Animal (except Poultry) Slaughtering — U.S. Industry Primer

NAICS 2022 code 311611. NAICS is the North American Industry Classification System, the standard the U.S. government uses to group businesses.

---

1. Overview

This is the "kill floor" of American red meat: the plants that take live cattle, hogs, sheep, lambs, veal calves, goats, bison, and horses and turn them into carcasses and fresh, chilled boxed cuts. In plain terms, it is the beef and pork packing industry. It sits at the exact hinge between the farm and everything downstream — the grocery meat case, the restaurant burger, the export container bound for Tokyo or Seoul.

Why an investor should care: red meat is a roughly $125 billion-a-year U.S. slaughter industry [1] and one of the most consolidated in the entire economy — four companies buy about 85% of all U.S. fed cattle [2]. It is also brutally cyclical. As of early 2026, the U.S. cattle herd stood at 86.2 million head (including 27.6 million beef cows), down 1% year over year and the smallest since 1951 [3][4], which has flipped the economics: ranchers are enjoying record prices while the packers themselves are losing money on every animal [5]. That split — winners and losers moving in opposite directions inside the same supply chain — is the single most important thing to understand here.

The cattle cycle is unusually long — USDA describes an 8-to-12-year cycle because breeding females must be retained rather than slaughtered, then produce calves that take additional time to reach market weight [6]. This structural lag means tight supply conditions persist for years, not quarters.

• Public-market investors can own the giants directly: JBS, Tyson, Smithfield, Seaboard, and Hormel all trade on U.S. exchanges (tickers and detail in Section 4). But note: none is a pure slaughter "play" — each bundles slaughter with downstream branded meats, and in some cases chicken, feed, or even shipping.
• Private-market investors meet this industry through family-owned packers (Cargill, American Foods Group), foreign strategic owners (Brazil's Marfrig, Hong Kong's WH Group), farmer cooperatives (Triumph Foods), and a wave of new rancher- and retailer-backed independent plants being built right now.

2. What it is and how it's structured

Scope. NAICS 311611 covers establishments primarily engaged in slaughtering animals except poultry and small game — and in preparing the fresh and frozen meat that comes directly off that slaughter [7]. A plant that slaughters and then fabricates, cures, freezes, cans, or otherwise prepares its own meat remains in 311611. The core output is carcasses and boxed beef/pork, plus the by-products (hides, tallow, offal, variety meats).

What it explicitly excludes — this matters, because the household-name companies straddle several codes:

• Poultry (chicken, turkey) and small game — that is NAICS 311615, Poultry Processing [7].
• Meat processed from carcasses — sausage, bacon, cured, smoked, and canned meats made from purchased carcasses — is NAICS 311612, Meat Processed from Carcasses [7]. This is where most branded packaged-meat revenue lives.
• Rendering animal fat, bones, and scrap into tallow and meal is NAICS 311613, Rendering and Meat Byproduct Processing [7].
• Purchased-carcass cutting and wholesaling may fall under NAICS 42447 [7].

So when Tyson books beef-jerky or Smithfield books packaged bacon, that revenue is 311612, not 311611. Code 311611 is specifically the harvest-and-fresh-cut step. Tyson describes its beef and pork operations as "harvesting" live animals and fabricating carcasses into dressed and specialty products [8].

Ownership mix. This is a manufacturing industry dominated by a handful of very large, capital-intensive plants — not a fragmented trade of small operators. The federal data count 1,274 establishments run by roughly 1,429 firms [1]. But volume is wildly skewed to the top: fed-beef and hog slaughter is concentrated in a few dozen mega-plants each processing thousands of head per day, alongside a long tail of small regional, state-inspected, and "custom-exempt" locker plants that serve local ranchers and don't ship across state lines. Ownership runs the gamut: U.S.-listed public companies, private family firms, foreign strategic owners, and farmer cooperatives.

3. How big it is

Federal figures for NAICS 311611 (United States):

That works out to average pay of about $56,000 per employee across all roles [1] — but that blends managers and office staff with the line. For the frontline slaughter and meatpacking workforce specifically, the reported national median wage was about $19.13/hour (~$39,800/year) in 2024 [9].

Physical scale. In 2024, U.S. commercial plants produced 54.9 billion pounds of red meat, comprising 27.0 billion pounds of beef, 27.8 billion pounds of pork, 45.3 million pounds of veal, and 139 million pounds of lamb and mutton [10]. Commercial slaughter totaled 31.8 million head of cattle (down 3% year over year) and 130 million hogs (up 1%) [10]. Americans still eat a lot of red meat — USDA projected domestic per-capita availability of 58.5 pounds of beef and 49.7 pounds of pork in 2025, declining to 56.9 and 50.9 pounds respectively in 2026 as cattle supplies tighten [11].

