The authors carried out studies on 16 rabbits - 10 experimental and 6 control with implanted duodenal fistula. They poured for a period of 4 days through the fistula the duodenal content of 6 sick persons with acute and chronic relapsing pancreatitis into the duodenum of the experimental animals and the content of 2 healthy persons-to the animals of the control group. After each pouring the activity of pancreatic and intestinal enzymes was determined in sera and duodenal contents of the rabbits. The duodenum, pancreas, liver and kidneys were examined histomorphologically after killing the experimental animals. The obtained results showed that there were no changes in the enzyme activity and morphologic picture of the organs after pouring duodenal content of healthy persons. The enzyme activity was reduced in the duodenal content of the experimental animals, but in the sera was increased. Pancreatitis, duodenitis, fatty dystrophy of liver and parenchymatous dystrophy of kidneys was established histomorphologically. The authors suggest the appearance of some toxic substances in the duodenal content of sick persons with acute and chronic relapsing pancreatitis.

This study aimed to investigate the effects of reducing inorganic trace minerals (ITM) by supplementing compound organic trace minerals (OTM) chelates on growth performance, fecal mineral excretion, intestinal health, and cecal microbiota of yellow-feathered broilers. A total of 960 one day old male broilers were randomly assigned to 6 treatments, among which birds were fed with the basal diets (negative control, NC), or supplemented with 1,000 mg/kg (positive control, PC), 300, and 500 mg/kg ITM or OTM, respectively. Dietary supplementation of OTM significantly increased the average daily gain (ADG) during 22-53 d and 1-53 d, and reduced the fecal emissions of Fe, Cu, Zn, and Mn of Chinese yellow-feathered broilers (P < 0.

Background: Groove pancreatitis (GP) is a form of pancreatitis that affects the pancreaticoduodenal groove area, which lies between the head of the pancreas, the second part of the duodenum and the distal bile duct, presenting as abdominal pain and gastric outlet obstruction. In this study, we present the clinical and radiological characteristics of individuals diagnosed with groove pancreatitis at our center and discuss the use of a conservative treatment approach in managing GP.
Methods: The data of patients with groove pancreatitis treated at our center between January 2012 and December 2021 was analyzed.

Bamboo powder, a novel ingredient, is gaining recognition for its potential as a dietary supplement in poultry feed. This study aimed to investigate the effects of fermented bamboo powder (FBP) on antioxidant status, gut hormone activities, intestinal digestive enzyme activities, gut morphological structure, gastrointestinal development, and the expression of nutritional transporter genes in dwarf yellow-feather broiler chickens. A total of 600 healthy 1-day-old chicks were allocated randomly into two groups, with 10 replicates per group and 30 chicks in each replicate.

This study aimed to evaluate the effect of early weaning (EW) on the growth performance, gastrointestinal development, serum parameters, and metabolomics of Hu sheep lambs. Twenty-four male Hu lambs were initially ewe-reared. A total of 12 lambs were weaned at 30 d of age (D30) as the EW group, and the remaining 12 lambs were weaned at 45 d of age (D45) as the control (CON) group.

The aim of this study was to investigate the combination effects of α-glycerol monolaurate (GML) and glyceryl tributyrate (TB) on growth performance, nutrient digestibility, gut microbiota, and immune function in weaned piglets. A total of 120 weaned piglets with an average body weight (BW) of 6.88 kg were randomly allocated to one of the three dietary treatments: (1) CON: a basal diet; (2) 0.
