Animal Production and Aquaculture (United States) — NAICS 112

A Histometrics rollup primer for public-market and private investors. The North American Industry Classification System (NAICS) is the federal standard the United States, Canada, and Mexico use to sort businesses by activity; this page covers the 2022 revision, subsector 112 (three-digit), "Animal Production and Aquaculture." It is the whole farm-gate animal economy — every establishment whose primary business is raising animals for food, fiber, breeding, sport, or research. The subsector contains six industry groups (four-digit): 1121 Cattle Ranching and Farming, 1122 Hog and Pig Farming, 1123 Poultry and Egg Production, 1124 Sheep and Goat Farming, 1125 Aquaculture, and 1129 Other Animal Production. This primer synthesizes the six child primers and adds the cross-child comparison that is its distinctive value. Tickers, yields, and multiples are reserved for the investable-universe and how-to-invest sections; every acronym is defined on first use.

1. Overview

NAICS 112 is American animal agriculture at the farm gate — the barn, the pasture, the feedlot, the parlor, the pond, and the ranch, but not the slaughter plant, the dairy, the cheese vat, or the branded package, which all sit in separate manufacturing codes (chiefly NAICS 311). It is one of the largest blocks of the U.S. farm economy: cattle and calves alone generated about $112.1 billion of farm cash receipts in 2024, which USDA (the U.S. Department of Agriculture) reports as 41.7% of all U.S. animal-product receipts — implying a subsector on the order of ~$270 billion at the farm gate, plus a roughly $1.9 billion aquaculture business measured separately [1][2].

The distinctive fact of this level is contrast, not blend. The six children do not compete for one customer or share one profit driver. They range from a $160-billion cattle-and-milk giant to a sub-$1-billion sheep-and-goat niche; from a decades-long chicken growth story to a terminally declining fur business; from vertically integrated oligopolies that own the animals and pay farmers a fee, to hundreds of thousands of independent family ranches that own their herds outright. What ties them together is not economics but biology and structure: living inventory on a breeding clock, feed as the master input, disease as the master risk, relentless consolidation, and a producer base so dominated by small private operators that the whole subsector is invisible in standard federal business statistics.

For an investor of any kind, the through-line is that the production layer is overwhelmingly private — families, partnerships, trusts, land companies, cooperatives, integrators, and hobbyists. Listed capital reaches the theme mostly around the edges: downstream processors, input suppliers, farmland, futures, and a handful of near-pure-plays clustered in just two of the six children. This primer's job is to show where value, growth, and access concentrate across the six before treating the subsector as a whole.

2. What's inside — the six children and how they differ

The subsector is really three large protein businesses (cattle, poultry, hogs) that carry ~98% of the dollars, plus three small specialty businesses (other animals, aquaculture, sheep/goats) that together are ~2% — but the small ones include the only clean public equity in the whole group's residual corner. The table leads with what each child produces, its share of the subsector, its direction of travel, who owns it, and how an investor reaches it; the numbers are unpacked in §3–§5.

The through-line. Two things investors usually conflate — where the output is and where the investable public value is — point at different children here. By dollars, the subsector is cattle, then poultry, then hogs, and everything else is a rounding error. By clean public access, the ranking scrambles: the giant (cattle) has the worst public route (indirect proxies only, and the most liquid beef proxy — meatpackers — actually loses margin when cattle prices boom); the mid-sized children (poultry and hogs) have the best (egg pure-plays, a chicken oligopoly, and the one listed hog "farmer," Smithfield); and the residual bucket (1129) holds the single highest-quality public name in the group (Charles River, in laboratory animals) even though its farm output is tiny. Sheep/goats and aquaculture are private-first specialist corners with only foreign or diffuse proxies. The one name that spans the most of the subsector at once is Tyson, which reaches into beef, pork, and chicken under a single ticker.

