Effect of dietary supplementation of Monotheca buxifolia leaf powder on the growth performance of broiler chickens

Abstract

The aim of this study was to investigate the effect of dietary supplementation of Monotheca buxifolia leaf powder on the growth performance of broiler chickens. A total of 250 -1-day old broiler chicks (Ross 308) were randomly distributed into five treatments with five replicates and each replicate consists of ten birds. Prior to the arrival of birds, basal diet adequate in all nutrients was formulated according to the requirement of birds by Nutritional Research Council in 1994. Birds in treatment one was fed basal diet without Monotheca buxifolia leaf powder, those in treatment two, three, four and five were fed same diet with Monotheca buxifolia leaf powder at 100 g, 200 g, 300 g and 400 g respectively. The experiment lasted for 42 days and birds had unrestricted access to clean water and feed. A completely randomized experimental design was adopted and all management practices was strictly adhered to. Result on the phytochemical content of Monotheca buxifolia leaf powder flavonoids (863.2 mg/g), phenols (511.8 mg/g) and terpenoids (102.3 mg/g) were the most prominent compounds followed by saponins (72.56 mg/g), tannins (62.34 mg/g), alkaloids (41.88 mg/g) and steroids (30.41 mg/g). Average daily weight gain and average daily feed intake values which varied from 41.24 – 51.37 g/b and 103.7 – 107.5 g/b were higher among birds fed Monotheca buxifolia leaf powder (treatment two, three, four and five) relative to treatment one (P<0.05). Similarly, feed conversion ratio whose value ranged from 2.09 – 2.50 were significantly (P<0.05) influenced by the treatment. In conclusion, feeding broilers Monotheca buxifolia leaf powder up to 400 g/kg diet does not pose any detrimental effect on the performance of birds.
