Phosphorus excretion in faeces was measured by total collection using dairy cows fed five amounts of P in a 5 × 5 Latin square design with three week periods. Milk production was 23 ± 4 kg per day at the onset of the trial (DIM 185 ± 11). Different quantities of monosodium phosphate (MSP) were added to a basal diet to obtain daily P intake levels of 44, 67, 92, 117 and 142 g (2.4, 3.7, 5.1, 6.4 and 7.8 g P kg¿ 1of DM, respectively). Faecal P excretion increased linearly (r2 = 0.97) as dietary P intake increased and the apparent digestibility of P was calculated to be 0.37, 0.28, 0.22, 0.21 and 0.22, respectively. The relatively low apparent digestibility is explained by excess P intake in relation to the requirements. The concentration of P...
