摘要
试验选用9窝83头断奶仔猪为试验对象(平均断奶日龄为28d),随机分成3组,分别饲喂在基础日粮中添加0,1%,2%柠檬酸的饲粮,探讨饲喂不同pH值的日粮对断奶仔猪腹泻程度及平均个体增重的影响。试验结果表明,饲喂pH值低的日粮显著降低了断奶仔猪的腹泻率并提高了仔猪的日增重(P<0.05),以添加2%柠檬酸组效果最好。
Eighty-three weanling piglets （at the age of 28 ＋1 days） were randomly divided into 3 groups, and were fed with basal diet supplemented with 0, 1%, 2% citric acid, respectively to study the effects of differ ent levels of pH in basal diet on diarrhea and average weight gain of weanling piglets, The result showed that low pH in basal diet Significantly decreased the diarrhoea frequency and increased average-day-gain of weanling piglets（P〈0.05）, diet adding 2 % citric acid had the best effect.
