摘要： 为了研究饲喂酶制剂青贮的杂交狼尾草对公猪和母猪生长性能及肉品质的影响，笔者开展了4种杂交狼尾草青贮处理，组Ⅰ为杂交狼尾草添加麦麸，组Ⅱ为杂交狼尾草添加麦麸和纤维素酶，组Ⅲ为杂交狼尾草添加麦麸和纤维素菌液，组Ⅳ为杂交狼尾草添加麦麸和乳酸菌。将4种方式处理的杂交狼尾草添加至基础日粮中，对照组只饲喂基础日粮，75天后称重计算猪的日增重，将猪屠宰后分别测定宰后1 h和宰后24 h的pH和肉色，以及宰后24 h的肌肉大理石纹和系水力。结果表明：Ⅰ-Ⅳ处理组和CK组的公猪日增重分别比母猪高出7.8%、6.7%、12.2%、1.1%和10.7%；Ⅰ-Ⅳ处理组公猪和母猪平均日增重分别比CK组提高3.31%和5.58%；处理组公猪和母猪的pH1、pH24和肌肉干物质含量与对照组差异不显著(P>0.05)，但饲喂杂交狼尾草后公猪的肌肉干物质含量会适当降低，母猪的肌肉干物质含量、肉色1、肉色24和大理石纹值均略有提高。同时肉猪特别是公猪的系水力也会提高，猪肉品质得到改善。这说明饲喂酶制剂青贮的杂交狼尾草既能提高公猪和母猪的日增重，还能改善猪肉品质，这为开发酶制剂青贮的杂交狼尾草猪饲料奠定基础。

Abstract: In order to study the effect of forages silaged by enzymes preparation on hog growth performance and pork quality, four silage forage feeding treatment groups were used. Hogs in groupⅠ, Ⅱ, Ⅲ, Ⅳ were fed by basal diet with hybrid Pennisetum adding wheat bran, hybrid Pennisetum adding wheat bran and cellulase, hybrid Pennisetum adding wheat bran and cellulose microorganisms broth and hybrid Pennisetum adding wheat bran and lactobacillus, respectively. Hogs in the control-group (CK) were only fed by the basal diet. The average daily gain (ADG) was calculated after 75 days. Pork pH and color were determined respectively one hour and 24 hours after slaughtered. Muscle marble and water holding capacity (WHC) were also determined 24 hours after slaughtered. The results showed that compared with the sows, daily gains of the boars in the four treatment groups and the CK group increased by 7.8%, 6.7%, 12.2%, 1.1% and 10.7%, respectively. Compared with the control group, ADG of the boars and sows in the four treatment groups increased by 3.31% and 5.58%, respectively. There was no statistical difference at pH1, pH24 and pork dry weight between the treatment group and the control group (P>0.05). Pork dry weight of the boars slightly decreased. But pork dry weight, color and marble value of the sows increased. Meanwhile water holding capacity especially in the boars increased. All the findings clarified that the forages silaged by enzymes preparation could be used not only to improve the average daily gain but also the pork quality. It offered good foundation for exploring of forages silaged by enzymes preparation.
