Soybean as supplement of growing cattle on tropical pasture: effects on intake, digestibility and animal performance
An indoor trial was conducted with weaning heifers (experiment 1). Raw whole soybean (RSB), whole soybean heated with steam (SHSB) and extruded whole soybean (EXSB) were given as supplements at 0.7% of live weight (LW). One group was the control, with no supplement. All supplements increased total...
