Dry matter yield of grain sorghum alone
averaged more than 1.0 ton per acre higher
than that of intercropped grain sorghum-soybeans
in both 1988 and 1989. All silage yields
were lower in 1989 because of drought. Grain
sorghum silage had less NDF and ADF, but
intercropped silages had over 4 percentage
units more crude protein. Digestibility coefficients
for crude protein, NDF, and ADF
tended to favor intercropped silages, but yearling
steer performance favored grain sorghum
silage. Studies over 4 years (1986 to 1989)
suggest that intercropping might be more
beneficial for dairy cattle producers than beef
producers.
