Abstract: 144 day-old broiler chicks of the Oba Marshal strain were used to evaluate the effect of feeding Jatropha tanjorensis leaf meal as a growth promoter on the growth performance, carcass characteristics and sensory properties of broiler chicken. The birds were randomly allocated to four dietary treatments, after adjustment to the deep litter pens for one week. Each treatment was replicated three times with 12 chicks per replicate. The treatments were 0.0, 0.5, 1.0 and 1.5 % dietary inclusion level of Jatropha tanjorensis (JT) leaf meal tagged T1, T2, T3 and T4 respectively. Feed and water were supplied to the birds ad libitum. At the end of the seven weeks feeding trial, one bird per replicate was randomly selected and fasted for 12 hours, and then slaughtered with a sharp knife through cervical dislocation. The slaughtered, plucked, eviscerated and dressed weights of the birds were then determined as well as the weights of the primal cuts. Part of the meat from the breast and drumsticks were cooked and used for sensory evaluation, using a semi-trained 20-man panelist based on a nine-point Hedonic scale. Data collected were analyzed using ANOVA based on the completely randomized design model; where means were significant (p<0.05), they were separated using Duncan Multiple Range Test. Results showed that the final body weight, total body weight gain, total feed intake, feed conversion ratio (FCR) and mortality were not significantly (P>0.05) affected by the dietary treatments at the starter phase However, at the finisher phase, the final body weight, total body weight gain as well as the average body weight gain of the birds increased incrementally as the dietary inclusion level of Jatropha tanjorensis leaf meal (JTLM) increased; with the values obtained for birds fed the 1.5 % JTLM being significantly (P<0.05) higher than those of the other treatments. Also, live weight, eviscerated weight and dressed weight were significantly (P<0.05) affected by the dietary treatments, with birds fed diet containing 1,5 % JTLM showing significantly (P<0.05) higher values than those of the other treatments. Of the sensory properties examined, only appearance and overall acceptability were significantly (P<0.05) affected by the dietary treatments; with the meat from birds fed 1.0 % JTLM having significantly higher scores for appearance and general acceptability, but not significantly different from the scores obtained for 1.5 % JTLM. Therefore, it can concluded that Jatropha tanjorensis leaf meal can be included in the diets of broiler chicken up to 1.5 %, especially at the finisher phase, for optimum growth performance, carcass characteristics and sensory properties of the meat of broiler chicken.
