While intensive breeding and advancements in nutrition and management practices have driven significant improvements in meat production, sustainable solutions are still needed to further enhance both meat yield and quality. The <em>Myostatin</em> (<strong><em>MSTN</em></strong>) gene, which acts as an inhibitor of muscle growth and differentiation, has been extensively studied. Suppressing <em>MSTN</em> activity has been shown to induce muscle hyperplasia and/or hypertrophy in various animal species, resulting in increased skeletal muscle mass. However, <em>MSTN</em> deficiency also decreases fat mass, which can negatively impact meat flavor and quality. In addition to genetic regulation, the gut microbiome plays a crucial role in muscle development and fat accumulation. Emerging evidence suggests a complex interplay between the gut microbiota and the host, which may influence meat production and quality. Interestingly, <em>MSTN</em>-modified animals may exhibit altered gut microbiota, indicating the potential to manipulate gut microbiota to increase meat quality. Thus, integrating these insights is crucial to satisfy the growing consumer demand for high-quality meat while ensuring sustainable production practices. This review aims to provide a comprehensive overview of the effect of <em>MSTN</em> on muscle mass and fat accumulation, as well as the opportunities and challenges associated with using gene editing in farm animals to enhance meat quantity. Moreover, it emphasizes the importance of the gut microbiota in modulating muscle growth and fat deposition, highlighting the potential for gut microbiota manipulation to improve meat quality.</div></div>","PeriodicalId":389,"journal":{"name":"Meat Science","volume":"231 ","pages":"Article 109950"},"PeriodicalIF":6.1,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027655","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}

However, its chemical composition and sensory attributes vary significantly owing to genetic, management, and environmental factors. This study conducted a systematic review and a meta-analysis to quantify the nutritional and sensory properties of camel meat and identify the key factors influencing these characteristics. A systematic review of peer-reviewed studies was conducted using Springer, PubMed/MEDLINE, Scopus, and ScienceDirect databases. This review comprised 57 papers published in English from 12 countries, covering the period between January 1991 and August 2024, including 377 analyses focusing on camel species, breeds, and breeding systems. Statistical analyses were performed to determine the effect sizes, heterogeneity, and impact of the moderating factors. The findings from our meta-regression and subgroup analyses revealed that variations in camel meat profiles are influenced by multiple factors, including breeding system, camel species, breeds, and age, but not by sex. Subgroup analysis revealed that higher final body weight (FBW) was reported for meat from <em>Camelus bactrianus</em> camels raised under the extensive system. Camels slaughtered at ≤6 years of age were characterized by higher dry matter, ash, and fat contents, but lower sarcomere length, lightness, redness, and cobalt content. The Najdi, Baladi Saudi, and Pakistani breeds were characterized as tender meat breeds. This study emphasizes the need for improved breeding strategies, meat processing techniques, and market awareness to enhance the appeal of camel meat. These findings provide valuable insights for livestock producers, policymakers, and the food industry, supporting the promotion of camel meat as a viable substitute for traditional red meat in regions affected by climate change and food insecurity.</div></div>","PeriodicalId":389,"journal":{"name":"Meat Science","volume":"231 ","pages":"Article 109947"},"PeriodicalIF":6.1,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145079245","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}
