Abstract: This study aimed to disclose the effects of a new compound organic acidifier mixing with L-malic acid and L-lactic acid on broiler production. A total of 1000 1-day-old Arbor acres broiler chicks were randomly divided into two treatments of 10 replicates each, with 50 birds per replicate. The feeding trial lasted for 42 days. The treatment group was offered 0.8% of the acidifier based on the control. The growth performance of the broiler chickens was improved by treatment. The broiler chickens in treatment had lower triglyceride but higher high-density lipoprotein content in serum. Superoxide dismutase activity, total antioxidant capacity and the concentrations of immunoglobulin A, complement 3 and lysozyme were increased in the serum of the broiler chickens, while the concentrations of interleukin-2 and tumor necrosis factor-α in the mucosa of jejunum were decreased by treatment. The expressions of AMPK , CD36 , FABP1 , MTTP and PPARα were increased but expressions of APOB100 and PCSK9 were decreased by treatment. In conclusion, the acidifier was effective at promoting broiler production, which was probably through the improved immunity, antioxidant and hepatic lipid metabolism capacities. The acidifier may be accelerating lipid metabolism in broiler chicken liver through regulating the expression of the genes related to fat metabolism.
