The experiment was conducted over 12 weeks period with one hundred and sixty 24 weeks old white leghorn hens. Diets containing 0, 10, 20 and 30% acorn seeds of Quercus branti were given to caged laying hens in first phase of egg production (weeks 24-36). Egg weight, feed intake, mortality rate and body weight were not significantly affected by the treatments, but egg production rate, egg number, egg mass by P<0.01 and feed efficiency with P<0.05 were affected by the experimental diets. It could be concluded that treatment containing 30% acorn seeds significantly reduced egg production rate, egg number, egg mass, and feed efficiency in first phase of egg production (weeks 24-36). But acorn seeds could be used in the diet of laying hens in place of corn up to 20% with no serious adverse effects onperformance.
