I \u00f8kologisk produksjon er det viktig \u00e5 finne alternativ til syntetiske vitamin, som E vitamin (tokoferol). I syntestisk E vitamin har 87,5 % av molekylene ein ikkje-naturleg konfigurasjon og er lite effektiv biologisk. Det er s\u00e5leis viktig for den \u00f8kologiske gardbrukaren \u00e5 finne naturlege vitamin- og antoksidantkjelder som er enkle \u00e5 handtere. I det oms\u00f8kte prosjektet skal ulike tang- og tareartar granskast for innhald av alfa-tokoferol og deira antioksidative aktivitet for \u00e5 finne moglege nye f\u00f4rtilskot. I eit fors\u00f8k med mj\u00f8lkeku, skal effekten av tilskot av tangmj\u00f8l og naturleg E vitamin p\u00e5 innhald av alfa-tokoferol i mj\u00f8lka og den oksidative stabiliteten hos fersk mj\u00f8lk og r\u00f8mme granskast. I eit anna fors\u00f8k skal effekten av dei same fors\u00f8ksfaktorane, tilskot av tangmj\u00f8l og naturleg E vitamin, p\u00e5 immunologi og bakteriefloraen i mage og tarm hos sau og lamma deira testast.

      "abstract": "Main objective: Replace synthetic antioxidants (vitamins) with natural sources in feed supplements \r\nSub goals:\r\n1.Investigate Northern macroalgae sources: species, alfa-tocopherol content and anti-oxidative activity \r\n2.Evaluate the effects of antioxidants from natural vitamin supplements on the oxidative stability of dairy cow milk and milk products \r\n3.Evaluate the effects of antioxidants from natural vitamin supplements on the gastrointestinal microbiota and the immunology in ruminants \r\n\r\nFat-soluble vitamins, like vitamin E, are important for ruminants in respect to maintain an optimal immune function, reproduction traits and a high quality of milk and meat. In organic production it is important to find alternatives to synthetic vitamins, as vitamin E (tocopherol). Synthetic vitamin E consists of 87.5 % tocopherol molecules with a non-natural configuration and biological ineffective. Thus, the possibility for supplying with natural vitamins or antioxidants easy to handle will be of great importance for organic farmers. In the present project we will screen seaweed species for their content of alfa-tocopherol and their anti-oxidative activity in order to find potential new natural feed additive sources. The effects of seaweed meal and natural vitamin E supplement on the dairy cow milk content of alpha-tocopherol, oxidative stability of milk and sour/cultured cream, and immunology and gastrointestinal micro biota in sheep and their off-springs will be tested experimentally in two feeding experiments with dairy cow\r\nand sheep, respectively.",