The undercount caveat — read this carefully. Unlike restaurants or construction (which federal business statistics undercount because they are full of tiny operators), red-meat slaughter is well measured — it is concentrated, licensed, and federally inspected animal by animal. The distortion runs the other way:

1. The $124.7B is the slaughter step only. It captures fresh/chilled carcass and boxed-meat value, not the branded, cured, and packaged products the same companies sell (that's 311612). So the company revenues you'll see in Section 4 — JBS's ~$28 billion North American beef unit, Tyson's ~$21.6 billion beef segment — legitimately dwarf a strict reading of this code, because they roll in downstream and by-product sales.
2. Profits often leave the country. Much of U.S. output is captured here at the establishment level, but the ultimate owners of several of the largest packers are Brazilian (JBS, Marfrig) or Hong Kong–based (WH Group), so the earnings flow abroad.

4. The investable universe

There is no pure-play "U.S. slaughterhouse" stock — slaughter is embedded inside larger protein companies. Here is the practical map. (Tickers, share prices, and valuations belong in this section by house convention; figures are recent and will move.)

Public companies

Key point for stock-pickers: buying TSN or JBS is a bet on the beef/pork cycle plus downstream branded margins, not on slaughter alone. Segment disclosures are more informative than consolidated revenue or EBITDA multiples — Smithfield's 2.6% Fresh Pork margin versus 12.5% Packaged Meats margin illustrates why [17]. Dividends and multiples vary — Tyson and Hormel are long-standing dividend payers; JBS and Smithfield are newer to U.S. markets and more cyclical.

Major private and other owners (not directly investable on public markets)

• Cargill (Cargill Protein / Meat Solutions) — privately held; one of the "Big Four" beef packers [2].
• American Foods Group — third-generation family-owned beef packer; building the new America's Heartland Packing plant in Missouri [21].
• Regional beef packers — Greater Omaha, Central Valley Meat, Caviness, Harris Ranch, Nebraska Beef.
• Pork — Triumph Foods (farmer-owned cooperative; Seaboard JV partner), Clemens Food Group, Prestage Foods.
• New independents (2025 wave) — Sustainable Beef (North Platte, NE, backed in part by Walmart) and Cattlemen's Heritage (Iowa), both rancher-/retailer-aligned projects aimed at breaking the Big Four's grip [21].

5. How the money works

Packers do not primarily bet on the price of meat going up. They earn a conversion spread — the industry calls it the packer margin or gross packer margin:

Packer margin ≈ (boxed-meat "cutout" value + by-product "drop credit") − (cost of the live animal) − (processing cost)

National Beef explicitly states that profitability depends on this spread and overall volume, and that it has limited influence over either cattle prices or finished-product prices [20].

• Buy the animal, sell the box. A packer buys a live steer or hog, harvests it, and sells the resulting boxed beef/pork "cutout" to grocers, foodservice, and exporters. The gap between what the box fetches and what the animal cost — minus labor and plant overhead — is the profit. Plants procure livestock through cash markets, formula arrangements, forward contracts, and producer alliances [8].
• The "drop credit." Everything that isn't a primal cut — hides, tallow, blood, bone, and variety meats (offal) — is sold separately. This by-product revenue is real money and swings margins. National Beef says boxed beef and beef byproducts generate most of its revenue, supplemented by consumer-ready products, wet-blue leather, direct-to-consumer steaks, and refrigerated transportation [20]. Variety-meat exports in particular add meaningful value per head.
• Throughput is everything. Plants are enormous fixed-cost machines. Profit depends on running them full. Capacity utilization is the master dial: when cattle are plentiful, plants run near 85%+ and margins are healthy; when cattle are scarce, utilization falls (to ~77% in fall 2025) and per-head margins go negative [5]. In fall 2025 beef-packer margins ran around −$126 to −$166 per head [5] — the plants were losing money on nearly every animal because tight cattle supply bid live prices above what the boxed beef could recover.
• Scale matters. USDA reports that the average beef plant owned by a top-four packer processed 417,000 cattle in 1980 and more than 1 million in 2002 [22]. The industry had roughly 8% excess designed beef capacity in 2015; later, operating at or above design levels increased overtime and maintenance expense [22]. USDA estimated approximately $300 million to build a beef plant designed for 1,500 head per day [22] — Cattlemen's Heritage is a ~$520M project, Sustainable Beef ~$325M [21].
• Beef vs. pork models differ. In beef, packers mostly buy cattle on the open and formula (contract) market — they don't own the animals, so they're squeezed when the cattle cycle shifts bargaining power to ranchers. In pork, the leaders are vertically integrated — Smithfield and Seaboard own or contract the hogs from birth, smoothing supply and capturing margin across the chain. Smithfield's fiscal 2025 operating margins illustrate the gap: 2.6% in Fresh Pork versus 5.2% in Hog Production and 12.5% in Packaged Meats [17].
• Exports lift the whole thing. Selling cuts and offal that Americans won't eat (tongues, tripe, feet, hearts) into Asia and Mexico adds value that would otherwise be near-waste. In 2024, U.S. pork exports hit a record $8.63 billion (~7.1 billion pounds, a record ~30% of production) and beef exports $10.45 billion (~3.0 billion pounds) [23][24][25] — worth roughly $415 per fed-beef head and $66.53 per hog in export value [23]. Japan, South Korea, China, Mexico, and Canada took 78% of beef export volume; Mexico and Japan together took more than 40% of pork [24][25].

