| 摘 要： | 选用〔(65±2)d〕的杜×长×大三元杂交阉公猪进行生长期(65～130 d)和育肥期(131～162 d)两个阶段试验,通过在猪生长育肥期日粮中以不同比例的普通棉粕和发酵棉粕替代豆粕,探讨在猪日粮中普通棉粕和发酵棉粕适宜的添加用量。生长期供试仔猪随机分为5个组,每个组10头。分别饲喂含豆粕日粮(对照组),5%或10%普通棉粕替代豆粕日粮(试验Ⅰ组和Ⅱ组),10%或15%发酵棉粕替代豆粕日粮(试验Ⅲ组和Ⅳ组)。在育肥期,对照组继续饲喂豆粕日粮外,试验Ⅰ组至Ⅳ组各随机分为两个处理组,其中一组继续使用棉粕日粮,另外一组改用豆粕日粮。试验结果显示,与对照组相比,普通棉粕替代豆粕的比例达到5%时,猪的日增重有下降趋势;达10%时可显著降低猪的日增重和饲料报酬(P0.05);发酵棉粕替代豆粕的比例达到15%时对猪生长育肥期的生长性能尚无显著不良影响(P0.05),可以降低单位增重饲料成本;生长期使用棉粕而在育肥期停用棉粕与全期使用棉粕相比,对猪在育肥期的生长有增加趋势,并且具有单位增重饲料成本低的优势。

| Abstract: | The present study was set to discuss appropriate number of common cottonseed meal and fermented cottonseed meal added in the diet of fifty crossbred hog barrows at 65 days of age（65-130 d） and finishing period（131-162 d）.The pigs in growth period（65-130 d） were randomly divided into five groups,10 head of pig for each.Control group were fed with the maize-soybean meal diet,5%,10% of the common cottonseed meal instead of soybean meal diet（group Ⅰ and group Ⅱ）,10%,15% fermented cottonseed meal instead of soybean meal diet（group Ⅲ and Ⅳ）.The control group continues to be fed with soybean meal diet,the experimental group Ⅰ-Ⅳ groups were randomly divided into two control groups,one of which continued to be fed with cottonseed meal diet,another group of which was fed with soybean meal diet.The results showed that when 5% cottonseed meal replaced soybean meal,daily weight gain of pigs were decreased compared with the control group;When 10% cottonseed meal replaced soybean meal,the daily weight gain and feed efficiency（P0.05） were reduced;However when the pigs were fed with 15% fermented cottonseed meal instead of soybean meal in diet,there were no effect on the growing performance of pigs and the unit cost of feed could be reduced at finishing period.The experiment was conducted that feeding with cottonseed meal in growing stage and ceasing to feed with it in finishing stage were compared with that in the whole stage,the result showed that feeding with cottonseed meal can accelerate the growth of the pigs and reduce the weight gain with units of feed costs. |
