摘　　要：本试验选用大白猪×内蒙黑猪杂交F1代18窝，共161头仔猪，随机分为6组。以正大SP—5—A浓缩饲料做为对照组迸行了筛选研究。试验结果表明，在被筛选5个配方中，用Ⅲ号配方配制的Ⅲ号日粮饲喂仔猪，仔楮21～35d龄日增重与正大料接近（P＞0．05）、35～50d龄日增重比正大料提高13．21％（P＜0．05）。消化代谢试验结果也指出，50～60d龄仔猪饲喂Ⅲ号料，其于物质、能量、粗蛋白、粗灰分的消化率分别比正大料提高1．12％、4．58％、7．36％和10．33％，氮的沉积提高4．40％，但差升均不显著（P＞0．05）。18 Littles (161 piglet's ) of L. Yorkshire x Inner Mongolia Black's crossbreeding F1 generations were Selected and randomly divided .into 6 groups in the trail. Group 1—5 were used as experimental groups and group 6 (fed with Zhengda's SP —S—A concentrated feed) was used as contral. The objective of this study was to select the best piglet's concentrated feed. The results showed that: The feed given in group 3 was the best one. During the 21—35th day old, the growth rate of piglets in group 3 were the same as that of the control (P<0. 05), but during the 35—50th day old, the piglets daily gain in group 3 was higher than that of the contral by 13. 2% (P<0. 05).The result of digestive and metabolic trails also indicated that the difference of digestibilities of DM. cp. Energy, Ash. and Nitrogen—balance between group 3 and the control (S. P. S. A) were not significant (P>0. 05).
