廿年前的記憶
現在大概有很多新鮮的說法.......................
容易被黴菌感染的穀物是受損的穀物,不管是在種植地上或處理過程,不良的榖物都會破碎
黴菌感染後在適宜的環境下產生黴菌毒素
台灣有95%的玉米都是購自美國
美國國內市場或出口玉米都有一定的規格 (據我所知,老美這方面很有制度).不同規格的玉米,不同的價格.除非買方"趴怠".否則................
用合約與大宗物資商說清楚,你要用多少價格買什麼級的玉米(自己要瞭解玉米分級)或請榖物商教你
到台灣後,如何保護自己的豬呢?
去除污染最嚴重的部份----篩掉(這在現場做得到.下到斗升機前經過自製篩網.網目看自己要讓多少垃圾(碎粒及石粉)進入飼料中)
