Description
The trace mineral composition of the skeleton was studied in 42 Romney wether lambs, which were divided into 7 treatment groups· and grazed on a ryegrass-white clove. pasture. The trace element intakes were increased by drenching daily with various salt solutions. Treatments were (a) control distilled water (b) 8 mg Cu (c) 580 mg Fe (d) 350 mg Mn (e) 2 mg Mo (f) 0.08 mg Se and (g) 30 mg Zn. Treatments had no significant effect on the mean DM intakes (1.2 kg/day) or live-weight gains (178 g/day). Increasing the Mo, Se and Mn, intakes increased their concentrations in bone by over 50% while no: changes were observed for Cu, Fe and Zn. A comparison of the estimated skeletal and blood trace element pools showed that the skeleton is, for many trace elements, not an effective storage tissue to maintain blood trace element levels.
