MicroRNAs (miRNAs) can post-transcriptionally regulate gene expression and studies in recent years have shown the importance of miRNA-associated gene regulation in S. aureus-induced mastitis. In this study, to investigate the role of miR-223 in mastitis, we performed experiments to overexpress and suppress miR-223 in an immortalized bovine mammary epithelial cell line (MAC-T) infected with S. aureus. Overexpression of miR-223 in MAC-T cells repressed cell apoptosis and necrosis induced by S. aureus infection, whereas suppression of miR-223 had the opposite effect. Transcriptome expression profiling with weighted gene co-expression network analysis (WGCNA) and gene set variation analysis (GSVA) showed that miR-223 affects apoptosis and inflammation-related pathways. Furthermore, differentially expressed (DE) genes were evaluated, and genes exhibiting contrasting expression trends in the miR-223 overexpressed and suppressed groups were assessed as potential target genes of miR-223. Potential target genes, including CDC25B, PTPRF, DCTN1, and DPP9, were observed to be associated with apoptosis and necroptosis. Finally, through integrative analysis of genome-wide association study (GWAS) data and the animal quantitative trait loci (QTL) database, we determined that target genes of miR-223 were significantly enriched in single-nucleotide polymorphisms (SNP) and QTLs related to somatic cell count (SCC) and mastitis. In summary, miR-223 has an inhibitory effect on S. aureus-induced cell apoptosis and necrosis by regulating PTPRF, DCTN1, and DPP9. These genes were significantly enriched in QTL regions associated with bovine mastitis resistance, underscoring their relevance in genetic regulation of disease resilience. Our findings provide critical genetic markers for enhancing mastitis resistance, particularly S. aureus-induced mastitis, through selective breeding. This work offers valuable insights for developing cattle with improved resistance to mastitis via targeted genetic selection.","PeriodicalId":14928,"journal":{"name":"Journal of Animal Science and Biotechnology","volume":"6 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding their adaptive traits can aid breeding programs target enhanced resilience and productivity, especially as we are facing important climate and agriculture challenges. To this aim the genomic architecture of 480 goats belonging to five breeds (i.e., Saanen [SAA], Camosciata delle Alpi [CAM], Murciano-Granadina [MUR], Maltese [MAL], Sarda [SAR]) reared in the Sardinia Island were genotyped and their genomic architecture evaluated to find molecular basis of adaptive traits. Inbreeding, runs of homozygosity (ROH) and runs of heterozygosity (ROHet) were identified. Finally, candidate genes in the ROH and ROHet regions were explored through a pathway analysis to assess their molecular role. In total, we detected 10,341 ROH in the SAA genome, 11,063 ROH in the CAM genome, 12,250 ROH in the MUR genome, 8,939 ROH in the MAL genome, and 18,441 ROH in the SAR genome. Moreover, we identified 4,087 ROHet for SAA, 3,360 for CAM, 2,927 for MUR, 3,701 for MAL, and 3,576 for SAR, with SAR having the highest heterozygosity coefficient. Interestingly, when computing the inbreeding coefficient using homozygous segment (FROH), SAA showed the lowest value while MAL the highest one, suggesting the need to improve selecting strategies to preserve genetic diversity within the population. Among the most significant candidate genes, we identified several ones linked to different physiological functions, such as milk production (e.g., DGAT1, B4GALT1), immunity (GABARAP, GPS2) and adaptation to environment (e.g., GJA3, GJB2 and GJB6). This study highlighted the genetic diversity within and among five goat breeds. The high levels of ROH identified in some breeds might indicate high levels of inbreeding and a lack in genetic variation, which might negatively impact the animal population. Conversely, high levels of ROHet might indicate regions of the genetic diversity, beneficial for breed health and resilience. Therefore, these findings could aid breeding programs in managing