摘要: 为研究杜洛克猪(D)、长白猪(L)、大白猪(Y)和梅山猪(M)组合的配套杂交商品猪(DLYM)的胴体品质和肉质特性,本试验对其屠宰性能和肉质性状进行了系统测定。结果表明,DLYM瘦肉率为53.97%±6.82%;平均背膘厚为3.32 cm±0.52 cm;眼肌面积为46.01 cm2±3.14 cm2;屠宰后45 min的pH1为6.69±0.52;熟化24 h后pH2为5.68±0.74;屠宰后45 min光反射值为41.59±4.24;屠宰后24 h光反射值为49.42±5.61;大理石纹为2.33±0.07;滴水损失为3.58%±0.25%;剪切力为4.82 kg±1.36 kg。综合测定结果表明,DLYM杂交商品猪瘦肉率适中,在肉质性状和胴体品质方面表现突出,非常适应西南地区对优质猪肉的需求,达到了胴体与肉质平衡发展的需求,是一种简洁高效的优质杂交组合模式。

Abstract: To study the carcass performance and meat quality of the hybrid fatten pig(DLYM) combined with Duroc(D),Landrace(L),Yorkshire(Y) and Meishan(M). We had systematically measured the carcass characters and meat quality. The results indicated that DLYM hybrid fatten pig had a good carcass characteristics and meat quality. Such as the percentage of lean meat was 53.97%±6.82%; mean of the thickness of backfat was 3.32 cm±0.52 cm; the area of longissimus dorsi was 46.01 cm2±3.14 cm2; pH1 at 45 min postmortem was 6.69±0.52; pH2 at 24 h postmortem was 5.68±0.74; the meat lightness at 45 min postmortem was 41.59±4.20; the meat lightness at 24 h postmortem was 49.42±5.61; marbling was 2.33±0.07; drop loss was 3.58%±0.25%; shear force was 4.82 kg±1.36 kg. In conclusion, DLYM hybrid fatten pig had a appropriate lean meat percentage and an outstanding carcass and meat quality characters, which was special adapt to the demand for high quality pork in southwest China and reached the balanced development between carcass characters and meat quality. It is a concise and efficient type of high-quality hybrid combination mode.
