Research on the age of cattle is very important because it will determine the balance between feeding, weight gain, feed efficiency and time of finishing cattle. The purpose of this research was to investigate the effect of age on daily gain,dry matter feed intake, carcass and meat percentage of Bali cattle fed with complete feed based on corn silage. Crude protein and metabolizable energy contents of diets were 11%, and 1879.4 k calories/kg ration, respectively. The experiment used 18 heads of male Bali cattle, with three treatments and six replications. The treatments were age of the cattle: 1.5-2 years, 2.0- 2.5 years and 2.5-3 years.The cattle were housed in individual cage for three months. The results show that age of cattle had a significant effect (p<0.05) on daily gain. Average daily gain 1-1.5 years was 0.340 ± 0.041 kg/head/d, 2-2.5 years was 0.363 ± 0.032 kg/head/d and2.5-3 years that reach 0.469 ± 0.041 kg/head/d. With the increase of age, the average weight gain and feed intake also increased. The highest carcass and meat percentage was found in cattle of 2 – 2.5 years, followed by cattle of 2.5 – 3 and 1.5 – 2.0 years. The conclusion is with respect to rate of gain and feed intake, age 2.5 – 3.0 years old was the best, where-as with respect to carcass and meat percentage, age 2.0 – 2.5 years was the best.
