The influence of 1-mo ingestion of a ration containing 50, 100, 150, or 200 ppm fluoride (as sodium fluoride) on milk production and ration intake of Holstein cows was studied. The total amount of fluoride administered was mixed into the grain mix and fed twice each day. The concentrations of fluoride in plasma and urine were related to the concentration of fluoride in the ration. There was no effect of fluoride on hay intake, but there was a decrease in intake of the grain mix at an intake of 200 ppm fluoride. The ingestion of 150 or 200 ppm fluoride for 1 mo had a slight adverse effect on milk production. From these results we suggest that rations containing less than 150 ppm fluoride will not influence ration intake or milk production adversely if they are fed for a short time to mature cattle not suffering from other long-term adverse effects of fluoride ingestion.
研究了给荷斯坦奶牛投喂含50、100、150或200 ppm氟（以氟化钠形式）的日粮1个月对产奶量和日粮摄入量的影响。所投喂的氟总量混入谷物混合料中，每天分两次投喂。血浆和尿液中的氟浓度与日粮中的氟浓度相关。氟对干草摄入量没有影响，但在氟摄入量为200 ppm时，谷物混合料的摄入量有所下降。摄入150或200 ppm氟1个月对产奶量有轻微不利影响。从这些结果我们建议，如果短时间给未遭受氟摄入其他长期不利影响的成年奶牛投喂含氟量低于150 ppm的日粮，不会对日粮摄入量或产奶量产生不利影响。
