摘    要:本文研究了在高能精料和低能粗料两种饲养水平下,皖南花猪纯种及其与中约克夏、大约克夏、杜洛克、苏白、长白和荣昌公猪杂交获得的杂种(共112头)肥育至90千克时屠宰的鲜肉品质。结果表明,杂交使皖南花猪的前肢和后躯肉段的含肉率有明显增加,而颈和胸腰肉段的含肉率无明显改进。杂种猪肌肉的失水率高(25.4—32.3%),熟肉率低(65.54—70.84%)。杂交对皖南花猪肌纤维直径和密度影响不大,pH值变化不明显(6.20~6.66)。杂种肌肉蛋白质含量有显著增加,但16种氨基酸总量与纯种相比无明显差异。

关 键 词:皖南花猪  杂交  营养水平  肉质

Abstract:Meat quality of 112 (at 90 kg liveweight) Wannan Spotted pedigree breeds and crossbreeds crossed with medium type Yorkshire, large Yorkshire, Duroc USSR-large white, Landrace, and Rongchang pedigree boars was studied. The experimental pigs were fed at higher energy (HE) and lower energy (LE) feeding levels. The results show that the lean percentages of the shank and rear end of the crossbreeds are increased The carcass lean% of the crossbreeds is increased at LE. As comoare with that of pedigree breeds, the muscle-moistureloss% of crossbreeds is 25.4 to 32.3%, the lower cooked-meat% is 65.54to 70.84%. The effects of crossing on the diameter and density of the muscle fibres, PH, and muscle colour of the pigs are not significant, but the Protein content of crossbreeds is much higher than wannan spotted.
Keywords:Wannan spotted  Cross  Nutriton level  Meat quality
