摘要：This study was undertaken with a view to determining the effect of partial green grass over dry feeding on the productive performance of early lactating crossbred cows. With that understanding, fifteen early lactating crossbred cows having nearly similar body weight, body condition score, milk yield and stage of lactation were selected and divided into three groups composed of five in each group (A, B and C group). Cows of A group received 2 kg concentrates without green grass daily. Group B and C received daily 1.85 kg conc. + 3 kg green grass and 1.75 kg conc. + 6 kg green grass respectively along with ad libitum straw for each cow of all groups. Daily feed intake were recorded. Live weight changes of cows were measured fortnightly and condition scores were measured before starting and at the end of the experiment. Milk composition (fat, SNF, protein and ash) as percentage were determined monthly. The average daily DM intake were 7.07±0.12, 7.16±0.03 and 7.78±0.04 kg for A, B and C group, respectively. This study showed that the DM intake, live weight gain, body condition score, milk yield and milk composition in respect of fat, SNF and protein were significantly (p<0.01 and p<0.05) higher in C group followed by B group and lowest values obtained in A group. Considering the present research, it would be fair to conclude that the partial green grass over dry feeding showed the positive effect on the productive performance of early lactating crossbred cows.
