We have not done creep trials using gluten. North Dakota State has done some. Following are my thoughts. To make a pellet that includes gluten that doesn't result in a lot of fines, the pellet would be 65% to maybe 70% gluten. This pellet would be a good energy source that is high in fiber but would also be a good protein source, as gluten will be between 19% to 24% crude protein. Because gluten is high in phosphorus, some calcium will be needed in the pellet to get the Ca:P ratio above the 1.25:1 ratio. The amount of sulfur in gluten is usually pretty consistent at about 0.4%. The maximum tolerable level of sulfur for beef cattle is 0.4%. The total intake of the calf will not be the pellets, but if you don't have an intake limiter in the pellet, intake could be over 50% of their total daily dry matter because this pellet will be very palatable. It may be wise to add some thiamine to the pellet in case the sulfur intake is high.
