Aflatoxin B1 as a complicit in intestinal damage caused by Eimeria ovinoidalis in lambs: Novel insights to reveal parasite-gut battle. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 947:174539. [PMID: 38977103 DOI: 10.1016/j.scitotenv.2024.174539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 06/25/2024] [Accepted: 07/04/2024] [Indexed: 07/10/2024]
Abstract
Mycotoxins, unavoidable contaminants in feed and feed ingredients, have the potential to influence the incidence and severity of various diseases upon ingestion. Sheep coccidiosis is an enteric disease caused by protozoa of Eimeria spp. However, the extent to which the presence of aflatoxin b1 (AFB1) synergistically exacerbates damage to intestinal health in lambs with Eimeria remains unclear. 50-day-old female lambs were randomly assigned to a 2 × 2 factorial arrangement of treatments for 15 days to assess the impact of AFB1 exposure on lambs with or without Eimeria (E.) ovinoidalis infection. Our findings reveal that AFB1 synergistically intensifies damage to intestinal health in lambs challenged by E. ovinoidalis. This is evidenced by disruptions to the intestinal microbiota and reductions in the production of short-chain fatty acids. AFB1 further aggravates damage to the cecal mechanical barrier. Additionally, AFB1 contributes to the entry of lipopolysaccharide into the bloodstream, activating the inflammatory response. Interestingly, AFB1 exposure history results in an early peak of oocyst excretion and a decreased number of oocyst excretion in E. ovinoidalis infected lambs. This may be closely linked to the destruction of the intestinal epithelial cell structure and its apoptosis, as indicated by a decreased ratio of Bcl-2 to Bax and increased caspase-3 levels. Mechanistically, proteomics analysis identified mitochondrial dysfunction (inhibition of the oxidative phosphorylation pathway) as the primary factor intensifying intestinal epithelial cell destruction caused by coccidia, exacerbated by AFB1 through the inhibiting the conversion of NADH to NAD+ in the cecum of lambs via down-regulation of the PGC-1α/NRF1/TFAM pathway. Overall, these results offer novel insights into the AFB1 complicity in accelerating intestinal damage caused by E. ovinoidalis in lambs. Targeting the mitochondrial oxidative phosphorylation pathway of the intestine may represent a new therapeutic strategy against the detrimental effects of mycotoxin and coccidia.

Abstract
PURPOSE Previous studies have suggested a potential association between gut microbiota and neurological and psychiatric disorders. However, the causal relationship between gut microbiota and cognitive performance remains uncertain. METHODS A two-sample Mendelian randomization (MR) study used SNPs linked to gut microbiota (n = 18,340) and cognitive performance (n = 257,841) from recent GWAS data. Inverse-variance weighted (IVW), MR Egger, weighted median, simple mode, and weighted mode were employed. Heterogeneity was assessed via Cochran's Q test for IVW. Results were shown with funnel plots. Outliers were detected through leave-one-out method. MR-PRESSO and MR-Egger intercept tests were conducted to address horizontal pleiotropy influence. LIMITATIONS Limited to European populations, generic level, and potential confounding factors. RESULTS IVW analysis revealed detrimental effects on cognitive perfmance associated with the presence of genus Blautia (P = 0.013, 0.966[0.940-0.993]), Catenibacterium (P = 0.035, 0.977[0.956-0.998]), Oxalobacter (P = 0.043, 0.979[0.960-0.999]). Roseburia (P < 0.001, 0.935[0.906-0.965]), in particular, remained strongly negatively associated with cognitive performance after Bonferroni correction. Conversely, families including Bacteroidaceae (P = 0.043, 1.040[1.001-1.081]), Rikenellaceae (P = 0.047, 1.026[1.000-1.053]), along with genera including Paraprevotella (P = 0.044, 1.020[1.001-1.039]), Ruminococcus torques group (P = 0.016, 1.062[1.011-1.115]), Bacteroides (P = 0.043, 1.040[1.001-1.081]), Dialister (P = 0.027, 1.039[1.004-1.074]), Paraprevotella (P = 0.044, 1.020[1.001-1.039]) and Ruminococcaceae UCG003 (P = 0.007, 1.040[1.011-1.070]) had a protective effect on cognitive performance. CONCLUSIONS Our results suggest that interventions targeting specific gut microbiota may offer a promising avenue for improving cognitive function in diseased populations. The practical application of these findings has the potential to enhance cognitive performance, thereby improving overall quality of life.

