反刍动物饲料碳水化合物和蛋白质组分划分及消化道代谢规律
Division of Carbohydrate and Protein Fractions in Feed for Ruminants and Their Metabolism in Digestive Tract
摘要
Abstract
Carbohydrate and protein account for the most of feed nutrients, and accurate assessment of their nu-tritional values and ruminal metabolism become more and more significant.Cornell Net Carbohydrate and Pro-tein System( CNCPS) as an important method to evaluate feeds nutritional values, has not been widely used in ruminant production in China.This paper systematically reviewed the division of carbohydrate and protein frac-tions in CNCPS and their changes, as well as revealed ht e diversity of carbohydrate and protein fractions in dif-ferent feedstuffs and variation of rumen degradation rate (Kd) and passage rate (Kp).The relationship and difference between CNCPS system andother assessment systems were also reviewed.关键词
