Roque Quagliato, Brazil's 'King of Cattle,' and the Fight Over Amazon Beef

Who Is Roque Quagliato?

Roque Quagliato is a Brazilian rancher known in the press as the Rei do Gado, or King of Cattle. He runs cattle operations in the state of Pará, in the Brazilian Amazon, under the Grupo Rio Vermelho and Quagliato names. When Reuters profiled him in June 2025 he was 85. It reported that decades of ranching in the Amazon had brought him great wealth and some legal trouble.

This profile is cautious about numbers on purpose. Quagliato himself did not give Reuters his herd size, and the published figures vary widely, so every number below is attributed.

How Big Is Quagliato's Herd?

Brazilian rural outlets such as Compre Rural have reported that the group had grown to about 240,000 head of beef cattle on roughly 112,000 hectares in Pará after a land purchase in 2023, a figure that traces to a Folha CG report. One of those headlines on the rei do gado herd growth story gives the larger number.

Reuters reached a different picture. In its June 2025 piece, republished by outlets including AOL, Quagliato declined to say how many animals he owns, and the news agency noted that local publications estimate about 150,000 head. Because sources differ by roughly 90,000 animals, the safest reading is that this is one of the largest private herds in the Amazon, with no audited number in public view.

Ranching in the Amazon

Quagliato's career belongs to the cattle frontier of Pará, where ranching has expanded across forest country. Brazilian trade coverage describes him as arriving in a region where there was almost nothing and building an operation over about five decades, a framing that comes from the headline of a Compre Rural feature rather than from a documented biography.

What can be said from the Reuters reporting is that his family's large farms have been in the center of Amazon ranching debates. Reuters says they were accused of subjecting workers to slavery-like conditions in the 1990s and of clearing large areas of rainforest in the early 2000s.

Controversies and Legal Record

Reuters reports that Brazil's federal environmental agency says Quagliato paid all his deforestation fines except one, which he settled by agreeing to regenerate the forest. It also reports that a family member was recently convicted of submitting workers to slave-like labor conditions and is appealing the verdict. Quagliato declined to comment on those cases.

These points are stated as reported, not as findings of this site. They matter for anyone assessing his place among cattle barons, because modern beef buyers in the United States, Europe and Asia increasingly ask where an animal was raised and whether the land was cleared.

Cattle Tracing in Pará

The most recent chapter is traceability. Reuters reports that his cattle were the first to receive ear chips under Pará's government program, which aims to make millions of animals traceable. He told the reporter that ranchers who talk it over conclude that they have to do it, while acknowledging a cost. He declined to say how many of his animals have been tagged.

The program is covered further by ESM Magazine, which reprinted the story under the headline about the King of Cattle and a plan to save the Amazon.

Why Quagliato Matters to Beef

A rancher with one of the biggest herds in Pará carries influence over how the state's cattle are bought, tagged and sold. If a producer of this size accepts tracing, smaller neighbors find it harder to refuse. For anyone comparing cattle barons across continents, he is the clearest example of the new test: size is no longer enough without proof of where the cattle came from.
