Abstract

We investigated the degradation of betaine in the rumen by a continuous supply of betaine to dairy cows. After 24 h of betaine incubation using rumen fluid from dairy cows, more than 80% of the betaine remained undegraded. Furthermore, the continuous supply of betaine for about 70 d did not influence the in vitro degradation of betaine.
