There are now a number of companies producing feedstuffs. However, suitable selection of feedstuff for each animal to bring about economic efficiency is essential. In the implemented study, 3 types of feedstuffs, namely Hasaco, CP, T-EH, which were used for meat poultry F1 (Luong Phuong x Mia), indicated that all 3 groups of poultry fed 3 types of feedstuffs showed a high survival rate, in particular Hasaco feedstuffs benefited the highest survival rate. Hasaco was a new feed but satisfied chicken's nutrient requirement. At the end of the experiments at 12 weeks of age, feed consumption of group 1 was lowest, 752.58 g/head/day; production index at week 10 was highest; economic efficiency of group 1 was higher than that of two other groups. Difference between output and input of group 1 was 27.445 VND/kg, group 2 was 24.415 VND/kg, and group 3 was 25.445 VND/kg. This means Hasaco feedstuff of Hai Son Limited Corporation was a new feed but it brings a great result to farmers at the first step as fed chicken showed high levels of survival, high live weight, and excellent economic efficiency. For that reason, Hasaco feedstuff should be widely used.
