An experiment was conducted to determine the effect of injecting glucagon-like peptide 2 (GLP-2) on the small intestinal weight, morphology, and nutrient transporter expression in pharmacologically stressed broiler chickens. A total of 144 seven-day-old birds were fed either a basal diet (CTRL) or a basal diet plus 30 mg of corticosterone (CORT)/kg of diet for a total of 14 d. Half of the birds...

The aim of this study was to investigate the effect of commercial herbal and chemical medicines on growth performance, serum lipids, intestinal selected bacterial population and intestinal morphology of broiler chickens. In this study, 450 day-old female broiler chickens (Arian strain) were divided into 10 treatments with three replicates of 15 chicks per replicate. On day 14 of the experiment,...

introduction: nitric oxide (no), as a free radical, involves in several physiologic functions in gi tract such as nerve impulse transmission and vascular tonicity regulation. nitric oxide synthase (nos) is the enzyme for the production of no from l-arginine which in turn inhibits by l-ngnitroarginine methyl ester (l-name). in the current work, we aimed to evaluate morphometric analysis of duode...

anatomical variations of duodenum such as atresia, stenosis, and variations in shape have been described by various authors, but the existence of a gross anomaly in shape and position of midgut segment of the duodenum is rare. few reported cases of duodenal anomalies date back to early twentieth century. in the wake of advancement of imaging techniques and minimal access surgeries, authors repo...

peptic ulcer disease and its complications have long been studied but the coexistence of two major complications in a kissing ulcer is uncommon. we present our experience with this entity and review the related literature. a 27 year old man was suffering from concomitant major complication of duodenal kissing ulcer, huge anterior perforation and uncontrolled posterior bleeding, presenting as he...

An experiment was conducted to study the effect of different levels cinnamon essential oil (CEO) on oxidative stress indices, immune response and intestinal morphology broiler chickens. Day old chicks (n=180) were randomly allocated six dietary groups. Control group (T0) fed basal diet without antibiotic growth promoter (AGP), Group 2 with AGP (T1) while containing graded level CEO (200, 300, 4...

This study was performed to investigate the effects of antibiotic, organic acid, probiotic and prebiotic supplementation on performance, egg shell quality, pH value of gastrointestinal (GI) tract and small intestinal morphology of laying hens. The experiment was a completely randomized design with 160 laying hens strain (W-36) from 32 to 42 weeks of age, with five treatments, four replicates an...

Genetic selection based on rapid growth rates, improved feed conversion, and increased body weights has led to a predisposition to ascites in broiler populations. Sire-family selection was applied to a commercial elite line to produce divergent lines of ascites-resistant (RES) and ascites-susceptible (SUS) broilers by the 8th generation. One objective of this research was to determine the effec...
