﻿DRY-LAND PASTURE CROPS FOR HOGS. 



21 



gain in height of the figure represents the gain in hog weights above 

 the first weight of the season. Thus, in 1917 the pigs were placed on 

 the rye plat on May 11 and increased steadily in weight until at the 

 end of the barley period, August 22, a total gain of 497 pounds had 

 been made. The rise of peas above rye shows the gain made on peas, 

 and the rise of barley over peas indicates the gain made on barley. 



Besides the increase in weight for each crop, the diagram shows the 

 period during which each crop was pastured.

(?ig. 2. — Diagram showing graphically the period in each year during which pigs were on alfalfa in rows and 

 alfalfa sown broadcast and the gains made on each pasture and between weighings. 



The data obtained on the alfalfa pastures are presented in Table 

 5 and shown graphically in Figure 2. This has been reduced to an 

 acre basis for each year. Some preliminary pasturing was done 

 with fall and spring pigs on alfalfa, but the data given m the table 

 and the figure are for the years from 1918 to 1921, inclusive. During 

 these years the average number of pigs used was 5 for the row plat 

 and 6.8 for the broadcast plat. Both plats had the same pasture 

 period, averaging 56 days from May 16 to July 11.
