Kinetics fermentation and gas production of the neutral detergent-soluble fraction of fresh forage, silage and hay of Avena sativa

Abstract

Neutral detergent treatment to evaluate the structural polysaccharides (NDF) removes soluble sugars, pectin substances, starch and the non-carbohydrate fraction (Van Soest, 1991). Despite the widely recognized importance of neutral detergent-soluble carbohydrates (NDS) in the early stages of forage digestion, little is known about their digestion kinetics because most in vitro methods have studied the disappearance of insoluble cell wall components. However, knowledge of the degradation characteristics of both fractions is very important to formulate balanced diets for high-yielding animals. Using the in vitro gas production system........
