Milk may be tainted occasionally when cows are pasturing on sweet
clover. However, the large majority of farmers who pasture sweet
clover on an extensive scale report very little or no trouble. The
flavor imparted to milk at times is not disliked by all people, as
some state that it is agreeable and does not harm the market value of
dairy products in the least. This trouble is experienced for the most
part in the early spring. The tainting of milk may be avoided by taking
the cows off the pasture two hours before milking and keeping them off
until after milking the following morning.
