The green feeds that are specified under the head of carbo- 

 hydrate concentrates contain a great deal of water. It is 

 quite evident that if these were fed in large quantities, so that 

 a pig was compelled to take more water than its system de- 

 manded they would become roughages in the sense that the 

 pig would be compelled to take more bulk in the form of water 

 than would normally go with the proper quantity of nutrients 

 other than water. This would have a tendency to distend 

 the capacity of its digestive apparatus. An excess of water, 

 however, would have a detrimental effect upon the pig. 



The liquid feeds specified under the head of nitrogenous 

 concentrates may likewise be considered either as concentrates 

 or roughages. 



The nitrogenous roughages aie given under two subject 

 heads, dry feeds and green feeds. The dry feeds are roughages 

 because of the large quantity of crude fiber they contain. The 

 green feeds also contain the crude fiber but relatively less 

 than the dry feeds because they at the same time contain a 

 large quantity of water. This water plays an important part 

 in the metabolism and may take the place of water that is 

 fed as such in connection with dry feeds.
