This experiment was conducted at Andassa Livestock Research Center (ALRC) to evaluate the growth performances of RIR starter and grower chicken fed a ration containing different levels of QPM and normal maize. The trial was carried out using completely randomized design for a period of 16 weeks. The results of both the starter and grower feeding phases revealed that there was significant difference ( P < 0.05) in body weight, daily weight gain and mortality rate of chicks between the control groups and those fed various levels of QPM in the ration. During the starter phase there was no significant difference ( P > 0.05) in final body weight among chicks fed different levels of QPM in the ration. Chicken fed a ration containing different levels of QPM (49-55% in the ration) showed significantly (P < 0.05) lower feed conversion ratio compared to chicken fed local maize. The lowest levels (49 and 51%) of QPM in the ration resulted in the highest mortality rate of chicks than the highest levels (53 and 55%) of QPM and the control diet. During the grower phase, chicken fed a ration containing different proportions of QPM (52-58%) showed the highest average final body weight and average daily weight gain than those fed a ration containing normal maize. On the other hand, chicken fed with a ration containing local maize were significantly higher in feed conversion ratio than those fed with different levels of QPM. The highest mortality rate was recorded only on chicks fed with a ration containing 54% QPM. Hence, it is recommended that inclusion of over 49 and 51% QPM in the ration of starter and grower chicks respectively was found to be promising in terms of body weight gain.
