    This study looked into how broilers were affected by a novel compound organic acidifier that contained L-lactic, L-malic and acetic acids. Two hundred and forty broilers were split up into four groups: a control group, three treatment groups that received 0.25%, 0.5%, or 1.0% acidifier, and six duplicates of ten birds each. Over a 6week period, the acidifier decreased serum triglycerides and high-density lipoproteins while also enhancing growth performance. Additionally, it raised the serum levels of lysozyme, IgA, IgM, and the SOD. Additionally, IL-2 and TNF-α concentrations in the jejunum mucosa decreased. The acidifier upregulated PPARα, AMPK, FABP1 and MTTP expressions, and downregulated APOB100. Overall, the acidifier effectively improved broiler growth performance during the early development phase primarily by enhancing hepatic lipid metabolism, antioxidant capacity, and immune function. These results suggest that the acidifier may accelerate liver lipid metabolism in broilers by modulating the gene expression profiles involved in lipid metabolism.
