Abstract

The effect of supplementation of fishmeal as compared to urea on the rumen environment and ruminal feed degradation in Bali cows fed low-quality tropical grass hay was discussed. Both supplements reduced pH and increased rumen ammonia but the increase of rumen ammonia was more pronounced in urea than with fishmeal supplementation. The ruminal total, as well as individual VFAs (Acetate, Butyrate and Propionate) concentrations, were not affected by the supplementation of both urea and fishmeal but the Ruminal dry matter degradability was increased with fishmeal supplementation. It can be concluded that the supplementation of both urea and fishmeal improved the rumen environment and feed degradability in Bali cows maintained on low-quality tropical grass hay with fishmeal was proven to be the better supplement over urea.
