摘　　要：为进一步了解玉山黑猪种质特性,试验选取2组玉山小黑猪,在相同半放养饲养条件下进行肥育试验,在试验猪只平均体质量分别达到2个不同(A组103kg及B组75kg)级别时按NY/T825-2004方法进行屠宰测定,结果显示宰前体质量、胴体质量、屠宰率、胴体斜长、平均背膘厚度、眼肌面积、瘦肉率、脂率、骨率等指标2组间差异极显著(P<0.01),而肉质性能差异不显著(P>0.05),初步表明:对玉山黑猪体质量在75kg屠宰比100kg以上屠宰更科学。To further understand the germplasm characteristics of Yushan Black Pig,this study selected two groups of Yushan Black Pigs reared under the same semi-stocking conditions for finishing test.When the average weights of the pigs in reached two different （Group A 103 kg and Group B 75 kg） levels,their slaughter was measured according to NY/T825-2004 method.The results showed that the body weight,carcass weight,dressing percentage,carcass plagioclase,backfat thickness,ribeye area,lean rate,fat rate and the rates of other indicators different greatly between the two groups.（P〈 0.01） ,but there was no significant difference in meat performance （P〉 0.05） .This suggests that it is more scientific to slaughter Yushan Black Pigs when weighing 75 kg than when weighing above 100 kg.
