 course of the experiment was less than one hundred pounds. 



THE EFFECT OF GRAIN WHEN COWS ARE SOILED. 



Beside the experiment detailed above a similar one was carried 

 on at the same time in which the cows were kept in the barn, and 

 the grass cut and carried to them. For this experiment there 

 were also two lots of three cows each, but the only cows available 

 were those that had been in milk during the winter, and were due 

 to calve again in the early fall. The lots were as follows : 



LOT III — SOILED ON GRASS. 



No. i — Puss, Y% -blood Holstein, five years old; dropped last 

 calf Sept. 22, 1889; bred Nov. 8, 1889. 



No. 2 — Aggie, "/s -blood Holstein, six years old ; dropped last 

 calf Sept. 25, 1889; bred Nov. 8, 1889. 



No. 3 — Pet, }i -blood Holstein, four years old ; dropped last 

 calf Aug. 29, 1889; bred Dec. 11, 1889. 



LOT IV — SOILED ON GRASS AND GRAIN. 



No. i — May, ^ -blood Holstein, eight years old ; dropped last 

 calf Oct. 4, 1889; bred Jan. 12, 1890. 



No. 2 — Belva, ^ -blood Holstein, three years old ; dropped last 

 calf Sept. 8, 1889; bred Nov. 7, 1889. 



No. 3 — Freddie, ^ -blood Holstein, four years old ; dropped last 

 calf Sept. 14, 1889; bred Dec. 5, 1889. 



The experiment was begun on May 25th, up to which time both 

 lots had been fed on ha3^ and the same amount and kind of grain 

 that Lot IV continued to receive, and lasted for five weeks. 

 Each cow had furnished to her all the fresh cut grass, clover and 

 timothy in about equal proportions, she would eat, in two feeds 

 per day, and the cows in Lot IV had in addition 9 pounds each 

 per day in two feeds of the same grain mixture that was fed Lot 

 II, viz.: 200 pounds wheat bran, 150 pounds cotton seed meal, 

 and 15 pounds malt sprouts. The other details of the experiment 

 were carried out in the same manner as for Lots I and II. 



In table V is shown the results of the feeding, in milk and butter :
