rate of approximately 2.3 pounds daily for each 100 pounds of live 
weight. Figure 1 shows the five shotes on alfalfa pasture. 
On July 6, eight spring pigs, weighing a total of 273 pounds, were 
put on the alfalfa plat from which the previous lot had been removed. 
It was soon apparent that these eight pigs would not keep the pasture 
fed down, and on July 20 four more, weighing a total of 139 pounds, 
were added. All 12 pigs were unable to keep the pasture fed down 
during "the early part of the period, so that it was necessary to clip 
the alfalfa once on each half of the plat. The 12 pigs were kept on 
this plat until September 10, when 6 were removed, the other 6 
remaining until September 30. During September, however, the pas- 
ture made but little growth and the 6 pigs gained only 59 pounds 
during the 20-day period. While on the alfalfa pasture, the hogs 
gained a total of 697 pounds from the quarter-acre plat of alfalfa 
and 1,267 pounds of corn, the latter being fed at the rate of approxi- 
mately 2.3 pounds daily for each 100 pounds of live weight. 
The results secured in 1913 with these two lots of hogs on alfalfa 
pasture are summarized in Table I, in which the data have been 
calculated to an acre basis.

A very important fact shown in Table I is the large number of 
hogs carried per acre of alfalfa pasture. From May 1 to July 2 the 
carrying capacity of an acre was at the rate of 20 hogs with an aver- 
age initial weight of 108.9 pounds, .and from July 20 to September 
10 the carrying capacity was at the rate of 48 hogs with an average 
initial weight of 39.8 pounds. The total final weight of the first lot- 
was 3,700 pounds, whereas the total initial weight of the second lot 
was only 1,900 pounds. This shows that the smaller the hogs the 
less total live weight the pasture will carry; that is to say, twenty 
25-pound pigs will require more pasture than an equal weight of 
100-pound shotes.
