Soybean Residue as a Feed Source for Cattle
This time of year it isn’t uncommon to see cattle grazing on corn, milo and soybean residue. However, it is unlikely cattle can graze on soybean stubble alone. The low nutrient value of soybean residue is not adequate to sustain even a small herd of cattle.
Soybeans are generally considered to be a high protein plant. However, the majority of this protein is found in the soybean itself. The leftover plant residue contains little protein.
The minimum amount of crude protein needed to support a dry beef cow is 7 to 8 percent. Soybean pods and stems contain only about 4 to 6 percent crude protein. The soybean leaves in residue contain up to 12 percent protein, but only 1/3 of this material is actually digestible by the cow.
Energy levels are low in soybean residue as well. With total digestible nutrient levels (TDN) averaging between 35 and 45 percent, cows lose condition and weight rapidly.
Soybean residue doesn’t have to go to waste. It can be baled and used to extend higher quality hay or silage or it can be grazed along with corn or milo stalks. In return, the nutrition of these higher quality feeds will make up for the deficiencies in soybean residue.