inbreeding and preserving genetic diversity.","PeriodicalId":14928,"journal":{"name":"Journal of Animal Science and Biotechnology","volume":"36 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the potential of the buccal (oral) microbiome as a diagnostic indicator for SARA, hypothesizing an interaction with the rumen microbiome. The study involved 47 dairy goats, including 11 on a control diet and 36 on high-concentrate diets with increasing rumen-degradable starch. Animals were grouped based on dietary exposure and ruminal pH: Control, Low-RDS Tolerance/SARA (LRDST/LRDSS), and High-RDS Tolerance/SARA (HRDST/HRDSS). Transcriptomics of rumen epithelium showed heightened inflammatory pathway gene expression in SARA-susceptible goats compared to controls and tolerant groups. Alpha diversity of ruminal bacteria showed lower Shannon diversity in HRDSS goats compared to HRDST whereas buccal bacteria displayed significantly lower Chao1 diversity in LRDSS goats compared to HRDST. Beta diversity analyses revealed distinct patterns between SARA-affected goats and healthy controls in both ruminal and buccal microbiomes. Prevotellaceae_UCG-003 emerged as a candidate biomarker, with reduced abundance in SARA-susceptible goats in both rumen and buccal samples. Machine learning classifiers achieved high accuracy in distinguishing SARA-susceptible goats using this genus (rumen AUC = 0.807; buccal AUC = 0.779). Source tracking analysis illustrated diminished cross-population of bacteria from the buccal to rumen (2.86% to 0.25%) and vice versa (8.59% to 1.17%), signifying compromised microbial interchange in SARA-affected goats. A microbiota transplant experiment verified SARA microbiota's ability to induce pH decline, escalate inflammation-related gene expression (MAPK10, IL17B, FOSB, SPP1), disrupt microbial transfer, and reduce Prevotellaceae_UCG-003 in recipients. Our findings highlight SARA’s dual impact on ruminal and buccal microbiota, exacerbating epithelial inflammation gene expression. Shifts in the buccal microbiome, specifically reductions in Prevotellaceae_UCG-003, mirror ruminal changes and can be influenced by inter-compartmental bacterial transmission, thereby offering a non-invasive diagnostic approach for SARA.","PeriodicalId":14928,"journal":{"name":"Journal of Animal Science and Biotechnology","volume":"52 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study determined effects of dietary supplementation of creatine (Cr) to gestating gilts on fetal development, the number and ratio of primary and secondary muscle fibers, and on protein expression in endometrium and fetal biceps-femoris muscle, respectively in fetal pigs on d 60 and d 90 of gestation. Reproductively mature gilts were synchronized to estrus using Matrix, observed for estrus (d 0), and artificially inseminated 12 h and 36 h later. Gilts were individually housed and fed 0.86 kg of 14% crude protein diet twice daily that meets nutritional requirements for pregnant gilts. Gilts were assigned to either basal diet control (CON) group, or Cr supplemented group (provided 30 g Cr monohydrate daily) from d 10 to either d 60 or d 90 of gestation. Gilts were euthanized and hysterectomized on either d 60 or d 90 of gestation. These protocols were completed in two replicates, as gilts were bred in spring and euthanized in summer or bred in fall and euthanized in winter (n = 20 gilts/replicate). Litter size, crown-rump length, sex, and fetal weight was recorded. Three female and male fetuses closest to mean litter weight were selected to assess effects of treatment on weight of fetal brain, kidney, liver, spleen, and biceps-femoris muscle. Data were analyzed to determine effects of treatment, days of gestation, replicate, and sex on litter size, fetal measurements, and incidence of intrauterine growth restriction. Dietary Cr supplementation increased fetal brain weight to body weight ratios on d 90 of gestation (P < 0.05) and fetal kidney weight to body weight ratios on d 60 of gestation (P < 0.01), while days of gestation had significant effect on expression of mitochondrial CK isoform in gilt endometria (P $$<$$ 0.05).

