Because of bunk life and transportation costs, wet corn gluten feed is only an option to producers that are in relative close proximity of the milling plant. Crude protein values have ranged from 17 percent to 26 percent and fat content has ranges from 1 to 7 percent. Therefore, regular feed testing is recommended or buy corn gluten feed that has a guaranteed analysis. The concentration of crude protein is about as twice as high in corn gluten feed as it is in corn grain. The amino acid content of corn gluten feed is about two times higher than in corn, but relative concentrations of the amino acid are similar.
Corn gluten feed is low in calcium but has significant amounts of phosphorus.
The desired ratio of feeding cattle is a minimum of 1.5-2 to 1 calcium to phosphorus. Therefore, corn gluten feed fed at high levels without calcium supplementation could result in urinary calculi problems. Trace mineral and vitamin levels can vary greatly from batch to batch. If diets are formulated to meet he the protein requirements and the diets are similar in energy, then corn gluten feed is approximately equal to soybean meal as a protein source. However, quality of amino acid content is lower for corn gluten feed than soybean meal.
