The Respiratory Quotient of Protein of the Dalmatian Dog¹

Nutrition Laboratory, Carnegie Institution of Washington, and Department of Biological Chemistry, Harvard Medical School, Boston, Massachusetts

The respiratory exchange of a Dalmatian dog was measured during fasting and after the ingestion of casein or meat in various amounts. The urine was collected by catheterization. The majority of the non-protein R. Q.'s were below 0.71, a fact that cannot be ascribed to formation of sugar from protein or to excretion of uric acid. As the urine showed no signs of acidosis, the protein R. Q.'s were calculated on the assumption that the fat metabolism was normal. They were all well below 0.81, and the hypothesis is advanced that the R. Q. of protein of the Dalmatian dog is lower than that used in general for protein.

The respiratory exchange measurements were made by Mr. Basil James and the urine analyses by Mr. Martin Stankard.
