Mink (Mustela vison) kits still nursing, and adult male mink were fed diets containing various levels of fluorine (as NaF) to determine the effects on health, growth and pelt quality. Different groups were fed diets containing 25.5 (control), 46.0, 111.5 or 287.0 ppm fluorine (on a wet basis) for 7-8 mo. Gross, radiographic and microscopic changes were seen in bones from some animals ingesting the higher levels of fluorine. Chemical analyses for fluorine generally reflected levels ingested. Fluorine caused no detectable differences in pelt quality. After data were evaluated, tolerance levels in the feed of not more than 50 ppm fluorine for breeding stock and 100 ppm fluorine for animals being raised only for pelts are recommended.
对仍在哺乳的水貂幼崽（鼬属水貂）以及成年雄性水貂投喂含有不同氟含量（以氟化钠形式）的日粮，以确定其对健康、生长和皮毛质量的影响。不同组水貂被投喂含25.5（对照）、46.0、111.5或287.0 ppm氟（湿基）的日粮，持续7 - 8个月。在摄入较高氟含量的一些动物的骨骼中观察到大体、放射影像学和微观变化。氟的化学分析结果通常反映了摄入水平。氟对皮毛质量未造成可检测到的差异。在对数据进行评估后，建议种畜饲料中的氟耐受水平不超过50 ppm，仅用于取皮的动物饲料中的氟耐受水平不超过100 ppm。