Impact of the arginine silicate inositol complex on bone metabolism in broiler chickens with tibial dyschondroplasia caused by manganese deficiency. Br Poult Sci 2024:1-10. [PMID: 38598261 DOI: 10.1080/00071668.2024.2332724] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 02/27/2024] [Indexed: 04/11/2024]
Abstract
1. Tibial dyschondroplasia (TD) is a skeletal disorder in broilers that has financial implications, necessitating dietary modifications to reduce the prevalence of this disease. This study explored how arginine silicate inositol complex (ASI) supplementation affected tibial growth plate (TGP) and overall bone health in broilers with manganese (Mn) deficiency-induced TD.2. A total of 240 broiler chicks were divided into four groups, each consisting of 60 birds (15 replicates of four broilers each) as follows: i) Control, with 60 mg Mn per kg of diet; ii) ASI, with 60 mg Mn and 1 g ASI per kg of diet; iii) TD, with 22 mg Mn per kg of diet, and iv) TD+ASI, with 22 mg Mn and 1 g ASI per kg of diet.3. It was found that ASI supplementation increased tibial bone length in Mn-deficient TD broilers (p = 0.007). There was no Mn x ASI interaction for other bone morphometry variables (p > 0.05). However, both tibial bone mineral content and density were affected by Mn and ASI (p < 0.05). With ASI supplementation, serum bone-specific alkaline phosphatase and osteocalcin levels were elevated in the TD+ASI group compared to the TD group (p < 0.001). In the TD group, osteoprotegerin (OPG) levels in the TGP decreased compared to the control groups (p < 0.001).4. In contrast, ASI supplementation in the TD broilers counteracted the decrease in OPG compared to TD broilers without ASI supplementation (p < 0.001). The Mn level and ASI supplementation significantly influenced the OPG/receptor activator of the nuclear factor-κB ligand ratio (p < 0.001).5. In conclusion, the results demonstrated that inclusion of ASI in broiler diets could enhance bone formation variables by controlling OPG levels in the TGP, potentially serving as an effective method to decrease the occurrence of TD.

Poult Sci 2024; 103:103534. [PMID: 38401226 PMCID: PMC10906518 DOI: 10.1016/j.psj.2024.103534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 01/16/2024] [Accepted: 02/03/2024] [Indexed: 02/26/2024] Open
Abstract
The poultry skeletal system serves multiple functions, not only providing structural integrity but also maintaining the balance of essential minerals such as calcium and phosphorus. However, in recent years, the consideration of skeletal traits has been overlooked in the selective breeding of broilers, resulting in an inadequate adaptation of the skeletal system to cope with the rapid increase in body weight. Consequently, this leads to lameness and bone diseases such as tibial dyschondroplasia (TD), which significantly impact the production performance of broilers. Accumulating evidence has shown that microRNAs (miRNA) play a crucial role in the differentiation, formation, and disease of cartilage. However, the miRNA-mediated molecular mechanism underlying chicken TD formation is still poorly understood. The objective of this study was to investigate the biological function and regulatory mechanism of miRNA in chicken TD formation. Based on transcriptome sequencing of tibial cartilage in the healthy group and TD group, miR-206a-3p was found to be highly expressed in TD cartilage. The function of miR-206a-3p was explored through the transfection test of miR-206a-3p mimics and miR-206a-3p inhibitor. In this study, we utilized qRT-PCR, CCK-8, EdU, western blot, and flow cytometry to detect the proliferation, differentiation, and apoptosis of chondrocytes. The results revealed that miR-206a-3p suppressed the proliferation and differentiation of TD chondrocytes while promoting their programmed cell death. Furthermore, through biosynthesis and dual luciferase assays, it was determined that BMP6 was the direct target gene of miR-206a-3p. This finding was further supported by rescue experiments which confirmed the involvement of BMP6 in the regulatory pathway governed by miR-206a-3p. Our results suggest that miR-206a-3p can inhibits the proliferation and differentiation promote apoptosis through the target gene BMP-6 and suppressing the Smad2/3 signaling pathway in chicken TD chondrocytes.

