REQUIREMENTS FOR KEEPING A COW ONE YEAR. 



The requirements for keeping a cow for one year are shown in 

 Table 3. It will be noted that there was a wide variation between the 

 quantities of purchased and home-grown concentrates fed. Most of 

 the dry roughage fed consisted of salable hay. Of course, the differ- 

 ence between the quantities of feed used in winter and in summer was 

 due to the large amount of pasture grazed during the summer. 



Table 3. — Number of cows, average production, and requirements for keeping a 

 cow, except charge for management, based on 'the records obtained for the two 

 years, 1916-17 and 1917-18.
