Abstract
STUDIES of variations in the composition of cows' milk1,2 have revealed a progressive decline in the non-fatty solids content during the winter months, followed by a substantial and immediate rise When the cows are turned out to grass in the spring. Also it is widely recognized that on ‘going out to grass' cows often show an increase in milk yield, greater than the amount ascribable to the extra nutrients ingested.
