Data from 3 grazing experiments were used in calculations of animal P balance and models were constructed of gut P balance and body P balance. From the gut P balance model, endogenous loss of P ranged from 8 to 29 mg P per kg liveweight per day. P supplement requirements predicted from the relations developed were similar to those currently recommended for growing cattle, but when extended to pregnant and lactating cows, P supplement requirements were higher than currently recommended commercially.
