Development of productive and reproductive potential of pregnant Red Chittagong cows through improved feeding in small scale dairy farm

Abstract

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.
