Abstract: The study was carried out to evaluate the effect of sun-dried cassava peels supplementation on the performance of weaner pigs. To realize this objective, twenty-four crossbred weaner pigs weighing averagely 8.5±2.5 kg were used for the study. They were allocated into four treatment groups with three replicates in a completely randomized design. Feed intake, live weight and weight gain were determined using weighing scale (2.5 kg Salter scale) while feed conversion ratio was determine by simple ratio of weight gain/feed intake (kg). The results from the analysis of variance showed no significant (p>0.05) differences in the efficiency of feed utilization among the test diets, even though diet 4 had the best feed efficiency. The control diet was superior to other diets in the feed intake measurements. The body anthropometric measurements (BAM) were determined using designer’s measuring tape. This parameter (BAM) followed the same trend as in the feed intake except in body weight which excelled in diet 4. In terms of economy and cost benefit, diet 3 was the cheapest followed by diet 1, 2 and 4. Dietary inclusion of DCP and whole maize at 30 and 20%, respectively resulted in better economics of production. Diet 4, with high content of maize, had the best feed conversion efficiency but failed to promote the most profitable pig growth. Although, diet 3, with 30% DCP and 20% whole maize was less efficient in promoting growth, it was the most cost effective and increased profitability because 30% DCP and 20% whole maize are cheaper than 50% dried cassava peels as ingredients for weaner pig rations.
