During the first four weeks both cows received the beet pulp ra- 

 tion ; during the second four weeks, the corn meal ration, and during 

 the third four weeks the beet pulp ration. The first week in each 

 period was preliminary and the results are not included. The aver- 

 age results of the first and third periods are compared with those of 

 the second period.

The method of caring for, feeding and weighing the animals, and 

 of sampling the feeds and milk was the same as in previously repor- 

 ted experiments. (See Bulletin 94, pages 6 and 7.) 



Character of the Feeds. The silage consisted of I'ride of the North 

 corn and medium green soy beans, grown together in the same row. 

 Owing to the cool summer of 1903, the yield was light, 8 tons to the 

 acre, and both plants were immature when harvested, and the beans 

 unevenly distributed. The silage was fairly good and showed a rel- 

 atively high protein percentage (2.13) which might be expected from 

 immature plants. The rowen analyzed well, but had been somewhat 

 injured by wetting. The Ajax Flakes (a brand of distillers' grains) 

 were a little low in protein (29.07 per cent) but bulky and generally 

 satisfactory. The character of the molasses-beet-pulp has been 

 already described. It was bulky and eagerly eaten. The corn meal, 

 though a trifle below the average in protein, was free from mould 

 and of good quality.

(Pounds.) 



The daily rations were eaten clean and were considered sufficient 

 for each cow. The quantity needed was based upon the size of the 

 animal, milk yield, and ability to consume and utilize food. Red II. 

 received daily 5 pounds more silage, 1 pounil more rowen and i 

 pound more Ajax Flakes than Pearl. The 5 pounds of molasses-
