The prime obiect in planning the feeding experiments re 

 corded in this Bulletin was to determine as far as possible the 

 actual feeding value of the ensilage produced from the different 

 varieties of corn described in Bulletin No. i, and incidentally 

 to note the cost of a quart of milk or a pound of butter with the 

 various rations used. 



The animals experimented on were a mixed herd of young 

 and mature cows in various stages of lactation, from fresh in milk 

 to six months after parturition. Plalf of the herd had been 

 bought from farmers and were native cows, there were four heif- 

 ers with their first calves, and the" remainder were thoroughbred 

 Shorthorns. Taking all together they were a fair lot of cows, 

 weighing at beginning of experiment an average of 948^ 

 pounds. 



The kinds of fodder and grain used were corn fodder or 

 stover, bean vines, mixed hay containing a large proportion of 

 alsike and red clover, millet cut when seed was fully formed, 

 mixed grain consisting of ninety pounds of northern corn 

 ground together with the cob, and twenty-five pounds of oats, 

 gluten meal from the Chicago Glucose Works, buckwheat 

 ground with hulls not separated, and clear corn meal ground 

 from northern corn. 



Lack of means and help prevented the analysis of part of 

 the materials used, but the best average results of analyses of 

 other years was taken as a guide to- the composition of the ra- 

 tions used. The ensilage was analyzed, giving the following 

 results, as taken from Bulletin No. i :
