摘要 开展了对36窝297头断乳仔猪腹泻频率及断奶前期限饲对增重的影响试验。试验表明:仔猪多在断奶后3-4天开始腹泻,6-9天腹泻达到高峰,三周内腹泻面可达79.3%;23.6%的仔猪在断奶后一周内失重,平均日增重为-51.6克;不同腹泻频率对仔猪后期增重影响差异不显著(P】0.05);仔猪断奶始重(X<sub>1</sub>)和前期日增重(X<sub>2</sub>)对保育期全程日增重(y)相关极显著(r<sub>1</sub>=0.259,r<sub>2</sub>=0.459,P【0.01),经回归分析,回归关系显著(y=214.31+15.95X<sub>1</sub>,y=339.2+0.48X<sub>2</sub>,P【0.01)。
