Feeds and Feeding. 



The amount of milk and fat produced was practically the same for 

 both rations, showing the high value of crimson clover hay and cow- 

 pea silage as sources of protein for dairy cows. 



678. Cowpea hay. At the New Jersey Station 1 Lane alternately 

 fed 2 lots of 2 cows each rations containing either cowpea hay or rich 

 purchased concentrates for periods of 15 days, with the results shown 

 in the table: 



Cowpea hay compared with purchased protein. 



Tho 2 Ibs. more milk and 0.13 Ib. more fat were produced by each 

 cow daily on the ration containing purchased concentrates, this in- 

 crease was not sufficient to offset the greater cost of the purchased 

 feed. (261) 



679. Cowpea hay v. wheat bran. At the Alabama Station 2 Dug- 

 gar fed 2 lots of 3 cows each cotton-seed hulls and a basal ration of 2 

 parts cotton seed and 1 part each of wheat bran and cotton-seed meal. 

 In addition the cows in Lot I received cowpea hay and those in Lot 

 II wheat bran with the results shown below:

In this trial the cows getting the cowpea hay averaged 1.3 Ibs. 

 more milk daily than those fed wheat bran, showing that where there 

 is a fair supply of rich concentrates it is more economical to com-
