Campylobacter jejuni infection induces dynamic expression of avian host defense peptides in vitro and in vivo.

Campylobacter jejuni is considered as the leading cause of worldwide foodborne bacterial gastroenteritis. Chicken is the main reservoir of C. jejuni.

Effect of β-1,3/1,6-glucan on gut microbiota of yellow-feathered broilers.

β-1,3/1,6-glucan as a prebiotic improves immune performance in animals. These functions are closely related to the effect of β-1,3/1,6-glucan on gut microbiota structure. However, the effect of β-1,3/1,6-glucan on the gut microbiota structure of broilers is unclear.

Antimicrobial resistance surveillance of from chickens in the Qinghai Plateau of China.

Antimicrobial resistance (AMR) may lead to worldwide epidemics through human activities and natural transmission, posing a global public safety threat. Colistin resistance mediated by the 1 gene is the most prevalent among animal-derived , and 1-carrying have been frequently detected in central-eastern China. However, animal-derived with AMR and the prevalence of -1 in the Qinghai Plateau have been rarely investigated.

The effect of bile salt diet supplementation on genes related to fat metabolism in yellow-feathered broilers.

Background And Aim: As a new feed additive, bile acid (BA) can promote the absorption and transport of lipids and fat-soluble vitamins. In recent years, BAs have been widely used in animal feed to promote fat absorption. Therefore, this study aimed to investigate the effect of bile salt supplementation in the diet of yellow-feathered broilers on messenger RNA (mRNA) expression of sterol regulatory element-binding protein 1 (SREBF1), fatty acid synthase (FAS), acetyl-coenzyme A carboxylase (ACC), and fatty acid transport protein 4 (FATP4).

Effects of different feeding regimes on muscle metabolism and its association with meat quality of Tibetan sheep.

This study aimed to explore the effects of different feeding regimes on muscle metabolism and its association with meat quality of Tibetan sheep through correlation analysis of meat quality and differential metabolites using untargeted and targeted metabolomics. The untargeted metabolome was detected by UHPLC-QTOF-MS, and the targeted metabolome was detected by UHPLC-QQQ-MS (amino acids) and GC-MS (fatty acids). Based on the researched results, the nutritional quality of meat, including the content of protein and fat and the edible quality of meat, including tenderness, water holding capacity (WHC), texture, and flavor of Tibetan sheep were superior in the stall-feeding group (GBZ) than in the traditional grazing group (CBZ).

The effect of as a dietary supplement on blood parameters, intestinal morphology, and gut microflora in Haidong chicks reared in a high altitude environment.

Aim: The effects of the inclusion of in the diet of Haidong chicks reared in the Qing-Zang high altitude area (China) under hypoxic conditions.

Materials And Methods: A total of 720 Haidong chicks were randomly divided into six groups and fed diets supplemented with 0%, 0.5%, 0.

Effects of inulin diet supplementation on production performance, gut traits, and incidence of ascites in Haidong chicks under hypoxic conditions.

Objective: Effects of inulin supplementation in diet of Haidong chicks under hypoxic conditions on production performance, intestinal morphologic change, microflora contents and the incidence of ascites were studied.

Methods: Commercial male chicks (360) were randomly divided into 6 groups and were fed diets supplemented with 0, 0.05, 0.

Effects of dietary yeast beta-1,3-1,6-glucan on growth performance, intestinal morphology and chosen immunity parameters changes in Haidong chicks.

Objective: This study investigated the effects of 1,3-1,6 beta-glucan added to the diet of Haidong chicks reared under hypoxic conditions, to ascertain the growth performances, immunity and intestinal morphology changes.

Methods: A total of 750 chicks were divided into five groups and fed diets containing 0.5g/kg, 1.

Pituitary adenylate cyclase-activating peptide (PACAP) immunoreactivity distribution in the small intestine of the adult New Hampshire chicken.

We conducted a study in which we demonstrated by means of immunoperoxidase and immunofluorescence methods the presence of pituitary adenylate cyclase-activating peptide 38 (PACAP-38) immunoreactivity in the small intestine of adult New Hampshire chickens and its co-localization with VIP. In particular we describe for the first time the presence of PACAP-positive cells in the epithelium of crypts and villi. Using double immunostaining, we observed that these two peptides were widely co-localized in the nerve structures of duodenum and jejunum with the exception of the ileum, where we noticed a faint co-localization regarding the nerve fibers of the lamina propria of the villi.
