The digestive system of newborn ruminant functions is similar to monogastric animals, and therefore milk flows into the abomasum instead of rumen for digestion. The rumen undergoes tremendous changes over time in terms of structure, function, and microbiome. These changes contribute to the smooth transition from the dependence on liquid diets to solid diets. Goat kids are usually separated at early ages from their dams in commercial intensive systems. The separation from dams minimizes the transfer of microbiota from dams to newborns. In this review, understanding how weaning times and methodologies could affect the normal development and growth of newborn goats may facilitate the development of new feeding strategies to control stress in further studies.
新生反刍动物的消化系统功能与单胃动物相似，因此乳汁流入皱胃而非瘤胃进行消化。随着时间的推移，瘤胃在结构、功能和微生物群方面会发生巨大变化。这些变化有助于从依赖流食平稳过渡到固体食物。在商业化密集养殖系统中，山羊幼崽通常在早期就与母羊分开。与母羊分开可最大程度减少微生物群从母羊向新生幼崽的转移。在本综述中，了解断奶时间和方法如何影响新生山羊的正常发育和生长，可能有助于在进一步研究中制定新的饲养策略以控制应激。
