ANDI MURLINA TASSE. Fatty Acids Profile in Milk Cow’s fed Containing Mixed Dry Carboxylate Salt or Methyl Ester. Advisor: JAJAT JACHJA, LATIFAH K.DARUSMAN, and MUHAMMAD WINUGROHO. Dry carboxylate salt mixed (DCM) and dry methyl ester mixed (DMM) are product of fish oil processing. It’s a source of essential fatty acid as EPA (eicosapentaenoic acid, C20:5(n-3)) and DHA(docosahexaenoic acid, C22:6(n-3)) for lactating dairy cows. The aim of experiments were to evaluate: (1) the effect of the concentrate with DCM or DMM in ruminal fermentation, (2) the effect of the dietary with DCM or DMM on the profile of fatty acids in cows milk, and (3) the mechanism of incorporation fatty acids in cows milk . The ruminal fermentation experiment used concentrate’s 14% crude protein, and 64% total digestible nutrient with 0, 15, 30, 45, dan 60 g kg DCM or DMM. The result of experiment showed concentrate with in consentrate with with 0, 15, 30, 45, dan 60 g kg DCM or DMM can be used to the ruminant dietary. The effect of offered of dietary with DCM or DM on fatty acids profile in cows milk, and mechanism of incorporation of fatty acids experiment used concentrate with 45 gkg DCM (DCM given at 1% of kg DM of dietary) or 45 gkg DMM (DMM given at 1% of kg DM of dietary). The treatments were allotted in nine lactating dairy cows in mid lactation, and body weight 320-350 kg and daily milk yield 8-10 Ld
