In a completely randomized design experiment, 90 day old chicks were divided into 5 treatment groups and given the following dietry regimes. During the brooding period (day 0-week 2) all birds were offered a commercial starter ration containing 21% crude protein (CP). Following the brooding period the birds were offered a commercial grower ration to which was added 0, 5, 10, 15 and 20% banana stem meal (BSM) respectively, for two weeks. During the finishing period (weeks 5-6) all birds in all treatments were given a commercial finisher ration containing 20% CP and 3100 kcal/kg ME. Each treatment was replicated 3 times with 6 birds in each replicate. Weekly body weight, body weight gain, feed intake and feed conversion ratio data were obtained and subjected to analyses of variance. The results showed that between 0-2 weeks, there were no significant differences in body weight gain and feed intake. During the growing period (3-4 weeks), there was significant reduction in growth performance and efficiency in birds fed Diet 5 as compared to the other diets. During the finishing peroid (5-6 weeks) there were no significant differences in the final body weight, but there was an improvement in the FCR and a significant increase in weight gains. The results suggest that there was compensatory growth as a result of poor nutrition during the third and fourth week of the growing period.
