this ratio varies considerably, depending on the ration used. It was 
shown that with com alone protein is stored at an average ratio of very 
nearly i to 7. Comparison of the amount of protein stored in the pig 
fed com alone and in the pig fed com and protein-free skim milk with 
the amount of protein consumed showed that the average ratio for these

two pigs was very nearly 1 to 7 for the whole period of the experiment. 
Since these two pigs were slaughtered, this comparison is direct. This 
means that these two pigs for the whole lifetime stored protein as effi¬ 
ciently as those younger pigs which were fed on com alone but grew 
more at an earlier stage. Since all these three pigs did not grow much
