This research studied the fatty acid profiles of jojoba oil and treated jojoba oil by using gas chromatography, its effect as a growth promoter on body weight, protein profile, and some biochemical parameters in Turkey. 15 healthy unvaccinated white male turkeys were divided into three groups, group 1 (control), group 2, and group 3 were continuously given treated jojoba oil in a concentration of 2.5% and 5% of the ration weight, respectively, for 90 consecutive days. The GC analysis showed that JO and TJO consist of 22 and 27 fatty acids, respectively. Also, our results illustrated a significant increase in body weight gain with a better feed conversion ratio, a significant increase in total protein and globulin levels, an elevation in superoxide dismutase and reduced glutathione levels, and a significant reduction in the amount of the consumed ration in groups 2, and 3 in comparison with group 1. No significant differences were observed between groups in AST, ALT, urea, or creatinine levels. In conclusion, TJO in a concentration of 2.5 and 5% provides a significant effect on body weight gain, feed conversion ratio, serum antioxidant capacity, and enhancing immunity but we recommend the usage of TJO in a concentration of 2.5% from an economic point of view.
