“…The mortality rate in the present study (30.96%) was lower than that reported (47.2%) by Ritonga (2016). Embryo mortality can be influenced by several factors, including the age of the egg, temperature and humidity of the hatching machine (Ningtyas et al 2013;Iraqi et al 2024) egg weight, egg shape index, storage period (Dey et al 2019) breeder flock age, setter, hatcher type and genotype (Grochowska et al 2019) and handling of the eggs during hatching (Wicaksono et al 2013;Ozl et al 2021). Higher mortality rate (65.83%) has also been reported by Agustira and Yayuk (2017) which could be due to more storage time of hatching eggs as Agustira and Yayuk (2017) stored eggs for nine days while in the present it was only five days.…”

“…Fluctuations in temperature during the post-hatching developmental period can significantly disrupt and modify the developmental trajectory of the chick ( Yalcin et al, 2017 ). The occurrence of elevated temperatures beyond the optimal range has been observed to induce hyperthermia and dehydration in chicks, leading to heightened mortality rates ( Patrone et al, 2023 ; Iraqi et al, 2024 ), diminished feed intake, and hindered growth progression ( Sumanu et al, 2022 ). Additionally, research has demonstrated that a 4-d period of heat stress leads to reduced weight gain, feed intake, and feeding efficiency, as well as elevated rectal temperature, diminished hepatic IGF1, and decreased mRNA expression for pituitary adrenocorticotropic hormone in chicks ( Okuyama et al, 2017 ).…”
