experiments. One is to charge the pigs with only the feed and the 

 other is to charge the pigs with both feed and the loss in weight of 

 the sows. The second method is used here. 



In 1914 two sows and 14 pigs were put on the alfalfa pasture plat 

 on May 4. On this date the two sows weighed a total of 702 pounds 

 and the 14 pigs a total of 164 pounds. The experiment closed on July 

 3. At this date one sow still remained on the plat, while the other one 

 had been taken off on June 19. The final weight of the two sows was 

 G03 pounds, or 99 pounds less than the initial weight. The 14 pigs 

 weighed a total of 636 pounds. They had increased in weight 472 

 pounds in 60 days. The total initial weight of the sows and pigs 

 was 866 and their total final weight 1,239 pounds, or a total increase 

 of 373 pounds for the lot. The lot was fed 1,176 pounds of corn. 

 The 373 pounds gain at $7 per hundredweight is worth $26.11. De- 

 ducting from this the cost of 1,176 pounds of corn at $1.07 per hun- 

 dredweight, or $12.58, leaves a return of $13.53 for one-fourth acre 

 of alfalfa pasture for 60 days, or a daily return of 90 cents per acre. 

 The sows and pigs ate 3.02 pounds of corn for each pound of net 

 gain. With corn at $1.07 per hundredweight and alfalfa pasture 

 at $7 an acre for 60 days, 100 pounds of gain cost $3.83. This lot 

 paid the equivalent of $19.02 a ton for alfalfa hay. A tabulated 

 statement of this lot is given in the first column of Tables VI 

 and VII. 



In the 1915 tests, which began April 27 and ended June 26, there 

 were three lots of two sows and litters each. One lot was fed ground 

 barley and the other two lots were fed corn. They were fed grain 

 at the rate of about 2 pounds daily for each 100 pounds of live 

 weight. In two of the lots old sows were used and in the other gilts 

 were used. The total initial weight of lot 6, which received ground 

 barley, was 760 pounds. The sows weighed 702 and the 17 pigs 

 58 pounds. One sow was taken off on June 9. The other remained 

 until the close of the experiment. The total final weight was 1,178 

 pounds, or a total gain of 418 pounds. The sows lost 28 pounds 

 and the pigs gained 446 pounds. A total of 982 pounds of ground 

 barley was fed to this lot. From each 100 pounds of grain fed 

 this lot produced 42.5 pounds of gain. After paying $1 per hun- 

 dredweight for the barley fed, the lot still paid at the rate of $1.30 

 daily for an acre of alfalfa pasture. In lot 7, which was fed corn, 

 the initial weight of the two sows was 873 pounds and of the 

 15 pigs 83 pounds, or a total of 956 pounds. The old sows were 

 taken off the plat on June 9. At this date they weighed 780 pounds, 

 or 93 pounds less than they did when the experiment began. The 

 final weight of the pigs was 574 pounds, their increase being 491 

 pounds. The total increase in weight of the lot was 398 pounds.
