摘　　要：本试验旨在研究不同乳清粉水平及料型对断奶仔猪生长性能、腹泻率、营养物质全肠道表观消化率和血液指标的影响。将144头杜×长×大断奶仔猪随机分为4个处理,分别饲喂6%乳清粉粉料(A)、6%乳清粉颗粒料(B)、12%乳清粉粉料(C)、12%乳清粉颗粒料(D),每个处理6个重复,每个重复6头猪。结果表明:B组仔猪平均日增重显著高于粉料组(P<0.05);A组仔猪平均日采食量显著高于颗粒料组(P<0.05);B组仔猪饲料转化率显著优于粉料组(P<0.05);各处理之间,腹泻率、干物质、粗蛋白、有机物和总能的全肠道表观消化率以及血糖、尿素氮、总蛋白、白蛋白、球蛋白的含量均无显著差异(P>0.05)。因此,颗粒料在断奶仔猪生产性能上显著好于粉料,6%乳清粉颗粒饲喂效果最佳。This experiment was conducted to study the effects of different levels of dried whey and feed types on weaned piglets growth performance, diarrhea rate, nutrients apparent digestibility in the total tract and blood indicators. A total of 144 Duroc xLandrace xYorkshire crossbred weaning piglets were randomly divided into four treatments, including 6% dried whey mash （A）, 6% dried whey pellet （B）, 12% dried whey mash （C） and 12% dried whey pellet （D）, with 6 replicates per treatment and 6 piglets per replicate. The results showed that： Average daily gain of weaned piglets in B group was significantly higher than that in mash group （P〈0.05）; Average daily feed intake of weaned piglets in A group was significantly higher than that in pellet group （P〈0.05）; Feed conversion rate of weaned piglets in B group was significantly lower than that in mash group （P〈0.05）; There were no significant difference between treatments on the diarrhea rates, the full intestine apparent digestibility of dry matter, crude protein, organic matter, gross energy and the concentration of the weaned piglets serum glucose, serum urea nitrogen, serum total protein, albumin, globulin （P〉0.05）. In summary, growth performance of weaned piglets fed pellet were significantly better than that fed mash diets and the 6% dried whey pellet diets had the best growth performance.
