546 Report of the Department of Animal Husbandry of tub 



The preliminary feeding began February 25 and the experi- 

 ment was concluded on May 10. This time was divided into 

 two periods, and the ten cows into two lots. During the first 

 period Lot 1 was fed Ration No. 1 and Lot 2 Ration No. 2. In 

 the second period this order was reversed. All the necessary data 

 were recorded, such as the weights of foods, the weights of the 

 animals and the weight and composition of the milk. The com- 

 position of the foods and the digestibility of the rations have been 

 stated on previous pages. 



The maximum rations fed were those previously given: 



Constituents and Amounts of Rations Compared. 



Ration No. 1. Ration No. 2. 



Timotliy hay 5 pounds. 15 pounds. 



Corn silage 40 pounds. 25 pounds. 



Oats, ground 5 pounds. 



Peas, ground 6 pounds. 



Malt sprouts, dried 2 pounds. 



Brewer's grains, dried 3 pounds. 



Buffalo gluten feed 3 pounds. 



These rations, as before stated, were modified in quantity to 

 suit the needs of the different animals, the proportions of the sev- 

 eral materials being maintained unchanged. 



Without stating the data in full detail, we give herewith the 

 important part in a condensed form, showing the amount of each 

 food and of the digestible matter which each cow ate and the 

 yields of milk and milk solids.
