Abstract

The aim of this study was to investigate the effect of N- carbamylglutamate supplements on protein metabolism and nitrogen utilization in lactating cows. The findings revealed that the total protein level in the experimental group was significantly greater than in the control group (p<0.05), suggesting an improvement in dietary nitrogen utilization efficiency. Additionally, albumin levels were increased in the experimental group, indicating enhanced protein synthesis and utilization. Ammonia levels were significantly lower in the experimental group (p<0.05), demonstrating enhanced metabolic utilization of ammonia nitrogen. Urea levels were also lower in this group (p<0.05), implying increased use of endogenous urea for microbial protein production. Creatinine levels, on the other hand, were higher in the experimental group (p<0.05), reflecting an increased utilization of ammonia nitrogen in the synthesis of nitrogenous compounds
