“…Numerous studies on the gut microbiota of normal broilers have reported that Firmicutes and Bacteroidetes were the predominant intestinal phyla ( Chen et al, 2020 ; Das et al, 2020 ), which was also observed in the cecal contents of all broilers in our study. Firmicutes and Bacteroidetes have been confirmed to participate in the degradation and metabolism of nutrients, such as carbohydrate and indigestible complex polysaccharides, promoting nutrient absorption and energy capture from feed ingredients in animals ( Liu et al, 2018 ; Ouyang et al, 2019 ). In the current study, these two phyla occupied greater than 95% of the microbiota in cecum, which is the major microbial fermentative organ in poultry ( Vasai et al, 2014 ), suggesting their importance in feed utilization and host metabolism.…”

BackgroundThe Dendrobium officinale leaves (DOL) is an underutilized by-product with a large biomass, which have been shown to exhibit immunomodulatory and antioxidant functions. The purpose of this research was to investigate the effects of DOL on broiler growth performance, antioxidant status, immune function, and gut health.MethodsOne hundred and ninety-two 1-day-old chicks were selected and divided into 4 groups at random, 6 replicates for each group and 8 in each. Chicks were given a basal diet supplemented with different amounts of DOL: 0% (control group, NC), 1% (LD), 5% (MD), or 10% (HD). During the feeding trial (70 days), broiler body weight, feed intake, and residual feeding were recorded. On d 70, 12 broilers from each group were sampled for serum antioxidant and immune indexes measurement, intestinal morphological analysis, as well as 16S rRNA sequencing of cecal contents and short-chain fatty acid (SCFA) determination.ResultsIn comparison to the NC group, the LD group had greater final body weight and average daily gain, and a lower feed conversion ratio (p < 0.05, d 1 to 70). However, in MD group, no significant change of growth performance occurred (p > 0.05). Furthermore, DOL supplementation significantly improved the levels of serum total antioxidant capacity, glutathione peroxidase, superoxide dismutase, and catalase, but reduced the level of malondialdehyde (p < 0.05). Higher serum immunoglobulin A (IgA) content and lower cytokine interleukin-2 (IL-2) and IL-6 contents were observed in DOL-fed broilers than in control chickens (p <0.05). Compared to the NC group, duodenal villus height (VH) and villus height-to-crypt depth (VH:CD) ratio were considerably higher in three DOL supplementation groups (p < 0.05). Further, 16S rRNA sequencing analysis revealed that DOL increased the diversity and the relative abundance of cecal bacteria, particularly helpful microbes like Faecalibacterium, Lactobacillus, and Oscillospira, which improved the production of SCFA in cecal content. According to Spearman correlation analysis, the increased butyric acid and acetic acid concentrations were positively related to serum antioxidant enzyme activities (T-AOC and GSH-Px) and immunoglobulin M (IgM) level (p < 0.05).ConclusionOverall, the current study demonstrated that supplementing the dies with DOL in appropriate doses could enhance growth performance, antioxidant capacity, and immune response, as well as gut health by promoting intestinal integrity and modulating the cecal microbiota in broilers. Our research may serve as a preliminary foundation for the future development and application of DOL as feed additive in broiler chicken diets.

“…The Firmicutes may serve as a source of energy and have participated in the host's material and energy metabolism cycle ( Liu et al, 2018 ). Meanwhile, the Bacteroides participated in the metabolism of carbohydrate, polysaccharide and other nutrients which promoted nutrients absorption ( Ouyang et al, 2018 ). The Proteobacteria is a gram-negative bacterium that contains a variety of pathogens ( Liu et al, 2018 ).…”

“…Membros desta Família são estritamente anaeróbios, fermentadores e produzem principalmente ácido acético (MOROTOMI et al, 2012). Representantes do gênero Christensenellaceae_R-7_group foram identificados como predominantes em reatores anaeróbios com águas residuárias contendo compostos tóxicos, tais como giberelina (hormônio produzido por vegetais), hidrocarbonetos aromáticos policíclicos (OUYANG et al, 2019;TANG et al, 2019), além de sulfato e amônio. Smithella e Pseudomonas são anaeróbios facultativos, capazes de realizar clivagem de anéis aromáticos, ω-oxidação, β-oxidação, dessulfonação e oxidar propionato, crotonato, butirato, malato e fumarato em acetato, podendo assim realizar sintrofismo com arqueias metanogênicas (DE BOK et al 2001;KERTESZ et al, 1994;BRENNER et al, 2005).…”
