摘要
为了查明鸡蛋品质异常的原因,保证鸡蛋品质。通过对新疆南部某养殖场发生的“橡皮蛋”事件进行调查,清楚了事件发生的原因,并提出了相应的处理措施。经饲料成分调查发现,饲料中棉籽饼的含量为16%,初步判断为棉酚中毒。饲料中VA、钙、铁及蛋白质缺乏,鸡生病或受到应激,鸡蛋贮藏温度低于10℃和贮藏时间延长均会增高“橡皮蛋”的发生率。通过减少饲料中棉籽饼的含量至5%,在饮水中加入多种维生素等措施消除了“橡皮蛋”现象。“橡皮蛋”的发生原因是棉酚中毒。在鸡日粮使用棉粕（棉饼）应先进行脱毒处理,而脱毒棉粕（棉饼）用量应控制在5%~8%,饲料棉酚含量应控制在50 mg/kg以下。
The aim of the research was to investigate the cause of abnormal egg quality so as to ensure the egg quality. Based of the investigation of the ＂rubber eggs＂ event that appeared in a farm in the south of Xinjiang, the cause of the event was found out and the corresponding measures were put forward .Through the investigation of the feed ingredients, it was found that the cotton seed cake content in feed was 16%, so the event cause was preliminarily judged as gossypol poisoning. The incidence of ＂rubber egg＂ was increased in some circumstances such as deficiency of VA, Ca, Fe and protein in feed, chicken being in disease and under tension, the egg storage temperature below 10℃ and the extension of the storage time. The incidence of ＂rubber eggs＂ was eliminated through some measures such as reducing the cotton seed cake content in animal feeds to 5 % and supplementing muhffold vitamins in drinking water, The cause of ＂rubber egg＂ incidence was confirmed as gessypol poisoning. The Cottonseed meal/eake should be detoxieated firstly when those were used in chicken diets. The amount of detoxleated cotton seed meal/eake should be controlled at 5% - 8% and the gossypol content in feed should be controlled below 50 mg/kg.
