This study was conducted to investigate the effects of two types of omega-3 calcium fat powders with animal and vegetable origin on productive performance, reproductive and egg quality of broiler breeder hens by using 60 hens and 20 roosters (65 weeks), in a completely randomized design with five treatments and four replicates for two months. Experimental treatments were: 1- control (without fat powder); 2- 1.5% animal omega-3 calcium fat powder based on fish oil; 3- 3% animal omega-3 calcium fat powder based on fish oil; 4- 1.5% vegetable omega-3 calcium fat powder based on flaxseed oil; 5- 3% vegetable omega-3 calcium fat powder based on flaxseed oil. Egg production percentage and economic benefit of hens fed with diets containing 1.5% animal and vegetable fat powders were greater than hens that received 3% of them (p<0.05). The highest concentration of yolk docosahexaenoic acid and docosahepanthanoic acid were in eggs of hens fed with diet containing 3% animal and vegetable fat powder and thelowest concentration of linolenic acid was in the yolk of eggs obtained from control hens or hens fed with diet containing 1.5% animal fat powder (P<0.05). The lowest percentage of hatchability and the highest omega-6: omega-3 ratio were related to hens received control diet (P<0.05). Based on current results, adding animal or vegetable omega-3 calcium fat powder at the level of 1.5% in old broiler breeder hen’s diet, without negative effect on performance, improve hatchability and yolk fatty acid composition and is economically more affordable.
