The biggest feedlot in the world depends on how you count. By corporate network, Five Rivers Cattle Feeding is the largest cattle feeding operation on the planet, with a one-time capacity of more than 900,000 head across 13 feedyards in six U.S. states.1JBS USA Sustainability. Five Rivers Cattle Feeding By single site, Australia’s Grassdale feedlot near Dalby, Queensland, holds roughly 79,000 head and ranks among the largest individual operations anywhere, though several privately held U.S. yards in the Texas Panhandle and western Kansas are believed to operate at similar or larger scales without publishing exact numbers.
Five Rivers Cattle Feeding: The Largest Network
If the question is total cattle under one company’s management, Five Rivers wins by a wide margin. The company runs 13 feedyards across Colorado, Kansas, Oklahoma, Texas, Arizona, and Idaho, with a combined one-time capacity of more than 865,000 head.2Five Rivers Cattle Feeding, LLC. Locations Cattle cycle through those yards roughly twice a year, and Five Rivers markets more than 1.8 million head annually.
The parent company, JBS, reports the network’s one-time capacity at over 900,000 head, a figure that likely reflects ongoing expansions and the timing of each count.1JBS USA Sustainability. Five Rivers Cattle Feeding JBS also runs feeding facilities outside the Five Rivers brand, alongside processing plants that handle cattle from arrival through boxed beef. One example of a confirmed capacity within the Five Rivers network is Coronado Feeders near Dalhart, Texas, at 65,000 head.3Five Rivers Cattle Feeding, LLC. Coronado Feeders
Grassdale: The Largest Confirmed Single Site
Grassdale, owned by Mort & Co, sits in Queensland’s Darling Downs region and operates at a capacity of about 79,000 head. That makes it the largest feedlot in Australia and one of the largest single-site operations anywhere.4ABC News. Mort and Co Australias Largest Private Cattle Feeder for Sale After 29 Years Earlier reporting pegged the capacity at 77,000 head following a major expansion.5Grain Central.

Mort & Co had signaled plans to push its total feeding capacity to around 130,000 head through additional development, which would have rivaled JBS Australia as the nation’s largest lotfeeder.5Grain Central.

Real estate analysts estimated Grassdale alone could sell for up to $200 million, with the roughly 80,000-head herd potentially adding another $210 million at prevailing cattle prices.4ABC News.

Why the Single-Site Ranking Is Hard to Pin Down
Naming the single largest U.S. feedlot with confidence is harder than it sounds. Many of the largest yards are privately held and don’t publish exact capacities. Several individual yards in the Texas Panhandle and western Kansas are believed to hold 75,000 to 90,000 or more head at a time, and Bar-G Feedyard near Hereford, Texas, is widely cited among that group, but exact figures from those operations are difficult to verify independently.
What’s clear is that the U.S. dominates global feedlot scale. Australia has Grassdale and a handful of other large operations, Brazil runs sizeable cattle operations, but the sheer number of 50,000-plus-head yards packed into a tight geographic band across the American plains has no equivalent anywhere else.
Where the Mega-Feedlots Cluster
Big feedlots don’t appear randomly on a map. They cluster where three things converge: cheap grain, flat open land, and proximity to large packing plants. In the United States, that formula points to the Texas Panhandle, southwestern Kansas, and western Nebraska. The corridor sits on or beside the country’s largest corn and grain sorghum production areas, which keeps feed transport costs manageable. Major packing plants run by JBS, Tyson, Cargill, and National Beef are positioned nearby, minimizing the distance cattle travel from feedlot to processing.
The Darling Downs region of Queensland fills a similar role in Australia. Grassdale and several other large feedlots operate there because the climate supports year-round finishing and the area has rail and road connections to export-oriented processing facilities on the coast. Both regions are semi-arid, both sit atop significant grain production zones, and both built their feedlot industries in close coordination with nearby meatpacking capacity. Shared labor pools, specialized veterinary services, and feed-milling infrastructure create efficiencies that isolated operations can’t match.
What Running a 70,000-Head Yard Actually Involves
A feedlot holding 70,000 or more cattle is essentially a small city dedicated to one purpose: putting weight on animals as efficiently as possible. A finishing steer typically eats 25 to 30 pounds of feed per day, so a 75,000-head yard burns through roughly 1,000 tons of feed daily. Central feed mills on these properties rival commercial grain processing plants in scale, mixing rations of corn, silage, protein supplements, and minerals around the clock.
Water demand is equally intense. During summer months, a heavy steer nearing finish weight can drink more than 20 gallons per day. Across tens of thousands of head, that means well over a million gallons consumed daily at a large facility. Underground piping networks deliver water to troughs along miles of concrete feed bunks, and most operations maintain backup generators and redundant pumping capacity because even a few hours without water in midsummer heat can trigger health emergencies and animal losses.
Then there’s waste. Tens of thousands of cattle produce thousands of tons of manure daily, which must be collected, stored, and managed to prevent contamination of nearby waterways and groundwater. Large-scale lagoon systems and composting operations handle the volume, and each represents a significant capital investment. Some operators, including Mort & Co at Grassdale, have turned manure processing into a separate revenue stream through granulation businesses.
Water sourcing adds a long-term constraint on U.S. operations in particular. Many of the largest yards draw from the Ogallala Aquifer, which underlies much of the Central Plains and has been declining for decades. States in the region administer their own water rights systems, and large feedlots must obtain extraction permits that specify how much water they can pull annually. Permitting frameworks vary from state to state, but the trend across the region has been toward tighter allocation and more rigorous monitoring as aquifer levels drop.
