Chromium-51 Determined Red Cell Volume as an Index of "Lean Body Mass" in Pigs1

H. Doornenbal2, S. A. Asdell and G. H. Wellington

Cornell University, Ithaca, N. Y.

Abstract

A correlation of 0.82 was obtained between the chemically determined protein mass of one-half of the dressed carcass and the Cr51-determined red-cell volume of the live animal prior to slaughter, using ten Berkshire pigs (5 males and 5 females) slaughtered in a weight range of 190 to 246 lb.

Application of this method to in vivo measurement of body lean has been discussed.
