It is evident that peanuts afforded a much softer lard 

 than did sorghum, even when each constituted only 

 about half the ration. The feeding of somewhat less than 

 a half ration of mixed cotton seed meal and corn meal 

 (1 to 4) for five weeks while peanuts were 

 being gTazed, failed to overcome the softening effects of 

 peanuts. 



In two experiments already recorded in this bulletin 

 the body lard from pigs getting only peanuts melted at 

 temperatures of 74.6 aud 71. G degrees Fahrenheit; the 

 feedinof of a small amount of a mixture of cotton seed 

 meal and corn meal for five consecutive weeks while 

 peanuts were being eaten in this test raised the melting 

 point to 87.4 degrees, a gain of 12.8 and 15.8 degrees. 



This increase o^.l2.8 to 15.8 degrees in hardrffiss is 

 somewhat greater *than had previously resulted ^rom 

 feeding a stronger cotton seed meal mixture for .six 

 weeks after the peanuts wer^. di^contined (see Experi- 

 ment on p. 29. ) .^ ^.," 



On the whole the^e experiments viewed together in- 

 dicate that greater hardening effect results from the 

 grain whem fed with the softening food (as 

 peanuts or chufas) thau from that fed as the exclusive 

 ration in the six weeks just before the date of bi^tcher- 

 ing. This is also practically the conchision reached by 

 Bennett in Arkansas Bulletin No. 65. I
