Interpretive Summary:

Technical Abstract: Monensin has the potential to increase the efficiency of N utilization in dairy cows fed fresh forage and to decrease fecal N excretion. Because of the decrease in ruminal ammonia and increase in apparent N digestibility, the results of our trial suggest that monensin was sparing amino acids. The results of this study demonstrate that the Cornell Net Carbohydrate Protein System can be used to formulate diets for dairy cows consuming fresh forages and it gives realistic predictions of performance under these conditions.
