Constitutional Vigor in Poultry 



591 



Owing to the change in relative proportion of the consumption of 

 whole grain and dry mash (containing the meat scrap), the ratio of 

 protein to carbohydrates was narrower during the second year of feeding. 

 (Table 13.) This may partially account for the fact that the produc- 

 tion of eggs per pound of dry matter consumed remained as low for 

 the yearling fowls as for the pullets.

 (December 8, 1908, to December 6, 1909) 



The amount of dry matter consumed per pound live weight was several 

 pounds less during the second year of feeding than during the first. 

 (Table 14.) Eggs were produced, also, at practically the same expenditure 

 of dry matter as during the preceding year. Although the same number 

 of eggs was produced the second year, for each one hundred pounds 

 of dry matter consumed a smaller total munber of eggs was produced.
