This study was conducted to determine the effect of different levels of omega-3 and omega-6 calcium fat powders on performance, hatchability, serum lipids, abdominal fat, and ovarian follicle count in Ross-308 broiler breeder hens (65 week-old). The experiment was performed in a repeated measurement design with 84 hens and 28 roosters with seven treatments (four replicates) during three months. The experimental groups included control group (no fat powder), 1.5 and 3% of animal omega-3 calcium fat powder of fish oil origin (?3F), plant omega-3 calcium fat powder of linseed oil origin (?3L), and omega-6 calcium fat powder of soybean oil origin (?6S). The results showed that the highest average of HDEP was belonged to the experimental groups containing 1.5% ?3F (61.98), and ?3L (60.25) without significant difference with together (P> 0.05). However, among experimental groups, the highest egg mass (44.78 g/h/d) was obtained from consumption of 1.5% ?3F (P<0.05). The highest concentrations of triglycerides (1806.8 mg/dL), cholesterol (206.25 mg/dL), and low density lipoprotein (244/25 mg/dL) of serum were belonged to control group that was significantly different from other experimental groups (P<0.05). The percentage of hatchability of fertile eggs was improved by consuming diets containing fat powder, except 3% ?6S, when compared to control (P<0.05). Overall, considering the production performance, hatchability and economic explanation of diets, it seems that addition of omega-3 calcium fat powder at the level of 1.5% (?3F and ?3L) is affordable and can have a positive effect on old broiler breeder hens.
