 able ones discarded. By this system of elimination, the production 

 per head has been greatly increased. The herds at present contain 

 practically nothing but high producing animals. 



During the summer months, pasture is depended on to only a 

 slight extent, the summer fodder consisting chiefly of soiling crops 

 and corn silage with a grain ration. The soiling crops usually consist 

 of grasses, and clover including alfalfa, green oats and peas and

corn. Ensilage is much used at almost all times of the year. With 

 these and other coarse foods, the cows are generously supplied, 

 while the kinds and quantities of grain foods given are guaged by 

 the quantity of milk each animal is giving. 



The feeding during the winter varies from that in summer by 

 substituting hay, straw and roots for pasture and soiling crops. 

 The average winter ration found most satisfactory consists of hay 

 5 Ibs., corn ensilage 30 Ibs., roots 10 Ibs., straw 4 Ibs., and meal 7 

 Ibs. per day per cow. The hay is usually clover and timothy; the 

 roots mangels, sugar beets and turnips; the straw oat straw and 

 the meal, 8 parts bran, 3 parts gluten meal and 2 parts oil meal. 



Experiments have taught that the best way to prepare the 

 ration is to cut the oat straw and mix it with ensilage and pulped
