Abstract

The aims of this study were to determine the impact of storage practice and mold types on mold growth and aflatoxin B₁ (AFB₁) concentration in corn residue from local seed corn plants, the main roughage source of dairy farms in the northern region in Thailand. A total of 223 samples from 2 types of corn residue - dried and wet - were collected. Mold contamination was determined by spread plate technique, and aflatoxin B₁ (AFB₁) quantification was performed by a commercial enzyme-linked immunosorbent assay. Multivariate linear models were created to determine factors associated with fungal quantity and AFB₁ concentration. Results showed that the presence of Cladosporium spp. in the samples was associated with a lower risk of AFB1 contamination (P<0.05). In addition, appropriate storage practices, e.g. keeping feeds under a roof and using floor canvas under feed piles, gave lower risk of mold contamination and decreasing AFB₁ contamination.

储存条件和霉菌类型对泰国小农奶牛场饲料用玉米渣中黄曲霉毒素B1浓度的影响

本研究的目的是确定储存方式和霉菌类型对泰国北部地区奶牛场主要粗饲料来源——当地玉米种子植物的玉米残渣中霉菌生长和黄曲霉毒素B1 (AFB1)浓度的影响。共采集干、湿两种玉米渣223份样品。采用平板扩散法检测霉菌污染，采用商用酶联免疫吸附法测定黄曲霉毒素B1 (AFB1)含量。建立多元线性模型来确定真菌数量和AFB1浓度的相关因素。结果表明，样品中枝孢杆菌的存在与AFB1污染(P1污染)的风险较低有关。
