A trial was carried out at the University of Tehran, Iran, to assess the efficacy of Optomega, a source of EPA and DHA, on dairy cow mammary gland development and milk production. 10 multiparous Holstein dairy cows were randomly allocated to one of the two treatments (palm oil, or fish oil supplied as Optomega) beginning 42 days prior to expected calving date, until 63 days in milk. Milk fatty acids content was determined on days 7 and 63 of lactation as well as samples of mammary tissue taken by a biopsy gun. Milk yield was measured daily and milk quality was considered weekly.

Including Optomega in dairy rations in the place of palm oil:
Therefore, including Optomega in the diet of dairy cows both pre- and post-calving can help increase milk yield.
