DRY-LAND PASTURE CROPS FOR HOGS. 17 
CORN. 
The corn on both the pasture rotation and the harvest rotation 
died of drought before making grain, and no yields were obtained. 
ALFALFA. 
A searcity of fall pigs and the poor condition of the alfalfa pastures 
necessitated using half-acre areas. The areas having the best stand 
of alfalfa were fenced off and used for grazing. Both the broadcast 
and row plats were stocked on May 19 at the rate of six pigs per 
acre. The lot placed on the row plat totaled 772 pounds per acre, 
while that on ie broadcast plat weighed 728 pounds per acre. 
The alfalfa on each plat, though somewhat thinner as to stand than 
desirable, was about 6 inches high and seemed to be making a good 
erowth. Though the season was dry, the crop made continuous 
erazing for a period of 70 days. The pigs were removed on July 28. 
The pigs on the row plat increased 436 pends per acre, or at the 
rate of 1.04 pounds per day each and at the ratio of 1 pound of gain 
to 3.04 pounds of corn. The pigs on the broadcast plat made a total 
gain of 402 pounds per acre, which averaged 0.96 of a pound per pi 
per day. This lot had a ratio of 3.38 pounds of corn fed for eac 
pound of gain. 
No alfalfa was obtained from the check plats because of drought 
BROME-GRASS. 
In order to use areas having fairly uniform stands of brome-grass 
for pasturing, one-half acre of the row plat was used and one-fourth 
acre of the broadcast plat. When the pigs were placed on these plats 
on May 19, the brome-grass averaged 6 inches in height. The stand 
on each plat was thinner than was desirable. 
The row plat was stocked at the rate of six pigs per acre, with an 
initial weight of 732 pounds. The lot on the bea cast plat was at 
the rate of eight pigs per acre, totaling 1,012 pounds. The row plat 
produced continuous grazing for a period of 70 days, but on the broad- 
cast plat the hogs ian to be removed at the end of 62 days. 
A gain of 0.74 of a pound per day for each animal, or 310 pounds 
Per acre for the lot, was made on the row plat, while the individual 
aily average of the pigs on the broadcast plat was 0.9 of a pound, or 
a total of 436 pounds per acre. 3 
Corn fed to the row-plat hogs totaled 1,246 pounds to the acre, or 
4.02 pounds of corn for a pound of gain. The pigs on the broadcast 
plat received an acre total of 1,412 pounds of corn, or 3.24 pounds of 
grain for each pound of gain. 
No yields were obtainable from the check plat of brome-grass 
‘because of the drought. 
The duplicate perennial pastures seeded in 1919 and fallowed in 1920 
were reseeded in the spring of 1921. 
STUDY OF THE RESULTS WITH DIFFERENT CROPS.* 
The data on pasturing the four crops, rye, peas, barley, and corn, 
in the 4-year rotation for the years from 1916 to 1921, inclusive, are 
assembled in four tables, one for each crop. The averages at the 
bottom of each table were determined for the number of years the 
crops were actually pastured, exclusive of 1915. 
‘ For information on the pasturing of irrigated crops with hogs and the feeding of hogs while on pasture 
and in the feed lot, see the published reports of the work of the Huntley experiment farm, Bureau of Plant 
Industry, for the years 1913 to 1921, inclusive, by Dan Hansen, Farm Superintendent.
