, ALFALFA FOR DAIRY COWS. 389 



purchased feeds average $25 per ton alfalfa is worth 

 $16.50 to feed with com silage. 



At the New Jersey station a test was made with 

 two lots of dairy cows to determine the compara- 

 tive value of alfalfa and a combination of wheat- 

 bran and dry brewer's grains as a source of protein. 

 In this test the alfalfa ration produced a daily yield 

 of 20.8 pounds of milk and 1.06 pounds of butter, 

 while the bran and brewer 's-grain ration produced 

 a daily yield of 21.8 pounds of milk and 1.08 pounds 

 of butter, only a slight difference in favor of the 

 more concentrated protein foods. Bran and dried 

 brewer's grains each cost $17 per ton, on which basis 

 alfalfa hay proved to be worth $11.16 per ton. 



At the Maryland station alfalfa and cornmeal 

 gave better results thaii silage and commercial 

 foods. Where alfalfa and silage were fed with and 

 without grain, the grain feeding proved the more 

 economical. 



Experiments conducted at the Tennessee experi- 

 ment station tend to show that one and one-half 

 pounds of alfalfa will replace one pound of wheat- 

 bran. 



The New Jersey station concludes that three 

 pounds of alfalfa is equivalent in feeding value to 

 one pound of cottonseed-meal. 



The Nebraska station compared feeding alfalfa 

 hay with the feeding of prairie hay, and decided as 

 a result of these tests that alfalfa produced 10 per 

 cent more milk from 10 per cent less food.
