Determination method of Feed montmorillonite Ammonium exchange capacity Theory：　 Heat sample with NH4CL solution, make NH4+ adsorbed completely by montmorillonite, because ions K+ and NH4+ are easy to be changed by montmorillonite, so wash sample by KCL solution, NH4+ is exchanged, NH4+(ka<···

Mycotoxin pollution has become a major hazard affecting the development of agriculture, feed industry and aquaculture in the world. How to understand and control mycotoxin has become the primary issue to solve feed safety and livestock product safety, and its importance and urgency should cause us t···

Abstract: Evaluate adsorption effect for the Aflatoxin B1 with 5 different content montmorillonite as different adding amount in ELISA method in vitro experiment, discover that montmorillonite content are positive correlation to adsorption rate a certain degree, beyond this range, alt···

Introduction: The specific surface area of montmorillonite is 40 times that of conventional powder. Since montmorillonite has such a strong adsorption capacity, will it also absorb nutrients in the intestinal tract, such as vitamins, and have side effects? However, in a study of the effects of montm···

According to <Investigation and analysis of the dairy feed mycotoxin the infection situation> (Ma Meirong) reported: A random sample of 3 different scale dairy feed 32 raw materials and ingredients, use imported ELISA kit for detection of aflatoxins, zearalenone, ochratoxin and vomitoxin etc 4···
