    Dietary addition of compound organic acids improves the growth performance, carcass trait, and body health of broilers by Fang Cai, Meiping Huang, Wei Liu, Xiaoling Wan, Kai Qiu, Xiao Xu

    Published 2025-01-01
    “…This study aims to evaluate the effects of this compound acidifier on growth performance, serum lipid profile, antioxidant status, and immune parameters in broilers, providing insights into its potential benefits as a dietary supplement for broiler health and productivity.MethodsA total of 240 broilers were randomly divided into four groups: a control group and three treatment groups receiving 0.25%, 0.5%, or 1.0% acidifier, with six replicates of ten birds each. Over a 6-week period, various parameters were measured, including serum triglycerides, high-density lipoproteins, lysozyme, immunoglobulins (IgA, IgM), superoxide dismutase (SOD) activity, IL-2, TNF-α, and gene expressions related to lipid metabolism.ResultsOver a 6-week period, the acidifier decreased serum triglycerides and high-density lipoproteins while also enhancing growth performance. …”
