Abstract

Cis-9, trans-11 conjugated linoleic acid (CLA) is the most common type of CLA found in milk. It has gained a lot of attention because it may have several health benefits. This bioactive lipid is primarily derived from ruminal biohydrogenation of dietary linoleic acid and endogenous synthesis in the mammary gland via Δ9-desaturase activity. Various dietary and management strategies influence CLA concentrations in milk, including forage composition, lipid supplementation, and grazing practices. CLA-enriched dairy products offer promising nutritional advantages, including potential roles in lipid metabolism, body composition modulation, and immune function enhancement. Research suggests that cis-9, trans-11 CLA may exert anti-inflammatory, anti-carcinogenic, and cardioprotective effects, though the underlying mechanisms require further elucidation. Bioavailability and dose-dependent responses in human health remain key areas of investigation. Moreover, processing methods and storage conditions impact CLA stability in dairy products, necessitating optimized production techniques. Future research should focus on precision feeding strategies to enhance CLA biosynthesis while ensuring sustainability in dairy production. Integrative approaches utilizing genomics, metabolomics, and microbiome analysis may offer deeper insights into regulatory mechanisms governing CLA metabolism. Assessing consumer perceptions and market potential for CLA-enriched dairy products will be crucial for industry applications. Advancing knowledge on CLA’s multifaceted health effects and optimizing its dietary intake may contribute to improving both public health and dairy sustainability.

Keywords: Lipid metabolism, milk fatty acids, ruminal biohydrogenation, sustainable dairy, trans fatty acids
