Heat stress causes several physiological changes, such as oxidative stress, acid-base imbalance, and suppressed immunocompetence, which leads to increased mortality and reduced feed efficiency, body weight, feed intake, and egg production, and also affects meat and egg quality.

Heat stress in poultry significantly impacts their physiology by causing oxidative stress, acid-base imbalance, suppressed immune function, and altered metabolic processes, leading to reduced feed intake, body weight gain, egg production, and ultimately, increased mortality; to mitigate these effects, management strategies include improving ventilation, cooling systems, adjusting feed composition with added vitamins and electrolytes, providing access to cool water, and selecting heat-tolerant breeds when possible

Heat stress elicits physiological, behavioral, and production changes in poultry.
-
Heat stress in poultry increases body temperature, panting, and dehydration while reducing feed intake, immunity, and productivity, but can be managed through ventilation, cooling systems, electrolyte supplementation, and proper hydration.

Increased body temperature, elevated heart rate,reduce Feed intake and feed conversion ratio.
-
Increased body temperature, elevated heart rate, altered hormone levels, oxidative stress, acid-base imbalance, suppressed immune response, impaired digestion, and disruption of electrolyte balance
-
Heat stress in poultry disrupts various physiological parameters, leading to decreased growth, reduced egg production, and impaired immune function, while management strategies like improved ventilation, cooling systems, and nutritional adjustments can mitigate these negative impacts.
