Sorry but I am not competent to answer rhis question

HH

See my paper on the contribution of milk fat to the daily intake of EPA and other omega-3 fatty acids by humans. For EPA it is between 10-15%

Dear colleagues,

Thanks for your contributions. The question is: cows fed linseed produce milk with higher  C18:3n3 but with really small increases in its typical content of Oemga-3  (because cows scarcely convert C18:3n3 into either DHA or EPA). Then, this is not useful for improving human health as humans cannot utilize C18:3n3 as a useful source of Omega-3, as we need EPA and DHA and we cannot convert C18:3n3 into EPA and DHA.

What are your views in this regard?

Dear Alfredo

Milk fat contributes between 10-15% to daily intake of EPA and that is significant. Humans can convert C18:3n-3 into EPA and other C20 and C22 omega-3 fatty acids by the omega-3 pathway. Mammals that are not able to do that are cats etc.

Greetings

It is not a good idea to use soya for improvement of milk fat quality. I will soon submit a paper on this topic

Yes. Actually you should check a company called Valorex in France. They have published data showing exactly what you are looking for.

Dear Pierre

Where are the data of Valorex published?

Few years back I was involve was extruded linseed I read the trial summary but did not kept a copy of the original paper.

I would contact the company for more information

Dear Hein,

Did you attend the last EAAP meeting? Dr. Bauman (if I am not wrong) highlighted this almost lack of capability  by both humans and cows to convert C18:3n3 into DHA and EPA. Maybe we are facing either different data or conclusions. I will search for the talk and share it here. Interesting discussion.

I am not sure
