“…In this study, an elevation in mRNA transcription of the UCP gene was detected in birds reared under high ambient temperature compared with the thermoneutral group. In the same line, Dridi et al (2008) and Radwan et al (2018) demonstrated an upregulation of the UCP gene in the muscle of broilers maintained at high ambient temperature. Under high temperature, the UCP mRNA expression increases to provide the energy needed for the panting process, which in turn helps the birds to lose the excess heat (Del Vesco and Gasparino 2013).…”

The current study was conducted to investigate the impact of thermal stress on growth performance, blood biomarkers, metabolic hormones, immunological response, antioxidant activity, and expression of stress-related genes in broilers. One hundred and fifty one-day-old chicks (Ross 308) were utilized in this work. On the 21st day of age, birds were subjected to three environmentally controlled treatments with five replicate pens of 10 birds per each, representing an initial density of 10 birds/m 2 -control: reared in a thermoneutral condition; THS 1 and THS 2: exposed to 4 and 6 h of daily thermal stress at 40 ± 1°C, respectively, until the 42 days of age. The results demonstrated that thermal stress for 4 and 6 h significantly reduced (P < 0.001) daily weight gain, daily feed intake, blood leukocyte and lymphocyte counts, serum immunoglobulins (IgM, IgA, IgG), and insulin-like growth factor-1 (IGF-1), while serum levels of aspartate aminotransferase, alanine aminotransferase, glucose, cholesterol, low-density lipoprotein, and lactate dehydrogenase were elevated relative to the thermoneutral group. Additionally, the corticosterone level and the ratio of heterophil:lymphocyte increased significantly (P < 0.001) in thermal-stressed groups. The antioxidant enzymes were affected by thermal stress as represented by a significant decrease in the activity of serum catalase (CAT) and glutathione peroxidase (GSH-Px) along with an increase in malonaldehyde concentration. Thermal stress affected gene expression by upregulating heat shock protein 70, heat shock factors 1 and 3, nuclear factor kappa B, interleukin-4, and uncoupling protein, and downregulating GSH-Px, CAT, and IGF-1 transcript levels. However, no changes were observed in interleukin-2 expression levels. It can be concluded that thermal stress destructively influences productivity, physiological status, and gene expression by upregulating heat shock protein 70, heat shock factors 1 and 3, nuclear factor kappa B, interleukin-4, and uncoupling protein, and downregulating GSH-Px, CAT, and IGF-1 transcript levels of broiler chickens.

“…Thes results reflected better hybrid vigor when used RIR with Sinai (RI XSI crosses and also the reciprocal SI X RI) due to RIR and Sinai benefited the heaver body weight compared to Fayoumi one. Under heat condition, RIR affical more its body weight depressed compared to Sinai line (Radwan and Mahrous 2018). They also observed under these circumstances Sinai line achieved better adaptation than RIR one and produced more level HSP90 and these preferable trait inherited to next generations.…”

“…The heat stress was negative major effect of economic traits such as body weight, growth rate, feed efficiency, meat yield , susceptibility to disease and mortality percentage (Amrutkar et al, 2014;Lowman et al, 2014 ). Some researcher had studed effect heat stresse for muscle development and estimated gene expression responsible for this (Radwan et al, 2018); who reached that decrease gene expression of both Myogenin and UCP genes reflected that growth muscle and depression carcass weight.…”

A crossbreeding experiment was executed between three breeds were selected three generation for heavy body weight under high temperature condition Sinai (SI) and Rhode Island Red (RI) and Fayoumi breeds. 900 crossing meals from each genotype were recorded singular body weight and body weight gain at hatch, 4, 8 and 12 weeks of age. crosses SI XRI and reciprocal RI x Si significant heaver body weight and body weight gain compared than other crosses and pure breed. On the other hand body weight and body weight gain were significant heaver for pure line Sinai or Rod iland read and crosses SI x F, F x RI, Fx SI and RI xF compared to Fayoumi pure line. Heterosis was positive significant on body weight at hatch, 4,8 and 12 weeks of ages. As the same trend results of body weight gain but, negative significant at the intervals from 4wks to 8wks only. It could be observed that the hybrid vigor of body weight was significant positive effect for crosses SI X RI and reciprocal crosses RI XSI and RI XF ones. While, the hybrid vigor of body weight gain was significant positive effect for all diallel crossing except F X RI crosses. the direct additive effects were negative for line Fayoumi both body weight and weight gain taits at diferent age of these study. But these reciprocal effect were significant positive for Sinai and Rodiland red lines both body weight and body weight gain. These resuls shown that the croses RI XSI beter than SI X RI for both body weight and body weight gain. Maternal effect of body weight and body weight gain were significant positive effect at hatcher , for FF and SI SI. While, it was significant negative effect for RIRI. On the other hand, were significant positive for body weight at hatcher and 4 weeks of age only. While, maternal effect was significan positive at the intervals 0-4weeks only. The last shown that the maternal effect had a play essential role on body weght and body weight gain. Recommended used crosses Sinai and rod Iland red to produce commercial meat strains in hot climated countery.

The objective of this study was to estimated gene expression in breast muscles of two broiler strains with used to Myoustatin gene in marketing age (5 weeks of age) under heat stress and compared to control group for 1 hour daily for 7 days in Shalakan farm of Faculty of Agriculture, Ain Shams University, broiler chicks (150 chicks in each strains) of 1 day of age were used in this study. So, the measurements were taken (respiratory rate, rectal temperature and estimated gene expression). The results obtained the gene expression of Myostatin gene in muscle breast was observed highest in Ross strain compared with Indian River strain under heat stress, but no different between strains ( Ross and Indian River) in control group. However, respiratory rate of Ross and Indian River under heat at 5 week of age showed that the Indian River strain was high significant at 5 week of age compared to Ross ones. As shown that rectal temperature of Ross and Indian River were a high significant effect of treatment (heat group was higher from control group) and not a significant of strain.The present experiment was conducted to estimated gene expression on meat quality traits of different tropical stress conditions in different broiler strains during 7 days and 5 weeks of age. Introgressions some major genes likes myostatin gene in muscle breast into broiler improve under the heat stress.
