Growth and Carcass Traits of Chicken Supplemented with Preparations of Butterfly Pea (Clitoria ternatea) at Varying Inclusion Frequencies

The study was conducted to determine the growth performance and carcass traits of Cobb® Broiler broilers supplemented with different preparations of butterfly pea (Clitoria ternatea) at varying inclusion frequencies. The study used the 3x2 factorial in Completely Randomized Design, with the type of butterfly pea preparation as factor A (A1 – Control Group, A2 – butterfly pea flower (BPF) as fermented juice, and A3 – BPF decoction, both supplemented in drinking water (10%), whereas factor B was the frequency of supplementation (B1 – every day, B2 – every other day). Day-old Cobb broiler chicks with similar average weight of 50–60 grams were randomly distributed to six groups, which had three replicates each, and seven birds per replicate, for a total of 126 birds. The body weight, average weight gain, and feed conversion ratio revealed there was no interaction effect for the two factors, but there were highly significant differences among the control and BPF preparations, and between the two frequencies of supplementation. Butterfly pea flower-treated groups had better results than the control, with BPF-fermented juice (A2) having the best results, followed by BPF-decoction (A3). Between the frequencies, it was everyday supplementation (B1) that showed better performance values. No significant differences were observed on carcass traits including dressed weight, carcass percentage, and relative organ weights (liver, spleen, gizzard, and heart).
