During the winter six months, when the cows are on dry 

 feed, they should produce, on the average, 20 pounds of milk 

 per day. Most dairymen who practice this rotation feed all cows 

 in milk practically the same ration, so that for 183 days on 

 winter feed but one ration, which is given below, has been fig- 

 ured to cover the average production of 20 pounds of milk per 

 day for that period.
