The effect of diet linoleic acid level on egg weight, egg composition, hatchability, chick weight, yolk sac percentage relative to chick weight and yolk fatty acid composition of broiler breeders Ross 305, from 27 to 40 weeks of age, were evaluated using two diets with two levels of linoleic acid. Egg weight and linoleic acid yolk composition were higher for diet with 1.93% of linoleic acid than for diet with 1.48% (59.5g vs 59.0g and 19.5% vs 15.5%, respectively). No linoleic acid effects on yolk, albumen, egg shell, yolk sac percentage and hatchability and chick weight were observed.
