Fig. 2. Production of energy corrected milk (ECM) in cows fed low phosphorus (P) (LP, ), medium P (MP, ▲) or high P (HP, □) including the treatment shift
from LP to former LP (FLP, ●). Early lactation (week 2 to 12) and late lactation (week 24 to 36) are indicated by arrows. Parturition at week 0 is indicated by
vertical arrow. Each data point is the least squares means (LSM)7 standard error of means (SEM). Note that the scale on y-axis starts at 15 kg/d.
