Abstract

In a previous trial we have demonstrated the increased content of fatty acids CLA and DHA in milk following to the administration of a functional feed NATW3(WBC 2008, Budapest). This study is to demonstrate that lower quantity of NATW3 in feed (320 g/subj./day vs 600 g/subj./day) resolves in similar results: decrease in SFA and increase in PUFA, especially cis-9 18:1, CLA and DHA. Trend of metabolic parameters was confirmed, expecially for lipidic status. The trial involved 116 high-producing dairy cows belonging to two livestocks fed with the same feed: grass family hay (especially oat hay), grass family hay silage (triticale and barley), and industrial feed. The difference concerned the way of administration of industrial feed, ad libitum and with automatic feeding system. Milk was utilized for cheesemaking. Analysis of lipid fractions stressed variations in composition , especially pointed out the transfer of PUFA in different cheeses, making their composition more suitable for a more salutistic intake. “Mozzarella": total lipids +0,96%, total proteins +1,22%, CLA (C18: 2) +118,67%, DHA (C22: 6) +27%, EPA (C20: 5) +60,00%, palmitoleic acid (C16: 1) +29,15%, decrease of stearic acid(C18: 0) --9,84%. ”Canestrato": total lipidis +0,46%, total proteins +0,66%, CLA (C18: 2) +160,42%, DHA (C22: 6) + 80,00%, EPA (C20: 5) +154,54%, palmitoleic acid (C16: 1) +39,00%, decrease of stearic acid (C18: 0) -12,73%. ”Caciocavallo": total lipids +2,48%, total proteins +0,33%, CLA (C18: 2) +58,28%, DHA (C22: 6) + 55,00%, EPA (C20: 5) +76,67%, palmitoleic acid (C16: 1) +40,12%, decrease of stearic acid (C18: 0) -11,92%.
