摘要

我们之前的研究表明,在长期暴露于高温环境5天的肉鸡中,观察到ros诱导的骨骼肌氧化损伤减轻,生产效率提高。在这项研究中,我们研究了这种减少的水是否也可以改善暴露于14天慢性热暴露的肉鸡的这些参数。孵化后14 d分别饲喂带水对照饲粮和电解还原水对照饲粮,然后分别进行热应激(34℃)和热中性温度(24℃)处理。研究了骨骼肌底物代谢(3HADH和CS活性)、腺嘌呤核苷酸浓度、酶清除系统。我们证实,与对照肉鸡相比,热应激肉鸡的增重和饲料消耗降低。相比之下,与热应激对照肉鸡相比,热暴露肉鸡的生产性能明显提高。在长期热处理条件下,还原水处理肉鸡的CS活性较高,表明还原水可以通过调节TCA循环来提高肉鸡的产能能力。我们还发现,在这种条件下,还原水可以明显提高总腺嘌呤核苷酸(TAN)、腺苷化能量电荷(AEC)和ATP / ADP比率。另一方面,给予还原水的肉鸡体内SOD、过氧化氢酶和GPx活性保持相对稳定,表明还原水可以支持酶清除系统。综上所述,饲粮中添加电解还原水可通过调节tca循环酶提高肉鸡能量产生能力,从而提高生产性能。

Electrolyzed reduced water could regulate muscular energy producing ability of heat-exposed broiler chickens
We have previously shown that alleviation in ROS-induced oxidative damage to skeletal muscle and improvement in production efficiencies are observed in broiler chickens supplied with electrolyzed-reduced water when exposed to 5 days-long chronic heat exposure. In this study, we investigated whether this reduced water may also improve those parameters in broiler chickens exposed to 14 days-long chronic heat exposure. Broiler chickens (Gallus gallus) were fed either a control diet with tape water or control diet supplied with electrolyzed-reduced water for 14 d after hatch, and then exposed either to heat stress (34oC for 14 days), or kept at a thermoneutral temperature (24oC). Skeletal muscle substrate metabolism (3HADH and CS activities), adenine nucleotides concentration, enzymatic scavenging systems were studied. We confirmed that heat-stressed broilers decreased weight gain and feed consumption compared to control broilers. In contrast, heat-exposed broilers supplied with electrolyzed-reduced water significantly and definitely improved performance when compared to heat-stressed control broilers. On exposure to long-term heat treatments, broiler supplied with reduced water showed higher CS activity, indicating that the reduced water could improve energy-producing ability via modulating TCA cycle. We also found that the reduced water could definitely improve the total adenine nucleotide (TAN), adenylated energy charge (AEC), and ATP to ADP ratios under such conditions. On the other hand, broiler chickens supplied with reduced water kept relatively constant the SOD, catalase, and GPx activities, implying that reduced water could support the enzymatic scavenging systems. Taken together, these results suggest that broiler chickens supplied with electrolyzed-reduced water could improve energy producing ability via modulating TCA-cycle enzyme, and lead to improving performance.
