Abstract: An experiment was carried out to evaluate the effect of 3%, 5%linseed oil in diets on the content of TG, TC, HDLC, LDLC in serum and activities of FAS in liver, LPL in abdominal fat and body fat deposition of broilers. Two hundred sixteen 21dayold Ross 308 female broilers were randomly divided into three treatments with each treatment replicated 6 times with 12 birds for replicate,which were fed control diets， 3% linseed oil and 5% linseed oil for 3 weeks. The results showed that serum levels of TG were not significantly different among treatments (P>0.05). The TC level was slightly higher than the control (P>0.05) and LDLC levels slightly lower than the control (P>0.05). The HDLC level in 3% LO was significantly higher than the control (P<0.05). FAS activity in liver and LPL activity in abdominal fat were lower in 3%, 5% linseed oil than the control (P>0.05) which is disagreement with the tendency of abdominal fat deposition.

Key words: broilers; linseed oil; fatty synthetase activity; fat deposition
