White?' feeding experiments (pp. 239-265). — One feeding test was 

 made each winter for -i years. The first test included 9 cows and cov ■ 

 ered 24 weeks, and the remaining tests included -i cows each and 

 covered 16, 19, and 16 weeks, respectively. In each test a comparison 

 was made between alfalfa alone and alfalfa and corn fodder. Different 

 quantities of grain, ranging from 1 to 8 lbs., were fed daily in the 

 different tests. The nutritive ratio of the alfalfa ration was 1:1.6, 

 and of the alfalfa and corn fodder ration 1:6. The results are tabu- 

 lated and discussed. There was a waste of about 10 per cent in feed- 

 ing lucern and 25 per cent in feeding corn fodder. The cows gained 

 slightly in Aveight on the alfalfa ration and lost on the alfalfa and 

 corn fodder ration. 



' ' Calculated from the amount eaten, the ration of alfalfa and corn fodder produced 

 milk and butter fat for a little less outlay in dry matter than the ration of alfalfa, 

 but calculated from the amount fed there was practically no difference. Considering 

 the cost of production, and charging the cows with the amomit fed, the corn fodder 

 ration was a little the more costly, but the difference was small . . . The cost of 

 producing milk and butter fat varied according to the amount of grain fed. The 

 ration containing the smallest amount of grain was the most economical. . . . 

 The wider ratio required less dry matter t(j produce 1 lb. of butter fat, or 100 lbs. of 

 milk." 



SimiiiyiT feeding experiments (pp. 267-305). — One test was made 

 each 3'ear for 1 years to compare soiling and pasturing. In all 9 cows 

 were pastured for al>out 16 weeks and 9 were fed in the stable on soil- 

 ing crops for the same time. The pasture-fed cows produced on the 

 average more milk and fat and made a greater gain in live weight than 

 the cows fed in the stable. The flow of milk, however, was not so 

 evenly maintained during the whole period. 



A comparison was made in 5 experiments of the results obtained 

 from 1 acre of land when the crop was pastured and when it was soiled. 



"One acre of soiling crops furnished feed for 2 cows for 108 days, produced 3,145 

 lbs. of milk and 147.9 lbs. of butter fat, valued at $23.67. One acre of pasture fur- 

 nished feed for 2 cows for 102 days, and produced 4,047 lbs. of milk and 189.8 

 lbs. of butter fat, valued at $30.37. This shows au advantage of §6.50 in favor of the 

 acre of land used as a pasture compared with the same area used for soiling crops. 

 These results are not conclusive, however, for the soiling crops." 



The efl'ect of feeding grain to cows on pasture was studied during 

 4 years. In all 28 cows were used in the tests, 11 of which were fed 

 4 lbs. of grain per head daily. The records of the cows fed grain 

 were compared with those of the cows on pasture alone, for the 4 

 months each summer during which the grain was fed, and also for the 

 4 months following during which all the cows were fed alike. 



"The cows which received grain while on pasture jiroduced more milk and butter 

 fat than those not receiving grain, yet not enough extra to pay for the grain fed. 

 The cows fed the grain on pasture maintained their flow of milk better throughout 

 the milking season than did those not receiving grain, and thus during the fall
