of 51 pounds, the two lots of ewes consuming- the same kind and 

 practically the same amount of feed. The lambs in Lot 1, fed corn 

 alone made practically the same average daily gain as did those in 

 Lot 2, fed the grain mixture of corn, oats, bran and oilmeal. 



TABLE VIII. EXPERIMENT III. Weekly weights and gains, and total gains 



1 Four ewes and lambs were removed from each lot, February 12. 



2 Five ewes and 4 lambs, removed from Lot 1, and 4 ewes and lambs removed from Lot 2, Feb. 19. 



3 One lamb, weight 34 pounds, died February 22, and 1 lamb, weight 12 pounds, died February 26. 

 The dams of these 2 lambs, weight 180 pounds, were removed February 26. 



4 One lamb, weight 35 pounds, died March 20. 

 * See note under Table V, page 207. 



COST OF GAINS 



Table IX shows the amount and cost of feed fed per pound of gain 

 made by the lambs with feed at the prices indicated in the table. 

 In calculating the cost of gain made by the lambs, the value of the 

 gain or loss made by the ewes was valued at 3% cents per pound. 

 When this allowance is made, Table IX shows that the lambs in Lot 

 1 made slightly more expensive gains than did the lambs in Lot 2. 

 If no allowance is made for the gain or loss made by the ewes, the 

 lambs in Lot 1 made slightly cheaper gains than did those in Lot 2. 

 In neither case is the difference great enough to indicate any strik- 

 ing difference in economy between the two rations. The cost of the 

 grain fed to the lambs constitutes such a small percentage of the 

 total cost of feed consumed by both ewes and lambs that it has but 

 little influence on the cost per pound of gain made by the lambs.
