The study investigated the effects of dietary supplementation with extruded linseed and oregano on goat milk quality and the characteristics of meat from suckling kids. The results showed that the linseed diet lowered saturated fatty acid content in meat and increased monounsaturated and polyunsaturated fatty acids. Addition of oregano improved meat quality and shelf-life.
Extruded linseed (Linum usitatissimum) in ruminant diets has been investigated as a strategy to improve the nutritional value and healthiness of meat fat; however, increased polyunsaturated fatty acids may limit the shelf-life of meat. Oregano (Origanum vulgare) has a documented antioxidant activity. The aim of the study was to investigate the effects of dietary supplementation with extruded linseed and oregano on goat milk quality and whether the characteristics of goat milk affect the physical and chemical features, fatty acid profile, meat lipid oxidation, and sensory properties of meat from suckling kids. Thirty-six male kids were weaned and divided into three homogeneous groups (n = 12); each group was either fed a control diet (C), or a diet containing 3% extruded linseed with or without the addition of 0.6% oregano (L + O and L, respectively). The diets containing linseed lowered (p < 0.05) the saturated fatty acid content in meat, and increased (p < 0.05) monounsaturated and polyunsaturated fatty acids and conjugated linoleic acid. Oregano addition to the linseed diet proved to be effective in preserving meat shelf-life, as shown by a significant (p < 0.01) reduction in the malondialdehyde concentration after 10 days of storage, and improved meat succulence, tenderness, juiciness, and overall acceptance.
