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

“…Increasing incubation temperature at 39.5°C during 12 h/day from E7 to E16 improved the feed conversion ratio of broilers compared to the control ( Piestun et al, 2013 ; Meteyake et al, 2020 ) without affecting broilers' growth compared to 24 h/day group which had lower body weights ( Piestun et al, 2008b ). According to Tzschentke and Hall (2009) , the FCR of short-term warm stimulated broilers (38.2–38.4°C, 2 h per day, from d17 onward) was significantly lower than in broilers of the control (37.2–37.4°C) and chronic warm (38.2–38.4°C, 24 h per day, from d17 onward) incubated groups.…”

Chicken Incubation Conditions: Role in Embryo Development, Physiology and Adaptation to the Post-Hatch Environment

et al. 2022

The chicken hatching egg is a self-contained life-supporting system for the developing embryo. However, the post-hatch performance of birds depends on several factors, including the breeder management and age, egg storage conditions and duration before incubation, and the incubation conditions. Studies have determined the effect of incubation factors on chick post-hatch growth potential. Therefore, chick physical quality at hatch is receiving increasing attention. Indeed, although incubation temperature, humidity, turning and ventilation are widely investigated, the effects of several variables such as exposure of the embryo to high or low levels, time of exposure, the amplitude of variations and stage exposures on embryo development and post-hatch performance remain poorly understood. This review paper focuses on chick quality and post-hatch performance as affected by incubation conditions. Also, chick physical quality parameters are discussed in the context of the parameters for determining chick quality and the factors that may affect it. These include incubation factors such as relative humidity, temperature, turning requirements, ventilation, in ovo feeding and delay in feed access. All these factors affect chick embryo physiology and development trajectory and consequently the quality of the hatched chicks and post-hatch performance. The potential application of adapted incubation conditions for improvement of post-hatch performance up to slaughter age is also discussed. It is concluded that incubation conditions affect embryo parameters and consequently post-hatch growth differentially according to exposure time and stage of exposure. Therefore, classical physical conditions are required to improve hatchability, chick quality and post-hatch growth.

“…The adverse effect of thermal stress on livestock has been a growing global concern [ [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] ]. Thermal stress occurs when the net quantity of energy moving from the animal's body to its surroundings and the amount of heat energy generated by the animal are out of balance [ 9 ] due to fluctuations in the weather elements.…”
