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 suffers less from trampling than soy beans. 
Soy Beans.—The test with soy beans and rape referred to 
above was conducted in a northern latitude where rape grows 
to perfection and soy beans do not. In the South, it is quite a 
different question, and the soy bean becomes a most valuable 
pasture crop. Bulletin 154 of the Alabama Station recom- 
mends soy bean pasture very highly. When corn is valued 
at 70 cents per bushel, and soy bean pasture at $8.00 per acre, 
it costs $7.61 to produce 100 pounds of pork on corn alone, 
but when hogs were fed corn on a soy bean pasture, the cost of 
100 pounds of pork varied from $2.59 to $3.17. 
One acre of soy bean pasture afforded grazing for 10 hogs, 
of an average weight of 45 pounds at the beginning of the test, 
for the following number of days: 
When one-fourth of a full corn ration was fed................ 43 days. 
When one-half of a full corn ration was fed.................. 48 days. 
When three-fourths of a full corn ration was fed............... 62 days. 
The total value of pork made on each acre of soy bean pasture 
varied from $25.84 to $39.13, valuing pork at 7 cents per pound, 
and deducting value of corn consumed at 70 cents per bushel. 
These results show the possibilities of soy bean pasture as a 
means of reducing cost of pork production in the South.
