Effect of dietary polyunsaturated fatty acids on productive performance of broiler chicks

Abstract: Three hundred and fifty two one-day-old Arbor Acres broiler chicks were used. The chicks were divided into 11 treatments to evaluate the effects of dietary polyunsaturated fatty acids on some productive performance of broiler chicks, each in four replicates, each replicate included eight chicks. The experiment was extended up to six weeks of age. No vaccination or any ant microbial agents or prevention program was applied in this study. The basal experimental diets contained 23.07% and 20.02% crude protein : and 2926.6 and3074.8 kcal ME/kg diet of the starter and the starter and the grower diet, respectively. Three sources of oils of were used, being linseed oil, maze oil and sunflower oil. The eleven treatments were aimed to study the effects of each oil alone in treatments ( No. 2,3,4 respectively) and the possible combinations among the three oils in treatments (No.5,6,7,8,9,10 and 11). While chicks in treatment No. 1 were served (without any adding of oil) as control. The oil was replaced by 3% of the basal diet ( in all treatments from 2- 11). All diets within each feeding period were formulated to be nearly isonitrogenous and calorie/protein ratio was kept as constant as possible.
Obtained results indicated that dietary oil increased significantly the body weights at 3 and 6 weeks of age. Sunflower oil recorded the highest body weight either when used alone or with any other combinations. Dietary oil did not affect feed intake. Dietary oil improved significantly feed conversion, the best- feed conversion values were obtained when sunflower oil combined with linseed oil. Abdominal fat percentages were significantly increased by oil supplementation. The highest values were obtained for birds receved sunflower in combination with linseed oil. Blood serum calcium concentrations showed a notified decline by oil supplementation.
