Tests with Feeding Stuffs. 



417 



hay and 50 Ibs. of wheat bran, produced 100 Ibs. of milk. The cows 

 produced more milk on the bran-alfalfa ration, but the increase was 

 dearly purchased. The findings of Soule of the Tennessee Station 1 

 confirm the above results. 



Hansen of the Royal Agricultural Academy, Germany, 2 on feeding 

 40 cows 140 days, found that 800 to 933 Ibs. of green alfalfa equaled 

 100 Ibs. of sunflower seed cake in feeding value, with cows pastured 

 a portion of the day or wholly confined to the stable. (709) 



676. Crimson clover hay. At the New Jersey Station 3 Lane fed 

 2 lots, each of 2 cows, for 2 periods of 12 days each, alternately on 

 the rations shown below: 



Crimson clover hay fed against purchased protein. 



The table shows that the yield of milk was 3.7 Ibs. and of fat 0.15 

 Ib. less on the crimson clover ration than on that containing pur- 

 chased concentrates. Using the home-grown ration, however, effected 

 a saving of 18.3 cents in the cost of producing 100 Ibs. of milk. (257) 



677. Crimson clover hay and cowpea silage. Lane* also compared 

 a ration of crimson clover hay, cowpea silage, and corn-and-cob meal 

 with one in which the crude protein was largely purchased. The fol- 

 lowing rations were fed alternately for 2 periods of 12 days each to 

 2 lots of 2 cows each: 



Crimson clover hay and cowpea silage compared with purchased protein.
