%X The aim of the experiment was to investigate the productive and reproductive potential of pregnant Red Chittagong (RC) cows through improved feeding. A total of 30 pregnant RC cows from each of 30 farmers having six months pregnancy and between 2 and 3 parities old were used in the trial. The cows were randomly allocated to three dietary treatment groups, i.e., T0, T1 and T2. The cows of T0 group received farmers¡¯ diet (63% of dry matter intake of cows according to ARC, 1995) without the supplementation and served as control. The cows of T1 group received farmer¡¯s diet (63%) plus 25% supplementation of formulated concentrate diet for deficit of requirement of cows {(63 + 9.25) = 72.25% dry matter intake of cows according to ARC, 1995)} and T2 group received farmers diet (63%) plus formulated concentrate diet to meet 100% requirements of cows according to ARC (1995) {(63% +37%) = 100%}. The total live weight gain before calving of RC cows were observed significantly (P <0.05) higher in T2 and T1 groups than T0 group. The calves birth weight was found significantly (P <0.05) higher in T2group than T1 and T0 groups. The gestation length was increased approximately 3 and 2 days for T2 and T1 groups, respectively, compared to T0 group. Therefore, the farmer¡¯s diet plus supplementation of formulated concentrate diet to meet 100% requirement of cows according to ARC (1995) {(63% +37%) = 100%} was a better improved feeding system of pregnant Red Chittagong cows
