Effect of different rapidly fermentable carbohydrates sources addition on in vitro neutral detergent fibre (NDF) digestibility

摘要

With fibre being the major feed component of ruminant diets it is important to maximise its digestion in then rumen. By adding specific carbohydrates to a diet, it may be possible to improve fibre digestion and subsequent livestock performance.Since the rumen itself is well designed to ferment fibre to obtain energy and drive microbial protein production, factors that are able to increase or depress this process will have an impact on how the diet performs. It is known that other dietary energy sources are also able to impact fibre digestibility. The aim of the current study was to evaluate different rapidly fermentable carbohydrates sources for their effects on in vitro ruminal NDF digestibility.
