目的：母猪乳（SM）可能不能满足哺乳后期仔猪的营养需要。为此，本研究旨在探讨早期补饲商品乳（CM）对仔猪空肠黏膜形态、细菌群落及细菌代谢产物的影响。方法：选取10窝新生仔猪（[约克夏×长白] ×杜洛克），随机分为2组，每组5窝。对照组用母猪（SM）哺乳，试验组（CM补充剂）沿着哺乳期，在第4 ~ 28日龄期间添加CM补充剂。28 d时，CM组空肠乳糖酶活性显著降低，蔗糖酶活性和麦芽糖酶/乳糖酶比值显著升高（p
Objective: Sow milk (SM) may not be able to meet the piglet's nutritional needs in late lactation. Hence, this study was conducted to investigate the effects of early commercial milk (CM) supplement on the mucosal morphology, bacterial community and bacterial metabolites in jejunum of piglets.Methods: Ten litters of newborn piglets ([YorkshirexLandrace]xDuroc) were randomly divided into 2 groups of 5 litters. The piglets in the control group were suckled by the sow (SM), while the piglets in the treatment group (CM supplement) were supplemented with a CM supplement along with suckling from d 4 to d 28 of age.Results: No significant differences were observed about jejunal mucosal morphology on d 28 and d 35 between two groups. On d 28, the activity of lactase in the jejunum was significantly decreased in the CM group, while the activity of sucrase and the ratio of maltase to lactase were significantly increased (p
