Wrongo. What some ranchers overlook is that they are not selling beef. They are selling grass. They just ship it to market in a beef container. And how efficiently a bovine converts grass to beef is very important. So the question isn’t how many head of cattle you put on any given pasture, it’s how many pounds you put on that pasture and how many pounds you have at market time.
I submit that if you put the same number of pounds of Longhorns on a given pasture they will return the same amount, or more, beef as their bigger cousins. They graze more efficiently because nature taught them to survive on marginal forage. They are more heat tolerant so they will continue to graze through many a hot day. You drive through cattle country when the thermometer is topping eighty degrees and you’ll see cattle resting under shade trees or on the shady side of buildings and down in shady draws. They’ll stay there until it cools off. But not Longhorns. They’ll be on their feet, grazing the grass or browsing the brush. Oh, and by the way, most Herefords and Angus don’t browse. They’re too persnickety. They only use the brush for shade.
Longhorns also handle going without water better than most other breeds.
