Table 9. The Effeet of Feed Form, Space Allotment, and Light Intensity Upon 

 Per Ont Mortality to 10 Weeks of Age. 



Intensity Average: 15 Foot Candles. 2.29: 120 Foot Candles.1.81 



Feed Form Average: Mash, 2.04; Pellets, 2.06 



Floor Space Average: 1 Sq. Ft., 2.15; % Sq. Ft., 1.94 



Eflfeet Upon Mortality 



Table 9 presents the effect of feed form, space allotment, and light in- 

 tensity upon percent mortality to ten weeks of age. The lowest mortality 

 percentage of 1.12 was in the 120 foot candles, pellets, and 1 square foot 

 group; the highest in the 15 foot candles, pellets, and 1 square foot group 

 with 3.06 percent. The analysis of variance of the combined three experi- 

 ments (Table II) indicates that none of the differences in mortality were 

 significant. 



Effect Upon Feather Score 



Average feather score resulting from the effect of feed form, space allot- 

 ment, and light intensity are shown for males in Table 10. The score for 

 males only are shown because in most cases the females did not show any 

 tendencv toward bare-backs. It should be remembered that a score of 1.0 

 indicates a completely feathered-back. The best average feather score of 

 1.03 was found in both the 15 and the 120 foot candles, mash, and 1 square 

 foot per bird groups. The two poorest were the 15 foot candles, pellets, % 

 square foot group and the 120 foot candles, pellets, % square foot group, 

 with scores of 1.62 and 1.84 respectively. 



The analysis of variance for the combined three experiments (Table II) 

 shows that ration had a highly significant, and space allotment a significant 

 effect on feather picking in males.
