Red clover and high proportion of forage in dairy cow diet increases the concentration of bioactive substances in milk, e.g. unsaturated fatty acids and antioxidants. In the present experiment twenty-four Swedish Red dairy cows were fed three silages in a Latin Square design to study the effect of silage botanical composition and harvest time on milk fatty acid, α-tocopherol and β-carotene concentration. The silages were red clover/grass silage (mixture of first and second cut), red clover/grass silage (mixture of first, second and third cut) and birdsfoot trefoil/grass silage (mixture of first and second cut). Botanical composition and harvest system affected silage vitamin and fatty acid concentration with higher concentrations of α-linolenic acid, α-tocopherol and β-carotene in red clover/grass silage (mixture of three harvests). Milk linoleic and α-linolenic acid concentration was higher with the two red clover diets but α-tocopherol, β-carotene and retinol concentration was not affected.
