dc.description.abstractThis research has been carried out in order to analyze the effects of the composition of fatty acids in animal products, growth and egg productivity when hazelnut and sunflower oil used in layer hens and broiler diets. The first trial was performed with layer hens consisting of 5 trial groups in which one of them was selected as a controlled group (without oil). For the remaining four groups, the following oil percentages were given during the trial; 1.5% sunflower oil (S.O.). 1.5% hazelnut oil (H.O.). 3% H.O. and 3% mixed oil (M.O) (1.5% S.O. + 1.5% H.O.) respectively. This trial lasted for 135 days. The second trial was carried out with broiler chickens for four trial groups. 2.5% S.O. (control group). 2.5% H.O. 5% M.O. (2.5% H.O. + 2.5% S.O.) and finally 5% H.O. This trial continued for 40 days. At the first trial, it was observed that use of H.O. results while reducing both feed consumption (FC), feed conversion ratio (FCR), damaged eggs and body weight gain, number of healthy & sellable eggs increased. The yolk color of the group fed with S.O. was found to be low. The percentage of unsaturated fatty acids in rations into which oil had been added was found to be higher as compared to the control group. The use of 3% H.O. or mixed oil resulted in remarkably increasing unsaturated fatty acid (UFA) proportion in eggs when compared to the control group. At the same time amount of oleic acid in the yolk was found to be higher as compared to the groups fed by H.O. In the second trial, control group was observed to have minimum gain in the weight and the addition of hazelnut oil directly correlated with positive weight increases. Ration fatty acids composition also proportionally influenced the oleic and linoleic acids in the tissues. As a conclusion, oils that are rich for the aspect of oleic acids used in the rations of the poultries should be preferred for both having high energy levels and positive effects on weight growth and egg productivity.en_US
