试验以M38-A液体微量稀释法测定两种自制复合酸化剂（OAI和OAII）对8种常见污染饲料霉菌的最低抑菌浓度（MIC），以及饲料pH、系酸力的影响。结果显示：两种固体复合酸化剂对8种霉菌的MIC范围为1.25～5.00 mg/mL，酸化剂OAI和OAII的MIC 几何均值分别为1.93、2.73。饲料中添加0.1%、0.2%的复合酸化剂时，OAI和OAII均能显著降低饲料的pH和系酸力（P＜0.01）。由此可见，两种酸化剂均能有效防止饲料被常见霉菌污染，且能酸化饲料。
試驗以M38-A液體微量稀釋法測定兩種自製複閤痠化劑（OAI和OAII）對8種常見汙染飼料黴菌的最低抑菌濃度（MIC），以及飼料pH、繫痠力的影響。結果顯示：兩種固體複閤痠化劑對8種黴菌的MIC範圍為1.25～5.00 mg/mL，痠化劑OAI和OAII的MIC 幾何均值分彆為1.93、2.73。飼料中添加0.1%、0.2%的複閤痠化劑時，OAI和OAII均能顯著降低飼料的pH和繫痠力（P＜0.01）。由此可見，兩種痠化劑均能有效防止飼料被常見黴菌汙染，且能痠化飼料。

Minimum inhibitory concenttation (MIC) of two self-made compound acidifiers (OAI,OAII) against eight strains of mould that contaminating feed was determined by M38-A microdilution method.Effects of acidifier on pH and buffer capacity of feed were also measured.The results showed that:MIC of two acidifiers against eight mould were 1.25 ~5.00 mg/mL.The minimum geometric mean of the MIC of acidifier OAI and OAII were 1.93 and 2.73,respectively.At the same time,both OAI and OAII could significantly decrease pH and buffer capacity of feed at addition of 0.1%and 0.2%(P<0.01).In conclusion,two acidifiers could prevent contamination of feed by mould and acidify feed.
