better tenderness and toughness (P <0.05). There were significant differences in meat quality,amino acid structure and fatty acid structure between F1 and F4,F5. The final analysis showed that the meat quality of Tibetan pigs changed after F4 of closed-flock reproduction. Therefore,after long-term grazing,the carcass performance and meat quality of Tibetan pigs are relatively stable.
