In view of the implication of ley‐farming in the increasing incidence of hypomagnesaemia, a preliminary study has been made of the blood serum calcium and magnesium levels in bullocks grazing leys consisting mainly of S24 ryegrass or S170 tall fescue, and old pastures. It was found that the serum magnesium was significantly higher while the animals were grazing the leys and that the tall fescue appeared to provide more magnesium than the ryegrass.