3. How big it is (this subsector's rollup)

A note on our figures. Our ingested ground-truth stats file for NAICS 112 (stats-112.md) contains no stat_metrics at all — there are no ingested figures for this node, and none for any of its six children either. We say so plainly rather than manufacture a number. Every figure below is carried up from the six child primers and labeled to its cited public source (USDA, the U.S. Small Business Administration, NOAA, and company filings), not drawn from an internal dataset.

The economic rollup (farm gate, USDA Economic Research Service — ERS — and National Agricultural Statistics Service — NASS). There is no single ingested "112" total, and the children are measured in different years and on different bases, so this is an approximate reconstruction, not a precise sum:

Because cattle and calves are 41.7% of all U.S. animal-product receipts [1], the implied animal-products total is roughly $270 billion (2024) — of which cattle-and-milk is ~60%, poultry-and-eggs ~26%, hogs ~11%, and sheep/goats, aquaculture, and other animals together ~2–3%. Read this as orders of magnitude, not decimals: aquaculture (measured by USDA's separate Census of Aquaculture) and much of 1129 (honey, pollination services, horses, laboratory animals) sit partly outside the ERS animal-product receipts series, so the true economic footprint is somewhat larger than $270B and is genuinely hard to total cleanly.

Physical scale (USDA NASS), to convey the tonnage behind the dollars: ~86.2 million cattle and calves (January 1, 2026 — the smallest since ~1951) [9]; ~73.7 million hogs [5]; ~9.33 billion broilers and ~365 million laying hens producing ~105 billion eggs a year [4]; ~7.5 million sheep and goats [8]; ~3,453 aquaculture farms selling ~$1.9B of fish and shellfish [7]; and, in the residual, ~2.4 million horses on farms, ~3.8 million bee colonies, and a global research-animal market near $2.4B [6].

SBA size standards (the U.S. Small Business Administration's program-eligibility thresholds, not revenue measures) show how differently the children are built: a beef ranch counts as "small" up to $2.5M in average annual receipts, a dairy farm to $3.75M, a hog farm to $4.0M, and a cattle feedlot all the way up to $22.0M — because feed passes through the yard as revenue [3][5]. Gross receipts are a poor gauge of where profit actually sits at this level.

Undercount caveat (large, and it applies to the whole subsector). Do not reach for the usual "business statistics" here. The Census Bureau's payroll-business programs — the Economic Census, County Business Patterns (CBP), and Statistics of U.S. Businesses (SUSB) — and its Nonemployer Statistics all exclude Sector 11 (agriculture) entirely, including every part of subsector 112 [10][11]. The Bureau of Labor Statistics' employment census likewise misses most self-employed and small-farm labor. So there is no Census establishment count, payroll, or receipts total for NAICS 112, and none should be inferred. The authoritative counts come instead from USDA's Census of Agriculture (every five years) and NASS commodity surveys, which measure animals, farms, and farm value — not "firms" and "revenue." Because the producer base is dominated by very small, often individually owned or hobby operations — most acutely in sheep/goats, aquaculture, apiculture, horses, and cow-calf ranching — any employer-firm lens badly understates the subsector's true footprint. The gap is small family and non-employer farms, not government ownership. Some children are genuinely unmeasured (dual-purpose cattle, most rabbitries, recreational horses); the honest way to size 112 is by head, farms, volume, and receipts, and to accept the edges are fuzzy.

4. The investable universe — where value concentrates across the children

There is no pure-play public company for most of this subsector's production, and where listed access does exist it is bunched into two of the six children. The dollars sit in cattle, poultry, and hogs; the clean public equity sits in poultry, hogs, and — for the residual — lab animals; and the two rankings famously diverge. Tickers below are for the access discussion only.

