Below, I have included Susan's comments on flax
seed which I have saved from the archives. I don't recall how long
ago Susan wrote this. I don't know if this is the advice she would
give today. But it may help address the current comments on
RC.
"My suggestion is to start horses out with
about a half cup of flax seed twice a day and gradually (over several
weeks) work it up to about 2 cups or so twice a day. If you grind it
ahead of time, it needs to be fed semi-immediately (ie, that feeding) or
stored in an airtight container in the frig or freezer, or the fatty acids
you want will oxidize very quickly.
Personally, I
don't grind or otherwise process the seeds at all, and still saw a good
response in my animals, but to each his own. Grinding certainly
improves availability of the oil content, but IMO it's not absolutely
critical.
I do like feeding the seeds mixed in
some sort of wet or sticky mash, as the seeds themselves are pretty light
and easily aspirated."
