 season is often the critical time of the year for the dairy cow. 

 Probably as much loss occurs one year with another by lack of 

 feed at this time as occurs from improper feeding during the 

 winter. 



It is possible to hold up the milk flow by heavy grain feed- 

 ing but this is expensive. Provision should always be made to 

 have green crops on hand that may be cut and fed when needed 

 or to have silage available.
