198 RESULTS OF EXPERIMENTS IN SWINE FEEDING 
pastured after the corn is harvested. The Mississippi Ex- 
periment Station (Bulletin 100) reports producing from 350 
to 483 pounds of pork from an acre of cow-peas. The peas 
were allowed to become nearly ripe before the hogs were turned 
in. (Also see Missouri results reported in this chapter. ) 
Soy Beans vs. Cow-peas.—Bulletin 82 of the Tennessee Sta- 
tion makes the following comparisons: 
The soy bean may fail to come through a crust which would 
offer but little resistance to cow-peas. 
The germination of the cow-pea seed is surer than that of the 
soy bean seed. The cow-pea is, therefore, better than the soy 
bean for broadcasting, especially on land that is heavy and 
liable to bake. 
The cow-pea is much better suited than the soy bean for 
planting with either corn or sorghum. 
On the other hand, the soy bean is more valuable than the 
cow-pea as an early grazing crop, and the seeds decay more 
slowly than those of the cow-pea when left on the ground, which 
is an advantage when the crop is to be pastured off by hogs. 
It will be seen, therefore, that much depends upon the condi- 
tions under which the crop is grown. 
Mixtures.—Various mixtures have been used as pasture 
crops for swine. The writer has used oats and peas, also a 
mixture of oats, peas, and vetches. These crops do not stand 
pasturing well, and are better suited for soiling purposes. 
The Michigan Experiment Station speaks well of a mixture 
of corn, peas, oats, rape, and red clover. There is a good deal 
of waste in pasturing this crop. If, however, the first crop 
could be cut for soiling purposes, the second growth would 
furnish a good deal of pasture. (See also Missouri tests re- 
ported in this chapter.) 
Jerusalem Artichokes.—The Central Experimental Farm, 
Canada, reports good results from this crop. One-sixteenth of
