摘　　要：文章旨在研究发酵棉籽粕对育肥猪生长性能、肉品质和经济效益的影响。试验将80头生长状况良好的90日龄育肥猪随机分为4组,每组4个重复,每个重复5头。试验组在基础日粮中添加0%、3%、6%和9%的发酵棉籽粕。试验为期100 d(预饲期7 d,正试期93 d)。试验结果表明,使用棉籽粕替代日粮中的豆粕对育肥猪终末体重、平均日增重、平均日采食量和料重比均无显著影响(P> 0.05)。日粮中添加发酵棉籽粕显著降低育肥猪背腰最长肌的pH45min(P <0.05);日粮中添加3%和6%的发酵棉籽粕显著降低育肥猪背腰最长肌的蒸煮损失(P <0.05)。此外,日粮添加发酵棉籽粕对育肥猪背腰最长肌亮度、红度、黄度、pH24 h、剪切力、系水力和滴水损失均无显著影响(P> 0.05)。综上所述,本试验结果表明,尽管发酵棉籽粕对育肥猪生长性能无显著影响,但使用发酵棉籽粕替代日粮中的豆粕能有效降低增重成本,提高毛利润,其中以添加6%发酵棉籽粕处理组经济效益最好。The aim of this study is to investigate the effects of fermented cottonseed meal on the growth performance,meat quality,and economic benefits of fattening pigs.Select 80 healthy and well growing 90 day old finishing pigs and randomly divide them into 4 groups,with 4 replicates in each group,each with 5 pigs.Using 0%,3%,6%,and 9%fermented cottonseed meal instead of soybean meal in the basic diet as the experimental feed.The experiment lasted for 100 days(pre experiment 7 days,formal experiment 93 days).The experimental results showed that using cottonseed meal instead of soybean meal in the diet had no significant effect on the final body weight,average daily gain,average daily feed intake,and feed to weight ratio of finishing pigs(P>0.05).Adding fermented cottonseed meal to the diet significantly reduced the 45 minute pH of the longissimus dorsi muscle in fattening pigs(P<0.05);Adding 3%and 6%fermented cottonseed meal to the diet significantly reduced the cooking loss of the longissimus dorsi muscle in fattening pigs(P<0.05).In addition,the addition of fermented cottonseed meal to the diet did not significantly affect the brightness,redness,yellowness,24-hour pH,shear strength,hydraulic capacity,and drip loss of the longissimus dorsi and lumbar muscles of fattening pigs(P>0.05).In summary,the results of this experiment indicate that although fermented cottonseed meal has no significant impact on the growth performance of fattening pigs,using fermented cottonseed meal instead of soybean meal in the diet can effectively reduce weight gain costs and increase gross profit.
