548 Feeds and Feeding. 



clover. From numerous trials Carlyle concludes that with pigs 

 from 4 to 10 months old an acre of good rape has a feeding value 

 equal to 2,436 lbs. of mixed corn meal and wheat shorts, when 

 grazed in combination with those feeds. 



At the Oregon Station^ an acre of rape pasture with no grain 

 produced 154 lbs. of gain with pigs. Grisdale of the Ottawa Ex- 

 perimental Farms^ pastured 60 pigs that finally reached an average 

 weight of 185 lbs. each on 1.5 acres of rape, feeding in addition 

 thereto about 500 lbs. of grain to each pig. At the Alabama Sta- 

 tion^ 1 lot of pigs pastured on rape in summer and another lot 

 pastured in winter required about 300 lbs. of concentrates in addi- 

 tion to the rape for 100 lbs. of gain, showing that the rape saved 

 about 200 lbs. of grain for each 100 lbs. of gain made. (254, 282) 



900. Forage crops at the South. — Bennett of the Arkansas Sta- 

 tion* pastured pigs on red clover, sorghum stalks and seed, and pea- 

 nuts. A sow and 5 suclding pigs were placed in a clover pasture 

 on March 30. On May 13 the sow was removed from the trial. 

 The pigs fed on the clover and sorghum until September 21, when 

 they were turned into a peanut field. On December 2 they were 

 put on corn, remaining on this feed until January 3, when the 

 trial was closed. During the trial the pigs made a total gain of 

 about 1,200 lbs., and grazed 0.25 acre of clover, 0.25 acre of sor- 

 ghum, and 0.60 acre of peanuts — a total of 1.10 acres. 



During this time the following, amounts of concentrates were 

 consumed : 



By sow before weaning pigs 518 lbs. corn and 67 lbs. bran 



By pigs while grazing 280 lbs. corn and 31 lbs. bran 



By pigs wliile fattening .-_ 1,06-i lbs. corn 



Total additional feed given 1,862 lbs. corn, 98 lbs. bran 



Allowing 400 lbs. of gain for the corn fed in this trial, there re- 

 mains 800 lbs. of gain to be credited to the 1.1 acre of clover, 

 sorghum, and peanuts. Such data should go far toward stimulating 

 profitable pork production in a vast region of the South now but 

 little devoted to that industry. (202, 222) 



901. Soilage. — At the Llissouri Station'^ Waters fed 4 lots, each of 

 6 high-grade 48-lb. Poland-China pigs, the ration shown on the next 

 page, for 102 days to determine the value of various green supple- 

 ments to corn. The fresh-cut green forage was fed twice daily. 



It is shown that Lot II, fed green alfalfa, required the least 

 concentrates for 100 lbs. gain, Lot III, fed clover, following close.
