Effect of environmental cooling on certain biochemical responses in broilers

P Datta, P C Gangwar

    Acta Physiologica Et Pharmacologica Bulgarica
    |January 1, 1981
    PubMed
    Summary

    Broiler chickens exposed to hot and humid conditions experience significant stress. Evaporative cooling methods, like foggers and coolers, effectively reduce this stress, leading to better growth and higher ascorbic acid levels.

    Area of Science:

    • Animal Science
    • Poultry Science
    • Environmental Physiology

    Background:

    • High temperatures negatively impact broiler growth and well-being.
    • Understanding thermal stress mitigation is crucial for efficient poultry production.

    Purpose of the Study:

    • To evaluate the impact of different cooling systems on broiler growth attributes.
    • To assess the effectiveness of cooling in reducing heat stress in broilers.

    Main Methods:

    • Broiler chicks were housed in control, fogger, exhaust fan, and cooler environments.
    • Blood cholesterol and ascorbic acid levels were measured during hot and dry/humid periods.

    Main Results:

    • Control and exhaust fan groups showed higher blood cholesterol, indicating stress.
    • Cooler groups exhibited lower cholesterol and higher ascorbic acid levels.
    • Higher ascorbic acid correlated positively with heavier body weights in cooler groups.

    Conclusions:

    • The hot and humid period in Ludhiana is highly stressful for broilers.
    • Evaporative cooling is an effective strategy for alleviating heat stress in poultry.
    • Cooling systems improve broiler resistance to thermal stress and enhance growth.
