Vernois gives the results of dry and succulent food on the amount 

 of the different proximate principles in the milk. 



Nature of Food. 



Cows on winter feed : 



Trefoil or lucerne 12-13 lbs. ; 

 oat straw, 9-10 lbs. ; beets, 



7 lbs. ; water, 2 buckets 



Cows on summer feed : 



Green trefoil, lucerne, maize, 

 barley, grass and 2 buckets 



water §59-56 



Goats milk on different rations: 



Straw and trefoil, 858.68

The decrease of the solids but especially of the ca.sein, sugar, 

 and salts is very marked in the cow on poor winter feeding. In 

 the goat fed on beets alone the increase of sugar and decrease of 

 other solids is striking. 



To the same effect speaks the following table giving the results 

 of an experiment with a ration of corn and cob meal, in contrast 

 with one of sugar meal. Each cow had a common ration of 

 12 lbs. corn fodder and 4 lbs. clover hay, in addition to the test 

 diet which was 121^ lbs. corn and cobmeal in the one case, and 

 10 lbs. sugar meal in the other. To avoid the mi.sleading effects 

 of a sudden transition from one food to the other, each special 

 ration was fed for seven days before the commencement of each 

 test period.
