Description
The mineral contents (Ca, P, Mg, K, Na, Fe, Cu, Zn, and Mn) of white clover grass without nitrogen and grass-only pastures with annual nitrogen rates of 0, 120 and 250 kg ha-1 were studied in 1994 and 1995. The pastures were grazed twice per season by growing lambs. The white clover contents averaged 25% and 42%, respectively. The Ca and Mg contents and the Ca/P ratio were higher, and the K/(Ca+Mg) equivalent ratio lower in white clover grass than in grass-only swards. The P content of white clover grass was similar to that of grass, and the K content increased with increasing N fertilization. The Cu content did not differ between pastures, and it was higher than recommended (5.1 mg kg-1 DM) in all pastures. Nevertheless, no health problems (copper toxicosis, grass tetany) were observed in grazing lambs.

Mineral Contents of White Clover Grass and Nitrogen Fertilized Grass Pastures for Lambs
