摘　　要：早期断奶作为现代养羊业中常见的管理措施之一,对羔羊生长发育及其营养代谢具有重要影响。文章旨在系统分析早期断奶对羔羊生长、体型发育、营养代谢及行为应激反应的多重效应。早期断奶能够促进羔羊体重快速增长以及消化系统加速发育,但同时也可能导致骨骼发育不良、营养代谢失衡等问题。此外,早期断奶可能引发行为异常和应激反应增加,进而影响羔羊长期健康及生产性能。为此,文章探讨个性化及精准化断奶策略,以期最大限度减轻早期断奶对羔羊的不利影响,推动养羊业可持续发展。Early weaning,as a common management practice in modern sheep farming,has significant impacts on lamb growth,development,and nutrient metabolism.This review aimed to systematically analyze the multifaceted effects of early weaning on lamb growth,body development,nutrient metabolism and behavioral stress responses.Early weaning could promote rapid weight gain and accelerated development of the digestive system in lambs;however,it might also lead to skeletal developmental issues and metabolic imbalances.Additionally,early weaning might trigger abnormal behaviors and increased stress responses,which could adversely affect long-term health and productivity.Therefore,personalized and precise weaning strategies were explored to minimize the negative impacts of early weaning on lambs,ultimately promoting the sustainable development of the sheep farming industry.
