FURTHER NEBRASKA TESTS 



A number of extremely interestnig tests, of course not 

 decisive, have been made at the experimental substation, 

 at North Platte, under Supt. W. P. Snyder, to test the 

 economy and effect of alfalfa as hay and pasture as a 

 food for swine. The results of these tests have been 

 fully set forth in Nebraska Bulletin No. 99. 



Experiment No. i. — In the summer of 1904, from 

 July 16 to October 22, three lots of 17 pigs each 

 were run on alfalfa pasture and fed rations of corn. 

 All lots were quite uniform and of equal weights. 



Lot I was fed 3^ pound corn daily per 100 pounds of 

 weight of pigs. 



Lot 2 was fed i>2 pounds corn daily per 100 pounds 

 of weight of pigs. 



Lot 3 was fed 2>^ pounds corn daily per 100 pounds 

 of weight of pigs. 



The amount of feed was corrected to conform to the 

 weights at the end of each two weeks period. During 

 the 14 weeks of the experiment the average daily gain 

 of the pigs in Lot i was .28 pound; in Lot 2, .37 pound, 

 and in Lot 3, .51 pound, increasing as the percentage of 

 grain increased in the three lots. The amount of grain 

 required to produce 100 pounds gain was, by Lot i, 124 

 pounds ; by Lot 2, 222 pounds ; and by Lot 3, 332 pounds ; 

 showing that the lighter the grain ration, the less grain 

 was required for 100 pounds gain. The cost of 100 

 pounds gain was, in Lot i, $0.78; in Lot 2, $1.39; and
