摘　　要：随机选择65日龄、均重25.0kg的杜长大生长猪160头,随机分为4组,研究虫草真菌液体发酵中草药培养基对生长肥育猪生产性能和胴体品质的影响。结果表明,日粮中添加100mg/kg、200mg/kg和300mg/kg虫草真菌液体发酵中草药培养基后,与对照组相比,生长肥育猪的日增重分别提高了7.64%、9.23%和11.19%(P≤0.05或P≤0.01),采食量分别提高了2.72%、1.37%和2.10%(P≥0.05),料肉比分别降低了4.58%、7.19%和8.17%(P≤0.05或P≤0.01),屠宰率分别提高了2.95%、5.66%和8.53%(P≤0.05或P≥0.05),瘦肉率分别提高了0.60%、2.67%和6.64%(P≥0.05),背膘厚分别降低了4.29%、5.71%和8.29%(P≤0.05或P≥0.05)。结论:虫草真菌液体发酵中草药培养基可明显提高生长猪生产性能,改善育肥猪胴体品质。The study was conducted to characterize the effects of cordyceps sinensis liquid fermentation Chinese herbal medicine culture medium on performance and pork quality in finishing pigs. A total of 160 in 65-day-old finishing piglets （Duroc × Landrace × Large） with average body weight of 25kg were randomly allotted into the 4 treatments. The The results were as follows： compared with control group, the diet adding （100mg/kg, 200mg/kg, 300mg/kg） cordyceps sinensis liquid fermentation Chinese herbal medicine culture medium, daily gain was raised 7.64%, 9.23% and 11.19%（P≤0.05 or P≤0.01）, feed intake was raised 2.72%, 1.37%and 2.10%（P≥0.05）, feed gain ratio was decreased 4.58%, 7.19%.and 8.17% （P≤0.05 or P≤0.01）, slaughter rate was raised 2.95%, 5.66% and 8.53%（P≤0.05 or P≥0.05）, lean percentage was raised 0.60%, 2.67% and 6.64% （P≥0.05）, backfat thickness was reduced 4.29%, 5.71% and 8.29%（P≤0.05 or P≥0.05）, respectively. The results indicated that cordyceps sinensis liquid fermentation Chinese herbal medicine culture medium may increase performance obviously and improve carcass quality.
