The shape of the beef gain roughage‐concentrate isoquant is examined. Data from two beef‐feeding experiments designed to investigate response from alternative combinations of roughage and concentrate are utilized. Isoquants derived from estimated production functions are compared with directly estimated isoquants. The estimates indicate that the isoquant is not strictly convex to the origin. The nonconvex region is more pronounced in estimates obtained from data of steers fed diethylstilbestrol.
