IRON CONCENTRATIONS IN SOIL, PASTURE AND BLOOD PLASMA OF BEEF CATTLE REARED IN SUCKLING COWS SYSTEM

Abstract

The objective of this study was to compare concentrations of iron (Fe) in soil, pasture sward and blood plasma of extensive reared Aberdeen Angus bulls and heifers on a farm in the foothills of the Orlické Mountains. We sampled soil, pasture sward from pasture areas and blood from 22 bulls and 22 heifers in the period from birth to weaning at regular intervals (81, 151, 189 and 273 days of age). Concentrations of iron were analysed. Not significant relationships were noted between soil and pasture iron concentrations (r = 0.32), pasture and blood plasma iron concentration (r = 0.39). In this study, there were not found relationships between iron-soil, forage and blood concentration in beef cattle reared in suckling cows The objective of this study was to compare concentrations of iron (Fe) in soil, pasture sward and blood plasma of extensive reared Aberdeen Angus bulls and heifers on a farm in the foothills of the Orlické Mountains.
