【摘要】 应用Hy-Line新生公雏研究了环境高温应激和超氧化处理对雏鸡肝脏中丙二醛含量,以及谷胱甘肽过氧化物酶活性的影响,同时观察了通过卵黄囊联合注射微量抗氧化微营养素对机体抗应激能力的影响。结果表明:1.高温(40℃)应激处理和在常温条件下注射氢过氧化枯烯(CHPO)均可对新生雏鸡肝脏发生相似的脂质过氧化作用。2.通过外源补充抗氧化微营养素Vit.E、Vit.C、Se、Cu、Zn,可以有效地抑制雏鸡肝脏发生氧化损伤。3.评价机体抗氧化机能时,适宜的采样时间应在注射CHPO 16h以后进行。更多还原

【Abstract】 The 0-day-old Hy-Line neonatal chicks were used to investigate the influences of heat-stress and per-oxidative treatment on the MDA content and GSH-px activity in the liver. The anti-peroxidative micronutrients were also investigated. The results showed that:1) Heat-stress with the ambient temperature of 40℃ caused similar per-oxidative effect to CHPO injection in the liver of neonatal chicks. 2) Hepatic oxidative damage was efficiently improved by supplying Vit.E, Vit.C, Se, Cu and Zn. 3) The optimum sampling time for the assessment of body anti-oxidation ability is 16 hours post-CHPO injection.更多还原
