营养素改善藏母猪繁殖性能的可能性分析

Probability of Improving Reproductive Performance of Tibetan Sows by Nutrients

在高原缺氧和高辐射条件下,生活在青藏高原及周边地区的藏母猪繁殖性能较弱,主要表现为产仔数低,仔猪断奶时间长、生长速度缓慢等,因此难以扩大生产规模。与此同时,国内外对藏母猪的营养学研究比较匮乏,尤其欠缺对改善藏母猪繁殖性能的理论指导。本文从藏母猪的生理特点入手,结合近年来对藏猪和其他高原生物基因测序的研究结果,分析了蛋白质(氨基酸)、碳水化合物、脂肪和维生素等营养素对其繁殖性能的可能作用,以期为未来藏母猪的营养学研究和繁殖性能的改善提供理论帮助。

Tibetan sows live in and around the Qinghai-Tibet Plateau under the condition of high altitude hypoxia and high radiation,they have the disadvantages of weak reproductive performance,such as low litter size,long weaning time and slow growth rate of piglets,so it is difficult to expand the production scale.At the same time,there is a lack of nutrition research on Tibetan sows at home and abroad,especially lack of theoretical guidance to improve reproductive performance of Tibetan sows.Based on physiological characteristics of Tibetan sows,this paper summarized research results of gene sequencing of Tibetan pigs and other plateau organisms,and analyzed the possible effects of protein(amino acid),carbohydrate,fat and vitamin on reproductive performance of Tibetan sows,so as to provide theoretical bases for future nutrition research of Tibetan sows and improving reproductive performance.
