191T] ANIMAL PRODUCTION. 679 



In 1916 corn and ground barley were compared as supplements for alfalfa 

 pasture. Although the one acre of pasture on which these tests were made was 

 severely damaged by wind and hail storms, the results were fairly satisfactory 

 and added strength to the previous years' data which showed that ground barley * 

 is equal to shelled corn as a hog feed. For the entire season the gain from 

 the corn lot was 3,142 lbs., and from the barley lot 2,701 lbs. The corn lot 

 consumed 2.74 lbs. of corn and the barley lot 2.92 lbs. of ground barley for each 

 pound of gain made. When the gains made are figured at 7 cts. per pound and 

 the lots charged $1.07 per hundredweight for corn and $1 for ground barley, the 

 net returns for the one-acre alfalfa pastures were $127.84 where corn was fed 

 and $110.11 where barley was fed. The pasture of the barley lot, however, 

 was more severely damaged by the windstorms and one of the shoats in this 

 lot became sick 28 days after the experiment began and was removed. 



Sows and their litters grazed on alfalfa pasture with 2 lbs. of corn per 100 lbs. 

 of live weight made a gain of 1,285 lbs. and a net return of $57.20 per acre in 

 1916. The average for the five years in these tests, in one of which barley was 

 used instead of corn, was 1,516 lbs. of gain and a net profit of $63.11 per acre. 



In an experiment which lasted two months in 1916 where corn and alfalfa 

 pasture were compared with corn alone in a dry lot for finishing shoats for 

 market, IJ acres of pasture supplemented with 9,677 lbs. of corn produced 

 2,497 lbs. of pork, and 11,300 lbs. of corn on dry lot produced 2,202 lbs. of pork, 

 or a gain of 25.8 lbs. on pasture and 19.5 lbs. on dry lot per 100 lbs. of corn. 



Results in 1916 in hogging corn without supplementary feed showed a gain 

 of 840 lbs. of pork worth $58.80 per acre, or $1.56 per hundredweight for the 

 estimated yield of corn. The average gain per acre in four years of these 

 tests was 882 lbs. of pork worth $61.74 per acre, or $1.52 per hundredweight 

 of the estimated yield of corn. 



[Feeding experiments with pigs], D. T. Gray {North Carolina Sta. Rpt. 

 1916, pp. 23-Sl). — At the Edgecombe substation 18 pigs weighing 87 lbs. each 

 were pastured on 5 acres of soy beans for 60 days. In addition to the pasture 

 they received a small amount of corn and tankage (9:1). As a check 3 pigs 

 were fed a full ration of corn and tankage (9:1) on dry lot. The pigs on soy- 

 bean pasture gained 1.38 lbs. per head daily at a cost of 4.96 cts. per pound of 

 gain and returned a value of $19.25 per acre for the soy beans, the yield of which 

 was below normal. The pigs on dry lot gained 1.28 lbs. each daily at a cost 

 of 5.6 cts. per pound of gain. 



To determine the relative value of peanuts and soy beans as grazing crops 

 for pigs, 1.65 acres of soy beans and 1.72 acres of peanuts were planted in the 

 spring of 1915 at the Pender substation. Nine pigs averaging 112 lbs. each were 

 turned into each field September 16 and given a half ration of corn. The soy 

 beans afforded feed for the 9 pigs for 61 days, but an equivalent area of peanuts 

 afforded grazing only 36 days. The soy bean-fed pigs gained an average of 

 0.98 lb. per head daily at a cost of 5.2 cts. per pound of gain. The peanut-fed 

 pigs gained 1.36 lbs. per head daily at a cost of 5.41 cts. per pound of gain. 

 Deducting the cost of grain the soy beans produced $18.80 and the peanuts 

 $16.61 worth of pork per acre. 



In an experiment to test the relative value of peanuts damaged in the shock 

 and peanut meal for pigs at Edgecombe, 30 pigs averaging 98 lbs. each were 

 divided into three lots and fed for 149 days, beginning January 25, 1916. The 

 pigs in the first lot were fed a ration of corn and shorts (2:1), those in the 

 second lot corn and damaged peanuts (2: 1), and those in the third lot a ration 

 of corn and peanut meal (2: 1). Those in the first lot gained 0.69 lb. per head 

 daily at a cost of 10.35 cts. per pound of gain, those in the second lot 0.71 lb. 

 at a cost of 9.83 cts., and those in the third lot 0.81 lb. at a cost of 8.81 cts.
