ALFALFA FOR DAIRY COWS. 389 
purchased feeds average $25 per ton alfalfa is worth 
$16.50 to feed with corn 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 than 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.
