Abstract
This study was conducted in poultry farm of College of Agriculture, Al-Anbar University. The objective of this study was to determine the possibility of using partial replacement of (Vicia faba L.) instead of Soybean meal on egg quality during summer months. Five levels of (Vicia faba L.) were used (0, 2.5, 7.5, 12.5 and 17.5)%, so five treatments were obtained with 5 replicates for each Seventy five ISA Brown layers aged 30 weeks were used. This study lasted for three periods (July-September). The duration of each period was (28 days). The results indicated significant increase in egg quality when feeding hens an theist included 2.5-7.5% (Vicia faba L.) during the summer month. However, significant reduced in Yolk index, specific gravity and shell thickness at August as compare with July and September. The results of this study also revealed, no significant differences among different treatments in shape index, Yolk index and Haugh Unit. There's no significant differences between experimental months in shape index and Haugh Unit.
