    Area of Science:

    • Animal Science
    • Poultry Science
    • Agricultural Engineering

    Background:

    • Broiler performance is sensitive to environmental temperature fluctuations.
    • Optimizing temperature cycles is crucial for maximizing growth and feed efficiency in poultry production.
    • Summer heat stress can negatively impact broiler health and productivity.

    Purpose of the Study:

    • To investigate the effect of reduced low-cycle temperatures on broiler performance during summer.
    • To determine if a cooler nighttime temperature benefits broiler growth.
    • To establish optimal thermal management strategies for commercial broiler operations.

    Main Methods:

    • Five trials were conducted using commercial male broilers.
    • Broilers were subjected to 24-hour linear temperature cycles.
    • Temperatures ranged from a high of 35°C to a low of either 26.7°C or 21.1°C.

    Main Results:

    • Lowering the low portion of the temperature cycle from 26.7°C to 21.1°C significantly increased broiler body weight.
    • Broilers exposed to cooler nighttime temperatures exhibited enhanced growth by 48 days of age.
    • The results indicate a positive correlation between reduced low-cycle temperature and improved broiler weight gain.

    Conclusions:

    • Reducing the minimum ambient temperature during the 24-hour cycle can enhance broiler performance.
    • Implementing cooler nighttime temperatures is a viable strategy to improve broiler body weight in summer conditions.
    • Further research into precise temperature thresholds may optimize broiler production efficiency.
