Abstract

Twelve indigenous(desi) growing male calves of 9-12 months of age($95.3{\pm}12.6kg$) were divided into 4 groups having 3 animals in each group. Each group of calves received 1 kg fresh concentrate mixtures where tea waste was supplemented as 0($T_0$), 50($T_1$), 100($T_2$) and 150($T_3$) g $d^{-1}$ with the replacement of equal amount of concentrate mixtures. In addition, each calf received ad libitum chopped rice straw and 2 kg green grass a day. Dry matter intake increased by offering higher levels of tea waste except in the treatment $T_3$. Daily gain(g $d^{-1}$) was comparatively higher in $T_2$ group(314.6g) compared to other treatments. Feed efficiency(kg DM $kg^{-1}$ gain) was also higher in $T_2$ group(9.9) where feed cost $kg^{-1}$ gain was also comparatively lower(Tk. 25.7) than the other treatments. Dry matter and CP digestibility increased with the increase in supplementation of tea wastes except in the treatment $T_3$.
