The current study investigated the effects of the inclusion of modern hybrid rye (Brasetto variety) to a corn–wheat-based diet, with or without xylanase, on the absorptive surface of the small intestine of broilers. A total of 224 one-day-old male Ross 308 broiler chicks were randomly divided into four experimental groups with seven replicate cages of eight birds/replicate. A 2 × 2 factorial study design was used, with rye inclusion (0% or 20%) and xylanase supplementation (0 or 200 mg/kg of feed) as factors. Inclusion of rye increased duodenal and ileal crypt depth, villi height, the villus-to-crypt ratio and absorption surface area (p < 0.05), and ileal mucosa thickness and crypt width (p < 0.05). Xylanase supplementation attenuated the effects of rye in the duodenum and ileum and decreased the villi height and villus-to-crypt ratio in the jejunum (p < 0.05). Rye and xylanase had no effect on the spatial distribution of claudin 3 and ZO-1 protein, but xylanase supplementation reduced the amount of claudin 3 in the duodenum and jejunum (p < 0.05). The findings of this study indicate that 20% inclusion of modern hybrid rye to the diets of broilers improved the structure of the duodenum and ileum, but these effects were attenuated by xylanase supplementation.

The aim of this study was to investigate the effects of methionine (Met) deficiency on antioxidant functions (in the duodenal, jejunal and ileal mucosa) and apoptosis in the duodenum, jejunum and ileum of broiler chickens. A total of 120 one-day-old Cobb broilers were divided into two groups and fed a Metdeficient diet and a control diet, respectively, for six weeks. The activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px), the ability to inhibit hydroxyl radicals, and glutathione (GSH) content were significantly decreased in the Met-deficient group compared to the control. In contrast, malondialdehyde (MDA) content was significantly higher in the Met-deficient group. As measured by terminal deoxynucleotidyl transferase 2’-deoxyuridine 5’- triphosphate dUTP nick end-labelling (TUNEL) and flow cytometry (FCM), the percentages of apoptotic cells were significantly increased. In conclusion, dietary Met deficiency can cause oxidative stress and then induce increased apoptosis in the intestine. Oxidative stress contributes to intestinal apoptosis. This results in the impairment of local intestinal mucosal immunity due to oxidative stress and apoptosis in the small intestine. The results of this study provide new experimental evidence for understanding the negative effects of Met deficiency on mucosal immunity or the functions of other immune tissues.
