Fifty-seven acres of the corn ground is sown to rye as soon 

 as the corn is cut, and the cows are on rye pasture two weeks in 

 the fall and forty days in the spring. The ground will be too 

 wet a portion of the time during the rainy weather to turn the 

 cows to pasture, and only 33 days of rye pasture are counted 

 during the year. While on rye the cows are given only one-third 

 of a ration of silage and hay with no grain. Ration No. 4 

 would therefore be fed only five months, and a ration composed 

 of 15 pounds of silage and 4 pounds of alfalfa hay is fed the 

 remaining 33 days while on rye pasture.

This shows that it takes .yy of an acre to support a cow 

 during the winter six months, with the catch crop of rye used 

 for pasture.
