Anti-nutritional Factors of Composite Mango (Mangifera indica) Fruit Reject Meal and Its Value in the Nutrition of Finisher Broiler Chickens

Aim: Investigation was made to ascertain the level of some anti-nutrients in composite mango fruit reject meal (MFRM) and its effect on the performance of finisher broiler chickens.

Methodology: Mango fruit reject meal was analysed for anti-nutritional factors and incorporated into finisher broiler diets at 0, 11, 12, 13 and 14% to obtain five diets. Two hundred 28-day-old Arbor Acre broiler chickens were randomly allocated to the five dietary treatments in a completely randomised design (CRD), and fed for 35 days.

Results: Anti-nutritional factor levels were; tannin 2.10%, phytate 0.48%, saponin 2.96%, flavonoid 3.77% and oxalate was 3.35%. Mean final body weights and daily weight gains were significantly depressed (P<0.05) at 11% and 13% level of MFRM inclusion but similar to the control at 12% and 14% MFRM. There was no significant difference (P>0.05) for feed intake and digestibility of nutrients among the treatment groups. The cost/kg weight gain was not significantly affected (P>0.05) as well.

Conclusion: Mango fruit reject meal supported growth performance of finisher broiler chickens at 12% and 14% level comparable to maize, and 14% inclusion of MFRM was optimal.
