首发时间:2004-02-23
摘要: 对含有不同子午岭野猪血缘(25%,50%)或不同杂交组合的野杂种猪与土种猪八眉猪、约克夏猪的肌肉脂肪及脂肪酸进行分析。结果表明野杂种猪体脂性状与野猪血缘及杂交母本有关,与八眉猪杂交的野杂种猪(F1×B)的肌内脂肪含量较高,为4.83%,大理石纹评分为3.30,且野猪血缘比例越高,肌肉脂肪酸不饱和度越高。野杂种猪F1的不饱和脂肪酸含量最高,为49.42%; 野杂种猪中F1×F1亚油酸含量最高,为5.22%,低于八眉猪,高于约克。

Analysis on Fat and Fatty Acid in the Muscle of Pigs with different scrofa (Ziwu Mountainous) Consanguinity
Abstract: The fat performance and the composition of muscle of pigs with different Sus scrofa(from Ziwuling Mountain) consanguinity(25%,50%) and different cross ways were analyzed. The results showed that the marbling grade of F1×B was 3.30, and intramuscular fat was higher, which was 4.83%. The more with Sus scrofa consanguinity, the higher there are unsaturated fatty acid in muscle, and which were correlation with its female parent line. The unsaturated fatty acid of F1、were the highest, which was 49.42%; and linoleic acid of F1×F1 was highest, which was 7.06% , the lowest was Yorkshire.
