【摘要】 将6窝(共58头)1日龄长大哺乳仔猪分三个阶段进行试验,结果表明:7～21日龄阶段,两处理组间营养物质消化率差异不显著(P>0.05),哺乳仔猪的平均日增重差异不显著(P>0.05);22～40日龄阶段,2.0%乳糖组中营养物质消化率极显著低于4.0%乳糖组(P<0.01),4.0%乳糖组仔猪平均日增重显著高于2.0%乳糖组(P<0.05);在41～60日龄阶段,1.0%乳糖组蛋白质、粗纤维、总磷、铜和铁的消化率极显著低于3.0%乳糖组(P<0.01),3.0%乳糖组仔猪平均日增重显著高于1.0%乳糖组(P<0.05)。更多还原

【Abstract】 58 piglets aged 1day were allotted into two treatments to conduct a 3-phrase trial, results showed: from 7th to 21st day, there was no significant difference(P>0.05) between this two treatments in terms of digestibility and average daily gain;from 22nd to 40th day, the digestibility of nutrient of 2.0% lactose-contained diet was significantly (P<0.01) lower than that of 4.0% lactose-contained diet; the average daily gain of piglets offered 4% lactose was significantly higher(P<0.05) than that of piglets offered 2% lactose;From 41st to 60th day, the digestibility of nutrient of 1.0% lactose-contained diet was significantly(P<0.01) lower than that of 3.0% lactose-contained diet; the average daily gain of piglets offered 3% lactose was significantly (P<0.05) higher than that of piglets offered 1% lactose.更多还原
