| Popis: | Individual milk samples from Holstein Friesian cows were collected and analysed by inductively coupled plasma optical emission spectrometry (ICP-OES) and titration for the determination of calcium (Ca), phosphorus (P) and titratable acidity (TA) contents, respectively. Prediction models were obtained using partial least squares (PLS) regression analyses using two statistical packages. The average Ca, P and TA were 1156 mg kg−1, 934 mg kg−1 and 3.42 °SH 50 mL−1, respectively. Pearson's correlations between Ca and P and other milk traits were significant (P |
