KEYWORDS
ABSTRACT
Ruminant tissues and products contain conjugated linoleic acids (CLA) due to biohydrogenation
in the rumen. We hypothesize that kangaroos would have higher concentrations of CLA compared
to lambs due to incomplete biohydrogenation of fatty acids in the kangaroo foregut. Fatty acid
composition of adipose tissue (including cis 9, trans 11 CLA) from lambs and kangaroos were
significantly different. The concentrations of CLA and its precursor trans vaccenic acid (TVA) in
the adipose tissue of kangaroos were approximately four and five times that of lambs. Kangaroo fat
was significantly less saturated and had a lower melting point.
