| 摘 要： | 姜曲海猪瘦肉型品系的选育以杜枫姜猪 (杜洛克猪、太湖猪与姜曲海猪杂交而成 )为基础亲本。试验结果表明 :杜枫姜猪与杜姜猪、枫姜猪、姜曲海猪相比 ,平均日增重、饲料转化率、后腿比例和胴体瘦肉率均有所提高 ,而胴体平均背膘厚、骨皮比例和脂肪比例均有所下降 ,肌纤维直径变粗 ,肌内脂肪含量适宜 ,具备了新品系选育的种质条件 |
| 关 键 词： | 猪 日增重 瘦肉率 生化指标 肌纤维直径 |

| Abstract: | DFJ (Duroc×Fengjing×Jiangquhai) was the base parents of breeding new Jiangquhai meat type line. The hybrids of D × F × J, F × J, D × J, J × J were studied for growth performance, blood biochemical values and muscle histologic. Compared with D× J, F × J and J × J hybrids, the average daily gain, feed conversion efficiency, ratio of carcass to ham, lean meat percentage and muscle fiber diameter was superior, the average back-fat depth, bones and skin percentage and fat percentage was lower, the crude fat percentage is fit, in D× F × J hybrid. These values suggested that the DFJ was fit to be basic parents for breeding new Jiangquhai meat type line. |
| Keywords: | swine daily gain lean meat percentage biochemical values muscle fiber diameter |
