Abstract

A 35-day feeding trial was conducted to evaluate the effects of dietary supplementation of thyme and peppermint derived feed additive on live body weight, body weight gain, feed consumption, feed consumption, feed conversion ratio, percent livability, and carcass yield of broilers. A total of 180 straight run Cobb broiler chicks were randomly assigned into three dietary treatments following the randomized complete block design (RCBD), each treatment was replicated 5 times each having 12 birds per replicate in a cage. The supplement that was used in the study was a phytogenic feed addictive derived thyme and peppermint extracts which was mixed with a corn-soybean based starter and finisher diets. The first treatment was the control, the second treatment was a basal diet with antibiotic growth promotant which was added at the rate of 500g/ton, and the third treatment was the basal diet with the thyme and peppermint derived feed additive which was mixed to the basal diet at the rate of 100g/ton. The results showed no significant differences in the live body weight, weight gain, feed consumption, feed conversion ratio, percent livability, and carcass yield (dressing percentage and breast meat yield). The supplementation of thyme and peppermint derived feed additive did not show significant effects in the study.
