Abstract

A 35-day feeding trial was performed to assess the effects of the dietary supplementation of calcium formate alone and combination of multi-acid and essential oils on body weight gain, feed consumption, feed conversion ratio, percent livability and carcass yield of broilers. A total of 360 commercial broiler chicks were randomly distributed into three dietary treatments arranged in completely randomized design (CRD). Each treatment was replicated 10 times with 12 birds per replicate. The supplement used was an organic salt, calcium formate and multi-acid blend plus essential oils which were mixed with corn-soybean meal based diets at a rate of 0.3% of the starter diet and 0.1% of the grower-finisher diets. The broilers treated with calcium formate significantly exhibited better feed efficiency by 9.5% and an increase income over feed and chick costs based on percent livability by 18.11% relative to the non-supplemented group. As for the meat-types supplemented with multi-acid blend plus essential oils, they also showed better feed conversion by 7% and an increase in income over feed and chick costs based on percent livability by 13.35% relative to the control group. However, no significant differences were observed in the live body weight, weight gain, livability and carcass yield of supplemented and unsupplemented broilers. Diet supplementation with calcium formate and multi-acid blend plus essential oils improved feed conversion ratio and increased profitability.
