Conteúdo: | Eight forages were fed in small quantities to cattle with oesophageal fistulae. The feeds and boluses were analysed for Ca, Mg, S, Mn, Mo, Cu, Zn, and Ti. Bolus composition could be used to predict dietary levels of Ca, S, Cu, and Mg with resonable precision (error <+- 9 per cent), but feed concentrations of Mo and Mn could be predicted only with an error of +- 15 per cent. Levels of Zn in boluses could not be used to predict dietary levels, since bolus Zn greatly exceeded athat of the feed. The presence of Zn in bovine saliva was demonstrated. Concentrations of Ti in feeds and boluses appears to provide a potentially useful method for the identification of those contamined with soil during grazing studies.
