“…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.…”

This study aims to determine the hatching performance of Kokok Balenggek chicken (KBC) using different males as the formation of superior local meat-type chickens. The study used an experimental method, randomized block design (RBD), with eight treatments and three groups. The treatment was male KBC (G0) and the group was the hatching period. Chickens are mated using Artificial Insemination (AI) with a sex ratio of 1:5. A total of 594 KBC egg were selected. The variables of this study consisted of fertility rate (FR%), embryonic mortality (EM%), hatchability of fertile egg (HRF%), and day-old chick (DOC) viability. Data were analyzed using Minitab version 19. The results of the study showed that individual differences in males had non-significant (P>0.05) effect on FR, EM, HRF and DOC viability. The average FR was (73.38%), EM (30.96%), HRF (69.04%) and DOC viability (90.73%). The macroscopic examination of KBC-G0 semen indicated volume as 0.31±0.11mL, consistency to be thick creamy with a milky white color and pH as 7.35±0.17. The microscopic examination of KBC-G0 semen indicated average ++ mass movement and sperm motility, viability and abnormality of spermatozoa to be 71. 25±8.35, 78.34±6.22 and 11.67±2.90%, respectively whereas concentration of spermatozoa was 210.46±43.68 x 10 7 sperm/mL spermatozoa. In conclusion, the eight males KBC have the same and good hatching performance so can be used as males to produce KBC (G1) in the formation of superior local meat type chickens.

“…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 ).…”

“…Researchers and producers need to persistently search for improved methods to tackle these detrimental alterations. Thermally manipulated fertile eggs during incubation (a critical developmental period for embryos), especially from the 12 th to the 18 th days, have been shown to improve growth performance and reduce the negative impacts of post-hatch heat stress by enhancing thermotolerance acquisition [ 2 , 4 ]. Early heat acclimation during pre- or postnatal development can epigenetically regulate gene expression and create long-term physiological memory for improved thermotolerance [ 2 , 11 , 12 ].…”

Background and Aim: The management of incubation conditions impacts embryonic development, hatchability, and post-hatch performance. This study aimed to examine the effects of thermal manipulation (TM) during embryonic development on roosters’ thermotolerance, antioxidant activity, immunity, and semen quality under heat-stress conditions. Materials and Methods: 1200 fertile eggs were distributed evenly between two groups, each containing three replicates (200 eggs/replicate). The first group (G1) was held in the commercial setter with a consistent temperature of 37.5°C and 55% relative humidity (RH) through the 18-day incubation period, acting as a control, while the second group (G2) experienced these conditions until only the 11th day. The eggs were incubated at 39.5°C with 60% RH for 4 h each day from the 12th to the 18th day. From the 19th to 22nd incubation days, both groups maintained a consistent temperature of 37.2°C with a RH of 70%. Two hundred hatched male chicks per treatment group were moved into a closed-system house. All roosters were exposed to a 6-h daily heat challenge with a temperature of 35°C and a humidity of 70% between their 36th and 40th weeks of age. Results: Roosters of G2 exposed to thermal challenge showed improvements (p ≤ 0.05) in multiple blood biochemical, antioxidant, and immunity markers, including total protein, globulin, aspartate aminotransferase, alanine aminotransferase, triiodothyronine, thyroxine, corticosterone, testosterone, total antioxidant capacity, malondialdehyde, immunoglobulin G, immunoglobulin M, and immunoglobulin A levels. Improved semen quality characteristics, including ejaculate volume, sperm concentration, motility, livability, and quality factor, as well as enhanced thermoregulation in post-hatch cocks, were also achieved (p ≤ 0.05). Conclusion: To boost antioxidant activity, immunity, thermotolerance, and semen parameters in roosters under heat-stress conditions, TM application during egg incubation, specifically at 12–18 days, is recommended. Keywords: antioxidant capacity, immunity, incubation temperature, semen characteristics, testosterone, thermotolerance.