Diversified protein giants that span several children (the broadest handles):

Near-pure-plays, clustered in two children:

• Poultry (1123) — the only child with listed pure-plays. Cal-Maine Foods (CALM), the largest U.S. shell-egg producer and the most direct bet on the egg commodity cycle; Vital Farms (VITL), a branded pasture-raised specialty grower; and Pilgrim's Pride (PPC), the closest thing to a listed chicken pure-play (JBS-controlled) [4].
• Hogs (1122) — one listed "farmer." Smithfield Foods (Nasdaq: SFD), the only large listed company whose identity is pork/hogs (though ~91% still controlled by WH Group, HKEX: 0288, so float is thin) [5].
• Other (1129) — one scaled listed name in the residual. Charles River Laboratories (NYSE: CRL), whose research-models segment (~$829M of ~$4.05B revenue) is the only scaled public route into laboratory-animal breeding — you are buying a drug-development-services firm, not a livestock play [6].

Where the big child (cattle) leaves you with proxies only: listed ranch land (Tejon Ranch, TRC), cattle futures and notes (CME live-cattle LE, feeder-cattle GF; the iPath Livestock ETN, COW), dairy demand names (Coca-Cola/fairlife KO, Saputo SAP, Danone BN, Nestlé NESN, General Mills GIS, Kraft Heinz KHC) and dairy cost names (Zoetis ZTS, Elanco ELAN, Deere DE, Archer-Daniels-Midland ADM), and farmland real-estate investment trusts (REITs: Gladstone Land LAND, Farmland Partners FPI) [3]. Aquaculture is reached only through foreign salmon majors (Mowi, SalMar, Bakkafrost, Grieg) [7]; sheep/goats only through foreign specialty-dairy (Emmi, Saputo, Savencia), protein majors, and farmland REITs [8].

Where the private ownership really sits: the production layer of every child. Cattle as land and herds (King Ranch, mega-dairies, farmer co-ops like Dairy Farmers of America) [3]; hogs and poultry as integrator systems + contract barns (Smithfield, Wayne-Sanderson, Perdue; the Aviagen/Cobb-Vantress genetics duopoly) [4][5]; sheep as scarce processing capacity (employee-owned Superior Farms, ~1/3 of inspected lamb) [8]; aquaculture as vertically integrated privates (Cooke, Pacific Seafood, Taylor Shellfish) [7]; and the residual as passion- and IP-driven privates (the Kentucky Thoroughbred complex, The Jackson Laboratory, Turner's bison) [6]. The recurring pattern: value pools wherever customers pay for genetics, biosecurity, logistics, scale, and regulatory standing — which is why lab animals and vertically integrated poultry/hogs scale into real industries while ranching, aquaculture, and small ruminants stay fragmented.

The practical takeaway: public equity captures none of the six farm codes cleanly, and the cleanest routes are not where the money is. A bull on beef, a bull on chicken, and a bull on farmed salmon buy entirely different (and often foreign or inverse) names.

---

5. How the money works

Despite the diversity, most of the subsector runs on one recurring model — a "crush-style" margin: the value of the finished animal or product minus the cost of the feed and the young stock that went into it — layered on top of biological inventory on a breeding clock. This is a farm, real-asset, and industrial-supply subsector: do not force regulated-utility rate-base, REIT funds-from-operations, or mining all-in-sustaining-cost language onto it. The appropriate metrics are head, price per hundredweight (cwt = 100 pounds), feed-conversion and crush spreads, cost per unit, and survival/breeding rates.

