I have found that dead cows and such don't last very long if left on a good dry piece of ground away from the road and house. We have quite a population of coyotes around here that will strip a carcass down in short order. Not much left in a weeks time.
Around here the feral hogs eat carcasses.
Hogs eat hogs. Have trail cam proof. Sorta lost my appetite for woods killed hogs.
Nasty cannibals. And some wonder why I don’t eat’em. Glad to shoot’em.
Over the years around here, it seems coyotes won't dine on a cow if there were any shots or treatment efforts to save the critter. Only start eating if conditions and temps get really tough. Let a cow just tip over and die on her own, and she's gone in about 3 days.
What is she eating? Usually when you find one dead out of the blue on our ranch 90+ % of the time it happens it's a poison weed of some sort, or feed (corn stalks, sorghum, etc...) extremely high in nitrates.
When we had the cattle trucks we hauled a lot of retired dairy cattle to Beef Packers in Fresno,Ca. Every once in awhile we’d get a dead one and would haul it over to the rendering plant on the way out of town...... More than once you would see a couple wetbacks sitting on a bloated up cow with their lunch boxes enjoying a burrito and a soda lol.
