The ruminants' productive capacity was enhanced by the addition of protein sources high in non-hydrolyzed protein to the Rumen because of its palatability, availability in large quantities, balanced amino acid composition, and rapid decomposition in the Rumen; the various commonly used soybean meal is one of the protein sources in ruminant feed and the most widely used in nutrition. However, its high cost led to the search for alternatives to it at a lower cost; one of these additives is corn gluten meal, which is a by-product of the manufacturing because corn gluten gain has a protein content of 60–65% crude protein, it eliminates the need to supplement traditional feed with protein sources, lowering the cost of feed. Urea is one of the most essential nitrogenous additives that are used to improve the nutritional value and benefit from coarse feed, and because it has a value almost equal to the concentrates for ruminants, as urea decomposes in the Rumen at high speed to ammonia, which is used to produce amino acids and microbial protein by microbiology, and those substances are utilized protein substances by the animal.
