CDT 21.— CARBOHYDRATE REQUIREMENT OP MARKET PIGS. 



Carbohydrate Requirement. — The above cut shows the 

 amount of digestible carbohydrate required by pigs that 

 are being fed for market. It will be noticed that pigs 

 from the third to the sixth month of age, inclusive, 

 should have from 2.4 to 2.8 pounds of digestible carbo- 

 hydrate daily per hundred pounds of live weight. Dur- 

 ing the last eight weeks of the feeding period the pigs 

 may be put on nearly full feed on a ration that is pri- 

 marily carbonaceous in nature. Pigs with a low degree 

 of vitality cannot take this much. 



Pigs intended for breeding purposes should have less 

 carbohydrate than those that are fed for market, as 

 shown in the cut inserted below : 



CDT 21A.— CARBOHYDRATE REQUIREMENT OP BREEDING PIGS. 



The latter part of this curve as well as the latter parL 

 of the protein curve showing the protein requirement of 

 breeding pigs have not as yet been as thoroughly worked 

 out as the other points mentioned, but are believed to be 

 essentially correct.
