摘　　要：本试验选用健康状况良好、无明显疾病的美系长白、大白猪的母猪各10头、公猪各5头、去势公猪各5头分为4组进行为期85 d的饲养试验,研究两品种间生长性能及肉质品质的差异。当试验猪体重达100 kg时试验结束。结果表明,长白母猪、大白母猪、去势公猪与公猪的日增重、日采食量间均差异不显著(P>0.05);长白去势公猪与大白去势公猪的熟肉率、滴水损失(失水率)、压榨水分、初水分及嫩度间差异不显著(P>0.05)。但肌内脂肪间差异显著(P<0.05),大白去势公猪的肌内脂肪高于长白去势公猪。Forty healthy swine （10 sows of landrace and yorkshire each, five breeding boar of landrace and yorkshire each, 5 geldedox pig of landrace and yorkshire each） were divided into four groups with ten pigs per group.In order to investigate the differences of growth performance and meat quality between the two varieties, a feeding experiment of 85 days was carried out. When the weight of pig was up to 100 kg, the test ended. The results indicated that the daily gain and feed intake were not significant among each group （P 〉 0.05）. In cooking percentage, water loss, the squeeze water, original moisture and shear force, there were no significance between geldedox landrace and yorkshire （P 〉 0.05）, but intramuscular fat was significant different （P 〈 0.05）. Intramuscular fat of geldedox yorkshire was higher than that of geldedox landrace.
