The effects of 1.35, 1.8, or 2.25 kg dry matter (DM) of cottonseed cake, with (1.85 kg DM) or without molasses, on straw intake, diet digestibility, live-weight change, excretion of purine derivative (PD), and milk production of Boran (Bos indicus) cows were studied. There were no significant (P ...
