The study was conducted to find out the effect of beef cattle diet on the performance of upgraded Shahiwal bulls at Bangabandhu Academy for Poverty Alleviation and Rural Development (BAPARD) cattle farm in Gopalganj. For this purpose, twelve local x Shahiwal upgraded bulls (L×SH) of average 19 months of age and 169 kg live weight were divided into three equal groups. Three different rations such as: a mixed concentrate ration (T 1 ), mixed concentrate ration and urea molasses straw (UMS) at a ratio of 1:1 on dry matter basis (T 2 ) and green grass (pakchong) based ration without concentrate and UMS (T 3 ) were selected for this experiment. Upgraded bulls were randomly distributed into 3 groups for 3 above different rations. The results found that the average daily live weight gains of three groups was 320g, 315g and 314g respectively, which were not differ significantly (P<0.05). Daily DM intake was significantly higher in T 3 (8.1 g/head/day) compared to T 1 and T 2 (P<0.05), but the digestibility found lower than other treatments. Feed conversion ratio (FCR) was significant higher in T 1 (2.63) but interestingly, cost of per kg live weight gain was the lowest in T 3 (85 BDT) compared to other two treatments (P<0.05). Therefore, considering the above factors, it might be stated that a beef ration only with green grass would be the appropriate diet for the floodplains area for local x Shahiwal upgraded bulls.

The study was conducted to find out the study of grass based ration for cattle fattening of upgraded Holstein Frisian bulls at BAPARD cattle farm in Gopalganj. For this purpose, twelve local × Study of grass based ration for cattle fattening of upgraded Holstein Friesian bulls of average 21.39 months of age and 272.78kg live weight were divided into four equal groups. Three different rations such as: a mixed concentrate ration (T1 ), mixed concentrate ration and green grass at a ratio of 1:1 on dry matter basis (T2 ) and green grass only (pakchong) based ration without concentrate and green grass (T3 ) were selected for this experiment. Upgraded bulls were randomly distributed into three groups for three above different rations. The results found that the average daily live weight gains of three groups was 550g, 457g and 480g respectively, which were not differed significantly (P>0.05). Daily DM intake was significantly higher in T3 (9.86g/head/day) compared to T1 and T2 (P<0.05), but the digestibility found lower in T2 than other treatments. Feed conversion ratio (FCR) was significantly higher in T3 (9.86) but interestingly, cost of per kg live weight gain was the lowest in T3 (209.53 BDT) compared to other two treatments (P<0.05). Considering the above findings, a beef ration only with green grass would be the appropriate diet for the south-west area of Bangladesh for local × Holstein Frisian upgraded bulls.
