摘 要
赭曲霉毒素是一种常见的食物中毒物质，对动物的生长发育产生严重的不良影响。本研究旨在探究赭曲霉毒素对鸡生长发育的影响，并提出相应的防控措施。通过实验对不同浓度的赭曲霉毒素进行饲料添加，观察鸡的生长指标和生理指标，并进行组织学和生化学分析。结果表明，赭曲霉毒素显著降低了鸡的生长速度和体重增长，同时导致肝脏和肾脏的结构和功能异常。进一步分析发现，赭曲霉毒素引起了鸡体内氧化应激反应的激活，增加了氧自由基的产生，并降低了抗氧化酶活性。

Abstract
Ochratoxin is a common food poisoning substance, which has serious adverse effects on the growth and development of animals. The purpose of this study was to investigate the effects of ochratoxin on chicken growth and development, and put forward corresponding prevention and control measures. Different concentrations of ochratoxin were added to feed, the growth and physiological indexes of chickens were observed, and histological and biochemical analyses were carried out. The results showed that ochratoxin significantly reduced the growth rate and weight gain of chickens, while causing structural and functional abnormalities of liver and kidney. Further analysis showed that ochratoxin induced the activation of oxidative stress in chickens, increased the production of oxygen free radicals, and decreased the activity of antioxidant enzymes.
