Soybeans have an average protein level of 35-45% while corn averages only about 5-7% protein level. The roasting of grain is a process that heats the grain to make it more easily consumed by the animal, with soybeans the fat (energy) portion is utilized more efficiently. Roasting soybeans lowers soluble protein while increasing bypass protein. RUP (Rumen Undegradable Protein) makes up 40-45% of crude protein in roasted beans vs only 25% in raw soybeans. Roasted soybeans are naturally rich in high energy oils, naturally well balanced with body building protein, naturally high in essential vitamins, minerals and trace elements. Roasted Soybeans contain 17% fat, that's three times greater than corn and is equal to almost 10% more energy. High energy diets help put muscle and fat back on the animal during stressful times such as rutting season, growing periods, and fawning. Adding roasted soybeans to a deer's diet can help improve antler/body size and strength, increase reproductive performance and promote healthier fawns. The aroma of roasted soybeans makes them much more attractive and increases palatability and consumption.
Roasted Soybeans mix well with corn and can be used in spinner feeders, gravity feeders, bulk feeders or spread right on the ground. Below is a table of mixing ratios for desired protein levels.
Protein Level Amount of Roasted Soybeans Amount of Corn
16% 25% 75%
18% 37.5% 62.5%
20% 45% 55%
22% 50% 50%
Deer love the taste of soybeans and are naturally attracted to them. Soybeans are an excellent source of energy for deer especially during the winter and adverse conditions. Add soybeans to your feeders to achieve the necessary protein ratios needed to positively impact deer health. For a DIY feed ration we suggest mixing 30% Roasted Soybeans, 10% RWWP Maximizer Plus Feed Concentrate & 60% Corn (preferably rolled or lightly cracked).
