Corn Substitutes for Grovdng Pigs 309 



much fiber to be satisfactory. Chemical studies have 

 indicated, also, that the kind of proteins and ash or 

 mineral ingredients contained in corn by-products gen- 

 erally are not of a nature most efPectively to balance 

 the deficiencies of corn itself. 



PEANUTS 



Peanuts are a valuable hog forage crop in the South. 

 (See Chapter XVIII.) The seed when fed alone, however, 

 produces very soft pork which is sharply discriminated 

 against by the packer. The use of peanuts for the 

 production of oil has largely developed in recent years, 

 and has resulted in two by-products which promise con- 

 siderable value for pork-production, especially in the 

 South. These are peanut oil meal and unhuUed peanut 

 oil feed. Peanut oil meal is merely the hulled and ground 

 peanut minus most of the oil. Unhulled peanut oil feed 

 is the unhulled and ground peanut minus the oil. The 

 latter sometimes goes by the name ground whole pressed 

 peanuts. 



Peanut oil meal as a supplement to milo. 



At the Texas Experiment Station, Burk ' studied the 

 value of these peanut by-products when fed as supple- 

 ments to milo chop to fattening pigs in the dry lot. The 

 peanut meal contained 42 per cent protein, about the 

 same as cottonseed meal, and 8.3 per cent fiber. The 

 ground whole pressed peanuts contained 36 per cent 

 protein and 22 per cent fiber. The rations were hand- 

 fed and the quantity of the mixed ration given was gov- 

 erned by the appetite of the pigs. The results are shown 

 in Table CXLVII.
