Abstract
A trail of feeding broiler breeders crude and treated Vicia sativa at a rate of 11% and 22%, was conducted to elucidate the effect of using this seed on the egg's IgY content and on the relative weight of the ovarian follicles. Results revealed that crude seeds were effective in significant reduction of IgY content and of the ovarian weight. Treating crude seeds at the low level (11%) with water, acetic acid, Saccharomyces cereviceae, and activated charcoal were effective in ameliorating the negative effects of antinutritional factors in crude V. sativa and transfer more immunoglobulin IgY through eggs comparing with control group. Treatment of crude seed at a high level (22%) was different in their effect on IgY content and the relative ovarian follicle weight. This study reveals and for the first time, that different treatments of crude V. sativa could enhance the maternal immunity transferred via IgY through eggs to offspring in order to improve the transferred maternal immunity to the hatched chicks and to sustain a high immunological profile against different infectious diseases.
