Flock 61 (variety ration) ate less per pound weight than any other 

 flock in the experiment (Fig. 174). Flocks having the wet mash ate less 

 per pound weight than those having dry mash, and cracked grain and 

 dry mash. The flocks having the cracked grain, and the cracked grain 

 and bran, ate less than the flocks having the dry mash, and the cracked 

 grain and dry mash. In other words, the variety ration reared chicks 

 to six weeks on least food consumption per pound weight; wet-mash 

 rations were next, cracked-grain rations third, while the flock having 

 only the dry mash required most food of all. 



Dry matter consumed per poimd weight : 



Greatest — Flock 58 — Dry mash ration — 4.50 lbs. 

 Least — Flock 61 — Variety ration — 2.76 lbs. 



Cost per pound live weight of chicks 



Table 7. — Cost op Food and Labor per Pound Live Weight for Each Week 



AND for Six Weeks 



For the six weeks of feeding, the wet-mash rations supplied the 

 chicks at a cost of 21 per cent, less per pound weight than did the 

 cracked-grain rations, and at 43 per cent less cost than the rations 

 consisting altogether or in part of dry mash. When speaking of the 

 rations having part dry mash, no reference is intended to the variety 

 ration, although this ration does contain a proportion of dry ground 

 food. The powdered milk mash cost two per cent less per pound 

 weight of chicks than the variety ration, and six per cent less than 

 the skimmed milk mash. The great cost of the variety ration came 



* In compiling the tables of "per pound weight," the figures for each week were found by dividing 

 the total amount of dry matter, or cost of food and labor, as the case might be, for the week, by the 

 total weight of the chicks remaining at the end of the week. The summary for six weeks was found 

 by dividing the total amount of dry matter in food, or cost of food and labor for the six weeks, by 

 the weight of chicks remaining at the end of the six weeks period. For this reason the summary 

 for six weeks does not check with the totals of the weekly periods. 



In the tables showing the "per pound gain," the figures were found by dividing the amount of dry 

 matter in the food, or the cost of food and labor, by the total pounds excess in weight at the end of 

 each week over the weight of the preceding week, instead of by the total weight. The gain in weight 

 for six weeks was found by subtracting the weight of the flocks at the beginning of the first week 

 from their weight at the end of the sixth week. This method of calculation was used with both th« 

 feeding and the fattening experiments.
