摘　　要：为评价巴克夏与鄂通两头乌杂交组合的效果,以70头巴鄂杂交猪(巴克夏为父本,鄂通两头乌为母本)为研究对象,对其胴体性状、肉质性状相关指标进行测定,并对肉质性状和胴体性状进行相关性分析。结果显示:巴鄂杂交猪宰前活重为(109.10±11.01)kg,屠宰率为74.28%±1.99%,眼肌面积为(31.40±3.57)cm^2,背膘厚为(31.65±5.66)mm,皮厚为(3.32±0.74)mm,肉色评分1为(3.80±0.77)分,肌内脂肪含量为1.94%±0.54%,48 h滴水损失为2.07%±6.18%。背最长肌中检测到13种脂肪酸,其中饱和脂肪酸含量为31.92%±7.68%,不饱和脂肪酸含量为68.08%±6.18%,背最长肌中检测到肌苷酸含量为(3.71±0.42)mg/g。相关性分析显示:巴鄂杂交猪内脂率与背膘厚极显著正相关(P<0.01,r=0.69),肌内脂肪含量与肉色评分1极显著负相关(P<0.01,r=-0.37),肌苷酸含量与胴体直长极显著正相关(P<0.01,r=0.4)。以上结果表明:巴鄂杂交猪的屠宰性能良好,平均背膘厚和皮厚适中,肌肉颜色鲜亮,系水力好,不饱和脂肪酸含量和肌苷酸含量较高,获得了良好的杂交效果。In order to evaluate the breeding effect of the hybrid combination of Barkshire and Etong Two-End-Black pig,the carcass and meat quality traits were measured in 70 Bae hybrid pigs(Barkshire×Etong Two-End-Black).The results showed that the body weight of Bae hybrid pigs was(109.10±11.01)kg,the slaughter percentage was 74.28%±1.99%,the loin eye area was(31.40±3.57)cm^2,the backfat thickness was(31.65±5.66)mm,the skin thickness was(3.32±0.74)mm,the flesh color score 1 was 3.80±0.77,the intramuscular fat content was 1.94%±0.54%,and the drip loss at 48 h after slaughter was 2.07%±0.76%.Thirteen fatty acids were detected in the dorsal longest muscle,of which the saturated fatty acid content was 31.92%±7.68%,the unsaturated fatty acid content was 68.08%±6.18%,and the inosine monophosphate content detected in the longest muscle of the back was(3.71±0.42)mg/g.Correlation analysis showed that the fat percentage of the Bae hybrid pigs was significantly positively correlated with the backfat thickness(P<0.01,r=0.69),the intramuscular fat content was significantly negatively correlated with the meat color score 1(P<0.01,r=-0.37),and the inosine monophosphate content was significantly positively correlated with the carcass length(P<0.01,r=0.4).To sum up,the results of this study showed that the slaughter performance of Bae hybrid pigs was great,the backfat thickness and skin thickness were moderate,the muscle color was bright,the line was good in hydraulic power,and the hybridization effect obtained was great.
