摘要
选不同比例梅山猪血缘 (梅山猪血缘比例为 0 ,1/ 8,1/ 4,3/ 8,1/ 2 ,1)的杂种仔猪 6 8头 ,采用单因子试验设计 ,在同一营养水平 (DE :前期 14 2 1MJ/kg ,后期 13 79MJ/kg ;CP :15 % ,13 % ;Lys:0 75 % ,0 6 5 % )下 ,研究不同比例梅山猪血缘对不同体重阶段生长育肥猪肉质及肌纤维组织学特性的影响。结果表明 :梅山及其杂种猪与杜大猪相比 ,肉色好 (P <0 0 5 ) ,pH值正常 (P <0 0 1) ,肌内脂肪含量高 (P <0 0 1) ,分布均匀 ,系水力高 (P <0 0 5 ) ,无异常肉发生 ,其它常规化学成分分析差异不显著 (P >0 0 5 ) ;肌纤维直径随梅山猪血缘比例增加逐渐变细 。
Sixty eight crossbred pigs with 0, 1/8, 1/4, 3/8, 1/2 different Meishan consanguinity were employed to investigate the effect of different consanguinity on meat quality and muscle fiber character of different finishing stages. The results show that longissimus muscle color, pH, marbling scores, water holding capacity of Meishan and crossbred pigs with Meishan consanguinity are significantly higher (P<0 01) than those of Duroc×Large white. Muscle fiber diameters of different stages of finishing pigs decrease gradually as Meishan consanguinity increases (P<0 01) and enlarges as body weight increases (P<0 05).
