Three hundred and sixty numbers of day old desi chicks were randomly divided into six treatment groups with three replicates of 20 chicks each per group. Out of 180 desi chicks were reared under deep litter system and remaining 180 chicks were reared under cage system. The experimental birds were fed with three different levels of dietary crude protein (18, 20 and 22 per cent) with an isocaloric feed of 2800 Kcal ME / kg and potable water given ad libitum. Standard management practices were adopted throughout the experimental period in cage and deep litter system. Growth performance, livability, economics and carcass characteristics were studied at the end of the experiment. Cage system had significantly (P≤0.05) higher body weight, weight gain, feed consumption, livability and better feed conversion ratio compared to birds reared under deep litter system. There was no significant (P≥0.05) difference in carcass characteristics viz., dressed weight, eviscerated weight, ready to cook weight and giblets weight of birds reared in deep litter and cage system. There was significant (P≤0.05) difference in breast meat yield in birds reared in cage compared to deep litter system. No significant (P>0.05) difference was found on cut-up and meats: bone ratio. Thus, it may be concluded that cage rearing system leads to better growth performance and carcass characteristics as compared to deep litter rearing.
