Replacing sorghum with palm kernel cake in the diet decreased intake without altering crossbred cattle performance.

Palm kernel cake is a viable alternative for use in cattle feed to reduce production costs. The aim of this study was to evaluate the effects of concentrations in diet dry matter (DM) of palm kernel cake on intake and digestibility of nutrients and performance of cattle finished in a feedlot system. Forty non-castrated crossbred cattle, with an average age of 24 ± 2 months and an average weight of 331.12 ± 36.20 kg, were distributed among four treatments (control 0%, without heart of palm kernel cake in the diet; 8%, 16%, and 24% of palm kernel cake in diet DM). Variance and regression analysis were performed in function of the palm kernel cake concentrations in diet DM (P   0.05) of palm kernel cake on average daily gain or feed conversion were observed. The palm kernel cake can be included in the diet of crossbred bulls finished in confinement at concentrations in diet DM of up to 24%, as it has not influenced performance.
