16 AGRICULTURAL EXPERIMENT STATION. [Jan. 



various feeding periods, the daily diet of the cows, varied on 

 that occasion from 1: 6.7 to 1:10. 17. The closer relation 

 was obtained by feeding on an average, daily, — 



3\ lbs. of wheat bran, ") 



15 lbs. of hay, v Nutritive ratio, 1 : (5.7. 



40 lbs. of Lane's sugar beet, ) 



And the wider ratio by feeding daily on an average, — 



3} lbs. of corn meal, '\ 



5 lbs. of hay, V Nutritive ratio, 1 : 10.17. 



41| lbs. of corn ensilage, J 



(See Daisy.) During our more recent feeding experi- 

 ments described below, on the whole, closer relations are 

 adopted than before. The relations between the two above 

 stated important groups of fodder constituents vary from 

 1 : 5.9 to 1 : 7.9 ; they are also more uniform during the 

 various feeding periods. The closer relation is obtained by 

 feeding daily on an average, — 



3^ lbs. of corn meal,* ^ 

 3^ lbs. of wheat bran,* 

 3^ lbs. of gluten meal, 

 10 lbs. of hay, 

 35 lbs. of carrots.

3 1 lbs. of corn meal, ") 



3|- lbs. of wheat bran, y Nutritive ratio, 1 : 7.9. 



25 lbs. of hay, ) 



(See Dora. ) The entire recent feeding experiment (I. ) is 

 subdivided into eight distinctly different feeding periods ; the 

 same number as on the preceding occasion, for the same 

 lenofth of time, — seven months. 



The dry corn fodder, the ensilage and the roots were cut, 

 before beins: offered as feed. The exact amount consumed 

 of each fodder article was ascertained by taking their weights 

 before feeding and deducting the amount left, if any. Grain 

 and roots were usually fed during milking, and the coarse 

 fodder between times. 



* 3^ lbs. of wheat bran is equal to four quarts ; and 3^ lbs. of com meal ii equal 

 to two quarts.
