饲料中玉米赤霉烯酮的危害和脱毒方法研究进展 总被引：1，自引：0，他引：1
玉米赤霉烯酮(Zearalenone,ZEN)是一种具有类雌激素活性的霉菌毒素,有较强毒性,给畜牧生产及人类健康造成极大威胁。本文对ZEN的生殖毒性、免疫毒性、肝肾毒性及其可能的作用机理,以及ZEN脱毒方法研究进展进行综述。 相似文献

在京黄肉鸡和京白蛋鸡上应用 Sibbald“鸡真代谢能”快速测定法,测定了脱毒菜籽饼,菜籽饼、豆饼和鱼粉的表观代谢能含量和氨基酸的消化率。试验结果表明:(1)酸法脱毒工艺生产的脱毒菜籽饼与原菜籽饼的表观代谢能含量相近,分别为8.91和9.41MJ/kg(蛋鸡);(2)在13种饲料氨基酸中,脱毒菜籽饼和菜籽饼低于鱼粉和豆饼,各占21.65%,20.41%;(3)脱毒菜籽饼在蛋鸡体内氨基酸的平均消化率为87.73%,比鱼粉或豆饼中氨基酸的平均消化率仅低4.25%或2.36%,但比原菜籽饼高15.32%,说明脱毒工艺提高了菜籽饼中氨基酸的消化率。试验证明,用脱毒菜籽饼代替鸡饲粮中的豆饼是可行的。同时,还测得肉鸡对饲料中能量的利用和氨基酸的消化率高于蛋鸡,用四种蛋白质饲料饲喂京黄肉鸡的 AME 值平均比京白蛋鸡高3.74%,氨基酸的消化率京黄肉鸡比京白蛋鸡高5.79%。 相似文献

采用饲料分析方法、银量法和紫外分光光度法测定高温高压、酸处理及土炕加热三种不同脱毒处理后菜籽饼（粕）中营养成份及异硫氰酸盐（ＩＴＣ）、口恶唑烷硫酮（ＯＺＴ）和硫代葡萄糖甙含量。结果：高温高压法营养成份损失少，酸处理无氮浸出物及灰分含量增加，高温高压法对ＩＴＣ的脱毒效果明显优于酸处理法（Ｐ＜０．０１），但对ＯＺＴ的效果不及酸处理法和土法（Ｐ＜０．０１）；三种方法对硫代葡萄糖甙的效果无明显差异（Ｐ＞０．０５）。 相似文献

The environment is currently polluted by thousands of chemicals or xenobiotics introduced into the environment by man to meet
the demands of the modern era. Every day we encounter this negative side of human civilization, but have done little to lessen
the rate of pollution. Although the entire biosphere is polluted it is water resources that are the most polluted because
water is the ultimate sink for many contaminants. Thus, fish are the most vulnerable of all animal species. They are helpless
because they cannot avoid the polluted habitat and face this contamination by default. Nevertheless, fish are found to survive
under extreme conditions when their natural habitat has been compromised to a great extent. However, fish are highly sensitive
to small environmental changes and their populations gradually dwindle if pollution continues unabated. However, we know that
there are instances when water is cleaned and the rate of repopulation by different fish species has gained momentum, restoring
the ecological balance. Thus, fish are considered reliable bioindicators of water pollution and fish ecotoxicology has received
much attention in recent years, and fish toxicology has been able to defend a significant position in the arena of xenobiotics
research over the years. This review deals with some of the major intoxication and detoxication signals manifested by fish
exposed to arsenic (As), which is presently one of the most worrying metalloids in water pollution. 相似文献

用明星肉仔鸡420只研究了脱毒菜籽饼-玉米型饲粮的应用问题。试验设置8种饲粮,高能和低能各4种,脱毒菜籽饼代替豆饼的比例为:0,20,50,75和100%。试验结果表明:(1)脱毒菜籽饼对肉用仔鸡无毒害作用,适口性好,在保持饲粮营养水平一致时,能以任何比例替代饲粮中的豆饼,(2)肉仔鸡饲粮中赖氨酸:精氨酸的比值对饲粮的利用率有较大的影响,脱毒菜籽饼-玉米型肉仔鸡饲粮尤应重视精氨酸的不足;(3)在低能无鱼粉饲粮中,脱毒菜籽饼与豆饼配伍,可以取得较好的效果。 相似文献

用平均体重1.2kg 的京黄商品代肉鸡,分5组饲喂1个月,各组鸡饲粮的营养水平保持一致,但脱毒菜籽饼配比不同,分别占5%,15%,25%,30%,0%。试验结果表明:各组鸡的累积增重和耗料量差异不显著(P>0.05),屠宰后鸡的肝脏和甲状腺的重量组间差异也不显著(P>0.05),说明脱毒菜籽饼对鸡无不良影响,能代替豆饼大量用于饲养肉鸡。经济效益分析表明,使用脱毒菜籽饼能使饲粮价格降低,若使用量达到30%,饲料价格可降低18.64%。 相似文献
