Twenty four (24) crossbred grower pigs of Large White, Landrace, Hampshire and Duroc breeds, which averaged 43.96kg liveweight, were allocated in groups of4 pigs and two replicates, to each of 3 diets. Diet I was a maize-based control while in diets II and III, cassava root meal (CRM) solely, or its mixture with brewers yeast slurry (CRM-BYS) replaced all of the maize in the control. The pigs were group - housed in concrete floor pens where they were fed the test diets to appetite, and had water ad libitum over a 30-day period. Performance parameters were measured during this period, and at the end of it, 4 pigs from each treatment were slaughtered and their carcasses characterized. Average daily feed (ADF), average daily gain (ADG), feed/gain ratio for diets I, II and III were 2.08, 2.07, and 2.01 kg; 0.63, 0.60 and 0.64 kg; 331, 3.48 and 3.15 respectively. The differences were not significant (P >.05). Feed cost/kg liveweight gain was significantly (P .05) in the different diets. These data show a net advantage of replacing dietary maize with cassava root meal or its mixture with brewers yeast slurry for growing-finishing pigs under the defined conditions.
