A study was carried out to investigate the effect of feeding non-conventional feedstuffs, dried rumen content (DRC) and castor oil seed cake (COSC), at different inclusion levels to broilers. A total of 528 one-week-old Abbo Acres broiler chicks were fed starter and finisher experimental diets for seven weeks in a 4 x 10 factorial experimental design. Each non-conventional feedstuff was mixed in the ration at 0, 5, 10 and 15% levels of inclusion and a mixture of the two at 0, 25, 50 and 75% inclusion levels. At 7 weeks of age, feed type and diet significantly (P < 0.05) influenced the body weight (BW) as birds fed the 5% DRC, 5% COSC, 15% COSC and the CNTRL registered significantly (P < 0.05) higher average body weights (1.73 ± 0.5 kg, 1.70 ± 0.5 kg, 1.68 ± 0.5 kg and 1.70 ± 0.3 kg) respectively while those fed the 50% and 75% MXT registered significantly (P < 0.001) lower average body weights (0.96 ± 0.5 kg and 0.79±0.7kg) respectively. Feed efficiency (FE) of the birds, especially the birds fed the 50% (BW = 0.96 ± 0.5kg; FE = 3.48) and 75% (BW = 0.79 ± 0.7 kg; FE = 2.80) mixture were negatively depressed. Generally throughout the study period, birds fed the mixture at 50% and 75% recorded very low average body weights, while those fed the 5% DRC, 5% COSC and 25% MXT registered high average body weights. The best carcass yield was from birds fed the control (72.5 ± 1.04%), 5% DRC (73.2 ± 1.5%) and 15% DRC (72.1 ± 1.39) and birds fed the 10% DRC and 50% MXT had zero fat deposits. Inclusion of dried rumen content and castor oil seed cake significantly improved the performance with reduced cost of feed per kilogram weight gain over the control.

Key words:
Broiler chicken, performance, non-conventional feed stuff, carcass, cost.
