It doesn't look like ragwort to me, but I can't work out what it is either, so I'm unwilling to say I'm certain. Ragwort cut at haymaking time normally has a woody stem that supports the flowers. The typical ragwort leaves attached to that woody stem are what I would look for, other non-toxic plants can have similar daisy-like flowers.
Is this dried ragwort in my haylage? Can’t decide. Appreciate any thoughts x
Looks like cow parsley to me.
