“…ACTH, through stimulating the production of glucocorticoids, participates in regulating stress responses and metabolic processes. Previous findings [49, 50] in poultry suggested that the ACTH levels in LRFI chickens were significantly lower than those in HRFI chickens, which is consistent with our research results. LEP is a hormone secreted by adipose tissue that reduces food intake by stimulating the satiety center.…”

“…INS is the only hormone in the body that lowers blood glucose levels and promotes glycogen, fat and protein synthesis. Studies have found that the LRFI group has higher concentrations of INS, and this may be due to the relationship between INS expression and visceral fat deposition [50] . However, Karisa et al found a tendency toward higher INS concentrations in HRFI individuals [52] .…”

The RFI is independent of growth traits and selecting individuals with low RFI can improve feed efficiency without affecting the laying performance and egg quality of hens. In this study it was found that under similar egg production rates hens in the HRFI group had lower nutrient digestion capacity disrupted lipid metabolism and lower feed utilization efficiency than those in the LRFI group. Further research and validation are needed to investigate the effects of AST HDL-C and ACTH on feed efficiency in the late laying period through serum biochemical index analysis. Through multiomics analysis genes such as ADCY2 ADCY8 CCKAR ACSS2 FABP1 and FABP4 and metabolites such as LysoPI(18:2(9Z,12Z)/0:0) were identified as key genes and biomarkers related to RFI in laying hens during the late laying period. These findings are important for developing strategies to improve feed efficiency in Rhode Island Red pure-line chickens during the late laying period. Additionally in-depth investigations such as histological observations enzyme activity analysis and integration of multiomics techniques are needed to unravel the physiological and biochemical mechanisms of digestive organs that impact feed utilization efficiency in poultry.

“…At the genus level, the abundances of Megamonas in the group LRFI were higher than in the HRFI and the abundances of Anaerobiospirillum in the group LRFI were lower than in the HRFI. A study speculate that Megamonas and Anaerobiospirillum may be involved in fat deposition and energy metabolism (Wang and Kadarmideen, 2019;Li et al, 2022). In our experiment, Rikenellaceae and Ruminococcus_2, etc.…”

“…The abundance of Anaerobiospirillum was significantly positively correlated with Norsanguinarine, (3-[4-[2-3.5,7trihydroxy-6-3,4-dihydro-2H-1-benzopyran-2-yllphenyl) oxidanesulfonic acid, (−)-11-hydroxy-9,10-dihydrojasmonic acid 11-beta-Dglucoside and (4-{2-hexatriaconta-16,24,26,28-tetraen-12-yl] propyl}-2-hydroxycyclohexyl) oxidanesulfonic acid Dextrin D-Ribose. Anaerobiospirillum may reduce fat deposition (Li et al, 2022), and studies have found that it is significantly enriched in the cecum of lean ducks compared to Peking ducks (Yang et al, 2022). Lactobacillus can improve the feed efficiency of chickens (Gao et al,FIGURE 6 The rectal metabolomics pathway of two groups of laying ducks with different residual feed intake was analyzed.…”

IntroductionResidual feed intake (RFI) is a indicator to evaluate animal feed. This experiment was explored to study the relationship between intestinal microbiome and metabolome of ducks with different residual feed intake during laying period.MethodsA total of 300 Shaoxing ducks aged 42 weeks were randomly selected and fed a diet of 60 d. At the end of the trial, 20 samples were selected according to the phenotype of RFI and divided into two groups (HRFI and LRFI). The cecal microbiota composition was explored by 16S ribosomal RNA gene sequencing and rectal metabolomics uses liquid chromatography-mass spectrometry (LC–MS) to identify the composition of metabolites in a non-targeted manner.ResultsResults show feed intake and feed conversion ratio in the group HRFI were significantly higher than those in the group LRFI (p < 0.05). Chao1 indices were higher in the group LRFI than in the HRFI (p < 0.05), Shannon and Simpson indices were higher in the group LRFI than in the HRFI (p < 0.01). After linear discriminant analysis effect size (p < 0.05, LDA score > 3), Rikenellaceae, Rikenellaceae_RC9_gut_group, Lactobacillales and Ruminococcus_2, etc. were significantly enriched in the group LRFI at the genus level, while Prevotellaceae_NK3B31_group and Bacteria were significantly enriched in the group HRFI. After LC–MS analysis we found 338 metabolic difference products and 10 metabolic pathways, including the ABC transporter system, cysteine and methionine metabolism, arginine and proline metabolism, and vitamin B6 metabolism, were identified to be associated with the significantly differentially expressed between the groups LRFI and HRFI (p < 0.05). We hypothesize that the difference between ducks with different RFIs is mainly due to the fact that ducks with LRFI have more SCFAs-producing bacteria in their gut microorganisms, which regulate the RFI of animals. This process we found that Phascolarctobaterium and Anaerobiospirillum may provide energy for ABC transporter system by producing SCFAs, and regulate RFI to improve feed utilization efficiency.DiscussionThese results revealed the relationship between microbiome and metabonomics in laying ducks with different RFI, and provided theoretical basis for further study on the relationship between them.

“…Meanwhile, goose is a well-known herbivore that can utilize 40% to 50% dietary crude fiber ( Du, 2011 ), and gut microbiota plays central roles in this process. Although both the cecal and fecal microbiota of goose have been evaluated in the previous researches ( Gao et al, 2016 ; Xiang et al, 2019 ; Liu et al, 2020 ; Li et al, 2022 ; Xi et al, 2022 ), the foregut microbiota is also vital for nutrient digestion and well-being but have attracted less attentions ( Chen, 2005 ). More importantly, the systematic and comprehensive insights into the alternations in microbial compositions and structures in different gastrointestinal ( GI ) locations of goose can advance the understanding of the microbial regional distribution and gradual changing pattern, then paving the way for further studies related to growth performance improvement via gut microbial modulation.…”
