The FI, BW gain, and FCR data are given in Table 3. The effects of dietary peppermint on performance were not significantin different age classes. During 7–35 days of age, BW gain was remained constant among experimental treatments whereasFI showed incremental trend (P = 0.099) resulting in impairing FCR with inclusion of peppermint in the diet (P = 0.062).The effects of dietary peppermint on carcass attributes were not significant (Table 4). However, carcass percent showed a
