摘　　要：选取胎数、体况、产仔日期相似的大白×长白二元杂交经产母猪共60头,随意分4组,每组15头母猪。对照组不加特殊食品用脂肪粉,试验组添加特殊食品用脂肪粉,旨在科学研究特殊食品用脂肪粉对哺乳母猪生产制造性能、营养物质消化利用率的影响。结果表明:日粮加上特殊食品用脂肪粉后,仔猪断奶重、仔猪日增重、母猪采食量和断奶后7 d母猪发情率均得到显著性提升(P<0.05);断奶仔猪存活率均得到提高,其中试验3组得到显著性提高(P<0.05);粗蛋白、粗脂肪、钙和磷的消化率均得到显著性提高(P<0.05);试验1组干物质消化率得到提高,但差异不显著(P>0.05),试验2组和试验3组干物质消化率得到显著高于对照组(P<0.05)。结果提示:哺乳母猪日粮中添加特殊食品用脂肪粉可以有效提高哺乳母猪生产制造性能、繁育性能,同时可提高哺乳母猪日粮营养物质消化率。Select Landrace×Yorkshire with similar fetal numbers,body conditions,and birth dates × A total of 60 crossbred sows were randomly divided into 4 groups,with 15 sows in each group.The control group did not add fat powder for special food,while the test group added fat powder for special food to study the effect of fat powder for special food on the production performance and nutrient digestibility of lactating sows.The results showed that the weaning weight of piglets,daily gain of piglets,feed intake of sows and oestrus rate of sows on the 7th day after weaning were significantly increased(P0.05);The survival rate of weaned piglets was improved,and the three groups were significantly improved(P0.05);The digestibility of crude protein,crude fat,calcium and phosphorus were significantly improved(P0.05);The dry matter digestibility of the first group was improved,but the difference was not significant(P0.05).The dry matter digestibility of the second group and the third group was significantly higher than that of the control group(P0.05).Result prompt:Adding fat powder for special foods to the diet of lactating sows can effectively improve the production performance and reproductive performance of lactating sows,and can improve the nutrient digestibility of the diet of lactating sows.
