it could help if you had a female that she could cycle with i know when i used to breed show hogs ( and dont know if its the same) but if you brought a new hog that didnt cycle into a group that had a regular cycle it would get that hog to cycle with the group... again dont know if its the same.
just my 2 cents.
i breed apbt and it helps alot with other females around the estrogen stimulates it and causes others to go in
