This study investigates the effects of substituting 30%, 60% and 100% sunflower meal concentrate mixture with flaxseed meal on milk production and chemical composition, with special emphasis on lipid profile and fatty acid content. The research was conducted over a 30-day period on a herd of 28 Romanian Black Spotted dairy cows, divided into four groups (one control group and three experimental groups). Milk samples were analyzed in an accredited laboratory to determine dry matter, protein, lipid and fatty acid content. The results showed that flaxseed meal supplementation did not negatively affect total lipid or saturated fatty acid content, but significantly increased omega-3 fatty acids and reduced trans and omega-6 fatty acids, thus improving the nutritional quality of the milk. These findings support existing research and highlight the potential of flaxseed cake as a functional ingredient that enhances milk quality for health-conscious consumers. The study opens important perspectives for integrating this nutritional strategy into modern dairy cow farming practices.
