“…Broadly, stress is the sum of defence mechanisms or non-specific responses of an organism when it is faced with abnormal situation or extreme demands (McEwen & Akil, 2020;Sahin et al, 2009). The negative impacts of heat stress on poultry have been reported (Marchini et al, 2016;Oke, 2018;Oke et al, 2020;Olanrewaju et al, 2010;Wan et al, 2018;Yahav et al, 1997). The responses of birds to high ambient temperature includes high body temperature; lower feed intake, feed efficiency, live weight and growth and performance (Ozbey & Ozcelik, 2004).…”

“…The progress made on the improvement of some important production traits had contributed immensely to the advancement of poultry industry (Tavárez & Solis de los Santos, 2016). Today, chicken weighing 1.8 kg can now be produced by the broiler industry in 6–7 weeks (Maurer, 2003; Oke et al., 2020). As a result of this advances, several strains of broilers with different physiology or growth trajectories, or both, have been developed (Tona et al., 2003).…”

“…The growth rate of commercial broiler chickens is fast and they are able to reach market weight of two kilogram and above at about seven weeks of age or less (Smith, 1990; Tallentire et al., 2016). However, optimal growth of the birds can only take place when the birds are reared under a thermoneutral zone of 18°C–24°C (Charles, 2002; Oke et al., 2020; Olanrewaju et al., 2010). Indeed, harsh environmental conditions circumscribe the growth potential of the birds (De Basilio et al., 2001; Sohail et al., 2012).…”

There has been an unprecedented increase in global animal production, especially in subtropical and tropical areas in the last two decades (Renaudeau et al., 2012). The increase in the demand for food is due to a rise in human population (Godfray et al., 2010). Due to its potential role to provide food and livelihood securities (Paswan et al., 2014), poultry production, especially broiler production, are expected to meet the critical shortage in animal protein needed by Africa (Hatab et al., 2019).There has been growing concerns on the impacts of climate change on livestock production. For example, in West Africa, the expected increase in average temperature by 2°C-6°C by the year 2100 (Sylla et al., 2016) portends a serious challenge to sustainable broiler production. Due to the climatic challenge, heat stress events are expected to become more frequent in livestock species (Rahimi et al., 2020). A study by Tawfeek et al. (2014) showed that high ambient temperature adversely affected the performance of broiler chickens under high ambient temperature. However, the authors indicated that supplementation of antioxidants ameliorated the effects of thermal stress on the birds. Therefore, the diets of the birds are required to be adjusted to the climatic conditions (Attia & Hassan, 2017;Nir, 1992;Suganya et al., 2015) and also to the prevailing economic status of the countries where they are produced.The fast rate of development of the poultry production in tropical countries has also engendered a situation of overdependence on

Climate change has emerged as a significant occurrence that adversely affects broiler production, especially in tropical climates. Broiler chickens, bred for rapid growth and high meat production, rely heavily on optimal environmental conditions to achieve their genetic potential. However, climate change disrupts these conditions and poses numerous challenges for broiler production. One of the primary impacts of climate change on broiler production is the decreased ability of birds to attain their genetic potential for faster growth. Broilers are bred to possess specific genetic traits that enable them to grow rapidly and efficiently convert feed into meat. However, in tropical climates affected by climate change, the consequent rise in daily temperatures, increased humidity and altered precipitation patterns create an unfavourable environment for broilers. These conditions impede their growth and development, preventing them from reaching their maximum genetic influence, which is crucial for achieving desirable production outcomes. Furthermore, climate change exacerbates the existing challenges faced by broiler production systems. Higher feed costs impact the industry's economic viability and limit the availability of quality nutrition for the birds, further hampering their growth potential. In addition to feed scarcity, climate change also predisposes broiler chickens to thermal stress. This review collates existing information on climate change and its impact on broiler production, including nutrition, immune function, health and disease susceptibility. It also summarizes the challenges of broiler production under hot and humid climate conditions with different approaches to ameliorating the effects of harsh climatic conditions in poultry.
