Well, it can be a big deal - many places do not
allow burial of this size carcass - or any carcass for that
matter.
I was just at the National Stud in the UK and they told
us you can't bury any type of livestock on the island there any
more.
If carcass removal is such a big deal (as so many say), then as a group
(horse people) we need to come up with a solution rather than using slaughter
as an acceptable option. Here at our ranch, we compost.
