羊驼消化系统特性及营养需求.

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.
