also carbohydrates) to a protein diet makes the consumption of 

 protein smaller than it would be without this addition. The fat 

 as well as the carbohydrates preserve the protein from decomposi- 

 tion, thereby favoring the formation of new body tissue. 



The following experiments with a dog by Voit also illustrate 

 this, which is also proved by many others: 1

69. Teachings of the above in feeding practice. From what we 

 have learned we should expect the best results when the ration 

 fed contains a sufficient supply of protein with a large proportion 

 of carbohydrates to protein,*, e., a wide nutritive ratio (132), 

 and this we find borne out by the results of numerous experi- 

 ments with all kinds of animals. We quote the following experi- 

 ments on sheep by Schulze and Marcker, arranged by Armsby 

 according to the nutritive ratios in the different rations. The 

 protein in the wool, amounting to about five grams, is not 

 included in the figures for protein consumption. 2
