Immune function of Chinese formula Qingwen Baidu granule in broilers

Area of Science:

• Veterinary Immunology
• Poultry Science
• Pharmacology

Background:

• Broiler immunity is crucial for disease prevention and productivity.
• Assessing the impact of herbal preparations on poultry immune systems is an area of interest.
• Newcastle Disease remains a significant threat to poultry health.

Purpose of the Study:

• To investigate the effects of Qingwen Baidu granules on broiler immunity.
• To evaluate the impact on antibody levels, immune organ indices, and lymphocyte transformation.
• To determine the efficacy of Qingwen Baidu granules in enhancing chicken immune function.

Main Methods:

• Hy-line variety white cocks (30 days old) were used.
• Antibody titers for Newcastle Disease were measured.
• MTT assay determined T lymphocyte proliferation.
• Immune organ indices (bursa, thymus, spleen) were measured via organ weighing.

Main Results:

• Qingwen Baidu granules prolonged residue time and improved lymphocyte conversion ratio.
• Significant increases in bursa, thymus, and spleen indices were observed.
• Enhanced immune organ development and growth were noted.

Conclusions:

• Qingwen Baidu granules improve serum antibody levels and peripheral blood lymphocyte proliferation.
• The granules enhance cellular immune function and elevate immune organ indices.
• Qingwen Baidu granules effectively potentiate both cytoimmunity and humoral immunity in broilers.
