EFFECT OF GRADED LEVELS OF BEAN (Phaseolus vulgaris) SIEVATE ON CARCASS AND INTERNAL ORGAN CHARACTERISTICS OF FINISHER BROILER CHICKENS

Abstract

A 56 - day feeding trial was conducted to evaluate the effect of different levels of bean sievate (Phaseolus vulgaris) on carcass and internal organ characteristics of broiler finisher chickens. One hundred and fifty (150) day - old Arbor Acre broiler chicks were used in the study. The birds were randomly assigned to five dietary treatment groups in a Completely Randomized Design (CRD) to represent treatments T1, T2, T3, T4 and T5 respectively. Each treatment had thirty (30) birds and replicated thrice with ten (10) birds per replicate. The inclusion levels were 0, 5, 10, 15 and 20% respectively. Treatment one (T1) served as the control and had no bean sievate meal. Feed and water were given ad-libitum to the birds, while other management procedures were equally adhered to. Data on carcass characteristics were obtained by selecting two birds per replicate with weight closest to the group average for carcass evaluation. Internal organs were weighed and recorded accordingly. Results obtained were subjected to one way ANOVA. Results indicated that final live weight (1.70-1-94kg) and dressed weight (1.25-1.41kg) showed significant (p<0.05) differences in all the treatment groups as the replacement levels of bean sievate increases in the diets. Internal organs also followed the same trend. Weight of liver, heart, gizzard and intestine also showed significant (p<0.05) differences, except kidney. The study therefore concluded that 15% inclusion level of fermented bean sievate in the diets of finisher broiler birds could improve carcass yield and internal organ development.
