This study was carried out to determine the effects of long-term consumption of different levels of C. olitorius and O. gratissimum diet-inclusion on male Wistar rat. A total of thirty-five (35) rats (average weight of 80 g±10g) were purchased and randomly allotted into seven (7) treatment groups with graded levels of C. olitorius and O. gratissimum (2.5%, 5%, and 10%) while the control had neither C. olitorius nor O. gratissimum. The feed intakes, weight performance as well as their histology of the experimental rats were monitored for eight weeks. The results obtained showed that the highest level of feed intake was recorded for animals in the group fed 10% level of C. olitorius supplementation when compared to other treatment groups. A similar result was observed for the weight performance which can be attributed to the efficient utilization of feed consumption. Also, group of rats fed with the lowest supplementation (2.5%) of O. gratissimum showed a significant increase (P< 0.05) in the feed intake than the group fed with the highest supplementation (10%). Also, the weight gain by the rats fed 2.5% O. gratissimum diet supplementation had the highest weight gain. The observable increase in the feed intake, weight gain and feed efficiency seen in the lowest supplementation level (2.5%) can be attributed to the spicing and seasoning of food with O. gratissimum and as such could also increase the palatability of the food. Therefore, it can be concluded that the leaves of C. olitorius are palatable and highly nutritious and can improve growth performance. Whereas, it can also be found that 2.5% O. gratissimum supplementation has better palatability than other experimental diets which reflected on the performance characteristics of this treatment and imposed an adverse effect with increasing dosage at 10% O. gratissimum. Thus, intake of C. olitorius should be encouraged while O. gratissimum is advised to be taken as a spice, not as a soup.