Nonetheless, its potential to mitigate coccidia infection in broilers remains uncertain. This study aimed to evaluate the impact of partially defatted BSFLM (pBSFLM) on growth performance, nutrient utilization, and intestinal health, focusing on morphology, immunology, and cecal fermentation in coccidia-infected broilers. Over the initial 13 d, 480 newly-hatched Cobb 500 male birds were allocated to three diets with increasing pBSFLM concentrations (0, 60, or 120 g/kg). At d 13 post hatching, chicks within each dietary group were further allotted to non-challenge or challenge subsets, generating six treatments in a 3 × 2 factorial arrangement. Challenged birds were orally administered oocysts of E. maxima, E. acervulina, and E. tenella (25,000:125,000:25,000). During the infection phase (d 13 to 19), linear interactions between Eimeria and pBSFLM were observed in gain to feed ratio (G:F) (P < 0.05) and cecal interferon-γ (IFN-γ, P < 0.05), with a tendency in cecal acetate concentration (P = 0.06). A quadratic interaction was observed in crypt depth (CD, P < 0.05). Incremental pBSFLM inclusion negatively affected G:F, CD, IFN-γ, and acetate productions in the ceca under coccidia challenge. Conversely in non-challenged birds, the impact of pBSFLM varied from neutral (e.g. G:F) to potentially advantageous (e.g. acetate). Challenged birds exhibited decreased (P < 0.01) BW, BW gain, feed intake (FI), and the apparent ileal digestibility and total tract nutrient utilization of DM, gross energy, and nitrogen (N). Eimeria challenge reduced (P < 0.01) serum carotenoid concentrations, decreased the villus height to crypt depth ratio (VH:CD, P < 0.01), and increased concentrations of branched-chain fatty acids, specifically isobutyrate (P = 0.059) and isovalerate (P < 0.05) in the cecum. Dietary pBSFLM addition linearly reduced (P < 0.05) BW, FI, and N utilization. Tendencies (P < 0.06) were observed where pBSFLM linearly decreased VH:CD and reduced goblet cell density. Increasing pBSFLM supplementation, particularly at 12%, adversely affected growth, ileal morphology, cecal acetate production, and downregulated key cytokine expression in response to coccidia infection.","PeriodicalId":14928,"journal":{"name":"Journal of Animal Science and Biotechnology","volume":"15 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several systems coordinately regulate redox balance, including the mitochondrial respiratory chain, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, and different antioxidants. However, it remains unclear which redox balance compartments in the intestine are crucial for determining FE. In this study, we first screened the key targets of different metabolites and redox balance-related gene expression in broiler ceca. We then constructed a mouse colitis model to explore malic acid (MA) ability to alleviate intestinal inflammation. We further used controlled release technology to coat MA and investigated its effects on the intestinal redox status and FE in vivo. Finally, we examined the underlying mechanism by which MA modulated redox status using a porcine intestinal epithelial cell jejunum 2 (IPEC-J2) cell model in vitro. Our results demonstrated that the MA/malic enzyme 3 (ME3) pathway may play an important role in reducing oxidative stress in the broiler cecum. In addition, colon infusion of MA attenuated inflammatory phenotypes in the dextran sulfate sodium salt (DSS) induced mouse colitis model. Then, dietary supplementation with controlled-release MA pellet (MAP) reduced the feed to gain (F/G) ratio and promoted chicken growth, with reduced oxidative stress and increased bacterial diversity. Finally, the in vitro IPEC-J2 cell model revealed that ME3 mediated the effect of MA on cellular oxidative stress. In summary, our study firstly revealed the important role of the MA/ME3 system in the hindgut of broiler chickens for improving intestinal health and FE, which may also be crucial for the implications of colon inflammation associated diseases.","PeriodicalId":14928,"journal":{"name":"Journal of Animal Science and Biotechnology","volume":"30 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the effects of SeY and SeL on egg quality, antioxidant capacity, Se deposition, and gut health in laying hens. After a two-week pre-treatment with a Se-deficient diet (SeD), 450 Hy-Line Brown laying hens (30-week-old) were assigned into five dietary groups with six replicates of 15 hens each. The groups included a SeD, SeD supplemented with 1.5 mg Se/kg from SeY (SeY15), or 1.5, 3.0, and 6.0 mg Se/kg from SeL (SeL15, SeL30, SeL60). The feeding trial lasted for 12 weeks. SeY15 and SeL15 improved the feed-to-egg ratio (P < 0.05) in the latter stages. Haugh units were significantly increased (P < 0.05) in the SeY15 and SeL30 groups, while darker yolk color (P < 0.05) was observed in the SeY15, SeL15, and SeL60 groups. All Se-supplemented diets increased Se content in whole eggs, albumen, and yolk (P < 0.05), while SeL groups showed a dose-dependent effect. Antioxidant enzyme activities increased, and MDA content decreased in the serum (P < 0.05), with SeY15 showing the highest GSH-Px levels (P < 0.05). SeL60 increased serum alkaline phosphatase and aspartate transaminase, and distorted the liver architecture (P < 0.05).

Assessment of cryopreserved sperm, with or without prior treatment with ferroptosis or apoptosis inhibitors, demonstrated the significant efficacy of ferroptosis inhibitors in reducing freezing damage. This implicates ferroptosis as the primary form of regulated cell death induced during sperm cryopreservation. Additionally, the positive rate of transferrin receptor protein 1 was significantly lower in fresh live sperm (47.8%) than in thawed live sperm (71.5%), and the latter rate was lower than that in dead sperm (82.5%). By contrast, cleaved caspase-3 positivity showed no significant difference between fresh live sperm and thawed live sperm but was notably lower in thawed live sperm than in dead sperm.