Recent public results show that high meat prices do not necessarily mean high packer profits. In fiscal 2025 Tyson's Beef segment generated $21.6 billion of sales but a $1.1 billion operating loss (−5.2% margin); its Pork segment generated $5.8 billion of sales and a $199 million operating loss (−3.4% margin) [8][15]. National Beef's minority owner recorded an equity loss because higher cattle prices, reduced volume, and lower gross margin per head overwhelmed higher selling prices [20].

The takeaway: this is a spread-and-throughput business layered on top of a biological commodity cycle. Owners make money by running full plants and capturing a stable conversion margin — and lose money when the animal supply tightens faster than they can pass costs through.

6. What drives demand

• Population and income. More people and rising incomes mean more protein eaten; red meat is a staple, though its share has slipped as chicken rose.
• Consumer prices and substitution. Shoppers trade among beef, pork, and chicken on relative price. When beef gets expensive (as in 2025–26), some demand shifts to pork and poultry — a tailwind for hog packers. In 2025, average retail beef-and-veal prices rose 11.6% even as constrained cattle availability hurt packer utilization [26]. The strongest long-term substitution trend is toward chicken, whose short biological cycle, feed conversion, and integrated production support lower relative prices.
• Foodservice vs. retail. Restaurant and away-from-home demand drives higher-value cuts; grocery drives ground and everyday cuts. Both track the broader economy.
• Exports. A structural growth lever — Mexico, Japan, South Korea, China, and Canada are major buyers. Trade access (tariffs, sanitary bans) can swing volumes materially. USDA projects pork exports increasing from 7.2 billion pounds in 2026 to 7.8 billion in 2035, supported by heavier animals, pigs-per-litter productivity, foreign income growth, and weaker European supply growth [27].
• The livestock cycle (supply side). Because it takes years to breed and raise cattle, red-meat supply moves in long waves independent of demand — the dominant driver of packer economics (Section 9).
• Feed costs. Corn and soybean prices set the cost of raising the animal; cheaper feed encourages herd expansion (eventually more animals to slaughter).
• Emerging wildcard. GLP-1 weight-loss drugs (glucagon-like peptide-1 medications) may modestly reshape protein demand over time — this is a forward-looking, unsettled question, not an established trend.

---

7. Regulation

Red-meat slaughter is one of the most heavily regulated activities in U.S. manufacturing.

