Body composition of broilers consuming forage meal of Mucuna deeringiana in the diet. Technical note


Abstract


Thirty-two male broilers of the hybrid HE21 were used to determine the body composition of broilers consuming forage meal of Mucuna deeringiana (velvet bean) in the diet. The animals were distributed into four treatments (experimental diets) and eight repetitions, according to completely randomized design. The control was based don maize-soybean. In the rest of the treatments, the cereal was substituted by 5, 10 and 15 % of velvet bean forage meal. After 42 d, the animals were weighed, slaughtered and removed their viscera to determine the carcasses weight. Later, they were sectioned in legs and chest. The content of excessive fat was determined. There were no differences
between treatments for the body composition, except, for the abdominal fat that decreased, compared to the control, 5.57 units (P < 0.05) with the inclusion of 15 % of velvet bean. It is concluded that with the substitution of 15 % of Mucuna deeringiana forage meal in the broilers diet, the carcass fat diminished without affecting the different edible portions.
Key words: body composition, broilers, Mucuna deeringiana forage meal.
