The rapid determination of carcass fat by the Foss-Let specific gravity technique.
1. Carcass fat was determined by extraction with tetrachloroethylene and measurement of the solvent's change in density. The results were comparable in precision to those of a reference method; the new method extracted storage lipid but little structural lipid. 2. The technique is simple, rapid and appropriate for many nutritional studies.
