【摘要】：在相同饲养管理条件下,利用杜洛克、巴克夏和苏太猪分别与豫南黑猪开展杂交试验,以纯种豫南黑猪为对照,分析三种杂交F1代猪肉常规肉质性状、营养成分、氨基酸组成、必需氨基酸评分及脂肪酸组成情况。结果表明:豫南黑猪纯种繁育后代的肌内脂肪、5种鲜味氨基酸和8种必需氨基酸的含量均高于其它杂交组合,但差异不显著(P0.05);豫南黑猪及其三种杂交组合F1代常规肉质指标表现优良,其中与杜洛克杂交显著增大了眼肌面积(P0.05),与巴克夏杂交显著提高了熟肉率(P0.05),与苏太猪杂交显著提高了肌肉嫩度(P0.05);不同杂交组合对猪肉中氨基酸的含量影响不显著(P0.05)。在四个杂交群体的背最长肌中,5种饱和脂肪酸含量各杂交组合间差异不显著(P0.05),但与苏太猪杂交后代6种不饱和脂肪酸含量显著高于其它杂交组合(P0.05)。豫南黑猪肉质优良,其鲜味氨基酸和不饱和脂肪酸含量丰富,与苏太猪杂交后的肉质综合效果好,与杜洛克和巴克夏杂交后的肉质性状突出,为豫南黑猪进一步开发利用提供一定的理论依据和技术支持。
[Abstract]:Under the same feeding and management conditions, using Duroc, Baxia and Sutai pigs to carry out crossbreeding experiments with black pigs in southern Henan, the conventional meat traits, nutritional components and amino acid composition of three F1 generation crossbred pigs were analyzed using purebred black pigs as control. Essential amino acid score and fatty acid composition. The results showed that the contents of 5 delicious amino acids and 8 essential amino acids of pure breed progenies of black pigs in southern Henan Province were higher than those of other cross combinations. However, the difference was not significant (P 0.05), and the normal meat quality index of F _ 1 generation of black pigs and their three cross combinations in southern Henan showed good performance. The cross with Duroc significantly increased the eye muscle area (P0.05), the cooked meat rate (P0.05) and the muscle tenderness (P0.05) of Sutai pig, and the different cross combinations had no significant effect on the content of amino acids in pork. There was no significant difference in the content of saturated fatty acids among the five hybrids in the longissimus dorsi among the four cross populations, but the content of the unsaturated fatty acids in the six hybrids with Sutai pig was significantly higher than that of the other crosses. The meat quality of black pigs in southern Henan Province is excellent, the contents of fresh amino acids and unsaturated fatty acids are rich, the meat quality comprehensive effect after crossing with Sutai pig is good, and the meat quality character after crossing with Duroc and Barkxia is outstanding. To provide some theoretical basis and technical support for the further development and utilization of black pigs in southern Henan.
