AbstractThe effects of different maternal dietary ω-3 fatty acids on hatchability and post-hatch development of the broiler chickens were investigated. Incubated eggs were Low (Lω3), Medium (Mω3) or High (Hω3) in ω-3 fatty acids. The eggs were produced by feeding broiler breeder hens with a wheat-soybean meal diet containing (g/kg) 50 g of sunflower oil (Lω3); 25 g sunflower oil + 25 g fish oil (Mω3); or 50 g fish oil (Hω3). Hens fed the Mω3 diet had highest (P<0.05) fertility and hatchability values 78.26 and 65.35% compared to 69.01 and 47.18% for the Hω3 fed group. However, hens fed the Lω3 diets produced eggs that were significantly (P<0.01) larger than eggs from the Mω3 and Hω3 fed group. Consequently, the day-old chick live-weight were significantly different (P<0.01) with chicks hatched from the Lω3 > Mω3 > Hω3 fed groups. Best performance was obtained from the Mω3 fed group, which might indicate an optimum level of ω-3 for hatchability and growth.
