【摘要】 研究设计了铁骨猪×铁骨猪(铁骨)、巴克夏猪×铁骨猪(巴铁)、杜洛克猪×铁骨猪(杜铁)等3个品种组合,并通过胴体、肉质共计54项指标测定来比较它们的优劣,旨在测定铁骨猪和巴克夏、杜洛克的杂交性能,筛选出较为理想的杂交组合。结果表明,瘦肉率、6~7肋间皮厚、眼肌面积、剪切力、油酸、亚油酸等13个指标组间存在显著或极显著差异(P<0.05或P<0.01),其中杜铁、巴铁的瘦肉率极显著高于铁骨猪(P<0.01),巴铁的剪切力显著低于铁骨猪和杜铁猪(P<0.05),铁骨猪的多不饱和脂肪酸显著高于巴铁和杜铁(P<0.05)。所有试验猪均表现出了良好的胴体性能和肉品质。更多还原

【Abstract】 In order to test the cross performance of Berkshire, Duroc and Pushi Tiegu Pig and pick out the valuable cross combination, three combinations were designed in this study, namely Tiegu Pig ×Tiegu Pig(TG),Berkshire ×Tiegu Pig(BT), Duroc ×Tiegu Pig(DT), and 54 indicators of carcass and meat quality were used to compare pros and cons of the three combinations. The results show that 13 indicators(lean rate, thick skin of the6-7 rib, loin muscle area, shear force, oleic acid, linoleic acid and so on) had the difference between groups reached the significant or highly significant level(P<0.05 or P<0.01). The lean rate of BT and DT were highly significantly higher than TT(P<0.01), the shear force of BT was significantly lower than DT and TT(P<0.05), the polyunsaturated fatty acids of TT was significantly higher than DT and BT(P<0.05). All pigs showed good carcass performance and meat quality.更多还原
