Cost of Producing 100 Pounds Gain in Live Weight. — The 
experiment began December 21. The two lots of 10 lambs 
each were very nearly of a size, the total weight of the lambs 
of Lot 1 being 13 pounds more than that of Lot 2. When the 
experiment began, Lot 1 weighed 882 pounds. On January 
21 the weight was 987 pounds, making a gain in 31 days of 105 
pounds, or an average of 10} pounds for each lamb. During 
the 31 days of the second period the gain in weight was 137 
pounds, or 13.7 pounds per lamb. : 
Lot 2 on December 21 weighed 869 pounds, while on Jan- 
uary 21 this lot weighed 1,034 pounds, making a gain of 165 
pounds in 31 days, or 164 pounds per lamb. On February 21 
the weight of this lot of lambs was 1,150 pounds, giving a gain 
of 116 pounds in 31 days, or 11.6 pounds per lamb during the } 
second period. It will be seen that the gains for the second 
lot, which were fed the wide rations, are considerably larger 
than for the first lot, which had the narrow ration. 
The wide ration (Lot 2) was somewhat more expensive than 
the narrow ration (Lot 1), but the average cost of 100 pounds 
of increase was 16 cents less for the lambs fed the wide ration. 
The following table shows the gains for each period, the daily 
cost of the rations, and the cost of 100 pounds of increase in 
live weight: gi an
