where PT represents the number of days after calving atwhich the lactation peak is reached. In this case themaximum daily peak yield (PY) is estimated by insertionof the value obtained into equation [1]. The estimatedmilk yield in an arbitrary period (M) is expressed with adetermined integral [equation 3
