Interpretive Summary:

Technical Abstract: The dietary protein requirement of cattle decreases as animals grow, and mature. Thus, it maybe possible to decrease the protein content of finishing diets to conserve nitrogen, and decrease ammonia emissions. This publicatoin gives a brief review of research conducted on phase feeding protein to finishing beef cattle. It appears that phase feeding protein has little effect on animal performance and decreases potential ammonia emissons by 10 to 30%.
