A sourced map of animal agriculture

The Factory Farm System

From "the animal is born" to "meat is on your plate": the inputs that feed it, the losses along the way, the companies that run it, the money that moves, and the people working to limit it. Every number here carries a citation. The goal is a deeper understanding of what goes into animal agriculture, honestly.

Attrition

Of 1,000 hatched, how many are eaten?

A chicken-based walk down the funnel. Watch the caveat: the biggest leak is not on the farm, it is on the plate. Each stage uses a different denominator, so hover the labels for the honest footnotes.

Bars are illustrative counts per 1,000 birds. On-farm mortality, condemnation and DOA are shares of birds; retail and plate losses are shares of the food supply by weight, so they cannot be added as if they were the same 1,000 birds. Tap any label for the caveat.

Precarious parts

Where the system is brittle

Concentrated, tightly coupled systems fail together. These are the pressure points where one shock ripples across the whole chain.

Fertilizer & natural gas

Nitrogen fertilizer is 75-90% natural gas by cost; farmer-paid ammonia nearly quadrupled from ~$487 to ~$1,500/ton (2020-2022).218

War in Ukraine

Russia supplies ~23% of global ammonia exports; the fertilizer price index hit an all-time high of 1,270 in March 2022.2322

Ethanol mandates

Nearly 45% of US corn goes to ethanol, tying feed-corn prices to fuel policy.1726

Genetics duopoly

Two firms (Aviagen, Cobb) hold 70-90% of broiler genetics worldwide: a single narrow gene pool for the world's most-eaten meat.25

Avian influenza

H5N1 has killed roughly 188 million US birds since Feb 2022, and spilled into 800+ dairy herds in 2024.5561

African swine fever

ASF killed or culled ~225 million pigs in China (2018-19), halving the herd; losses near $141B.57

Heat stress rising

Under high emissions, cattle heat-stress losses reach ~$40B/yr by 2100; India could lose 45%+ of dairy output.5667

Who runs it, who checks it, who reforms it

The players

A concentrated field: a handful of firms slaughter most animals, a few regulators set the floor, and a growing set of organizations push the ceiling higher. Badges mark public, private, or cooperative ownership.

Concentration: the top-four grip

Big Four beef packers

Oligopoly

JBS, Cargill, Tyson, National Beef control ~80-85% of US fed-cattle slaughter, up from ~25% in 1977.2829

Demand

Where the meat is eaten

Per-capita meat supply, 2023, carcass weight, excluding fish (FAO via Our World in Data).43 The United States sits near the top; the world average is about a third of it, and India near a tenth.

Two dials, no fake precision

Meat demand is moderately inelastic: price moves consumption, but less than one-for-one. These sliders use published own-price elasticities (beef -0.75, pork -0.72, poultry -0.68).48 They illustrate direction and rough size, not a forecast.

Slide the price change and watch estimated per-capita consumption respond, using the poultry elasticity of -0.68.

Marketing as an input to confidence

Compelled "checkoff" assessments and lobbying flow into consumer confidence at the plate end, the same way feed flows in at the farm end.

Money in
  • ~$750M/yr across all US commodity checkoffs52
  • Beef checkoff: $1/head, ~$38M FY2026 program funding50
  • Pork checkoff: ~$85M 2023 budget51
  • Meat industry: $10M+ US lobbying & contributions, 202353
  • EU spent ~€252M promoting meat & dairy (2016-20)54
Consumer confidence

"Beef. It's What's For Dinner." and similar brand campaigns are funded by these assessments, sustaining demand at the plate.50

Follow the money

Who profits, who pays

Of every dollar spent on US food, the farm gets a shrinking slice; most goes to processing, transport and retail. Growers take on the debt while integrators own the animals.

The US food dollar, 2023

15.9¢ farm
84.1¢ post-farm marketing

Farm establishments received 15.9 cents of each food dollar; the rest went to processing, transport, retail and food service.80

Farm share of retail meat

Beef 41%
retail/packer 59%
Pork 26%
retail/packer 74%

US farmers received ~41% of the retail price of Choice beef and ~26% for pork (May 2022).71

The grower's cut

Median contract broiler grower was paid 6.79¢ per live-weight pound in 2020, with wide "tournament" spread (4.29¢ to 9.64¢).70

Packer margins spike

During the pandemic the four dominant meat processors' net income rose about 500% as beef prices climbed 35%+; margins are cyclical, not always high.7677

Public subsidy

USDA paid $72B+ in direct subsidies to livestock producers, 1995-2023 (cumulative); ~82% of EU CAP supports animal foods.7369

Externalized costs

FAO puts the hidden costs of the whole agrifood system at $10T+/yr; red & processed meat alone carry ~$285B/yr in health costs.7281

Hidden-cost figures cover the entire food system, not animal agriculture alone. They are shown for scale, not as an animal-ag-only total.
