Extract

Synchronising the availability of energy and nitrogen to the rumen microbes is considered to be important for enhancing output of microbial protein from the rumen. This is particularly relevant to diets based on grass silage (Chamberlain and Choung, 1995). In the rumen ammonia, is rapidly released from the substantial content of non-protein nitrogen compounds in grass silage and this requires a similarly rapid release of energy in the rumen to ensure efficient capture of ammonia. Different sources of carbohydrate may enhance rumen function to varying degrees. The aim of this study was to examine the effects of various carbohydrate sources on intake, rumen fermentation characteristics and digestibility in steers fed on grass silage.
