from 1,602 to 4,554 pounds per acre, and the grain fed for each 100 
Soutids of gain ranged from 170 to 321 pounds. These data will be 
further discussed later. 
Haperiments at the Huntley Experiment Farm.—tvThe results ob- 
tained with pigs on alfalfa pasture at Huntley from 1913 to 1916, in- 
clusive, are summarized in Table V. There were in all 7 lots. Each 
lot had access to one-quarter of an acre of alfalfa and was fed a 2 per 
cent supplementary ration of corn. The same general methods were 
followed as for Scottsbluff, already described. 
TABLE V.—Results secured with seven lots of pigs on irrigated alfalfa pasture

The 7 lots used at Huntley contained a total of 37 spring-farrowed 
pigs in 4 lots and 14 fall-farrowed pigs in 3 lots. ‘The gains per 
acre of alfalfa ranged from 14 to 25 pounds per day; the average 
carrying capacity varied from 1,818 to 3,784 pounds per acre, and 
the grain fed per 100 pounds of gain ranged from 197 to 414 pounds. 
Euperiments at the Belle Fourche Experiment Farm.—tThe results 
secured with 10 lots of pigs are available from Belle Fourche. Each 
lot had access to one-fourth of an acre of alfalfa and received:a 2 
per cent supplementary ration of corn. Each pasture was divided 
into two equal parts, which were grazed alternately, as at Scottsbluff 
and Huntley, and the methods used were essentially the same as those 
employed at the other two stations. The results are summarized in 
Table VI. 
At Belle Fourche were 6 lots of spring-farrowed pigs, a total of 
43, and 4 lots of fall-farrowed pigs, a total of 16, or 59 in the 10 lots. 
The gains per acre of alfalfa varied from 12 to 19 pounds per day,
