“…Gut microbiomes are closely related to chicken performance, and studies have found that feed supplemented with Lactobacillus can increase chicken body weight ( Angelakis and Raoult, 2010 ). The abundance of Bacteroides and Bifidobacterium in the ileum was positively correlated with body weight ( Han et al, 2016 ), where Bacteroides may be utilised as a biomaker for feed efficiency ( Huang et al, 2021 ; Dittoe et al, 2022 ). Understanding the gut microbiome of yellow-feathered chickens contributes to the success of poultry meat production, which requires improved feed efficiency, increased muscle mass, and reduced abdominal fat ratio ( Zerehdaran et al, 2004 ).…”

Yellow-feathered chickens have great nutritional value and are widely and traditionally used in China, on an industrial scale as broilers. The presence of intestinal microbes has been shown to correlate with poultry performance and serves as an essential reservoir of antibiotic resistance genes (ARGs). Antibiotic resistance is a major public health concern. Here, we investigated functional characteristics of the gut microbiome of indigenous Chinese yellow-feathered chickens (the Huiyang Bearded, Xinghua, Huaixiang, Zhongshan Shanlan, Qingyuan Partridge, and Yangshan chickens) through metagenomic sequencing and reconstructed 409 draft genomes, including 60 novel species and 6 novel genera. Furthermore, we assessed the functions of the intestinal microbial communities and examined the ARGs within them. The results showed that the microbial populations of yellow-feathered broilers were primarily dominated by Bacteroidetes and Firmicutes at the phylum level and Bacteroides at the genus level. Furthermore, the Qingyuan Partridge chicken showed a significantly higher abundance of Prevotella than the other five breeds of chicken. Principal coordinates analysis indicated significant differences in the structures of microbial communities and ARGs, based on the binary Jaccard distance, among the six chicken breeds. Moreover, 989 ARGs conferring tetracycline, multidrug, and aminoglycoside resistance were identified, which represented more than 80% of the faecal resistomes; the most abundant gene in the yellow-feathered chickens was tet(Q). In addition, we found the greatest abundance of resistance genes in Xinghua chickens, indicating that Xinghua chickens are highly resistant to antibiotics. Overall, our findings revealed differences in the gut microbial community structure of indigenous Chinese yellow-feathered broiler breeds and the composition and characteristics of ARGs and antibiotic resistance that enabled us to reconstruct the yellow-feathered chicken gut microbial community genomes. The current data significantly improves our knowledge of the gut microbiome and antibiotic resistance of popular broiler breeds in China.

“…This nutritional supplement may support the increase of milk production under the same degree of adipose mobilization (plasma NEFA concentration). The gastrointestinal tract microbial metabolites generally contain VFA, lactate, bacteriocins, and so on [ 57 ]. A previous study found that lactate concentration was significantly increased and VFA concentrations were not changed in sterilized rumen fluid when compared with fresh rumen fluid [ 19 ].…”

Background The dairy cow’s postpartum period is characterized by dramatic physiological changes, therefore imposing severe challenges on the animal for maintaining health and milk output. The dynamics of the ruminal microbiota are also tremendous and may play a crucial role in lactation launch. We aim to investigate the potential benefits of early microbial intervention by fresh rumen microbiota transplantation (RMT) and sterile RMT in postpartum dairy cows. Twelve fistulated peak-lactation dairy cows were selected to be the donors for rumen fluid collection. Thirty postpartum cows were divided into 3 groups as the transplantation receptors respectively receiving 10 L fresh rumen fluid (FR), 10 L sterile rumen fluid (SR), or 10 L saline (CON) during 3 d after calving. Results Production performance, plasma indices, plasma lipidome, ruminal microbiome, and liver transcriptome were recorded. After fresh and sterile RMT, we found that the molar proportion of propionic acid was increased on d 7 in the FR and SR groups and the bacterial composition was also significantly changed when compared with the CON group. A similarity analysis showed that the similarities between the CON group and FR or SR group on d 7 were 48.40% or 47.85%, whereas the similarities between microbiota on d 7 and 21 in the FR and SR groups were 68.34% or 66.85%. Dry matter intake and feed efficiency were not affected by treatments. Plasma β-hydroxybutyrate concentration in the FR group was decreased and significantly different lipids mainly included phosphatidylcholine and lysophosphatidylcholine containing polyunsaturated fatty acids. Hepatic transcriptomics analysis indicated acute-phase response pathways were upregulated in the SR group. Conclusions Our study suggests that RMT can shorten the transition process of the ruminal microbiota of postpartum dairy cows with no benefit on dry matter intake or feed efficiency. Inoculation with rumen fluid may not be a useful approach to promote the recovery of postpartum dairy cows. Graphical Abstract

“…The MAG or MAG with Xylanase supplementation showed 20 to 21% unique ASV in the treatment groups on d3 and d35 ( Figure 8 ). Broiler performance is believed to be associated with the microbiota available in the gut ( Dittoe et al, 2022 ). In the study, when comparing CON, MAG, and MAG+XYN groups, SCFA-producing bacteria ( Lactobacillus, Monoglobus , torques group of Ruminococcus, Faecalibacterium, Ruminiclostridium ) were significantly higher in abundance in microalgae added groups.…”
