麦秸秆用于实验动物垫料物理化学特性比较研究

目的 比较研究麦秸(气爆处理后) 、玉米芯、刨花及纸质四种垫料含水量、吸水性、保温性、重金属和有机农 药残留等物理化学特性以及微生物污染情况,为新型麦秸实验动物垫料开发应用提供科学依据。 方法 依照北京 地方标准,对麦秸垫料与其他三种垫料的含水量、吸水性、重金属及农药残留情况等进行测试与比较分析,通过升、 降温实验比较四种垫料的保温性。 结果 麦秸垫料含水量、吸水性、重金属及有机农药残留符合北京地方标准。 结论 麦秸垫料吸水性显著优于其他三种垫料,保温性能好,微生物含量少,具有来源广、价格低、易保存等优点, 并且可减少林木资源消耗,利于环境保护,可作为产业化推广应用。

Comparative Study on the Key Points of Quality Control of Wheat Straw Used as Rodents Bedding

Objective Compare and study the physical characteristics and sanitary indexes of the moisture content, hygroscopicity, heat preservation and hygienic of wheat straw ( after air explosion treatment) , corncob, shaving and paper, so as to provide scientific basis for the development and application of new type of wheat straw in laboratory animal bedding materials. Method According to the local standards of Beijing, the moisture content, water absorption and hygienic indexes of wheat straw bedding materials and other three bedding materials were tested. Result The moisture content and water absorption of wheat straw, the heavy metal residue of wheat straw and the wheat straw pad meet the standard. Conclusion Wheat straw bedding material has good water absorption and heat preservation performance, has the advantages of wide source, low price, easy preservation, and can reduce the consumption of forest resources, is conducive to environmental protection, and can be used as industrial promotion and development.
