I wouldn't know since I never do it.
Sure, if you gut the animal and in a short time hang it and cut its throat, it will bleed, but it wasn't necessary.
90% of its blood will be lost by the time you finish gutting it.

For that matter, when you butcher your deer (I do my own) it will continue to bleed. You can quarter it up and put it on ice and for the next day or two it will continue to bleed.
Point is, cutting its throat is NOT needed. It doesn't accomplish anything.
Hey, if you want to do it, go for it.
