40 AGRICULTURAL EXPERIMENT STATION. [Jan. 



The results obtained in this connection in previous years 

 have already been published in our previous annual reportSj 

 five, six and seven ; they were considered on the whole in a 

 sufficient degree encouraging to advise a continuation of our 

 investigations in that direction. For details regarding the 

 merits of Southern cow-pea, serradella, vetch, vetch and 

 oats and vetch and barley, as substitutes in part or in the 

 whole of an average English hay and rowen, as coarse fod- 

 der ingredients of the daily diet in case of the same kinds 

 and the same quantities of grain feed, I have to refer to 

 some of our previous annual reports. 



1890. — During our late experiments, July 12 to Septem- 

 ber 30, we used the following fodder articles in the com- 

 pounding of the daily diet : a mixed crop of green vetch 

 and oats, or green soja l)eans, with first and second cut of 

 dried upland meadow growth, English hay and rowen, fur- 

 nished the coarse feed, while corn meal, wheat bran and 

 new-process linseed meal (Cleveland)" served as fine or grain 

 feed. The kind and the quantity of the daily grain feed 

 remained the same during the entire experiment, Lp., corn 

 meal, wheat bran and new-process linseed meal, each three 

 and one-quarter pounds daily per head of cows ; five pounds 

 of hay, with all the green crop the cows would consume, 

 finished the daily diet. The green crops were cut into 

 pieces from six to eight inches long before being fed. One- 

 half of the daily ration of grain feed and of green fodder was 

 fed during milking in the morning, and tlie other half at 

 milking in the evening ; the hay was fed between both 

 meals. The daily quantities of grain and of hay remained 

 the same, both being entirely consumed. The daily con- 

 sumption of the green feed, however, was decided by the 

 appetite of the difterent cows ; vetch and oats varied from 

 fifty to sixty pounds, and soja beards from forty to sixty 

 # pounds. The quantity consumed per day decreased in all 

 cases toward the maturing of the crop, on account of the 

 gradual increase of solid matter in the crop. The follow- 

 ing statement contains the average daily fodder rations per 

 head ; they succeeded each other in the order in which they 

 ^re reported ; —
