with 3.365 pounds of feed required. Group 3. (19% meat scrap) was 

 least efficient, requiring 4.017 pounds. Combining the three groups 

 on each animal protein source we find the milk groups most effi- 

 cient, with 3.702 pounds of feed required to produce one pound of 

 gain. The fish, mixed protein and meat scrap groups follow in the 

 order named with 3.726 pounds, 3.791 pounds and 3.897 pounds, res- 

 pectively. The variations between groups are too small to be con- 

 sidered significant. 



Table 5 presents a summary of mortality records for all groups, 

 throughout the 23-week period. In no group was the mortality 

 greater than five per cent and in all the pens the major causes of 

 death were reported by the Poultry Pathology Laboratory as coc- 

 cidiosis, accident and gizzard erosion. 



GROWING PERIOD (13-23 WEEKS) 



Similar feed and management procedures were continued for the 

 13 to 23 week age period as during the initial twelve week period. 

 Referring again to Table 2, it will be noted that Group 12 leads all 

 others with an average weight of 4.825 pounds for females at 23 

 weeks of age. Group 4 was lowest in weight Avith 4.225 pounds 

 per bird, average. Combining groups according to type of animal 

 protein fed we find the mixed protein groups have maintained their 

 lead with an average weight at 23 weeks of 4.567 pounds per bird. 

 The milk, meat and fish groups follow in the order named. 



Very slight differences are noted in Table 3 recording the total 

 feed consumed during this period. Table 4 shows the 15 per cent 

 dried skimmilk group to b'e most efficient in the utilizaton of feed 

 with 8.382 pounds required per pound of gain. The least efficient was 

 Group 6 (19% fish meal) with 11.120 pounds of feed required. 



Birds that received meat scrap were most efficient in feed utiliza- 

 tion with a requirement of 8.891 pounds of feed. The milk, mixed
