PLS-DA score plots for overall comparison of fatty acid (panel A) and non-volatile polar metabolite (panel B) profiles of colostrum (day 0; red), transient milk (day 3; blue) and mature milk (day 17; green) samples collected from sows in different parity numbers. The blocks in (
), (
) and (
) shape correspond to the samples collected from sows in parity 1, parity 2–6 and parity 7, respectively.
