shed near the calf barn during the winter months. The feed is 

 entirely roughage, consisting of mixed hay and corn silage, with the 

 addition of corn stover from January to April. About the middle 

 of May they are again turned on pasture and receive no other feed 

 during the summer. This makes a total of 171 days, or nearly one- 

 half the second year, that the heifers are dependent upon pasture 

 alone. 



Table V gives the ration and the average quantity fed daily per 

 head for the different months. Each calf consumed during the 

 winter months an average of 1,120 pounds of hay, 3,250 pounds of 

 silage, and GT2 pounds of corn stover. 



The change in numbers from the second year is due to the addi- 

 tion of two heifer's in December, the transfer of a few head to the 

 dairy herd to fill vacant stalls, and the butchering in March of one 

 that proved to be undesirable.

COST OF FEED FOR THE SECOND YEAR. 



In the second year the feed cost as compared with the first year 

 is materially reduced, as shown in Table VI. This is caused by a 

 number of factors. First, both milk and concentrates, each of which 

 is a large item in the first year's feed cost, are omitted. Second, the 

 pasture period is longer. Pasture is the cheapest of feeds, and the 

 longer the stock can be kept on it the smaller will be the total yearly 

 feed cost. On the other hand, during the second year the quantity 

 of roughage fed is increased. However, roughage is a cheap feed, 

 and its increased cost in the second year does not offset the decrease 

 caused by the omission of milk and grain. 



The prices for the different feeds remain the same for the whole 

 period; hence, the cost each month varies with the quantity fed. The 

 costs for the year are as follows: Hay, $4.G0; silage, $6.50; corn