Effects of Clostridium tyrobutyricum on Lipid Metabolism, Intestinal Barrier Function, and Gut Microbiota in Obese Mice Induced by High-Fat Diet. Nutrients 2024; 16:493. [PMID: 38398817 PMCID: PMC10893108 DOI: 10.3390/nu16040493] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 02/02/2024] [Accepted: 02/06/2024] [Indexed: 02/25/2024] Open
Abstract
Obesity and its complications constitute a main threat to global human health. The purpose of this investigation was to explore the influences of Clostridium tyrobutyricum (Ct) on lipid metabolism, intestinal barrier function, and intestinal microbiome in obese mice induced by a high-fat diet (HFD). After establishing the obesity model, 107 CFU/mL and 108 CFU/mL C. tyrobutyricum were used to intervene in HFD-fed mice by gavage for six weeks, and indexes related to obesity were measured. In the liver of HFD-fed mice, the results revealed that C. tyrobutyricum reduced liver weight and the levels of triglyceride (TG), total cholesterol (TC), and nonesterified fatty acid (NEFA), along with decreasing red lipid droplets and fat vacuoles. After C. tyrobutyricum intervention, the mRNA expression of peroxisome proliferator-activated receptor-γ (PPARγ) was downregulated, and AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptor-α (PPARα), adipose triglyceride lipase (ATGL), and hormone-sensitive lipase (HSL) were upregulated in the liver. Additionally, C. tyrobutyricum alleviated intestinal morphology injury caused by HFD, decreased the expression of tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6), and IL-1β in the colon, and upregulated tight junction protein expression. In addition, 16S rRNA sequencing revealed that C. tyrobutyricum increases the diversity of intestinal microbiota. Overall, C. tyrobutyricum improved HFD-induced lipid metabolism disorders, preserved the intestinal barrier's integrity, and modulated the structure of the intestinal microbiome. These findings provide a novel insight into the role of C. tyrobutyricum as a probiotic in regulating lipid metabolism.

Abstract
Growing evidence of fecal microbiota transplantation (FMT) and fecal virus transplantation (FVT) provides a possibility to regulate animal health, whereas little is known about the impact of the 2 methods. This study aimed to investigate the effects of gut microbes on jejunal function in healthy broiler chickens, with the objective of establishing a theoretical basis for the application of FMT and FVT. Cecal feces from 28-day-old AA broilers were collected to prepare gavage juice for FMT and FVT. FMT for Group FM, FVT for group FV and PBS gavage for group CON, continuously treated for 6 days start at 5-day-old chicks. Samples were collected at d 11 and d 21. The results showed that the treatment d 2 and the overall fecal score in treatment groups were significantly lower than CON group (P < 0.05). The jejunum morphology showed that FMT increased crypt depth, decreased villus height, V/C (P < 0.05) and FVT increased villus height (P < 0.05) at d 11. At d 21, villus height and crypt depth significantly higher (P < 0.05) in group FM and group FV. The expression of Claudin1, Occludin, ZO2, and Muc2 in the FV group was significantly increased (P < 0.05) at 11-day-old. FMT increased the secretion of sIgA at 11-day-old, and this influence lasted up to 21-day-old (P < 0.05). At 11-day-old, the expression of b0+AT of basic amino acid transport carrier and chymotrypsin activity (P < 0.05) had a significant correlation. At 21 d of age, FVT significantly increased the expression of PepT1 and SGLT1 (P < 0.05). At 11-day-old, FM group showed significantly higher faith pd index (P = 0.004) and Shannon index (P = 0.037), and separated from FV and CON according to PCoA. Among differentiating bacteria, Bacteroides significantly enriched (P < 0.05) in group FM, which positively correlated with the expression of ZO2, Muc2, Occludin, and Claudin1; R_Ruminococcus, L_Ruminococcus, Butyricicoccuss significantly enriched (P < 0.05) in group CON, which significantly higher than processing groups, R_Ruminococcus and L_Ruminococcus negatively correlated with the expression of Occludin (P < 0.05), and R_Ruminococcus, Butyricicoccus negatively correlated with the expression of Claudin1 (P < 0.05). At 21-day-old, PCoA based on Bray-Curtis shows that microbes taxa of 3 groups are isolated with each other and treatment groups were significant different with CON group based on Unweighted UniFrac and weighted UniFrac. The expression of PepT1 was significantly negatively (P < 0.05) correlated with Ruminococcus, and the expression of sIgA was significantly negatively (P < 0.05) correlated with Parabacteroides. In conclusion, FMT regulated intestinal flora rapidly, while it had little effect on intestinal function and a higher potential damaging risk on jejunal. FVT regulated intestinal flora structure softer, improved tight junction expression, but the mechanism of action needs further exploration.

