An experiment was conducted to investigate the effects of feeding graded levels of unprocessed and undehulled sunflower seed meal, on the performance of laying hens. One hundred and fifty Black Harco layers in their second month of egg production were randomly alloted to five diets in which sunflower seed meal (SSM) was tested at levels of 0, 2.5, 5.0, 7.5 and 10.0% of the diets for a ten week period. Average daily feed intake (ADFI), egg weights, egg shell thickness, yolk index and Haugh units did not show any significant (P>0.05) treatment effects. SSM significantly (P 0.05) affected by SSM. The effect of SSM on egg production would seem to recommend 7.5% as the optimum level inclusion.
