Ten healthy lactating crossbred (Jersey × Non descript) cows were selected to study the different macro and micro mineral concentrations of milk. The overall mean calcium, inorganic phosphorus, magnesium, sodium, potassium, copper and iron concentrations were found to be significant (P<0.01), among different days of lactation i.e. 15 to 180 days of lactation. However, manganese and zinc did not differ signifiCantly among these periods.
