Summary

The effects of the inclusion of raw and autoclaved faba beans (RFB and AFB respectively) and faba fractions (cotyledons and hulls) in diets for growing broiler chickens on performance, some digestive parameters and histological structure within gut mucosa were studied. Significantly decreased body weight was observed in those animals fed on diets containing 250 and 500 g/kg of RFB. Birds fed on AFB (500 g/Kg) or autoclaved faba bean cotyledons (AC)(426.4 g/Kg) in the diet showed significantly greater body weight than chicks fed on RFB or raw faba bean cotyledons (RC)(426.4 g/Kg). Dehulling of faba bean seeds produced no significant effect on this parameter, neither did the inclusion of raw faba bean hulls. Significant differences in duodenum, jejunum, ileum and caeca relative lengths, pancreas relative weight, intestinal transit time and plasma zinc concentration of the birds fed on RFB were observed. Birds fed on diets containing AFB or AC showed significantly decreased pancreas relative weight compared with RFB-fed birds. The inclusion of RFB hulls had no effect on these parameters. Dehulling and/or autoclaving of faba beans proved to have no significant effects on duodenum, jejunum, ileum and caeca relative lengths, neither had on plasma zinc concentration. The inclusion of RFB in the diets for growing chickens was shown to produce grave cytopathological changes within pancreas and small intestine mucosa. Birds fed on AFB and AC diets exhibited much more slightly altered intestinal structures as compared with RFB-fed chicks. The results indicate altered intestinal phy siology and structure in chicks fed on RFB or RC diets.
