Cost of Oil and Food. 



The oil required by each brooder during the ten weeks that 



they were heated amounted to 4^ gallons. Considering only the 



cost of oil and food, the cost of the gain in weight made by Lot 



No. I during the three months would be 3.98 cents per pound. 



The cost of the gain made by Lot No. II would be 4.5 cents per 



pound. 



Relation of Food to Growth. 



The food eaten during the three months by Lot No. I, having 



the ground grain ration, contained 31.2 pounds more dry matter 



than that eaten by Lot No. II and the gain in weight was 8.9 



pounds greater. For every pound gain in weight made by Lot 



No. I there were 4.56 pounds of dry matter in the food consumed. 



For every pound gain in weight made by Lot No. II there were 



4.4 pounds of dry matter in the food. 



Cost of Food for Growth. 



By Lot No. I one pound gain in weight was made for every 3.33 

 cents worth of food consumed. By Lot No. II one pound gain was 

 made for every 3.76 cents worth of food. 



At the average weight of one pound the food had cost per 



chick for Lot No. I, 3 cents and for Lot No. II, 3.7 cents. At the. 



average weight of 1.5 pounds the food h«d cost per chick 4.9

The chicks in Lot No. I averaged one pound in weight at six

No. I at ten weeks of age the average weight was 2 pounds and 



in Lot No. II, 1.8 pounds. 



Cost of Production. 



Rating the cost of hatching (including the cost of eggs, etc.) 



at the average cost found in former experiments, and considering 



the cost of food and of oil for brooders, gives as the total cost per
