羊驼消化系统特性及营养需求

Digestive System Characteristics and Nutritional Requirements of Alpaca

羊驼原产于南美洲环境差、海拔高的平原地区。作为秘鲁等国家全民普遍养殖的家畜,羊驼凭借其优质的驼毛和高营养的肉、奶,被越来越多的国家引进以丰富动物物种。由于羊驼原产地独特的气候环境和地理条件,不同的引入国家需要对其饲养管理进行调整。我国羊驼饲养以粗饲料为主,混以精饲料并补充维生素、矿物质等。但不同地区羊驼营养需求也不同。为了更好地配制羊驼养殖的全混合饲料,对羊驼区别于牛、羊等普通反刍家畜的消化系统特性和其在不同国家的营养需求进行了综述,为后续配合羊驼全混合饲料提供依据。

Alpacas are native to the poor,high-altitude plains of South America.As a common breeding animal in Peru and other countries,it has been introduced to more and more countries to enrich animal species due to its high-quality camel hair,high nutritional meat and milk.Due to the unique climatic environment and geographical conditions of alpaca origin,the breeding management needs to be adjusted in different introduced countries.Chinese alpaca feed was mainly roughage,which mixed with concentrate feed and supplemented with vitamins,mineral trace elements and so on.However,the nutritional requirements of alpacas varied from region to region.In order to better prepare the full-priced pellet feed for alpaca farming,the digestive system characteristics,differences among alpacas,cattle,sheep and other common ruminants and their nutritional requirements in different countries were reviewed in this paper,so as to provide a basis for the follow-up of fullpriced pellet feed.
