578 EXPERIMENT STATION RECORD. 



3,517 sq. ft. of peanuts, making- again of 21.1 lbs. This was equivalent 

 to a profit of $7.83 per acre. In the author's opinion, owing to an 

 exceedingly dry summer, the yield of peanuts was only about half what 

 it would have been under usual conditions. He believes that pigs 

 under 100 lbs. weight would make pork worth from $12 to $20 on an 

 acre of peanuts, provided they were fed a moderate allowance of corn 

 or corn meal in addition. 



In the third test unhulled peanuts and corn meal were compared. 

 For weeks the 2 lots of pigs used in the previous test and a third 

 lot of the same age and breed were fed the following rations: Lot 1 

 unhulled peanuts and corn meal, equal parts; lot 2 peanuts alone, and 

 lot 3 corn meal. The gains made by the 3 lots were 84, 59.5, and 8.6 

 lbs., respectively. The food consumed per pound of gain by the cor- 

 responding lots was 3.7, 2.8, and 10.7 lbs. The author calculates that 

 when fed peanuts alone the young pigs were able to make a growth of 

 9 lbs. per bushel of peanuts, equivalent to a profit of 27 cts. per bushel. 

 Although the addition of corn to the peanut ration increased the gains, 

 they were produced at a greater cost. The pigs fed exclusively on corn 

 gave very poor returns. In the author's opinion this test shows the 

 bad effects of long-continued feeding of corn alone. 



Feeding experiments with coicpeas (pp. 122-125). — Six Essex pigs of the 

 same litter were divided into 2 lots of 3 each. Lot 1 was fed shelled corn 

 ad libitum, and lot 2 was hurdled on a field of cowpeas and given corn 

 in addition. The test covered 6 weeks and was preceded by a prelimi- 

 nary period of 7 days. At the beginning of the test the leaves of the 

 cowv>eas were all green and only about half the peas seemed mature, 

 although the others had attained full size. While the leaves remained 

 green they were readily eaten. In the latter half of the experiment 

 only the peas were eaten. Both lots of pigs received salt and wood 

 ashes. The lots averaged about 150 lbs. at the beginning of the test. 

 Lot 1 gained 45.2 lbs., consuming 263.8 lbs. of corn, or 5.86 lbs. per pound 

 of gain; and lot 2 gained 122 lbs., consuming 374 lbs. of corn, or 3.07 

 lbs. per pound of gain. Lot 1 grazed over. 7,280 sq. ft. On the basis 

 of the yield from a similar field, this area would have produced 132 lbs. 

 of cowpeas. In other words, 1.1 lbs. of cowpeas were consumed per 

 pound of gain in addition to corn, or a total of 4.17 lbs. of corn and 

 cowpeas. It was calculated that the cowpeas would return $10.65 per 

 acre in pork. This, in the author's opinion, is not a large return, but 

 it should be borne in mind that the land was enriched by the cowpea 

 vines and by the manure from the pigs. 



To compare the value of ground cowpeas and corn with ground corn 

 alone a further test was made with the same pigs. Lot 1 was continued 

 on an exclusive corn ration and lot 2 was fed ground corn and ground 

 cowpeas 1:1. The test covered 70 days and was preceded by a prelim- 

 inary period of 7 days. Lot 1 gained 68 lbs., consuming 518.2 lbs. of 

 corn, or 8.06 lbs. per pound of gain. Lot 2 gained 108 lbs., consuming
