This study was conducted to investigate the effects of various acidifiers on growth performance and nutrient digestibility of early weaned pigs. A total of 150 crossbred pigs (5.07 kg average body weight) were allotted to six treatments, which were 1) citric acid, 1.5%; 2) fumaric acid, 1.5%; 3) calcium formate, 1.5%; 4) Acidlac , 0.2%; 5) Stacidem , 0.2% and 6) control (without any acidifiers). Eighteen pigs fitted with simple T-cannulas were used to determine fecal and ileal nutrients digestibilities for two weeks. During overall experimental period, Acidlac and Stacidem treatments were significantly better than the control in feed efficiency (P＜0.05), however, in average daily gain and average daily feed intake, there was no significant difference among treatments (P＞0.05). During phase I, the fecal digestibility of protein by citric acid treatment was significantly higher than treatments supplemented with other acidifiers (P＜0.05). Acidifier treatments tended to improve ileal digestibility of dry matter when compared with control. Acidifiers seemed to improve ileal digestibilities of proximate nutrients in early weaned pigs when compared with control. During phase I, citric acid treatment was highest in fecal digestibilities of essential amino acids among treatments and was significantly higher than calcium formate treatment in fecal digestibility of isoleucine (P＜0.05). During phase II, Acidlac and Stacidem treatment showed higher fecal amino acid digestibilities than other treatments. Fecal digestibilities of valine, isoleucine, leucine and phenylalanine by Stacidem treatment was significantly higher than those of citric acid and control treatments (P＜0.05). In ileal digestibilities of total amino acids, both Acidlac and Stacidem treatments were higher than others.Pig, Acidifier, Growth performance, Nutrient digestibility
