Something left hundreds of hoof prints in my dad's back yard. He thinks it was 5 critters. It's a relatively wet site and the prints are up to 4" deep. Deer usually don't leave a track and they have plenty of experience with deer. I don't want to give the location so that it doesn't distract the options but it is in the midwest USA.
Most common large herbivores in the region are deer and cows.
But there is a precedent:
“In that case,” said Holmes, rising, “I think that my friend and I can congratulate ourselves upon several most happy results from our little visit to the North. There is one other small point upon which I desire some light. This fellow Hayes had shod his horses with shoes which counterfeited the tracks of cows. Was it from Mr. Wilder that he learned so extraordinary a device?”
The Duke stood in thought for a moment, with a look of intense surprise on his face. Then he opened a door and showed us into a large room furnished as a museum. He led the way to a glass case in a corner, and pointed to the inscription.
“These shoes,” it ran, “were dug up in the moat of Holdernesse Hall. They are for the use of horses; but they are shaped below with a cloven foot of iron, so as to throw pursuers off the track. They are supposed to have belonged to some of the marauding Barons of Holdernesse in the Middle Ages.”

He measured them at approximately 3.5" long and 4" wide. Our current guess is cows but it's pretty rare to have loose cows in this area. But more likely than a moose, elk or ibex. No rooting or browsing, they just passed through the back yard.
Speaking of the silly hour, I once came home from work to find a car driving very slowly down our gravel road (public) in front of our house. When I pulled into our driveway from behind the car, it hit the brakes and a guy got out inquiring about the massive hoof prints on the road, thinking it would be his prize buck the coming fall hunting season!

Turns out, my wife had been walking a large Hampshire hog back to the property on that road....and the tracks had him pretty hopped up! LOL

Might be worth doing a "Google Earth" look a your neighbors - might show WHO has hoofed livestock...and then maybe a phone call to see if they know they are going "walk-about"!
