A study was conducted to determine the effect of feeding dry carboxylate salt mixture of fish oil (DCM-FO) on fatty acids composition of cow milk fat. Eight lactating Friesian Holstein crossbred cows with an average weight of 275 to 300 kg produced 3 to 3.5 liters milk per day, were randomly allocated to two treatment groups. All cows were fed approximately 4 kg of concentrate and maize husk, each weight 2 kg. Two treatment groups were given no supplement and 90 g of DCM-FO as a supplement, respectively. Result of the study showed that supplementing DCM-FO in lactating cows feed significantly increased milk fat, caprylic acid (C8:0), capric acid (C10:0), myristic acid (C14:0), EPA (C20:5n-3), and DHA (C22:6n-3). Inversely, 90 g DCM-FO supplementation in dietary can significantly decrease oleic acid (C18:1). Supplementing 90 g DCM-FO in dietary had no significant effect on lauric acid (C12:0), palmitic acid (C16:0), stearic acid (C18:0), linoleic acid (C18:2), and linolenic acid (C18:3). The study indicated that supplementing 90 g of DCM-FO in lactating cows feed did not enhance long-chain fatty acids except for EPA and DHA in cow milk. However, it increased milk fat and short-chain fatty acids in cow milk fat.
