“…Considering the constraints of SNP arrays and the reduction of DNA sequencing costs, NGS-based WGS approach is now the most popular tool to infer the evolutionary history of chicken genomes, to assess the genetic diversity and population genetic structure at regional, continental, and global scales, to identify the genetic controls of specific traits of interest, and to screen for the signatures of selection for productive traits and environmental adaptation [Rubin et al, 2010;Mugal et al, 2013;Wang MS et al, 2015, 2016a, 2016bGuo X, , 2022Guo Y et al, , 2021Zhang et al, 2016Zhang et al, , 2022Li D et al, , 2019Boschiero et al, 2018;Derks et al, 2018;Lawal et al, 2018Lawal et al, , 2020Sohrabi et al, 2018;Almeida et al, 2019;Talebi et al, 2020;Tiley et al, 2020;Wang Q et al, 2020;Gheyas et al, 2021Gheyas et al, , 2022Li YD et al, 2021;Mariadassou et al, 2021;Rostamzadeh Mahdabi et al, 2021;Tan et al, 2021;Yang Z et al, 2021;Asadollahpour Nanaei et al, 2022;Chen X et al, 2022;Gao et al, 2022;Geibel et al, 2022;Li Y et al, 2022;Sun et al, 2022;Wang S et al, 2022;Xu et al, 2022;Yuan J et al, 2022;Zeng et al, 2022].…”

Heat stress results in significant economic losses to the poultry industry. Genetics plays an important role in chickens adapting to the warm environment. Physiological parameters such as hematochemical parameters change in response to heat stress in chickens. To explore the genetics of heat stress resilience in chickens, a genome-wide association study (GWAS) was conducted using Hy-Line Brown layer chicks subjected to either high ambient temperature or combined high temperature and Newcastle disease virus infection. Hematochemical parameters were measured during three treatment phases: acute heat stress, chronic heat stress, and chronic heat stress combined with NDV infection. Significant changes in blood parameters were recorded for 11 parameters (sodium (Na+, potassium (K+), ionized calcium (iCa2+), glucose (Glu), pH, carbon dioxide partial pressure (PCO2), oxygen partial pressure (PO2), total carbon dioxide (TCO2), bicarbonate (HCO3), base excess (BE), and oxygen saturation (sO2)) across the three treatments. The GWAS revealed 39 significant SNPs (p < 0.05) for seven parameters, located on Gallus gallus chromosomes (GGA) 1, 3, 4, 6, 11, and 12. The significant genomic regions were further investigated to examine if the genes within the regions were associated with the corresponding traits under heat stress. A candidate gene list including genes in the identified genomic regions that were also differentially expressed in chicken tissues under heat stress was generated. Understanding the correlation between genetic variants and resilience to heat stress is an important step towards improving heat tolerance in poultry.

This experiment was conducted in the animal production field of the Agricultural Research Station/College of Agriculture and Marshlands/Dhi Qar University for the period from (30/11/2022 to 4/1/2023) for the purpose of studying the gene expression of the HSP 70 heat shock gene when ascorbic acid was added to the diets provided to birds. And the extent of its effect on the quality of meat. In this study, 150 non-sexed Ross 308 birds, one day old, were used in this study. The study included four treatments. Incubation was randomly distributed among the experimental treatments, with three replicates of 12 replicated birds. The treatments were divided on the basis of adding ascorbic acid to the diet without adding it, as well as shedding heat by 2-3 m for a period of 8 hours / day at the normal temperature rate and without heat shedding. The division of treatments began immediately after the second week of the age of the birds. The gene expression level of the HSP70 gene was measured at the age of 21 and 35days, and the sensory evaluation test of the thigh and chest segments was measured at the age of 21. and 35 days The results of the study showed the: 1-The high rate of gene expression of the HSP70 gene in the liver tissue in the T2 treatment exposed to a high temperature negatively affected the quality of meat through conducting a sensory evaluation of the thigh and breast segments, where the evaluation rate decreased in this treatment, which indicates that the relationship is inverse between the rate of the gene HSP70 and average sensory evaluation of the thigh and thoracicseg ments. 2-Adding ascorbic acid at a rate of 1 gm / kg feed to the T4 treatment that was also exposed to high temperature erecorded an increase in the sensory evaluation rate of the thigh and breast segments, which led to an improvement in flavor, taste and tenderness in poultry meat, which indicates that the addition of ascorbic acid has a role in relieving stress Thus decreased, the rate of gene expression of the HSP70 gene.