• Feed is the swing input almost everywhere. Corn and soybean meal dominate the cost base of confined species — roughly half of hog production expense, half to two-thirds of poultry cost, and the primary swing cost in dairy and feedlot cattle [4][5]. When output prices are high and grain is cheap, margins are fat; the reverse crushes them. The exceptions run on land and forage instead of purchased feed: cow-calf ranching, sheep and goats, and — most cleanly — shellfish, which filter wild plankton and buy no feed at all [3][7][8].
• Two structural ownership models recur. In poultry and hogs, a vertically integrated integrator owns the animals and feed and books most profit downstream in processing, while thousands of contract growers invest in debt-financed barns for a per-head or per-pound fee — carrying the capital and volatility but not the price risk [4][5]. In cattle, dairy, and sheep/goats, independent producers own their animals outright and sell into concentrated buyers (packers, cooperatives, processors), keeping the price risk themselves [3][8].
• Biology sets the cycle, and the cycles differ by species. The cattle cycle runs ~8–12 years and is at a scarcity peak that rewards owners and squeezes feeders [3]; the pig cycle turns faster and flipped the hog sector to whole-year losses as recently as 2023 [5]; poultry is whipsawed less by a breeding cycle than by disease shocks (see §9); and horses breed to a market three years out they cannot yet see [6]. Long production lags amplify boom-bust everywhere.
• Value migrates by segment. In dairy, sheep, goats, and aquaculture, raw output (milk, wool, raw goat milk) is worth little and the margin sits downstream in cheese, branded lamb, or processing — so vertical integration is decisive [3][8][7]. In beef, the land is the balance sheet and can appreciate while the cattle enterprise merely breaks even [3]. In lab animals, purpose-bred genetics and biosecurity command licensing-like, recurring economics [6].
• Government cash is real. USDA indemnities for flocks destroyed during bird-flu outbreaks, the dairy Federal Milk Marketing Order and Dairy Margin Coverage, livestock insurance, and Farm Bill wool/mohair loans are genuine inflows to model in any diligence [3][4].

6. What drives demand

Demand splits by product, which is why the children move on different news — but a few forces cut across the whole subsector:

• Protein substitution. Chicken is the cheapest animal protein and the group's structural growth engine, taking share whenever record-priced beef and pork get expensive; per-capita chicken has risen for decades [4]. Beef holds a premium, resilient even at record retail prices [3]; pork is mature; lamb and goat are tiny niches concentrated in ethnic and religious communities [8].
• Feed and forage cost is a demand driver and a cost driver at once — corn is a cost to the feedlot and a signal to the rancher; drought and pasture conditions gate margins across grazing species [3][4].
• Exports tie farm prices to the world. Pork ships ~25% of output abroad (a record $8.63B in 2024), beef and dairy solids a meaningful share, broilers ~14% — so trade policy, currency, and foreign disease outbreaks (African Swine Fever abroad can surge U.S. pork demand) swing farm-gate prices [4][5].
• Premiumization and welfare demand reshape economics segment by segment — cage-free eggs, pasture-raised, antibiotic-free, artisan goat cheese, and state welfare laws create compliant/non-compliant market splits [4][8].
• The import gap is aquaculture's distinctive tailwind: the U.S. imports ~80% of its seafood against a ~$20.3B trade deficit, giving domestic fish and shellfish farming a genuine structural case even at tiny current scale [7].
• Systemic and derived demand anchor the residual: honey-bee pollination underpins tens of billions of dollars of other crops, and lab-animal demand is derived from biopharma R&D budgets [6].

---

7. Regulation

There is no single regulator for NAICS 112; the burden lands unevenly, lightest on the open pasture and heaviest on the confined feedlot, mega-dairy, and integrated barn. The common federal stack, mostly USDA:

• Animal health & disease (all children). USDA's Animal and Plant Health Inspection Service (APHIS) runs disease control, traceability (electronic cattle ear-tags since 2024), and the response to highly pathogenic avian influenza (HPAI) in poultry and the H5N1 strain now in dairy cattle, plus the National Scrapie Eradication Program for sheep and goats and Chronic Wasting Disease controls for farmed cervids [3][4][8].
• Meat & product inspection. USDA's Food Safety and Inspection Service (FSIS) runs mandatory slaughter inspection downstream; a shortage of small inspected plants is a real constraint for lamb, goat, and aquaculture producers [3][8].
• Market conduct. USDA's Agricultural Marketing Service (AMS) enforces the Packers and Stockyards Act governing livestock and poultry-contract fairness — central to the concentration debate (§8) [4][5].
• Environment. The Environmental Protection Agency (EPA) permits large operations as Concentrated Animal Feeding Operations (CAFOs) under the Clean Water Act, biting on feedlots, mega-dairies, and hog/poultry barns far more than on pasture [3][4][5].
• Where the children diverge sharply: the dairy Federal Milk Marketing Order price-setting system (overhauled June 2025) [3]; state animal-welfare sales laws (California Proposition 12, upheld by the Supreme Court in 2023; Massachusetts Question 3) that reset hog and egg economics nationally [4][5]; state fur-sale bans [6]; the Horseracing Integrity and Safety Act and IRS hobby-loss rules for horses [6]; the FDA's move to phase out animal-testing requirements, the key long-run swing for lab animals [6]; and a fragmented, farm-specific permitting maze (EPA, FDA, Army Corps, NOAA, states) that is itself a barrier to entry in aquaculture [7].

