“…These results are in agreement with the previous findings of Hauck et al (1933), Phillips et al (1935a), and Gardiner et al (1968) showing decreased feed consumption in chickens fed high F. Simon and Suttie (1968) also found that dietary F depressed feed consumption in rats when the plasma F increased to 3 ppm, but that after a period of reduced food intake, feed consumption returned to normal. In the present experiment Strain x t i G t^^H xi x *~*s with laying hens, the same pattern for feed consumption was observed and adaptation to high F in the plasma was indicated by the fact that fluorotic hens overcame the depression in feed consumption after 6 weeks.…”

One hundred fifty Single Comb White Leghorn hens of two strains previously selected for either high eggshell strength (HES strain) or low eggshell strength (LES strain) were treated for 8 weeks with sodium fluoride added to a practical-type corn-soybean meal basal diet at 0, 300, 600, 900, or 1200 ppm. The HES strain was found to be more sensitive to fluorosis than the LES strain. High levels of dietary fluoride produced greater decreases in feed consumption, egg production, eggshell breaking strength, eggshell weight, and eggshell thickness in the HES strain than in the LES strain, despite the fact that the absolute intake of fluoride was greatest in the LES strain. Fluoride treatment significantly increased bone magnesium content in both strains and plasma phosphorus in the HES strain but did not significantly affect bone breaking strength or the concentrations of total calcium, ionized calcium, or magnesium in plasma of either strain. High fluoride treatment (1200 ppm) reduced the growth of HES progeny after 8 weeks of treatment of the hens, but LES progeny were not affected. These results suggest that the decreased sensitivity of the LES strain to fluoride may relate to its relatively greater (ca. 14%) volume of bone in which most absorbed fluoride is deposited.

“…Stuber and Lang (6) observed a number of hemophilic patients with high amounts of F in the blood, and they are inclined to accept the idea that a high F content of blood accompanies a long clotting period. Schwyzer (7), however, observed a very high degree of coagulability of the blood of rabbits, dogs, and pigeons which received F. Hauck, Steenbock, Lowe, and Halpin (8) have reported a few analyses of the calcium and phosphorus content of the blood of chickens receiving fluorides, but they admit that their data are insufficient to draw any definite conclusions. Phillips 9 All of the experiments were performed on dogs.…”

“…However, the other colloidal phosphate (#2b) resulted in good feed efficiency. Hauck et al (1933) found that 0.15 percent sodium fluoride (approximately 0.07 percent fluorine) had no effect but 0.3 percent sodium fluoride depressed the appetite and growth of young chicks. Further there was no relationship between the fluorine content of these colloidal phosphates and the growth response obtained.…”
