| Abstract | ||||
| The effects of feeding on fresh or fried (12 or 24 hrs. ) cotton seed oil (eSO) and sunflower seed oil (SUN); pure or mixed with 5 or 15% rape seed (LEAR) oil were studied in rats. The results of the present work showed that there were on significant changes in the levels of serum triglycerides and total cholesterol of rats fed on the fresh unheated oils either pure or mixed. On the other hand. significant increases were seen in serum triglycerides by using eso mixed with 15% LEAR oil and in serum to\al cholesterol of SUN oil + 5% LEAR oil, while Significant decrease was observed in case of SUN oil mixed with 5% LEAR oil fried for 12 hrs. compared to the pure fresh unheated CSO. Concerning oil fried for 24 hrs .. there were marked slynifK:ant increases in serum triglycerides 'r1'/ feeding on pure eso and SUN oil or thai mixed 'tYith 5 and 15% LEAR oil and in serum total cholesterol in case of pure or mixed CSO with 5 and 15% LEAR oil. The enzyme activity of aspartate amino transferase (ASA T) in he serum did not change significanUy by feeding on unheated or fried oils either pure or mixed. On the other hand, serum alanine amino transferase (ALAT) activity showed significant increase in case of the unheated pure SUN oil. Pure SUN oil and lxed with 5% LEAR oil fried for 12 hI'S .. showed significant decrease, while significant ncrease was seen in case of pure SUN oil. fried for 24 hrs. Concerning the serum alkaline phosphatas activity (ALP). It was not affected significantly by feeding on he unheated fresh oils either pure or mixed except esa + 15% LEAR oU which Showed significant increase. While if was increased significantly in case of CSO mixed with 5% LEAR oil and the S UN oil either pure or mixed with 15% LEAR 011 fried for 12 hrs .. O~S (ried for 24 hI'S. . exhibited signifICant increase in serum ALP in case of pure eso and CSO + 5% LEAR oil. while signifiC<lnt decrease was observed in case of eso + 15% LEAR oil as well as in pure SUN oil. However, feed effIciency ratio revealed no signifICant increases in the rats fed on the fresh unheated oils except that fed on CSO mixed with 15% ~EAR oil and SUN oil mixed with 5% LEAR ojl which exhibited high feed efficiency ratio. Meanwhile. the feed efficiency ratios of oils fried for 12 or 24 hrs .. Whether pure or ixed did not change Significantly except CSO mixed with 5% LEAR oil which exhibited low feed efficiency ratio. The results also indicated a Significant increase in the weight f the liver of rats fed on unheated SUN oil pure or mixed with 5 or 15% LEAR oil. Co ceming oils fried for 12 hrs .. SUN oil mixed with 5 and 15% LEAR oU showed significant increase in the liver weight. However. significant increases were seen liver weight in case of eso + 5% LEAR oil and SUN oil + 15% LEAR oil after 24 hrs .. frying Meanwhile, there were no significant differences in the weight of the kidney in the different groups | ||||
