The seed of this weed is polymorphic and one of the polymorphs can stay dormant for months. It has a hard coat and my experiment is to find out if this seed is viable after passage through goats.

No, I have not. Sorry.
Are you thinking to try something to break dormancy? There are several methods. Maybe It will be interesting. I'd like suggest to you look at ISTA Rules.

Thank you for the information. I was investigating the possibility of feral goats disseminating the seeds and it turns out the likelihood is quite high given the results form other studies on R.obtusifolius and in Newzealand.

Harrington et al. (2011) has reported the survival of 32.3% seeds of broad-leaved dock (Rumex obtusifolius) when passed through the goat's gut.
