124 SOUTHERN PORK PRODUCTION 



trates will have to be used, but it is also possible to grow 

 these at low cost, and they can, for the most part, be 

 harvested by the hogs themselves. We can have forage 

 crops every day in the year for our hogs if we plan far 

 enough ahead. 



Rotations. After one has decided upon the crops that 

 can be grown under his conditions, the more important 

 problem of arranging for a rotation or succession enters 

 in. There are no rotations that are applicable all over 

 the South, a specific one being required for each section 

 and farm. In order to show how they are planned, some 

 typical ones are presented. Of course, it will be necessary 

 to have several fields in order to properly graze swine. 

 As a general proposition, the more fields and the greater 

 variety of crops grown the better. It is possible to pro- 

 vide grazing pretty well through the year and feed hogs 

 in a limited way with three fields on a three-year rotation. 

 Such a rotation might be planned about as follows : 

 GRAZING FROM JAN. 1 TO JAN. 1 



Order Approximate order 



planted grazed (months) 



Field 1 Winter grains plus winter legume Mar., June 



Summer legume plus corn Sept., Oct. 



Field 2 Winter grains plus winter legume May, July 



Sweet potatoes plus peanuts Nov., Dec. 



Field 3 Rape plus oats Jan., Feb., Apr., May 



Early corn plus legume Aug. 



A four-field rotation could be made from the above by 

 the addition of a field of alfalfa. A permanent grass 

 pasture, such as Bermuda or blue grass, would also work 

 in well with the above grazing plan, but it should not be 

 rotated. An ideal five-field system would include the 

 above three-field plan, with one field additional for al-
