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

It was postulated that a phytobiotic preparation containing cinnamon oil and citric acid added to drinking water for chickens in a suitable amount and for a suitable time would beneficially modify the microbiota composition and morphology of the small intestine, thereby improving immunity and growth performance without inducing metabolic disorders. The aim of the study was to establish the dosage and time of administration of such a phytobiotic that would have the most beneficial effect on the intestinal histology and microbiota, production results, and immune and metabolic status of broiler chickens. The experiment was carried out on 980 one-day-old male chickens until the age of 42 days. The chickens were assigned to seven experimental groups of 140 birds each (seven replications of 20 individuals each). The control group (G-C) did not receive the phytobiotic. Groups CT-0.05, CT-0.1, and CT-0.25 received the phytobiotic in their drinking water in the amount of 0.05, 0.1, and 0.2 mL/L, respectively, at days 1–42 of life (continuous application, CT). The birds in groups PT-0.05, PT-0.5, and PT-0.25 received the phytobiotic in the same amounts, but only at days 1–7, 15–21, and 29–35 of life (periodic application, PT). Selected antioxidant and biochemical parameters were determined in the blood of the chickens, as well as parameters of immune status and redox status. The morphology of the intestinal epithelium, composition of the microbiome, and production parameters of chickens receiving the phytobiotic in their drinking water were determined as well. The addition of a phytobiotic containing cinnamon oil and citric acid to the drinking water of broiler chickens at a suitable dosage and for a suitable time can beneficially modify the microbiome composition and morphometry of the small intestine (total number of fungi p < 0.001, total number of aerobic bacteria p < 0.001; and total number of coliform bacteria p < 0.001 was decreased) improving the immunity and growth performance of the chickens (there occurred a villi lengthening p = 0.002 and crypts deepening p = 0.003). Among the three tested dosages (0.05, 0.1, and 0.25 mL/L of water) of the preparation containing cinnamon oil, the dosage of 0.25 mL/L of water administered for 42 days proved to be most beneficial. Chickens receiving the phytobiotic in the amount of 0.25 mL/L had better growth performance, which was linked to the beneficial effect of the preparation on the microbiome of the small intestine, metabolism (the HDL level p = 0.017 was increased; and a decreased level of total cholesterol (TC) p = 0.018 and nonesterified fatty acids (NEFA) p = 0.007, LDL p = 0.041, as well as triacylglycerols (TAG) p = 0.014), and immune (the level of lysozyme p = 0.041 was increased, as well as the percentage of phagocytic cells p = 0.034, phagocytosis index p = 0.038, and Ig-A level p = 0.031) and antioxidant system (the level of LOOH p < 0.001, MDA p = 0.002, and the activity of Catalase (CAT) p < 0.001 were decreased, but the level of ferric reducing ability of plasma (FRAP) p = 0.029, glutathione p = 0.045 and vitamin C p = 0.021 were increased).

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.

Public Scrutiny

The subtherapeutic use of antibiotics in animals has been under scientific and public scrutiny as antibiotic growth promoters (AGP) have been linked to the development of antibiotic resistance in bacteria, which poses a threat to human health (Smith et al., 2003). Short chain fatty acids such as butyrate are considered as potential alternative to AGP, In addition to its bactericidal activity; butyrate appears to play a role in development of the intestinal epithelium (Leeson 2005). Prebiotics (e.g. mannanoligosaccharides, MOS) are nondigestible feed ingredients that can selectively stimulate growth or metabolic activity of a limited number of intestinal microorganisms (Gibson and Roberfroid, 1995). This study was, therefore, conducted to investigate effectiveness of mannanoligosaccharides and butyric acid as potential alternatives to AGP in broilers.

Corn Ddgs

This study was conducted to determine apparent ileal amino acids digestibility (AIAAD) of diets with different levels of corn distiller&rsquo;s dried grains with solubles (DDGS) and to determine AIAAD of corn DDGS by difference and regression methods in broiler chickens. One hundred and fifty 30-day-old male broiler chickens were used in the experiment. The corn DDGS were incorporated into basal diets at graded levels (0, 4, 8, 12, and 16%). All birds were killed at the age of 35 days and the contents of the lower half of the ileum were collected. AIAAD was calculated using chromic oxide as the indigestible marker. For AIAAD of DDGS determination, difference and regression methods were used. AIAAD of Lys (78.6%) and Met (91.3%) were the significantly highest in the diet without DDGS in comparison with other diets (P &lt; 0.01). AIAAD of the rest of essential and nonessential amino acids were the lowest in the diet with 8% of DDGS in comparison with the diets with 0 or 16% of DDGS (P &lt; 0.01). The apparent ileal crude protein digestibility was also the lowest in the diet with 8% (61.8%) of DDGS (P &lt; 0.01). The highest differences in AIAAD of DDGS determined by the difference method and in the diet without DDGS (basal diet) determined by the regression methods were found in Lys and Met. There were very low differences between DDGS and basal diet in AIAAD of nonessential amino acids, except Ala and Asp. These results show that higher levels of DDGS decrease AIAAD. &nbsp;
