212 HOW TO FEED SILAGE. 



furthermore. In most cases, be ground, costing ten cents or more 

 a bushel of 70 lbs. The advantage Is, therefore, decidedly with the 

 siloed fodder in economy of handling, as well as in the cost of 

 production. 



The comparative feeding value of corn silage and fodder corn 

 has been determined in a large number of trials at different experi- 

 ment stations. The earlier ones of these experiments were made 

 with only a couple of animals each, and no reliance can, therefore, 

 be placed on the results obtained In any single experiment. In the 

 later experiments a large number of cows have been included, and 

 these have been continued for sufficiently long time to show what 

 the animals could do on each feed. 



Comparative Cost of Producing Silage. — The Oregon Agricul- 

 tural College Bulletin No. 136, comparing the total digestible nu- 

 trients of silage with other succulent feeds based largely on figures 

 from Henry's "Feeds and Feeding" shows that one ton of com 

 silage is equal to 1.0 ton of artichokes, 1.4 tons of parsnips, 1.5 

 tons of sugar beets, 1.8 tons of rutabagas, 1.8 tons of carrots, 2.2 

 tons of turnips, 2.4 tons of mangels, or 2.3 tons of kale. These 

 figures do not take into consideration the palatability or the stim- 

 ulation on milk, secretion that any of these feeds might exert.
