Influence of Food on Milk.

however, was continued till September 1st, after which the cows 

 only got what apple pomace they would eat besides the very 

 scant pasture. The cows were brought to the University early 

 in November, 1900. They were then dry and very thin. Dur- 

 ing the winter they were given as much ensilage and hay as 

 they would eat and 6 lb. of grain daily. As soon as they 

 freshened, which was in most cases in March and April, the 

 grain ration was increased, till each cow was getting all she 

 would readily consume, and this was continued the whole season, 

 both in the stable and on pasture, till the flow of milk 

 diminished. The amount given was in most cases 12 lb. per 

 day, though one cow ate 14 lb. per day, for three months 

 The foods used were cottonseed meal, wheat bran, gluten feed, 

 buckwheat, middlings, and linseed oil meal. While the cows 

 were dry, between the second and third periods, they were given 

 hay and ensilage, but no grain. In the third lactation period 

 they were fed much as they were in the second period as to 

 kind and combination of food, the chief change being that in 

 the latter part of this period malt sprouts formed a considerable 

 part of the grain ration. The amount of grain, however, was 

 materially reduced, the idea being that the food given should 

 bear some relation to yield of milk ; 8 lb. per day was the 

 maximum, except for one cow that was given 10 lb. a day, 

 for about a month. In the fourth period, when the cows were 

 returned to the farm, they were fed practically the same as in 

 1900. The pasture, however, was very much better because of 

 abundant rains, and no grain was given after July 1st. 



The average percentage of fat in the milk of each cow 

 in each season was as follows : —
