Basal diets were prepared that contained 75% hay since the ultimate aim of the experiment was to establish a bioassay for fluorine in forage crops.

| Summary: | Two six-week fluorine feeding trials were conducted with young growing guinea pigs as test animals. Basal diets were prepared that contained 75% hay since the ultimate aim of the experiment was to establish a bioassay for fluorine in forage crops. Sodium fluoride was added to the basal diets of some groups to achieve levels of fluorine ranging from 19 to 130 p.p.m. To other groups, fluorine-containing hay grown in the vicinity of a large industrial operation was fed, resulting in dictary fluorine levels of the hay-meal ration ranging from 60 to 112 p.p.m. Fluorine in the diet depressed the feed intake and weight gains of guinea pigs when its level in the complete diet approached 70 p.p.m. |
