GRAZING AND FEEDING EXPERIMENTS WITH 



PIGS. 



By J. F. DuGGAR. 



Summary. 



Pigs maide a more economical growth just after wean- 

 ing than (lid sow and pigs just before weaning time. 



The following plants were tested as hog food, the 

 hogs doing the haiTesting; these plants are available 

 for use in the months indicated: 



Spanish peanuts, August to December. 



Chufas, November to March. 



Cowpeas, July to November. 



Sweet potatoes, August to November. 



Sorghum, July to November. 



Vetch and oats, March, April and May. 



Dwarf Essex rape (spring sown), May and June, 



Dwarf Essex rape (fall sown), December, January, 

 Febi*uary, March, and part of April. . 



In most cases it was necessary to feed, in addition 

 to the above crops, from one- fourth to one-half of the 

 usual ration of grain. If we assume that of this grqin 

 5 pounds was required to produce one pound of in- 

 crease in live weight, we have left the following amount 

 of growth of shoats attributable to onie acre of each 

 crop after deducting the gains due to the grain con- 

 sumed. 



Peanuts (with grain) in 7 tests averaged 333 pounds 

 of growth, now worth |16.65. 



Peanuts alone in 2 tests averaged 281 pounds, worth 

 114.05.
