lower ND, respectively. Proventriculus and heart weights were significantly decreased by dietary treatments too. Ileal viscosity was significantly (P<0.028) affected by ND while the viscosity in feed was significantly (P<0.035) effected by OA supplementation. Villi height was significantly (P<0.015) increased by OA supplementation both in the standart or lower ND groups. This effect was better pronounced in lower ND fed group and the rate of the increase was 20%. In the case of villi depth interaction effect was observed, while significant drop in the group fed with standart ND, only slight increase was seen in the group fed with lower ND. Organic acid supplementation consistently decreased crypt depth (from 120.1 to 113.1 and from 117.3 to 96.3 μm) irrespective of ND. No significant effect could be observed by dietary treatments with respect to thickness of ileal muscle layer.
