A trial was conducted using 40 Commercial Merino X Border Leicester male intact sheep fed in feedlot, with 30% Palm kernel cake (PKC) in all rations, plus either ground maize, maize with cassava, maize with palm sago or sago alone in four treatment groups. The trial was to determine the effects of maize, cassava and sago on the growth performance of sheep, fed on the isonitrogenous and isocaloric diets. It was also to determine the effects of the sodium molybdate as a chelating agent to bind excess copper, when used with the high copper PKC feed in a feedlot. Sheep on maize-based ration had the highest average daily gain (ADG), feed conversion ratio (FCR) and cost per kg gain. The ADG were 192, 278, 159 and 138g, respectively. The highest and lowest FCR values were in sheep fed maize based diet amd sago based diet, respectively. Despite the high cost of maize and the low cost of palm sago the cost per kg gain was the lowest for the maize diet, followed by sago and cassava. The serum copper content of the animals were within the normal physiological levels thus indicating that the sodium molybdate had bound the copper in the feeds rendering it unavailable and prevented copper in the feeds rendering it unavailable and prevented copper toxicosis, despite the high levels of copper in the feeds offered.
