DRY-LAND PASTURE CROPS FOR HOGS. 91 * 
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.

1G. 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 in 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.