Abstract
Coccidiosis is an intestinal protozoan disease of sheep, that causes substantial economic losses in the industry due to its intestinal protozoan origins. Many anti-protozoan drugs including ionophores, triazines, and sulfonamides have been widely used to treat sheep coccidiosis. Still, anticoccidial resistance and drug residues in edible tissues have prompted an urgent search for alternatives. In this study, the anti-coccidial effectiveness of the Radix dichroae extract was compared to that of the conventional anti-coccidial drug diclazuril. Here, eighteen 45-day-old lambs naturally-infected with Eimeria spp. were randomly allocated in three groups: control group, Radix dichroae extract group and diclazuril group. The results showed that the body weight gain (BWG) during the treatment and withdrawal periods was considerably improved in the coccidiosis-infected sheep treated with Radix dichroae extract and diclazuril compared to the control group, respectively. Additionally, the Radix dichroae extract and diclazuril had fewer oocysts per gram (OPG) than the control group, showing similar anti-coccidial effects on days 14, 21, 28, 35 and 78, respectively. Furthermore, Radix dichroae extract and diclazuril treatment altered the structure and composition of gut microbiota, promoting the relative abundance of Actinobacteriota, Firmicutes, Alistipes, and Bifidobacterium, while decreasing the abundance of Bacteroidota, Marinilaceae, Helicobacteraceae, and Prevotella. Moreover, Spearman's correlation analysis further revealed a correlation between the OPG and BWG and gut microorganisms. Collectively, the results indicated that Radix dichroae extract had similar anti-coccidial effects as diclazuril, and could regulate gut microbiota balance in growing lambs.

