Studies quantifying the differences between bulls and steers have generally shown that bulls gain more rapidly and more efficiently than steers and produce leaner carcasses. The average of these studies gave bulls a 17 percent advantage in average daily gain and a 13 percent advantage in converting feed to liveweight gain. Feed efficiencies reported in these studies were determined on animals fed to similar ages or weights. The effects of sex condition on feed efficiency of animals fed to a similar fat composition or marbling endpoint needs to be examined.
