Experiment II. — AVinteu, 1904. 



Object of the Experiment. — The object of this experiment 

 was quite similar to the one already described ; namely, to 

 see if corn silage could not be employed in i)lace of Avheat 

 bran as a distributer of the heavy concentrates. 



Plan of the Experiment. — This experiment was conducted 

 on the reversal ^dan. The cows Avere divided into two lots 

 of four each. In the first half of the experiment one lot 

 received the so-called bran ration at the same time the other 

 lot received the silao;e ration. In the second half these con- 

 ditious were reversed. 



Duration of Exjieriment. 



First Half. 



Care of Animals and of the Product. — The general care 

 of the animals and the method of feeding and of sampling 

 the milk have been described in the preceding experiment. 

 Each cow was weighed for three consecutive daj^s at the 

 beginning and end of each half of the experiment, the weigh- 

 ing being done in the afternoon before feeding and watering. 



Character of the Feeds. — The weights of a quart of the 

 two grain mixtures were about the same as those fed in the 

 former experiment, the bran ration being much the more 

 bulky. The bran was derived from winter wheat, and was 

 light and flaky. Corn meal was used in place of corn and 

 cob meal, the latter not being available. The cotton-seed 

 meal and flour middlings were of the usual good quality.
