Popis: This study evaluated the effects of including various levels of whole cottonseed (WC) or one level of soybean oil (SO) in high concentrate diets fed to finishing beef cattle. Two hundred eighty Nellore bulls were blocked by initial body weight (BW = 349 ± 33 kg), assigned to 40 feedlot pens and pens within weight block were randomly assigned to treatments: five levels of inclusion of WC [0%, (WC0); 8%, (WC8); 16%, (WC16); 24% (WC24); and 32% (WC32); dry matter (DM) basis] in diets containing 13% (DM basis) of sugarcane bagasse. One additional treatment was formulated to contain similar concentration of lipid as diet WC32 but with no WC, rather using soybean oil (SO). When averaged across the total feeding period, increasing dietary level of WC affected DM intake (DMI), final body weight, average daily gain (ADG), and feed efficiency (G:F; quadratic; P ≤ 0.01). Compared to WC0, diet SO decreased DMI (P
