Adding wheat and rapeseed meal to corn-soy diets affects intestinal morphology and nutrient digestibility in broilers

This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) protein resources (soy rapeseed meals) gut morphology digestibility broiler chickens. Three hundred eighty-four male Ross-308 chickens were used a 23 factorial arrangement treatments according completely randomized design. The morphological examinations intestine carried out 1-cm long excised segments from duodenum, jejunum ileum. Adding wheat diet increased small length in birds compared other feedstuffs (P <0.05). Duodenum crypt depth villi also higher groups fed containing Groups that received had duodenum However, two- three-factor interaction not significant. Protein affected by treatment >0.05). Feeding may increase surface area for nutrient absorption as compensation anti-nutritive activity non-starch polysaccharides wheat-based diets. Wheat based diets are expected be acceptable broilers when supplemented appropriate enzymes oil.
