The objective of this work was to study the replacement of corn by cassava hulls, swept cassava meal or cassava scrapings on the average weight gain, feed intake, feed:gain ratio and carcass yields of feedlot heifers. Twenty-eight crossbreeding heifers averaging 365 kg LW and 24 months of age were allotted to a randomized blocks design in a 56 days experimental period, with four diets and seven replicates. There was no effect of replacement of corn by cassava products on average weight gain, feed:gain ratio and carcass yields. However, feed intake was smaller in the diets with cassava scrapings and by-product cassava.
