the higher percentage of egg production in pen 13 (weak) over pen 11 

 (strong). In all other comparison flocks, as well as in the averages of 

 all the strong and weak flocks, the strong flocks consumed more meat 

 scrap and produced more eggs than did the weak flocks. This higher 

 production in the pens consuming the greater proportion of meat scrap 

 to grain is true in all three parts of these experiments. The ratio of 

 protein to carbohydrates and fat varied in the same proportion and in 

 the same pens according to the consumption of mash and meat scrap and 

 the production of eggs. When the ratio was narrowest, the egg production 

 was greatest. The average ratio for the best production was about i :4.5.
