摘要 本研究将20窝平均个体重(6.07±0.63)kg的21日龄断奶仔猪随机分为对照组和试验组,每组10个重复,每窝为一个重复(每窝平均9.8头)。对照组饲喂固态料,试验组在开始第1~2天饲喂液态料,第3~5天过渡,第6~7天饲喂固态料,试验期为7 d。结果表明:对照组和试验组的仔猪固形物总采食量分别为107、160 g/d·头,试验组比对照组增加了49.5%(P<0.01);平均日增重分别为-22.86、12.86g/d·头,试验组比对照组多增重35.72 g/d·头,增重效果极显著(P<0.01)。说明发酵液态乳猪料可有效缓减仔猪的断奶应激。 This experiment was conducted to evaluate the effects of fermentation liquid feed on growth performance of weaned piglets.A total of 20 litters weaned piglets with average weight(6.07±0.63)kg(aged in 21 days) were randomly divided into 2 groups with 10 replicates of 9.8 each.The control group was fed compound feed(powder form),test group was fed fermentation liquid feed at first 1~2 days,compound feed supplemented with fermentation liquid feed during 3~5 days for transition,only fed compound feed at 6~7 days.The trial lasted for 7 days.The results showed as follows:(1)Compared with control group,the total solids intake of test group was significantly increased by 49.5%(P〈0.01).(2)The daily weight gain of control group and test group were-22.86 g/d·head and 12.86 g/d·head respectively;and test group was significantly increased by 35.72 g/d·head compared with control group(P〈0.01).In conclusion,fermentation liquid feed could relieve weaned stress of weaned piglets.
