The difference may be due to amount of soybean particles contained. Previous studies at this location showed soyhulls to have excellent feed value and to be an economical ration ingredient for growing beef calves. This half of the plant's production is potentially available as a roughage, energy, and low protein feed source for grazing ruminants. The number of days that feed is required must be determined. This will vary from around 90 to 150 days, depending on the climate in your area and the amount of stockpiled forage available.
Stockpiled forage is an excellent way to reduce stored feed requirements.
