“…There was no significant (P>0.05) difference in the average weight gain of animals on 0, 20 and 40% PKC inclusion though, weight gain was significantly (P<0.01) high (1.33kg) for animal on 10% PKC followed by those fed 30% PKC inclusion (1.31kg). The average daily weight gain of 1.14-1.33Kg/day obtained in the present study was similar to Sani et al, (2015) 1.11-1.29Kg/day when diets containing graded levels of raw and parboiled rice offal were fed to Bunaji bulls, the weight gain of animals on diets containing 0, 20 and 40% PKC were similar to the AWG of 1.13 kg/d observed by Luziga (2005) in Boran crosses supplemented with molasses based concentrate but higher than those obtained in earlier studies reported by Lamidi et al, (2007) 0.69-0.91Kg/day, Idowu (2011) 0.40.66Kg/day, Madziga et al, (2013), 0.961.01Kg/day and 0.50-0.92kg/day reported by Goska et al, (2016) for matured bulls. Also, Feed conversion ratio (FCR) of 6.52-7.57 obtained in this study was similar to 6.26-6.93 obtained by Sani et al, (2015)but superior to 9.04-9.55, 13.71-22.4, 9.03-12.05 and 8.31-16.16 reported by Madziga et al, (2013), Idowu (2011) Lamidi, (2005 and Goska et al, (2016) respectively but FCR based on rice type (6.26-6.67), inclusion level (6.26-6.72) and interaction between rice type and inclusion level (6.26-6.93) reported by Sani (2014) for fattened bulls was superior to what was obtained in this study.…”