---

8. Consolidation

The defining structural fact of the whole subsector is hundreds of thousands of small producers facing a handful of large buyers — and consolidation is advancing in every child, though by different mechanisms:

• Cattle (1121). Ranching is a fragmented base gently concentrating; feeding is already consolidated; and both sell into the most concentrated tier of all — the "Big Four" beef packers (Tyson, JBS, Cargill, National Beef) handle ~85% of steer-and-heifer slaughter, a near-oligopsony now under an intensified DOJ (Department of Justice) antitrust probe. Dairy shows relentless farm attrition (licensed herds down ~65% since 2004) even as output climbs [3].
• Hogs (1122). Farm numbers are down >70% since 1990; slaughter is a top-three oligopoly (~60% combined). Notably, the biggest players are partly deconsolidating the farming step — Smithfield deeding sows back to independent growers — judging that owning the volatile hog-raising piece is less attractive than buying hogs and focusing on branded meat [5].
• Poultry (1123). Tight oligopolies throughout (broilers top-4 ~55–60%, eggs top-10 ~54%, a 72–78% genetics duopoly), with foreign and private-equity capital entering U.S. assets and antitrust as a live overhang (a 2026 DOJ action against the Agri Stats data exchange; egg-benchmark litigation) [4].
• Sheep/goats (1124) & aquaculture (1125). Production is essentially un-consolidatable — too small, too biological, too site-specific — so consolidation sits downstream and abroad (Superior Farms in lamb processing; foreign specialty-dairy in goats; integrated privates like Cooke in aquaculture) [7][8].
• Other (1129). The children run in opposite directions — lab animals concentrating behind high barriers, apiculture consolidating at the top, fur in terminal contraction, horses shrinking and premiumizing [6].

Across the subsector, consolidation advances more through contracts, cooperatives, producer-owned processing, integrator relationships, and land aggregation than through wholesale replacement of independent farms.

---

9. Risks

• Disease — the master, shared risk. This is the single most important thing to understand about 112. H5N1 avian influenza jumped into dairy cattle in 2024 (1,000+ herds) and has devastated poultry (166M+ birds since 2022); African Swine Fever abroad is the hog sector's tail risk; New World screwworm advancing through Mexico threatens beef; scrapie, Chronic Wasting Disease, colony collapse in bees, and Vibrio/algal kills in shellfish round it out. Biological inventory can vanish suddenly, and breeder/hatchery flocks take a year-plus to rebuild [3][4][6][7].
• Two (or six) different cycles. Beef sits at a record peak that will eventually turn; hogs can post whole-year losses; poultry earnings are whipsawed by bird-flu shortages; horses and mink are brutally cyclical. A shock good for one child can be neutral or bad for another [3][5][6].
• Feed and weather. Corn, soybean meal, hay, drought, and pasture conditions swing margins across nearly every child at once [3][4][5].
• Buyer concentration. Cattle sell into a near-oligopsony of packers; hogs and poultry into concentrated integrators; dairy through co-ops into a concentrated processor base — all weakening farm-gate bargaining power and drawing antitrust scrutiny [3][4][5].
• Trade and policy. Export dependence (pork ~25%, broilers ~14%) exposes the subsector to tariffs, currency, and border closures; welfare laws (Prop 12) impose compliance costs and market splits [4][5][8].
• Illiquidity, leverage, and succession. Land, animals, and barns are capital-heavy and often financed; interest rates feed straight into feedlot closeouts and barn debt; illiquid, high-priced assets make exits and generational transfer hard.
• For investors specifically. No liquid pure-play equity exists for most children; the cleanest beef proxy (packers) is an inverse bet on scarce, expensive cattle; futures are leveraged and volatile; and reliable data lags (the five-year Census of Agriculture and Census of Aquaculture) far behind other sectors' monthly reporting [3][7].

