The gain in weight was not very regular nor very great for 

 either lot, although for short periods some rapid gains were made. 

 Those birds (Lot A) having the animal meal ration gained in 

 weight during the trial about 20 per cent more than the others. 



During the first eight weeks the consumption of food by Lot A 

 was about 28 per cent greater than that of Lot B and the gain in 

 weight was about 40 per cent greater. One pound gain in weight 

 was made by Lot A for every 8 lbs. of water-free food consumed 

 and one pound gain by Lot B for every 8.8 lbs. of water-free food. 

 During the last four "weeks more food was still eaten by Lot A, 

 but the gain made was considerably in favor of Lot B as well as 

 the cost of the gain. The gain in weight for this period, however, 

 was not economically made by either lot. 



FEEDING TKIAL WITH DUCKLINGS. 



The feeding trial with the two lots of ducklings began as soon 

 as they had learned to eat and was continued until growth had 

 become very slow. The ration for Lot A, beside the grain mix- 

 ture No. described on page 48, consisted of corn meal, ground 

 oats and animal meal besides a little skim milk, curd and dried 

 blood. Lot B, besides the mixed grain No. 2, was fed wheat bran, 

 corn meal, ground oats and skim milk or milk curd. Both lots 

 were fed green alfalfa from the start. Sand and coarse grit were 

 freely supplied. The ration containing the animal meal had 

 generally somewhat the wider nutritive ratio and for the same 

 live weight fed supplied much less protein, although on account of 

 the much greater consumption of food the amount of protein per 

 fowl was considerably larger under this ration. 



The data follow in tabulated form, averaged in periods of one 

 week during the time of most rapid growth.
