Effects of melittin on production performance, antioxidant function, immune function, heat shock protein, intestinal morphology, and cecal microbiota in heat-stressed quails

Folic Acid and Taurine Alleviate the Impairment of Redox Status, Immunity, Rumen Microbial Composition and Fermentation of Lambs under Heat Stress

“…Generally, the antioxidant enzyme system is considered to be the first barrier of antioxidative defense in animals, which is mainly composed of SOD, GPx, and catalase [9]. HS can repress the activity of mitochondria to increase the production of reactive oxygen species (ROS)/free radicals, which disrupts the dynamic balance of redox and induces oxidative stress [12,35].…”

“…Sheep, as a case of ruminants, have intensive metabolic heat production due to feed fermentation in the rumen and a relatively small surface: volume ratio, and are particularly susceptible to HS due to a limited capacity for heat dissipation [5,6]. As one of the major environmental stressors, HS not only induces a range of negative effects comprising deprived appetite, decreased feed intake, and reduced weight gain, but is deleterious to reproduction performance, immune response, antioxidative activity, gastrointestinal microbiota and relevant function [4,[7][8][9]. Hence, HS is often defined as a sensation of discomfort that evokes aberrant physiological reactions, i.e., increased body temperature, accelerated respiratory rate, and elevated heart rate [8].…”

“…Although the regulation of ambient temperature and relative humidity to mitigate HS is the most directly effective approach, the high cost of the control system greatly restricts its application to farm animals [10]. However, the modification of the diet with functional additives, such as the supplement of functional additives (including minerals), vitamins, active ingredients of Chinese traditional herbs, amino acids, probiotics, etc., has become an economically feasible mitigation technology to reduce the negative consequences induced by HS [9,11,12]. Folic acid, a B vitamin, is vital to embryonic formation and fetal development because it plays crucial roles in the repair and methylation of DNA, gene expression and modification, and amino acid metabolism [13].…”

Impacto del transporte de la codorniz japonesa a cuatro edades desde la costa a la sierra peruana en el inicio de la puesta y el rendimiento productivo

“…La suplementación dietética de la Coenzima Q10 tiene efectos beneficiosos sobre algunas características reproductivas de codornices hembra bajo estrés oxidativo (Rafieian-Naeini et al, 2021). La melitina en la dieta mejora los efectos adversos del estrés sobre la función antioxidante, la función inmune, y el rendimiento productivo (Qin et al, 2023). Asimismo, se sugiere controlar la velocidad del aire y temperatura en las jaulas para eliminar el calor de la superficie de las codornices a fin de evitar efectos negativos sobre el desempeño productivo de la ponedora (Santos et al, 2019).…”

Biogenic Selenium Nanoparticles Synthesized with Alginate Oligosaccharides Alleviate Heat Stress-Induced Oxidative Damage to Organs in Broilers through Activating Nrf2-Mediated Anti-Oxidation and Anti-Ferroptosis Pathways

“…It is already clear that HS results in reduced feed intake, growth restriction, and metabolic disorders in broilers [2,3]. Meanwhile, multiple studies have found that HS-induced oxidative stress in organs, leading to organ injury and dysfunction, which is also an important reason for HS causing production losses in broilers [4][5][6]. The spleen and bursa of Fabricius are essential immune organs for broilers [7].…”
