Feeds and Feedmg. 



linseed cake of practically equal value for milk production when 

 added to a basal ration of hay, bran, and sugar-beet chips. Tho a 

 daily allowance of 4 to 7 lbs. of soybean cake was fed, no ill effects 

 resulted. (201) 



Lindsey of the Massachusetts Station^ found that soybean meal 

 from which the oil had been extracted did not modify the composi- 

 tion of the milk nor exert a marked influence on the body of the 

 butter. The feeding of soybean oil temporarily increased the per- 

 centage of fat in the milk and produced a softer, more yielding 

 butter. (630) 



In view of the present vast importance of the soybean in the 

 Orient and its rapidly increasing use in Europe and America, these 

 various trials are significant and suggestive. 



644. Wet beet pulp. — Wing and Anderson of the Cornell Station- 

 found that cows will eat 50 to 100 lbs. of fresh beet pulp per day 

 in addition to 8 lbs. of grain and 6 to 12 lbs. of hay. The dry mat- 

 ter in wet beet pulp proved equal to the dry matter in corn silage. 

 The milk-producing value of beet pulp as it comes from the factory 

 is about one-half that of corn silage. Beet pulp may have a higher 

 value than given above if no other succulent food is supplied. The 

 fermented pulp appears to be more palatable and satisfactory, tho 

 even fresh pulp seems to stimulate the consumption of dry rough- 

 age. There are occasional reports of beet pulp tainting the milk. 

 Butfum and Griffith of the Colorado Station^ found 2 lbs. of fresh 

 beet pulp equal to 1 lb. of sugar beets for dairy cows. (309) 



645. Dried beet pulp. — Billings of the New Jersey Station'^ fed 

 2 lots of 2 cows each alternately for two 15-day periods on dried 

 beet pulp and corn silage with other feeds as given below : 



Dried beet pulp compared iviih corn silage. 



It will be seen that, where 9 lbs. of dried beet pulp and 5 lbs. 

 mixed hay replaced 45 lbs. of corn silage, the cows gave 3.4 lbs., or
