Meg asks: << "Casein synthesis is low or absent in early lactation,
increases rapidly, and then decreases. Early milk whey:casein is 90:10, then
mature milk 60-40 then later lactation 50:50. Why is this different from the
generally stated 40:60 ratio. Is that an average?>>

The 60:40 ratio is only accurate at one point in time. And that is one of
the problems measuring milk composition - it varies so much even within a
single day, and even more over time.