• Mandatory federal inspection. Under the Federal Meat Inspection Act (FMIA) of 1906, the USDA's Food Safety and Inspection Service (FSIS) — USDA is the U.S. Department of Agriculture — places inspectors continuously in every federally inspected plant and examines every carcass [28]. Plants that ship across state lines must run under FSIS (or an equivalent state program). FSIS conducts ante- and post-mortem inspection and oversees sanitation, adulteration, labeling, and humane slaughter [28][29].
• HACCP. Every plant operates a Hazard Analysis and Critical Control Points food-safety plan — a systematic process-control regime for microbial and physical hazards. Plants must maintain validated HACCP systems, sanitary dressing controls, and prevent fecal, ingesta, and milk contamination [29][30].
• Humane handling. The Humane Methods of Slaughter Act (HMSA) governs how animals are handled and stunned.
• Line speed — an active fight. How fast the kill/disassembly line runs sets both output and worker-injury risk. FSIS is moving to let plants under the New Swine Slaughter Inspection System (NSIS) set their own line speeds, potentially removing the long-standing 1,106 heads-per-hour cap, with a comment period running into April 2026 [31]. Industry says this improves affordability; labor and safety advocates warn it raises injury risk [31]. Watch this rulemaking — it directly affects plant throughput and thus margins.
• Fair-competition oversight. The Packers and Stockyards Act (P&SA) of 1921, administered by USDA, polices how packers buy livestock and compete — addressing prompt payment, producer protection, and unfair, deceptive, or discriminatory conduct [32]. This is the legal backbone for concerns about packer power over ranchers.
• Antitrust. The Department of Justice and USDA have ramped up scrutiny of the "Big Four" beef packers [2], and price-fixing/wage-suppression litigation is ongoing (Section 8).
• Environmental regulation. Wastewater is both a cost and a permitting constraint. Federal rules under 40 CFR Part 432 regulate direct discharges from slaughterhouses and other meat processors [33]. EPA withdrew a proposed tightening of these standards in August 2025; existing federal, state, and local permits still require substantial treatment infrastructure [33].
• Labor and immigration. Plants answer to OSHA (the Occupational Safety and Health Administration) for worker safety and to federal immigration/I-9 enforcement — a live risk, as more than half of meatpacking workers are immigrants [34]. OSHA identified 9,882 submitted incidents in the broader animal-slaughtering-and-processing industry during 2024; 88% came from establishments with at least 250 workers, and hearing-loss cases were disproportionately common [35].
• Labeling and trade. A finalized "Product of USA" voluntary-labeling rule tightened origin claims, and export access depends on foreign sanitary approvals.
• Foreign-ownership scrutiny. Brazilian and Hong Kong ownership of major U.S. packers draws recurring political and national-security attention.

8. Competitive dynamics and consolidation

This is a textbook oligopoly, especially in beef.

• The Big Four. JBS, Tyson, Cargill, and National Beef (Marfrig) buy roughly 85% of U.S. fed cattle [2] and control about 73% of fed-cattle slaughter capacity [2]. In 1980 the top four handled about a third of cattle purchases; by the mid-1990s that had climbed to ~80% as plants scaled up and small, high-cost facilities closed [2]. USDA ERS reports the four largest packers handled 85% of steer-and-heifer purchases and 67% of hog purchases (hog figure measured in 2019) [22].
• Plant-level concentration. As of 2024, the 12 largest cattle plants processed 51% of cattle, while the 15 largest hog plants processed 64% of hogs [10]. USDA reported 1,089 federally inspected livestock-slaughter plants at the beginning of 2025 [10].
• The federal concentration data, read correctly. For all of NAICS 311611 (which mixes cattle, hogs, sheep, and more), the four largest firms hold 66% of revenue, the top eight 79%, the top 20 89%, with a Herfindahl-Hirschman Index (HHI, a standard concentration score) of about 1,251 [1]. On its face 1,251 looks only "moderately" concentrated — but that number blends distinct sub-markets. The fed-beef slice specifically is far more concentrated (~85%) [2]; the diverse category average understates it. The most common misstatement is that "four firms control 85% of the meat industry" — the evidence supports 85% of steer-and-heifer purchases, not 85% of pork, all 311611 revenue, or total slaughter capacity.
• Pork is also concentrated — Smithfield (~23% fresh-pork share), JBS, Tyson, Seaboard, and Hormel dominate [18] — but slightly less so than beef, and more vertically integrated.
• Barriers to entry are high. A modern plant costs hundreds of millions of dollars — Cattlemen's Heritage is a ~$520M project, Sustainable Beef ~$325M [21] — on top of regulatory approval, a reliable livestock supply, and a workforce willing to do hard, dangerous work.
• Litigation is a recurring cost. Tyson and Cargill agreed to pay a combined $87.5 million to settle beef price-fixing claims (JBS and National Beef continued litigating) [36], and separate pork price-fixing settlements — Smithfield $75M, Tyson, JBS, Seaboard, Hormel, Clemens, Triumph — plus a $200 million wage-suppression settlement have piled up [37].
• The counter-movement. Ranchers, retailers (Walmart), and the USDA — via the $500 million SPUR (Strengthening Processing for U.S. Ranchers) program [21] — are funding new independent plants (Sustainable Beef, Cattlemen's Heritage, America's Heartland) explicitly to dilute Big Four power. Whether they can survive a down-cycle is an open question.

