The inhibition of fungal activity in poultry feed and ingredients by gentian violet was investigated by measuring respiratory CO2 liberated into the headspace gas above samples of feed and ingredients. Inhibition by gentian violet depended on 1) the lot of corn meal, 2) the concentration of gentian violet, 3) the moisture of the substrate, 4) time of incubation, 5) particle sizes of corn meal and gentian violet, and 6) temperature of a short heating episode mimicking the feed-pelleting process. These same factors were reported earlier to control and limit the activity of organic acid mold inhibitors. These results imply that differences between gentian violet and other mold inhibitors used in poultry feed are quantitative rather than qualitative.
通过测量释放到饲料和成分样品上方顶空气体中的呼吸二氧化碳，研究了龙胆紫对家禽饲料和成分中真菌活性的抑制作用。龙胆紫的抑制作用取决于：1）玉米粉批次；2）龙胆紫浓度；3）底物湿度；4）孵育时间；5）玉米粉和龙胆紫的颗粒大小；6）模拟饲料制粒过程的短时间加热温度。早些时候报道这些相同因素可控制和限制有机酸霉菌抑制剂的活性。这些结果表明，家禽饲料中使用的龙胆紫与其他霉菌抑制剂之间的差异是定量的而非定性的。
