“…Although it has been shown that Gln has a positive effect in alleviating heat stress, there is little research on the relationship between Gln and HSP70 expression in broilers under high temperature conditions [23]. Therefore, in this study, we determined whether Gln can enhance the anti-oxidative stress ability of the breast muscle by increasing the expression of antioxidant genes and HSP70 in broilers exposed to cyclic heat stress.…”

This study investigated whether Glutamine (Gln) could be used as an additive to improve antioxidant capacity in the breast muscle of heat-stressed broilers. Two hundred and forty 22-day-old Arbor Acres broilers in the G1, G2, G3, and G4 groups (n = 60 each) were housed in a cyclic hot environment and fed the basal diet with 0%, 0.5%, 1.0%, and 1.5% Gln, respectively. Compared with the G1 group, dietary 1.5% Gln increased (p < 0.05) pH and b* values, but decreased (p < 0.05) L* cooking loss, drip loss, and water loss rate in breast meat of heat-stressed broilers. Malondialdehyde levels in the breast muscle were lower (p < 0.05) in 1.0% and 1.5% Gln groups than that of the heat-stress group. Compared with the G1 group, dietary 1.5% Gln increased (p < 0.05) catalase (CAT), glutathione, glutathione peroxidase (GSH-Px,) and total antioxidant capacity in the breast muscle of heat-stressed broilers. Furthermore, the CAT, GSH-Px, HSP70 mRNA expression levels, and HSP70 protein expression levels were increased (p < 0.05) in the G3 and G4 groups compared with the G1 group. In sum, Gln alleviated antioxidant capacity and lipid peroxidation in the breast muscle of heat-stressed broilers through antioxidant genes and HSP70 pathways.

“…Glutamine dietary supplementation decreases health problems, prevents intestinal atrophy, maintains antioxidant status, decreases incidence of diarrhea, resulting in increased weight gain and improved efficiency (Haynes et al, 2009;Zhong et al, 2011;Wang et al, 2014;Watford, 2015). Similar results have also been reported in broiler chicken (Nassiri Moghaddam and Alizadeh-Ghamsari, 2013;Jazideh et al, 2014;Nascimento et al, 2014;Manvailer et al, 2015;Muro et al, 2015;Olubodun et al, 2015;Ribeiro Jr et al, 2015;Luquetti et al, 2016;Maiorka et al, 2016;Namroud et al, 2017).…”

After a collaborative and uninterrupted work, the UPS has continued to improve one more year as a Research University, and has gone from the position 6,611 in the world and 13 in Ecuador (Webometrics, 2013) to the position 2627 (Webometrics, 2020) worldwide, it is the 170 on the continent and 7 in Ecuador. The continuous improvement of all teams and the strategic vision have made progress in the World Ranking, allowing to go to 3984 positions in 7 years and 366 new positions compared to 2019. Within this global strategy of improvement of the UPS as a Research University, LA GRANJA, belonging to the area of Life Sciences, was the first university publication of Ecuador to be included in SCOPUS, Elsevier publishing house and indexed in the Emerging Source Citation Index of the Web of Science (WOS). This edition presents articles by authors from 5 countries and 16 Universities and Research Centers. We started this number 31 with the topic of weather monitoring, in an effort between the Sciences Department of Environmental Systems of Switzerland and Universidad de Cuenca, led by Dr. Ryan Padrón and his excellent team. In addition, researchers from Universidad de las Fuerzas Armadas, led by Teófilos Toulkeridis, analyze the problem of perceptions in the important and current topic of Climate Change.

“…High ambient temperature and high relative humidity (RH) or low RH occurring during the hot-humid or dry season have been shown to cause heat stress in broilers [3,4]. The fast growing commercial broiler chickens are particularly susceptible to heat stress to induce metabolic disorder [5,6,7]. In addition, global warming will further accentuate heat stress related problems.…”

Background: Air temperature and humidity are two important climatic elements that affect animal welfare and health. The prevailing hot and humid or dry climate is one of the major constraints for optimum poultry production especially in the tropics and subtropical regions. Many studies have suggested that exposure hot-humid or dry climate is associated with a high risk of metabolic imbalance; however, the underlying metabolic route caused by low or high RH climate is not yet well understood. Therefore, we used a comprehensive UHPLC-Q-TOF/MS-based metabolic profiling of fecal samples to explore the effects of hot-humid and dry on metabolic pathway in broilers.Results: Significant changes in the levels of 36 metabolites were detected. Evidence of changes in gluconeogenesis associated to pyruvate metabolism, galactose metabolism and ABC transporter were observed. In addition, hot-humid and dry stress also affected protein translation process caused by aminoacyl-tRNA biosynthesis, which may be associated with protein synthesis and hormone secretion disorders. Furthermore, we observed significant changes in primary bile acid biosynthesis and taurine and hypotaurine metabolism, which indicated that fat synthesis was affected. We also observed significant changes in arginine and proline metabolism and histidine metabolism, which were associated with skin vasodilation and blood flow.Conclusions: These results provide biochemical insights into metabolism route of hot-humid or dry climate.
