Abstract
1. Three trials were conducted to study the influence of diets containing between 40 and 550 g broad bean (Vicia faba, Major) meal/kg on performance, egg quality and pancreas characteristics of White Leghorn hens.
2. The effect of broad beans on performance depended on the dietary content. Up to 100 g/kg did not affect productivity. Contents higher than 200 g/kg depressed egg weight (P<0.05). At 550 g/kg, food intake, egg weight and rate of egg production decreased but efficiency of food conversion was not impaired.
3. At 550 g/kg broad beans caused an increase in albumen density (P < 0.01). Broad beans did not affect shell thickness.
4. The size, weight, moisture content and histology of the pancreas were not affected by broad bean intake.
