AI Article Synopsis
- - The study assessed the growth performance and gut microbiota differences in two rabbit breeds, Native Middle-Egypt (NMER) and Giant Flanders (GF), from 5 to 12 weeks of age, using 16S rRNA gene sequencing to analyze gut samples.
- - Results showed that GF rabbits had better growth metrics, such as weight gain and villus height in the jejunum, compared to NMER rabbits, with their gut microbiota exhibiting beneficial bacterial compositions.
- - Significant correlations were found between specific gut microbiota in the jejunum and cecum of different breeds and their weight gain, indicating that the healthy microbiota in GF may help mitigate pathogenic effects in these rabbits.
Article Abstract
This study aimed to evaluate the productive performance and microbiota variation in the jejunum and cecum of two rabbit breeds with different growth rates. This study was carried out on Native Middle-Egypt Breed (NMER) and Giant Flanders (GF) rabbits from 5 weeks to 12 weeks of age. Twenty NMER (NM) and GF male rabbits were slaughtered, and the jejunum and cecum tracts were collected to assay gut microbiota composition via 16S ribosomal RNA (rRNA) gene sequencing and histology examination. At 12 weeks of age, daily weight gain, villus height in the jejunum, total protein, and albumin were higher in GF rabbits than in NMER rabbits. Also, the jejunal villi of GF were well arranged in their dense borders. The microbiota between the jejunum and cecum was significantly different in terms of Beta-diversity. A significant correlation between (jejunum NM samples) and (cecum GF samples) with body weight and weight gain was found ( < 0.05). Moreover, Escherichia-Shigella in the cecum of NM was significantly correlated with weight gain ( < 0.05). The most abundant genera identified in the jejunal and cecal contents of GF were generally beneficial microbiota. They may also play a role in reducing the pathogenic effects of in these rabbits.

Low molecular weight galactomannan alleviates diarrhea induced by senna leaf in mice intestinal barrier improvement and gut microbiota modulation.
Food Funct

College of Food Science and Engineering, Ocean University of China, No. 1299 Sansha Road, Qingdao, 266404, China.
Low molecular weight galactomannan (LMGM), a soluble dietary fibre derived from guar gum, is recognized for its prebiotic functions, including promoting the growth of beneficial intestinal bacteria and the production of short-chain fatty acids, but the mechanism of alleviating diarrhea is not fully understood. This study established an acute diarrhea mouse model using senna leaf decoction and evaluated the therapeutic effects of LMGM by monitoring diarrhea scores, loose stool prevalence, intestinal tissue pathology and gene expression, and gut microbiota composition and metabolisms. The results indicated that LMGM significantly reduced diarrhea scores and loose stool prevalence within two hours post-treatment.

Introduction: The conjugative transfer of antibiotic resistance genes (ARGs) mediated by plasmids occurred in different intestinal segments of mice was explored.
Methods: The location of ARG donor bacteria and ARGs was investigated by qPCR, flow cytometry, and small animal imaging. The resistant microbiota was analyzed by gene amplification sequencing.
Comparison of two techniques to blind end jejunum and ileum for jejunocaecostomy in horses.

Department of Large Animal Clinical Sciences, College of Veterinary Medicine, University of Florida, Gainesville, Florida, USA.
Background: Jejunocaecostomy (JC) is frequently required to bypass diseased ileum as a side-to-side (SS) anastomosis with blind end closure of the small intestine. The effects of the blind end closure method on the performance of the anastomosis have not been studied.
Objectives: To compare handsewn and stapled blind end closures of the ileum and jejunum.

Introduction: The gastrointestinal microbiota profoundly influences the health and productivity of animals. This study aimed to characterize microbial community structures of the mouth, gastrointestinal tract (GIT), and feces of cattle.
Methods: Samples were collected from 18 Akaushi crossbred steers at harvest from multiple locations, including the oral cavity, rumen, abomasum, duodenum, jejunum, ileum, cecum, spiral colon, distal colon, and feces.
Effect of LK01 on Growth Performance, Antioxidant Capacity, Immunity, Intestinal Health, and Serum Biochemical Indices in Broilers.

This study aimed to investigate the effects of adding LK01 to the diet on the growth performance, antioxidant capacity, immunity, intestinal health, and serum biochemical indicators of broilers. This study selected 1080 one-day-old broiler chickens with similar body weight, and randomly divided them into six groups, with six replicates in each group and 30 chicks in each replicate. The chicks were fed (1) the basal diet (CON), (2) the basal diet with 10 CFU/kg LK01(T1), (3) the basal diet with 10 CFU/kg LK01(T2), (4) the basal diet with 10 CFU/kg LK01(T3), (5) the basal diet with 10 CFU/kg LK01(T4), and (6) the basal diet with 10 CFU/kg LK01(T5).
