This study establishes reference values for nine key blood constituents in broilers. Age and season significantly impact these values, providing insights into poultry health management.

Area of Science:

  • Veterinary Hematology
  • Avian Physiology

Background:

  • Establishing accurate reference ranges for broiler blood parameters is crucial for health monitoring.
  • Variations in age, strain, sex, and season can influence these hematochemical values.

Purpose of the Study:

  • To define reference values for nine blood constituents in broilers.
  • To identify factors influencing these hematochemical variables.

Main Methods:

  • Analysis of 800 broilers from 20 commercial farms.
  • Grouping broilers by age (21, 45 days), strain (Arbor Acres, Hybro), sex, and season (summer, winter).
  • Computation of reference limits using .975 and .025 fractiles.

Main Results:

  • Age and sampling season were the primary factors influencing hematochemical values.

  • Interactions between age and strain, and age and season, significantly affected various blood constituents.
  • Established reference limits for total proteins, albumin, cholesterol, triglycerides, AST, ALP, calcium, and phosphorus.

    • Conclusions:

    • Defined reference limits can serve as indicators of metabolic and health status in poultry farms.
    • Understanding the influence of age, season, and strain is vital for accurate broiler health assessment.
