As a result, the consumption of metabolic energy reduces leading to reduced growth, decrease in egg and meat production. Birds are susceptible to heat because they lack sweet gland and their body temperature maintenance mechanisms are only efficient within the bird’s thermo-neutral zone. Heat stress is linked to changes in the birds’ behavior, respiratory and cardiovascular systems, immune function, intestinal integrity and nutrient use. In the condition of heat stress in poultry, the level of acidosis has to reduce in birds. That way, the digestive tract of a chicken will begin to show signs of weakness and force the transit of food, resulting in a significant reduction in digestion and absorption of nutrients.
