纳米蒙脱石在乳仔猪养殖中的应用 总被引：3，自引：0，他引：3
蒙脱石在乳仔猪的养殖中的应用越来越广泛，如治疗乳仔猪腹泻、代替氧化锌抗腹泻、仔猪护理、饲料脱霉和脱重金属。纳米蒙脱石对乳仔猪的腹泻有明显的治疗和控制作用，尤其对乳仔猪的红痢、黄痢、白痢等效果突出，可以完全替代氧化锌等高锌高铜添加剂，彻底解决饲料高锌高铜问题；纳米蒙脱石还可以用于仔猪护理，对皮肤、消化道及呼吸系统等无毒、无害、无刺激性，如涂抹在脐带还可使脐带迅速干燥，在去势、断尾后直接涂于伤口，可有效地消毒、止血；纳米蒙脱石添加到饲料中可对饲料中黄曲霉毒素B1等有害霉菌有明显的吸附脱出作用。 相似文献

纳米蒙脱石在养猪生产中的应用 总被引：2，自引：0，他引：2
纳米蒙脱石是采用优质天然蒙脱石为原料,经提纯、超微粉碎(纳米杂化)而得到的禽畜类绿色保健产品,源于天然,所以自然,可完全替代氧化锌和抗生素,控制猪仔腹泻特别是乳仔猪营养性腹泻更有效,彻底解决抗生素的耐药性和残留问题,成功化解氧化锌的高成本和副作用,同时对饲料具有防霉脱毒和改善铅诱导损伤的可能。纳米蒙脱石连同吸附的致病因子及重金属,随粪便一起排出,完全不进入血液,非常安全,无休药期,无毒副作用,不产生抗药性。1纳米蒙脱石可治疗仔猪和中大猪腹泻纳米蒙脱石是一种新型矿物药剂,用于治疗禽畜类腹泻、痢疾等,无药物残留、无耐… 相似文献

纳米蒙脱石替代氧化锌对断奶仔猪生产性能的影响 总被引：7，自引：1，他引：7
选取84头体重相近的二元杂交断奶仔猪,随机分为3个处理组,每个处理组4个重复,每个重复7头(公母比例为4:3),各个重复统计检验差异不显著.处理1(对照组)饲喂基础日粮,处理2(氧化锌组)和处理3(纳米蒙脱石组)分别在基础日粮中添加3 000mg/kg氧化锌和3 000mg/kg纳米蒙脱石,试验期为28d.结果表明,纳米蒙脱石在控制仔猪腹泻方面与氧化锌具有相同的效果;氧化锌组和纳米蒙脱石组的ADFI分别比对照组提高13.8%(P＜0.05)和12.4%(P＜0.05);纳米蒙脱石组与氧化锌组相比,试验前期料重比降低9.0%(P＜0.05),试验全期降低6.2%(P＜0.05).以上结果说明,在断奶仔猪日粮中添加纳米蒙脱石完全可以替代氧化锌控制腹泻,同时还可以提高饲料转化效率. 相似文献

纳米蒙脱石的吸附作用与治疗仔猪腹泻 总被引：1，自引：0，他引：1
蒙脱石也叫八面体蒙脱石或十六角蒙脱石,是一种良好的胃黏膜防护剂。蒙脱石对细菌有吸附作用,吸附力强弱与其带电性有关。蒙脱石对大肠杆菌、霍乱弧菌、空肠弯曲菌、金葡菌和轮状病毒及胆盐都有较好的吸附作用,且对表面带有粒编码蛋白（CS31A）的致病性带电病原菌有固定清除作用。研究表明,纳米蒙脱石比普通蒙脱石吸附能力高,对非感染仔猪腹泻总有效率高达94．1％,且价格低廉,毒副作用小。透射电镜分析表明,纳米蒙脱石吸附原毒素前后蒙脱石的粒径没有明显改变,XRD分析证实吸附原毒素后蒙脱石层间距没有发生变化。 相似文献

Eighteen (Duroc × Landrace × Yorkshire) castrated boars,55 days of age and weighing approximately 19 kg,were used to investigate the effects of montmorillonite nanocomposite on tissue levels of lead as well as changes in blood biochemical parameters in pigs fed lead contaminated diets.The barrows were randomly assigned to one of three treatments (n=6) including a control which were fed a basal diet based on corn and soybean meal.The remaining two groups were fed the basal diet supplemented with 10 mg/kg lead either with or without 0.5% montmorillonite nanocomposite for 50 days.Pigs treated with lead had significantly increased levels of lead in their tissues.Lead accumulated in all tissues of the body with the highest accumulation found in the hair.When montmorillonite nanocomposite was given along with lead,tissue concentrations of lead did not differ from the control.Fecal excretion of lead increased significantly in lead-exposed pigs treated with montmorillonite nanocomposite.A progressive and appreciable accumulation of lead was seen in blood with a concomitant increase in zinc protoporphyrin levels during the course of treatment.However,zinc protoporphyrin levels did not differ from the control when montmorillonite nanocomposite was administered along with lead.The activity of δ-amino levulinic acid dehydratase in blood was significantly increased in lead treated pigs compared with the control.However,in pigs treated with lead and montmorillonite nanocomposite in combination,the activity of δ-amino levulinic acid dehydratase was similar to control pigs.Our results indicate that montmorillonite nanocomposite treatment of pigs exposed to lead resulted in reduced lead concentrations in body tissues.It appears that montmorillonite nanocomposite functions by increasing fecal excretion of lead. 相似文献

本试验旨在研究蒙脱石对采食天然黄曲霉素毒素B1(AFB1)污染花生粕型饲粮的肉仔鸡生长性能和免疫机能的影响,确定蒙脱石作为霉菌吸附剂的饲用效果。选用288只1日龄爱拔益加(AA)健康公雏,随机分为4组,每组6个重复,每个重复12只鸡。正对照组饲喂玉米-豆粕型基础饲粮,负对照组饲粮用自然霉变花生粕(含AFB11 284.21μg/kg;前期、后期饲粮分别添加8.8%和12.0%)替代部分豆粕,试验组分别在负对照组饲粮中添加2.0 g/kg的天然或改性蒙脱石。试验期42 d。结果表明:1)与正对照组相比,霉变花生粕显著降低了肉仔鸡平均日增重(ADG)、平均日采食量(ADFI)、42日龄胸肌率和腿肌率以及血浆蛋白含量(P0.05),显著提高了料重比和免疫器官指数(P0.05)。2)与负对照组相比,天然或改性蒙脱石均显著提高了肉仔鸡ADG、ADFI及血浆蛋白含量(P0.05),显著降低了免疫器官指数(P0.05)。3)与天然蒙脱石组相比,改性蒙脱石显著提高了肉仔鸡ADG及血浆总蛋白和白蛋白含量(P0.05),显著降低了胸腺指数(P0.05)。综上,AFB1污染的霉变花生粕能降低肉仔鸡的生长性能和免疫功能,蒙脱石能缓解AFB1引起的不良影响,改性蒙脱石作用效果更佳。 相似文献
