They likewise travel about much less, which also is economy. These facts enable the cow to yield milk upon less feed in winter than in summer. This becomes the more important when consider- able quantities of feed are purchased or where forage crops are raised on high-priced land. Nature forces the cow to yield milk for at least a few months after calving for the sustenance of its own calf. Thus the cow when comfortably housed, liberally fed and kindly treated may be expected to milk during the entire winter months. After a period of four to seven months most cows begin to slack off in.
