the heaviest in the experiment, but from that time flock 59 ( powdered 

 milk mash) was of greatest weight. 



The very small increase in total weight in flocks 55. 56, 57 and 58 during 

 the fourth and fifth weeks was due in some degree to the high mortality. 



Weight of flock at 6 weeks : 



Greatest — Flock 59 — Wet mash, powdered milk ration — 57.49 lbs. 

 Least — Flock 56 — Cracked grain ration 31-92 lbs. 



Average weight of chicks 



Flocks 55 (cracked grain, bran) and 59 (powdered milk mash) were 

 slightly heaviest in average weight of chicks at the beginning of the ex- 

 periment. During the first week the chicks in flock 60 (skimmed milk 

 mash) became heaviest and remained so till the fourth week. Then flock

59 took the lead and kept it to the end of the six weeks. It will be seen 

 from Table 5 that the average weight per chick in flocks 55, 56, 57 and 

 58 was largely increased during the sixth week. This was due to the 

 culling out of a number of the smaller chicks rather than to a larger 

 increase in weight of the remaining chicks. The average weight of 

 chicks was much less in the flocks having the dry-grain rations (55 to 58) 

 than in those having the wet-mash (59, 60) and the variety rations (61). 

 For a comparison of the gain in weight, see Figs. 172 and 173. 

 Average weight of chicks: (Table 5.) 



Greatest — Flock 59 — Wet mash, powdered milk ration — 0.542 lbs. 



Least — Flock 57 — Cracked grain, dry-mash ration — 0.343 lbs.
