Extract

The Agricultural Research Council (1980) has recently published revised estimates of the phosphorus requirements for ruminants. These new estimates are considerably lower than those formerly recommended (Agricultural Research Council, 1965) and some concern has been expressed as to whether or not they are adequate (Cooke, 1982; Todd, 1983).
