| Abstract | Diets containing cyclopropenoid fatty acids (CPFA) were fed to rainbow trout. At a level of 223 ppm (from Sterculia foetida oil), these CPFA in six weeks reduced weight gain by as much as 50 percent over the control fish on the same diet without CPFA. Compounds containing the intact cyclopropene ring were recovered from the tissue lipids of the trout at approximately two-thirds of the level fed. These acids seemed to concentrate in the egg lipids of the adult female fish. At 223 and 2233 ppm (from S. foetida oil) and 50 ppm (from food grade cottonseed flour) the CPFA were demonstrated to alter lipid metabolism. In general, the CPFA fed fish had higher stearic and palmitic acid levels and lower oleic and palmitoleic acid levels in their tissue lipids than did the controls. On diets containing corn oil or corn oil plus salmon oil, fish fed CPFA tended to deposit more long chain unsaturated fatty acids than did their controls. When provided with tristearin as the sole dietary lipid, the CPFA fed fish reduced the level of unsaturation of their tissue lipids. |
