Effect of mimosa diplotricha leaf meal on the organ weights and organoleptic properties of three broiler strains

Abstract

The effect of Mimosa diplotricha leaf meal (MDLM) on the organ weights and organoleptic properties of three broiler breeds was studied using 120 day-old chicks reared for eight weeks. The work was carried out using randomized complete block design. The breeds namely Arbo Acre, Cobbs and Ross were designated as treatment 1, 2 and 3, respectively with three replicates each. Two diet groups; diet with 2% Mimosa diplotricha leaf meal and diets without the leaf meal were administered. The organ weights and organoleptic properties of the broiler strains were determined. Mimosa diplotricha had no significant effect on the heart, spleen, gizzard and liver weights of the birds. Furthermore, similar spleen weights were obtained across the breeds, while discrepancies were observed in heart, gizzard and liver weights of the breeds. Cobbs best tolerated the leaf meal with respect to organ weights and gave the best taste, flavor intensity and desirability. Results showed that Mimosa diplotricha could be used as a partial replacement of wheat offal in broiler diets. However, lesser concentration may be used for Ross breed. Regardless of feed inclusion, Cobbs is observed as the best breed in comparison to Arbo acre and Ross broilers with respect to organoleptic properties and organ weights.
