【摘要】 选用杂种仔猪杜×(长×川白)24头,于28±2日龄断奶,以玉米-豆粕型日粮饲喂,进行为期30d的饲养试验,研究日粮中添加0.1%复合酸化剂-酸益SI、0.1%复合酸化剂FD和降低1.5%乳清粉用量对断奶仔猪生产性能、日粮酸和力及肠道大肠杆菌数的影响。结果表明,添加复合酸化剂-酸益(SI)可明显提高仔猪日增重,改善料肉比,大幅度降低腹泻率,降低乳清粉用量与饲料成本。其料肉比、日增重与使用进口产品FD差异不显著(P>0.05)。更多还原

【Abstract】 An experiment was done with 24 crossbred Duroc×(Landrace×Chuanbai) piglets weaned at 28±2d, fed with corn-bean type diet. Studying the effect of the compound organic acid (SI,FD) on the productive performance of weaning piglets, the acidification ability and the amount of coliform bacteria. The result showed that the compound organic acid(SI) could significantly increase average daily gain(ADG), decrease feed/gain (F/G)ratio and diarrhea ratio, and also decrease the cost of feed. The ADG and F/G were not significant difference between SI and import product FD(p>0.05).更多还原
