results. It therefore seems best to present the details of the experi- 
ment year by year. This allows opportunity for brief discussions of 
the seasons and explanation of apparent deviations or omissions from 
the outlined program. . 
The pasturing work in 1915 was of a preliminary character and was 
confined to the rotation of annual crops. The land used was broken 
from native sod the previous fall and all the crops were planted in 
the spring. This being the case, White Smyrna barley, a bearded 
variety, was used in place of winter rye. The season was cool, the 
rainfall was abnormally heavy, and all crops made yields considerably 
above the average. The hogs used were fall pigs of the Duroc-Jersey 
and Poland China breeds and were borrowed from neighboring 
farmers for the work. 
Nine hogs, totaling 1,366 pounds, were placed on July 14 on the 
plat of White Smyrna barley, where they remained until July 30, a 
period of 16 days. At the time the pasturing began the barley was 
in the soft-dough stage. From the actions of the animals and the 
small gains made it was readily seen that the crop was unpalatable 
‘because of its beards, and the hogs were removed to the plat of 
Success barley. While on the White Smyrna barley a total gain of 
only 40 pounds for the lot was made. The check plat of this crop 
yielded 43.8 bushels of thrashed grain per acre. 
Seven fall pigs having a combined weight of 986 pounds were put 
on the plat of peas on July 17, when the grain was in the dough stage, 
and remained on it until August 3. During this period of 17 days 
the lot made a total gain of 280 pounds, or about 2.4 pounds per pig 
per day. The check plat yielded 8.4 bushels of thrashed peas per 
acre, but as much of the grain was lost by shelling out durmg 
harvest the actual yield was somewhat higher. No supplementary 
ration was fed with the peas. 
The plat of Success barley was stocked on July 17 with eight pigs 
weighing 1,224 pounds. On July 30 the nine pigs from the White 
Smyrna barley plat were added. At this time these pigs weighed 
1,406 pounds. 
The total lot of 17 pigs was removed from the Success barley plat 
on August 11. Thus, the crop carried eight pigs for a period of 25 
days and nine pigs for a period of 12 days. - The first lot of eight pigs 
made a total gain of 129 pounds, or an average daily increase of 0.65 
of a pound each. The lot of nine pigs added on July 30 made a total 
gain of 90 pounds, or 0.83 of a pound per pig perday. The harvested 
plat yielded 33.2 bushels of grain per acre. 
The plat of corn was harvested by 10 spring pigs weighing 1,115 
pounds. This lot was placed on the corn on September 29 and 
remained there until October 24. A total gain of 480 pounds was 
made in the 25-day period. This is 1.92 pounds a day for each pig. 
One of the animals suffered from rheumatism toward the last of the 
season and did not gain as rapidly as the others. The plat of corn 
husked out by hand yielded 33 bushels of grain per acre. 
The experience of 1915 was valuable in working out the relationship 
these crops have to one another in regard to cultural methods, growth, 
season of pasture, and palatability. Methods of handling the hogs 
and the technic in regard to taking the individual weights were also 
developed.
