An evaluation of the thermoregulatory potential of in ovo delivered bioactive substances (probiotic, folic acid, and essential oil) in broiler chickens

The role of phytogenic feed additives in stress mitigation in broiler chickens

“…Avians are more vulnerable to a harsh temperature than other animals as they do not possess sweat glands and are covered with thick feathers, which prevent easy heat loss from their bodies to the environment (Loyau et al, 2013; Uyanga et al, 2022), causing them to be susceptible to thermal stress, which is one of the greatest environmental problems facing chicken farmers, particularly in the tropics (Ajayi et al, 2022; Kpomasse et al, 2021; Oke et al, 2022; Oke, Uyanga, et al, 2021). Studies have demonstrated that poultry under heat stress exhibits poorer growth performance, productivity indices, metabolism, immunity, behaviour, well‐being and physiological responses (Meteyake et al, 2020; Oladokun et al, 2023; Uyanga et al, 2023). To ensure sustainable poultry production, it is imperative to explore viable means of mitigating the impact of heat stress on avian species.…”

“…There has been a growing interest in the use of phytogenic feed additives (PFA) in recent years. Several studies have indicated that the bioactive compounds in PFA are beneficial in mitigating stress in birds (Liu et al, 2014; Mehdi et al, 2018; Oladokun et al, 2023). This review discusses the various roles of different PFA in mitigating stress in poultry production.…”