Wang L, Nabi F, Yi W, Wang D, Zhu Y, Jiang X. Low-dose thiram exposure elicits dysregulation of the gut microbial ecology in broiler chickens. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2024; 270:115879. [PMID: 38157796 DOI: 10.1016/j.ecoenv.2023.115879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 12/17/2023] [Accepted: 12/20/2023] [Indexed: 01/03/2024]
Abstract
Thiram, a typical fungicide pesticide, is widely used in agricultural production. The presence of thiram residues is not only due to over-utilization, but is also primarily attributed to long-term accumulation. However, there is a paucity of information regarding the impact of prolonged utilization of thiram at low doses on the gut microbiota, particularly with respect to gut fungi. Our objective is to explore the effect of thiram on broilers from the perspective of gut microbiota, which includes both bacteria and fungi. We developed a long-term low-dose thiram model to simulate thiram residue and employed 16 S rRNA and ITS gene sequencing to investigate the diversity and profile of gut microbiota between group CC (normal diet) and TC (normal diet supplemented with 5 mg/kg thiram). The results revealed that low doses of thiram had a detrimental effect on broiler's growth performance, resulting in an approximate reduction of 669.33 g in their final body weight at day 45. Our findings indicated that low-dose thiram had a negative impact on the gut bacterial composition, leading to a notable reduction in the abundance of Merdibacter, Paenibacillus, Macrococcus, Fournierella, and Anaeroplasma (p < 0.05) compared to the CC group. Conversely, the relative level of Myroides was significantly increased (p < 0.05) in response to thiram exposure. In gut fungi, thiram significantly enhanced the diversity and richness of gut fungal populations (p < 0.05), as evidenced by the notable increase in alpha indices, i.e. ACE (CC: 346.49 ± 117.27 vs TC: 787.27 ± 379.14, p < 0.05), Chao 1 (CC: 317.63 ± 69.13 vs TC: 504.85 ± 104.50, p < 0.05), Shannon (CC: 1.28 ± 1.19 vs TC: 5.39 ± 2.66, p < 0.05), Simpson (CC: 0.21 ± 0.21 vs TC: 0.78 ± 0.34, p < 0.05). Furthermore, the abundance of Ascomycota, Kickxellomycota, and Glomeromycota were significantly increased (p < 0.05) by exposure to thiram, conversely, the level of Basidiomycota was decreased (p < 0.05) in the TC group compared to the CC group. Overall, this study demonstrated that low doses of thiram induced significant changes in the composition and abundance of gut microbiota in broilers, with more pronounced changes observed in the gut fungal community as compared to the gut bacterial community. Importantly, our findings further emphasize the potential risks associated with low dose thiram exposure and have revealed a novel discovery indicating that significant alterations in gut fungi may serve as the crucial factor contributing to the detrimental effects exerted by thiram residues.

Poult Sci 2023; 102:103044. [PMID: 37717480 PMCID: PMC10507442 DOI: 10.1016/j.psj.2023.103044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 08/12/2023] [Accepted: 08/15/2023] [Indexed: 09/19/2023] Open
Abstract
Skeletal disorder is of concern to the poultry industry as it affects animal welfare and production performance. Traditional Chinese medicine could improve bone quality and reduce the incidence of bone disease, but the molecular regulation of Chinese medicine formula (CMF) on improving bone quality in broilers is still unclear. This study was performed to research the effects of CMF on skeletal performance of Cobb broilers and reveal the molecular regulation. A total of 120 one-day-old Cobb broilers were randomly allocated into 4 equal groups of 30 chickens, with 5 replicates and 6 chickens in each replicate. The control (CON) group was fed a diet without CMF, while the CMF1, CMF2, and CMF3 groups were supplemented with different CMF at 6,000 mg/kg diet, respectively. The broilers were raised to 60 d of age, then bone tissues were collected for biomechanical properties, micro-CT detection and transcriptomic sequencing analysis. The results showed that CMF3 improved the biomechanical properties of broiler tibia, via increasing the elastic modulus (P < 0.05), yield strength (P > 0.05), maximum stress (P < 0.05) and fracture stress (P < 0.05) of the tibia. Micro-CT analysis indicated that CMF3 increased the bone mineral density (BMD), bone volume/total volume (BV/TV), bone surface density (BS/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), and decreased the trabecular separation (Tb.Sp) of femur cancellous bone (P < 0.05). RNA-seq analysis revealed 2,177 differentially expressed genes (DEGs) (|log2FoldChange| ≥ 1, FDR < 0.05) between the CMF3 group and CON group. Kyoto Encyclopedia of Genes and Genomes pathway (KEGG) analysis showed 13 pathways mostly associated with bone growth and development and bone metabolism, and we identified 39 bone-related DEGs. This study suggests that CMF3 could improve bone strength and bone microstructure of broilers, and showed a positive effect on bone performance. Our research could provide a theoretical reference for the development of pollution-free feed additives to improve the skeletal performance of broilers, which could help promote healthy farming of chickens.