---

10. How to invest & outlook

Match the vehicle to the child — the routes differ sharply, and none is a clean bet on the subsector as a whole.

Public-market routes (mostly indirect):

• Broadest single handle: Tyson (TSN) or JBS (JBS) span beef, pork, and chicken — read them as integrated, commodity-cyclical protein equities valued on mid-cycle earnings and feed spreads, not one year [3][4][5].
• Poultry (best access): Cal-Maine (CALM) for the egg commodity cycle, Vital Farms (VITL) for premium-brand growth, Pilgrim's (PPC) for chicken [4].
• Hogs: Smithfield (SFD) is the one listed "farmer"; Seaboard (SEB), Hormel (HRL), WH Group (0288) are diversified alternatives [5].
• Cattle (proxies only): packers (TSN, JBS — but note the inverse margin), listed ranch land (Tejon, TRC), CME cattle futures (LE, GF) or the Livestock ETN (COW), and dairy demand/cost equities (KO, SAP, ZTS, DE, ADM) [3].
• Aquaculture: foreign salmon majors (Mowi, SalMar, Bakkafrost, Grieg) — the only liquid route, and non-U.S. [7].
• Other (1129): Charles River (CRL) for lab animals; horse-adjacent racing/gaming and animal-health names (CHDN, ZTS, IDXX) [6].
• Diffuse: farmland REITs (LAND, FPI) and agribusiness ETFs (e.g., MOO) give land/input exposure with no species tilt; there is no cattle, hog, sheep, goat, or aquaculture ETF [3][8].

Private routes (how the subsector is really owned): direct ranch, farm, herd, barn, pond, or land ownership; contract growing (a leveraged, single-customer real-estate-and-labor bet on one integrator); cooperative membership; producer-owned processing; the genetics, feed, animal-health, and cold-chain "picks-and-shovels" layer; and growth/venture capital into integrated platforms, lab-animal/CRO (contract research organization) operators, and ag-tech. Diligence should center on normalized cash flow after feed, labor, veterinary costs, mortality, freight, land rent, and interest, plus disease/indemnity history, customer concentration, permit and lease standing, and succession.

Outlook (forward-looking judgment, not a forecast of record). Read 112 not as one industry but as six clocks running at once. Cattle sits at a genuine 75-year scarcity extreme — record prices favoring ranchers who own animals and squeezing feeders who must buy them, with no meaningful herd rebuild expected before ~2028 [3]. Poultry is a structurally growing, consolidating, bird-flu-whipsawed complex — the best public access in the group [4]. Hogs are a mature, export-sensitive, cyclical commodity whose majors are shifting risk toward packaged meat [5]. Sheep/goats offer a cyclical lamb-price high bolted to a slow goat-demand tailwind, both private and import-capped [8]. Aquaculture is a compelling import-substitution story wrapped around a punishing biological scorecard, likely to grow through premium niches owned by conservatively financed integrators rather than a public champion [7]. And other animal production is a drawer of four independent bets, only one of which (lab animals) is genuinely investable in public markets [6]. The shared wildcards — disease (above all H5N1), feed costs, trade policy, and antitrust — could move supply and prices sharply across several children at once. A durable thesis at this level should not rest on any single child's current cycle: the best operators in any of the six are distinguished by low-cost feed or forage, dependable biosecurity, strong genetics, disciplined working capital, and reliable market access — and, for public-market capital, by the hard fact that the subsector is private at the core and reachable only around the edges.
