Cobalt and molybdenum contents of pasture plants on dairy farms of the eastern region of Uganda
H. Ssekalo
Cobalt and molybdenum contents of fifteen pasture plants on the dairy farms of the eastern region of Uganda were determined. Five of the six major plants (Chloris gayana, Hyparrhenia rufa, Panicum maximum, stylosanthes gracilis and Paspalum commersonii) had mean annual dry matter cobalt contents falling within the range of 0·13-0·25 p.p.m. The seasonal variation for these five species indicates that they probably contain sufficient cobalt for cattle for most of the year. The mean annual dry matter molybdenum content of the six major species (range of about 0·60 to 1·10 p.p.m. Mo) and their seasonal variation indicate that copper availability was unlikely to be affected.
