          摘要:

          為評價巴克夏與鄂通兩頭烏雜交組合的效果,以70頭巴鄂雜交豬(巴克夏為父本,鄂通兩頭烏為母本)為研究對象,對其胴體性狀、肉質性狀相關指標進行測定,并對肉質性狀和胴體性狀進行相關性分析。結果顯示:巴鄂雜交豬宰前活重為(109.10±11.01) kg,屠宰率為74.28%±1.99%,眼肌面積為(31.40±3.57) cm2,背膘厚為(31.65±5.66) mm,皮厚為(3.32±0.74) mm,肉色評分1為(3.80±0.77)分,48 h滴水損失為2.07%±0.76%。背最長肌中檢測到13種脂肪酸,其中飽和脂肪酸含量為31.92%±7.68%,不飽和脂肪酸含量為68.08%±6.18%,背最長肌中檢測到肌苷酸含量為(3.71±0.42) mg/g。相關性分析顯示:巴鄂雜交豬內脂率與背膘厚極顯著正相關(P<0.01,r=0.69),肌苷酸含量與胴體直長極顯著正相關(P<0.01,r=0.4)。以上結果表明:巴鄂雜交豬的屠宰性能良好,平均背膘厚和皮厚適中,肌肉顏色鮮亮,系水力好,不飽和脂肪酸含量和肌苷酸含量較高,獲得了良好的雜交效果。

          Abstract:

          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) cm2,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,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),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.
