The results showed that acidifier supplementation in the diet at different levels improved feed intake and daily weight gain in a quadratic manner. The supplementation of organic acid improved the availability of DM, protein, organic compound and energy in the broilers at the age of 0-21 days. Comparing with the control test, the supplementation of 0.05%, 0.3% and 0.4% organic acid improved the availability of protein p
