We have previously noticed and called attention to this same 

 subject. Dr. Babcock also presents data in the 12th annual 

 report of the Wisconsin Station showing the effect of insufficient 

 food upon the composition of milk. 



If the factory cows had been supplied with an abundance of 

 nutritious, succulent food, the season's yield of milk would have 

 been greater, the percentage of decrease after May being much 

 less; and, in addition, the cheese-producing efficiency would have 

 been greater than it was. If the percentage decrease in yield 

 of milk had been the same in the case of the factory cows as in 

 the case of our Station herd, the yield of milk would have been 

 materially greater than it was, and we can calculate what this 

 increased yield should have been, if the condition of the factory 

 cows had been entirely normal. We can also calculate how 

 much more cheese would have been produced under normal con- 

 ditions. Below we present data showing the amounts of milk 

 and cheese actually produced and then the amounts which would 

 have been produced if the milk had undergone in yield and com- 

 position only such changes as come normally with the advance 

 of lactation. 



If the yield of milk had not fallen ofif more rapidly than in 

 the case of properly fed cows, the factory cows would have pro- 

 duced during the season about 360,000 pounds more milk than 

 they did, and this would be equivalent to about 42,000 pounds of 

 cheese, which at normal prices would be worth over three thou-
