AGRICULTURAL EXPERIMENT STATION". 95 



It is very plain that for young pig the rations containing skimmed 

 milk proved superior to those containing the nitrogenous vegetable 

 foods as a substitute. But with the older animals the substitution 

 of pea meal or pea and oat meal for the skimmed milk, wholly or in 

 part, did not materially change the rate of growth or its relation 

 to the digestible food consumed. 



In a single case an exception occurs, viz : Period 3 with the 

 Berkshires in the 1892 experiment, where the pure grain ration 

 seemed to check the growth of the pigs. In all other cases the 

 amount of digestible food seems to be the practical measure of 

 efficiency whether its source be animal or vegetable. 



WASTE OF FAT IN SKIMMED MILK BY THE 

 DEEP-SETTING PROCESS.* 

 W. H. Jordan and J. M. B^vrtlett. 



The relative economy of the various methods of creaming milk 

 is a matter which is just now receiving much attention from Maine 

 dairymen. The question which is most frequently asked, especially 

 by those keeping a fairly large herd of cows, is, "Shall I get a 

 separator ?" 



In comparing the separator with the cold deep-setting process 

 several points demand consideration : 



1st. The relative expenditure of money, time and labor. 



2d. The relative waste in the skimmed milk. 



3d. The relative waste in the buttermilk. 



4th. The comparative quality of the product. 



Present knowledge leads to the opinion that the cream can be 

 handled with equal economy from the two methods, and that there 

 is not difference enough between well made separator-cream butter 

 and equally well made cold-setting-cream butter to find any prac- 

 tical recognition in the most particular market. 



The first two points, then, are the ones concerning which there 

 is still more or less discussion.
