PASTURE AND SOILING CROPS 191 



cut and carried to the pigs. The pigs were fed meal and 

 skim-milk in addition. 



An acre of rape furnished 22 tons of green fodder, and an 

 acre of soy beans 15 tons of green fodder. 



Soy beans had a higher feeding value per ton than rape, but 

 when the difference in yield was taken into consideration, the two 

 crops proved about equal in amount of pork produced per acre. 



Rape has an advantage over 'soy beans in that it may be 

 sown on a wider range of dates, and retains its green condition 

 for a longer period. 



Rape also makes a better pasture crop than soy beans, as 

 it suffers less from trampling. 



Clover and Timothy. In the experiments at the Iowa 

 Experiment Station with supplementary feeds with corn, .hogs 

 were pastured upon both clover and timothy. Without going 

 into details, it may be said that the experiments indicate that 

 clover produced pork at the rate of 400 pounds per acre, and 

 timothy at the rate of 278 pounds per acre. This is probably 

 more than can be expected from these crops as a general rule. 



Hairy Vetch or Sand Vetch. This crop is very much 

 relished by hogs, and if sown in the fall gives an early pasture 

 of high nutritive value. Smooth vetch is sown in the spring, 

 but it is rather late in the season before it is ready for pasture, 

 and does not give the amount of pasture which is desirable. 

 The liability of hairy vetch to winter-kill in some districts when 

 sown in the fall, and the high price of the seed, prevent the crop 

 from becoming widely popular. 



Various Forage Crops. Bulletin 95 of the Missouri Ex- 

 periment Station reports three years' work with several forage 

 crops. 



Shelled corn and corn meal were used to supplement the 

 rape and the leguminous forage; and a ration of corn meal
