Colibacillosis caused by enterotoxigenic Escherichia coli (E. coli) results in economic losses the poultry industry. Antibiotics are usually used to control colibacillosis, however, E. has varying degrees of resistance different antibiotics. Therefore use probiotics is becoming accepted as an alternative In this study, we evaluated effects Clostridium butyricum (C. butyricum) on growth performance, immune response, intestinal barrier function, and digestive enzyme activity broiler chickens...

The effect of early feed restriction on metabolic programming and compensatory growth was studied in broiler chickens. A total 480 female 1-d-old birds (Aconred) were randomly allocated to ad libitum feed-restricted groups, each which replicated 6 times with 40 per replicate. Broilers provided commercial diets. Feed-restricted broilers deprived for 4 h day from 1 21 d age. Effects treatments determined at 63 In age, BW, average daily gain intake, breast muscle (P < 0.01), carcass yield...

Weaning stress in piglets can lead to poor health outcomes and reduced production.

1. This study was conducted to investigate the effects of methionine and betaine supplementation on growth performance, carcase composition lipid metabolism in growing broilers. 2. A total 450 commercial broilers, 22 d age, were randomly allocated three groups, each which included replicates (50 birds per replicate). The groups received same methionine-deficient diet supplemented with 0 or 1 g/kg methionine, 0·5 betaine, respectively. 3. Methionine significantly improved weight gain feed...

Abstract The present study investigated the effect of Bacillus subtilis DSM 29784 (Ba) and enzymes (xylanase β -glucanases; Enz), alone or in combination (BE) as antibiotic replacements, on growth performance, digestive enzyme activity, immune response intestinal barrier broiler chickens. In total, 1200 1-d-old broilers were randomly assigned to five dietary treatments, each with six replicate pens forty birds for 63 d follows: (a) basal diet (control), supplemented (b) 1 × 10 9...

Fecal microbiota transplantation (FMT) could shape the structure of intestinal in animals. This study was conducted to explore changes that happen and function caused by weaning stress, whether early-life FMT alleviate stress through modifying weaned piglets. Diarrheal (D) healthy (H) piglets were observed, same farm, a total nine litters newborn randomly allocated three groups: sucking normally (S), at 21 d (W), + (FW). The results demonstrated differences fecal existed group D H....

This study was conducted to investigate the effects of selenomethionine (Se-Met) and sodium selenite (SS) supplementation on meat quality, selenium (Se) distribution, antioxidant status in broilers. A total 360 seven-days-old Ross 308 broilers an average body weight 162 ± 0.59 g were randomly allotted three treatments, each which included replications 40 birds. The treatments a control diet containing 0.04 mg Se/kg other two diets that contained 0.15 supplemented by SS or Se-Met. experiment...

In total, 180 Lingnan Yellow broiler breeders were used to investigate the effect of different sources selenium (Se) on expression cellular glutathione peroxidase (GPx1) and cytoplasmic thioredoxin reductase (TrxR1) in liver kidney their offspring by quantitative real-time PCR. There 6 replicates 3 dietary treatments. Broiler fed corn-soy-based diets supplemented with 0.15 mg/kg Se from sodium selenite, Se-enriched yeast (SY), or selenomethionine (SM). At end feeding trial, mRNA levels GPx1...

Along with banning antibiotics, necrotic enteritis (NE), especially subclinical (SNE), poses a significant threat to the chicken industry; however, probiotics are potentially promising intervention. We aimed investigate beneficial effects of Bacillus subtilis DSM29784 (BS) on treatment Clostridium perfringens (CP)-induced SNE in broilers. A total 360 1-day-old broiler chicks were divided into three groups, namely control (Ctr), SNE, and BS (BST) all which fed basal died for 21days, then from...

Clostridium perfringens (C. perfringens) have been considered as one of the most common causes human and veterinary gastrointestinal diseases. Reuterin is a broad-spectrum antimicrobial agent produced by certain Lactobacillus reuteri (L. reuteri) strains. The present study showed that bioconversion reuterin from isolated probiotic L. (LR) 21 strain significantly inhibited bacterial growth downregulated expression virulence genes (p < 0.05). DCFH-DA staining assays exhibited ROS are essential...

Itaconic acid (IA), a metabolite generated by the tricarboxylic (TCA) cycle in eukaryotic immune cells, and its derivative dimethyl itaconate (DI) exert antibacterial functions intracellular environments. Previous studies suggested that IA DI only inhibit bacterial growth carbon-limited environments; however, whether maintain activity carbon-enriched environments remains unknown. Here, inhibited bacteria with minimum inhibitory concentrations of 24.02 mM 39.52 mM, respectively, environment....

The continuous expansion of intestinal stem cells (ISCs) is crucial for maintaining the renewal epithelium, particularly in inflammatory conditions. It remains largely unknown how internal microbiota repair damage to mucosal barrier. Hence, investigating potential anti-inflammatory probiotics from symbolic microbes broilers and analyzing their mechanism action support barrier function can offer novel regulatory tools alleviate broiler enteritis. In this research, we utilized vivo plus ex...

The present study was conducted to investigate the effects of different lighting regimens on broilers' growth performance, antioxidant status, and nonspecific immunity. A total 630 one-day-old Lingnan Yellow broilers were randomly divided into 3 treatments with replicates each (70 birds/replicate). Lighting schedules constant (CL), 24L:0D, 2 intermittent lightings (INL), 16L:2D:1L:2D:1L:2D (INL I) 17L:3D:1L:3D II), which provided by incandescent bulbs. trial split starter (1–21 d) finisher...

Summary Studies have found that a dietary supplement of Bacillus amyloliquefaciens improved the growth performance, increased nutrient digestibility hosts and modulated intestinal microflora. A total 360 1‐day‐old Ross broilers were randomly divided into three treatments: control group with basal diet, an antibiotic diet added colistin sulphate, probiotics . The HiSeq high‐throughput sequencing analysis 16S rRNA was used to investigate differences in birds’ caecal microflora, metabolomics...
