Rye has been pastured every year since 1915. The detailed results 
are given in Table 1. The average pasture period was from May 14 
to July 4, a period of 51 days, for an average of 10.2 pigs per acre. 
These pigs with an average initial weight of 1,104 pounds gained an 
average of 279 pounds, or 0.58 of a pound a day for each animal. 
Corn averaging 1,228 pounds was fed to supplement the pasture. 
This averaged 4.42 pounds of corn for each pound of gain.

1 One of these pigs was pregnant during the pasture season. A weight equal to the average of the other 
nine is taken for this animal in the above calculations. 
2 At the end of 61 days one pig was removed because of pregnancy. A weight equal to the average of the 
other five is used for the removed animal in these calculations. 
The average yield of rye on the check plat was 10.4 bushels per 
acre. 
Peas were pastured every year since the experiments were started 
except in 1921, in which year the crop was destroyed by hail. As tke 
work in 1915 was of a preliminary nature and the pasture was not 
continuous with the other crops in the rotation, the results for that 
year are not considered in the assembled data, which are given in 
Table 2.
