低胎次母猪的繁殖现状及营养调控研究进展OA北大核心CSTPCD
Research Progress on Reproductive Status and Nutritional Regulation of Low-Parity Sows
低胎次母猪由于繁殖经验和生理发育的局限,繁殖性能常常不佳.影响其繁殖性能的关键因素主要包括卵巢功能、激素水平、子宫容量以及乳腺发育状况.日粮营养调控被证明是改善低胎次母猪繁殖性能的一种有效手段.通过合理搭配母猪日粮中的营养素(蛋白质、氨基酸、能量、氨基酸),可以为母猪提供均衡且全面的营养支持.因此,本文就低胎次母猪繁殖性能的现状进行梳理,深入分析影响其繁殖性能的主要因素,并探讨通过营养调控策略来提升其繁殖潜能的可能性.
Due to reproductive inexperience and physiological limitations,low-parity sows often exhibit poor reproductive performance.The key factors affecting their reproductive performance mainly manifest in ovarian function,hormone levels,uterine capacity,and mammary gland development status.To improve these conditions,dietary nutrition regulation has been proven to be an effective means.By properly formulating the nutrients(protein,amino acids,energy,and amino acids)in the daily diet of sows,balanced and comprehensive nutritional support can be provided.Therefore,this paper systematically reviews the current situation of reproductive performance in low-parity sows,analyzes in depth the main factors affecting their reproductive performance,and explores the possibility of enhancing their reproductive potential through nutritional regulation strategies.
