The Utilisation of Fishmeal or Urea Supplementation to Improve the Rumen Environment and Ruminal Feed Degradation in Bali Cows | Chapter 3 | Emerging Challenges in Environment and Earth Science Vol. 4

In Bali cows fed low-quality tropical grass hay, the impact of supplementing with fishmeal as opposed to urea on the rumen environment and ruminal feed breakdown was addressed. Both supplements decreased pH and raised rumen ammonia levels, whereas urea supplementation significantly increased rumen ammonia levels above fishmeal supplementation. The addition of urea and fishmeal had no effect on the ruminal total concentration or the concentrations of the individual VFAs (Acetate, Butyrate, and Propionate), but the addition of fishmeal increased the ruminal dry matter degradability. Conclusion: Supplementing Bali cows fed low-quality tropical grass hay with urea and fishmeal enhanced the rumen environment and increased feed degradability. Fishmeal, however, was found to be a superior supplement to urea.
