DISPOSAL OF IRRIGATED CROPS THROUGH THE USE OF HOGS. 23 



plats in 1915 had also been badly damaged by hail. As the results 

 from the 1914 experiment were almost identical with those of the 

 1915 experiment, only the 2-year average will be discussed here. 



Com alone. — The corn hogged by the four lots receiving no sup- 

 plementary feed was estimated as the equivalent of 1,091 pounds of 

 shelled corn, and the equivalent of 209 pounds of shelled corn was 

 added, making a total of 1,300 pounds of corn consumed. These lots 

 made an average gain of 248 pounds. For each 100 pounds of gain 

 they consumed 524 pounds of corn, valued at $5.61. 



Com plus alfalfa pasture. — At the time of year when corn is 

 hogged alfalfa makes slow growth. Before the experiment closed, 

 the alfalfa was furnishing but little feed. The hogs receiving 

 alfalfa as a supplementary ration had access to about the same area 

 of alfalfa pasture as was occupied by the corn plat. They were 

 charged at the rate of $1 an acre for the use of the alfalfa pasture 

 after the last cutting. The lots made a total gain of 310 pounds. 

 It was estimated that they hogged 1,163 pounds, and 220 pounds 

 were added to the plat, making an equivalent of 1,383 pounds of 

 shelled corn consumed. It required 446 pounds of corn, supple- 

 mented by alfalfa pasture, to make 100 pounds of gain, which 

 cost $4.88. 



Com and tankage. — The lot on corn and tankage made 343 pounds 

 of gain. It was estimated that the corn plat yielded 1,038 pounds, 

 and 349 pounds of corn were added, making a total of 1,387 pounds 

 consumed. In addition to the corn, the lot was fed 100 pounds of 

 tankage. The tankage cost $3.20 per hundredweight, delivered at 

 Mitchell, Nebr., in 500-pound lots. For each 100 pounds of gain 

 made, the hogs ate 405 pounds of corn and 29 pounds of tankage. 

 The gains cost $5.26 per 100 pounds. 



A summary of the two years' results of these experiments, calcu- 

 lated to an acre basis, is given in Table IX.
