“…However, it is unknown whether a LPD supplemented with Ile promotes growth performance and meat quality. In the present study, growth performance was depressed in broilers fed a LPD, similar to a report by Liu et al (2022) . However, Ile supplementation significantly improved growth performance of broilers fed a LPD, partially in agreement with a previous study that reported significantly increased ADG and decreased F:G of broilers fed a diet supplemented with Ile ( Corrent and Bartelt, 2011 ).…”

“…Enhanced fecal excretion contributes to transient heat loss ( Saeed et al ., 2019 ); however, excreta also reduce litter quality, result in a high-moisture environment, and compromise microbial composition. HS was found to reduce nitrogen efficiency and excretion, while increasing moisture, pH, and uric acid in excreta ( Liu et al ., 2022a ). Higher litter moisture favors the proliferation of bacteria ( Dumas et al ., 2011 ) and induces footpad dermatitis in floor-reared chickens ( Taira et al ., 2014 ).…”

Poultry meat and egg production benefits from a smaller carbon footprint, as well as feed and water consumption, per unit of product, than other protein sources. Therefore, maintaining a sustainable production of poultry meat is important to meet the increasing global demand for this staple. Heat stress experienced during the summer season or in tropical/subtropical areas negatively affects the productivity and health of chickens. Crucially, its impact is predicted to grow with the acceleration of global warming. Heat stress affects the physiology, metabolism, and immune response of chickens, causing electrolyte imbalance, oxidative stress, endocrine disorders, inflammation, and immunosuppression. These changes do not occur independently, pointing to a systemic mechanism. Recently, intestinal homeostasis has been identified as an important contributor to nutrient absorption and the progression of systemic inflammation. Its mechanism of action is thought to involve neuroendocrine signaling, antioxidant response, the presence of oxidants in the diet, and microbiota composition. The present review focuses on the effect of heat stress on intestinal dysfunction in chickens and the underlying causative factors. Understanding these mechanisms will direct the design of strategies to mitigate the negative effect of heat stress, while benefiting both animal health and sustainable poultry production.
