摘要：

The results of two fermentation experiments conducted with an artificial rumen (rumen simulation technique - Rusitec) are reported. The first experiment compared the fermentation characteristics of a medium quality hay with those of untreated or urea-ammonia treated rice straw. Urea-ammonia treatment increased the digestibility, Volatile Fatty Acid production and microbial dry matter output compared with untreated straw. The second experiment examined the effects of level of feeding and different roughage:concentrate ratios on fermentation characteristics of urea-ammonia treated rice straw. It is clear that although Rusitec is an in vitro technique it has advantages over other in vitro techniques as it can provide much more information on rumen fermentation characteristics of a given feed.
