It is seen that when fodder corn replaced nearly one-half the alfalfa 

 hay, about as good returns were secured as when alfalfa hay alone 

 constituted the roughage. These trials show that where corn and 

 alfalfa flourish, both should be used rather than alfalfa alone. (245) 



673. Alfalfa meal v. wheat bran. Hills of the Vermont Station, 1 

 on substituting alfalfa meal (ground alfalfa hay) for the same weight 

 of wheat bran, found a loss of from 3 to 6 per ct. in milk flow caused 

 thereby, and Mairs of the Pennsylvania Station 2 found a loss of about 

 5 per ct. by such substitution. (248) 



674. Soybean, cowpea, and Japan clover hay. At the Tennessee 

 Station 3 Price compared soybean straw and ground soybeans, com- 

 bined in the same proportion as in soybean hay, with alfalfa hay in 

 a trial with 2 lots of 4 cows each. The returns from rations alter- 

 nately fed during 3 periods of 30 days each are shown below: 



Soybean hay v. alfalfa Inay. 



The table shows that the soybean ration proved more effective than 

 the alfalfa-hay ration. Price concludes: "A ton of soybean hay 

 that can be produced (in Tennessee) for $7 has a higher feeding 

 value than a ton of alfalfa hay." 



Wing of the Georgia Station* found that cowpea hay produced 30 

 per ct. more milk than cotton-seed hulls, a reasonable result when the 

 composition of the two is considered. 



Lloyd of the Mississippi Station 5 reports Japan clover hay prefer- 

 able to timothy hay. (201)

 EXPENSIVE CONCENTRATES OF THE RATION. 



675. Alfalfa hay. At the New Jersey Station 6 Billings alter- 

 nately fed 2 lots of 4 cows each for two 30-day periods as follows: 

 One lot received 40 Ibs. corn silage, 7 Ibs. corn stover, and 11 Ibs. of
