Lifestock killings

Could someone please tell me where I could get hairs tested that were found
on a barbwire fence after several slaughtering of goats and sheep. So I
could at least find out whats been slaughtering livestock on different farms
only days apart from one farm to the next.These poor farmers are puzzled and
have no idea what kind of creature is doing this. One farmer lost15 out of
his16 goats and then the next day after the slaughtering of his goats then
something turned around and slaughtered 9 of his roosters.Thanks Cynthia
