The evaluated variables were daily feed intake, average egg weight, feed conversion (kg.kg-1 and kg.dz-1), eggshell percentage, yolk color and Haugh unit.
One hundred and sixty 25 weekold Lohmann laying hens were used in a completely randomized design with five treatments and four replications of eight birds per experimental unit.
Four periods of 28 days were evaluated during 112 days.
The inclusion of sunflower seed in the diet had no effect on production parameters during the experimental period.
Thus, can be concluded that sunflower seed might be used at concentrations up to 5.6% in laying hen diets without affecting performance and egg quality. 1 2 Universidade Estadual de Maringá.