Comparative analysis of the gut microbiota of wild wintering whooper swans (Cygnus Cygnus), captive black swans (Cygnus Atratus), and mute swans (Cygnus Olor) in Sanmenxia Swan National Wetland Park of China. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:93731-93743.

Abstract
The gastrointestinal microbiota, a complex ecosystem, is involved in the physiological activities of hosts and the development of diseases. Birds occupy a critical ecological niche in the ecosystem, performing a variety of ecological functions and possessing a complex gut microbiota composition. However, the gut microbiota of wild and captive birds has received less attention in the same region. We profiled the fecal gut microbiome of wild wintering whooper swans (Cygnus Cygnus; Cyg group, n = 25), captive black swans (Cygnus Atratus; Atr group, n = 20), and mute swans (Cygnus Olor; Olor group, n = 30) using 16S rRNA gene sequencing to reveal differences in the gut microbial ecology. The results revealed that the three species of swans differed significantly in terms of the alpha and beta diversity of their gut microbiota, as measured by ACE, Chao1, Simpson and Shannon indices, principal coordinates analysis (PCoA) and non-metricmulti-dimensional scaling (NMDS) respectively. Based on the results of the linear discriminant analysis effect size (LEfSe) and random forest analysis, we found that there were substantial differences in the relative abundance of Gottschalkia, Trichococcus, Enterococcus, and Kurthia among the three groups. Furthermore, an advantageous pattern of interactions between microorganisms was shown by the association network analysis. Among these, Gottschalkia had the higher area under curve (AUC), which was 0.939 (CI = 0.879-0.999), indicating that it might be used as a biomarker to distinguish between wild and captive black swans. Additionally, PICRUSt2 predictions indicated significant differences in gut microbiota functions between wild and captive trumpeter swans, with the gut microbiota functions of Cyg group focusing on carbohydrate metabolism, membrane transport, cofactor, and vitamin metabolism pathways, the Atr group on lipid metabolism, and the Olor group on cell motility, amino acid metabolism, and replication and repair pathways. These findings showed that the gut microbiota of wild and captive swans differed, which is beneficial to understand the gut microecology of swans and to improve regional wildlife conservation strategies.

Total Flavonoids of Rhizoma Drynariae Mitigates Aflatoxin B1-Induced Liver Toxicity in Chickens via Microbiota-Gut-Liver Axis Interaction Mechanisms. Antioxidants (Basel) 2023; 12:antiox12040819. [PMID: 37107194 PMCID: PMC10134996 DOI: 10.3390/antiox12040819] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Revised: 03/21/2023] [Accepted: 03/24/2023] [Indexed: 03/30/2023] Open
Abstract
Aflatoxin B1 (AFB1) is a common mycotoxin that widely occurs in feed and has severe hepatotoxic effects both in humans and animals. Total flavonoids of Rhizoma Drynaria (TFRD), a traditional Chinese medicinal herb, have multiple biological activities and potential hepatoprotective activity. This study investigated the protective effects and potential mechanisms of TFRD against AFB1-induced liver injury. The results revealed that supplementation with TFRD markedly lessened broiler intestinal permeability by increasing the expression of intestinal tight junction proteins, as well as correcting the changes in gut microbiota and liver damage induced by AFB1. Metabolomics analysis revealed that the alterations in plasma metabolites, especially taurolithocholic acid, were significantly improved by TFRD treatment in AFB1-exposed chickens. In addition, these metabolites were closely associated with [Ruminococcus], ACC, and GPX1, indicating that AFB1 may cause liver injury by inducing bile acid metabolism involving the microbiota–gut–liver axis. We further found that TFRD treatment markedly suppressed oxidative stress and hepatic lipid deposition, increased plasma glutathione (GSH) concentrations, and reversed hepatic ferroptosis gene expression. Collectively, these findings indicate that ferroptosis might contribute to the hepatotoxicity of AFB1-exposed chickens through the microbiota–gut–liver axis interaction mechanisms; furthermore, TFRD was confirmed as an herbal extract that could potentially antagonize mycotoxins detrimental effects.
