The lifetime effects of level of naturally occurring soil fluorine and nutritional level upon physiological changes in and performance of beef cattle were studied. The effects measured were fluorine (F) uptake by bones of cows and calves, changes in teeth condition, reproductive performance of cows, and weight changes (rate of growth) of cows and calves. Seven groups of cattle were managed according to one of the following treatments: low fluorine soil-good nutrition (LFS-GN); low fluorine soil-low nutrition (LFS-LN); and high fluorine soil-good nutrition (HFS-GN); high fluorine soil-low nutrition (HFS-LN). Cows grazing pastures grown on LFS were 66 pounds heavier at maturity than those grazing HFS pastures. Growth curve parameters indicated that the effects of LN and HFS on mature weight were additive. Accumulation of F in bone appeared to be primarily dependent on the concentration of F in the ingested feed and the period of time over which such ingestion occurred. Fluorine accumulation was more rapid in young calves than in older animals. 21 references, 5 figures, 28 tables.
