At the beginning of the experiment, samples of the milk 

 were taken daily, but it was finally decided to make a com- 

 posite sample of three days' milk (Monday, Tuesday and 

 Wednesday) of each week, believing that in this way a 

 better knowledge of the composition of the milk produced 

 by the various cows could be o])tained. 



Did the Coarse Fodders Influence the Quality of the 3Iilk f 



By the quality of the milk the percentages of total solids 

 and of fat are referred to. A close study of the analyses of 

 the milk in the various periods leads to the conclusion that 

 the different coarse fodders exerted no decided influence 

 upon the composition of the milk. There were variations 

 from week to week, both in the percentage of total solids 

 and of fat, but no marked change is noticed in any one par- 

 ticular period, and the slight variations that do occur should 

 without doulit be attributed to the condition of the animal, 

 and the consequent influence u})on the secretion, rather than 

 to any particular influence due to the feed consumed. 



General Conclusions. 



This experiment confirms others made at the station, and 

 points out the economy of raising and feeding a greater 

 variety of coarse fodder articles, sul)stituting them for the 

 high priced hay. 



Corn and soja-bean ensilage has proved itself to be fully 

 equal if not superior to hay in producing a yield of milk, with- 

 out aftecting the quality and at the same time decreasing the 

 absolute cost. This ration produced milk at less than two 

 cents per quart. 



Roots, while they are beneficial to the health of the ani- 

 mals, especially those fed upon dry fodder, cannot ])g fed to 

 any extent economically, because of the increased cost of the 

 milk produced. 



Hay of peas and oats proved itself to be nearly or quite 

 equal to a good quality of rowen for milk production. 



The different coarse fodders have not influenced the com- 

 position of the milk to any noticeable extent.
