The aim of this study was to investigate the effects of feeding dietary protected linseed (LIN), fish oil (FO) and a 50:50 mix of the two sources (LINFO) on lipid composition of kidney tissue. Twelve rams were housed individually and received similar fat levels (50g/kg/DM) from different fat sources. The rams were fed a basal diet of a 70:30 mixture of haylage and concentrate. The rams were randomly allocated to each of three protected fatty acid (FA) sources; LIN, FO and LINFO. After 12 weeks, rams were fasted for 18 hours and taken to the abattoir. Kidney tissue samples were collected for fatty acid analysis. The concentration of C18:3 n-3 in the kidney of rams offered diet containing LIN was significantly greater (P=0.002) than those observed in rams given the FO and LINFO diets. The concentration of C20:5 n-3 and C22:6 n-3 in the kidney of rams offered diets containing FO and LINFO diets were significantly increased (p 0.001) than rams receiving the LIN diet. In conclusion, dietary LIN, FO and LINFO altered the fatty acid composition of lipids of kidney tissue of rams.
