Technical Abstract: Protein supplements for livestock are costly. In recent research in southern WI, lablab bean grown with corn increased forage CP concentration over monoculture corn without compromising forage yield or potential milk production per acre. Corn was intercropped with each of three climbing beans: lablab, velvet, and scarlet runner; or grown in monoculture. Results show lablab grown with corn has the greatest potential to increase crude protein concentration over monoculture corn without compromising forage yield or milk per acre, and thus potentially increasing corn silage crop value in the northern US.