---

9. Risks

• The cattle cycle — the dominant risk. The U.S. cattle herd is at a ~74-year low (86.2 million head on January 1, 2026, smallest since 1951) after years of drought and high feed costs [3][4]. Too few cattle means idle plant capacity and negative packer margins — exactly today's condition in beef [5]. This is structural and slow to reverse; USDA describes an 8-to-12-year cycle [6].
• Input-cost squeeze. The live animal is the single largest cost. When livestock prices rise faster than boxed-meat prices, margins vanish — packers can't simply pass it all through. National Beef explicitly acknowledges limited influence over either cattle or finished-product prices [20].
• Animal disease. African Swine Fever (ASF) would be catastrophic for U.S. pork if it ever arrived; foot-and-mouth disease (FMD), New World screwworm, and, historically, bovine spongiform encephalopathy (BSE, "mad cow") can shut export markets overnight. A single confirmed case can trigger immediate import bans by trading partners.
• Labor. High turnover, injury rates, unionization, wage pressure, and — acutely in 2025 — immigration enforcement. ICE raids have cut individual plants' output to as low as 20% of normal [34]; with over half the workforce foreign-born [34], sustained enforcement is a real supply risk. Work is repetitive, physically demanding, and often located in rural markets with limited labor pools.
• Regulatory and legal. Antitrust probes, price-fixing and wage-suppression settlements, and shifting line-speed and inspection rules all bear directly on cost and throughput.
• Trade. Tariffs, currency swings, and sanitary bans can close key export markets (China's periodic pork and beef restrictions are the clearest example).
• Operational fragility. Concentrated capacity means the loss of one very large plant can materially alter regional cattle bids and national slaughter throughput. Cyberattacks, plant fires, refrigeration failures, and freight disruptions are all material risks.
• Reputation / ESG. Animal welfare, worker safety and child-labor scandals, greenhouse-gas emissions, and (for JBS and Marfrig) Amazon-deforestation exposure are ongoing pressures that affect financing, customer relationships, and political risk.
• Thin, cyclical margins. Even in good years this is a low-margin, high-fixed-cost commodity business; earnings can swing violently year to year.

10. How to invest and the outlook

Public-market routes

• Diversified giants: JBS (NYSE: JBS), Tyson (NYSE: TSN), Smithfield (Nasdaq: SFD), Seaboard (NYSE American: SEB), Hormel (NYSE: HRL), or WH Group (HKEX: 0288). Understand which protein and which stage each is weighted to — Tyson and JBS carry the most direct beef-cycle exposure; Smithfield and Seaboard are the pork-integration plays; Hormel is mostly branded/processed.
• What you're actually buying: a cyclical commodity-processing business layered with downstream branded margins. These are value/cyclical names, not steady compounders. Tyson and Hormel offer established dividends; JBS and Smithfield are newer, more volatile U.S. listings. It is wrong to equate high retail beef prices with high packer profits — the current cattle shortage produces the opposite combination.

Private-market routes

• Direct ownership is concentrated among private/family firms (Cargill, American Foods Group), foreign strategics (Marfrig, WH Group), and cooperatives (Triumph, U.S. Premium Beef). Private equity plays the sector mainly through downstream processing, cold-chain logistics, and pet-food/rendering by-products rather than the kill floor itself.
• The new independent plants (Sustainable Beef, Cattlemen's Heritage, America's Heartland) — often rancher-, retailer-, or USDA-SPUR-backed — are a distinct, higher-risk, mission-driven way in. Underwriting must focus on livestock density and procurement radius, committed supply, customer offtake, wastewater and air permits, FSIS readiness, labor availability, refrigeration, construction and ramp risk, working-capital needs, and achievable — not announced — throughput.
• Related exposure without owning a packer: cattle and farmland, feed/grain, cold storage and logistics, and animal-health suppliers.

Near-term outlook (forward-looking judgment)

• Beef looks hard before it looks better. With the herd at a multidecade low, packer margins are expected to stay pressured and plant utilization soft through 2026 [5]. Meaningful herd rebuilding isn't forecast to gather pace until 2027 and beyond, because breeding back a herd takes years [3][6]. Ironically, several new beef plants are opening into this cattle shortage — raising the risk of overcapacity chasing too few animals.
• Pork is the steadier story. Hog supply is ample, exports set records in 2024, and integrated pork margins have been improving [14][23] — the relative winner near term, helped by consumers trading down from pricey beef.
• Watch three switches: the FSIS line-speed rulemaking (throughput), the DOJ/USDA antitrust posture and immigration enforcement (cost and labor supply), and the first hard evidence of herd rebuilding (the turn that eventually re-widens beef-packer margins).

Bottom line: a large, essential, heavily consolidated, foreign-influenced industry running through the bottom of a punishing cattle cycle. Public investors get cyclical exposure via a short list of protein conglomerates; private investors meet it through family firms, cooperatives, and a fresh crop of independent challengers. Whoever owns it, the profit comes down to two levers — a full plant and a healthy conversion spread — and right now, in beef, both are working against the packers.
