Hog and Pig Farming (NAICS 1122)

A Histometrics industry primer for public-market and private investors.

1. Overview

Hog and pig farming is the business of breeding and raising pigs for sale — as young weaned pigs, feeder pigs, or market-weight hogs bound almost entirely for pork. It is one of the largest single livestock sectors in U.S. agriculture: farmers sold roughly $36.4 billion of hogs in the 2022 Census of Agriculture, about 6.7% of all U.S. farm product sales, with a national herd steadily in the low-to-mid 70-million-head range [3][6].

At this level of the classification, 1122 — Hog and Pig Farming is a North American Industry Classification System (NAICS) industry group (the four-digit level). It is a real-economy, food-supply business: a high-volume, low-margin, deeply cyclical commodity. Producers make money on the spread between what a market hog sells for and the cost of the feed (corn and soybean meal) and piglets that went into it — a spread that swings from profitable to loss-making across a multi-year "pig cycle." The industry is unusually concentrated and vertically integrated, so a handful of large companies shape the economics for tens of thousands of contract farmers.

2. What's inside — and why this level equals its one child

NAICS is a nested system: each four-digit industry group sits above five-digit industries, which in turn sit above six-digit national industries. In this case the industry group 1122 contains exactly one child, which carries the same name and definition:

• 11221 — Hog and Pig Farming

Because 1122 has a single child (and that child, 11221, itself has a single six-digit child, 112210), all three levels are effectively identical — every hog and pig farm counted at 1122 is also counted at 11221 and 112210, with no aggregation of differently-defined sub-industries in between. This primer is therefore a short pass-through. The full detail — production chain, ownership mix, investable universe, margin mechanics, demand drivers, regulation, and risks — lives in the 11221 (and 112210) primer, which you should read for anything beyond the summary below.

For orientation, the code covers farm production only — farrow-to-finish, farrow-to-wean, nursery, and finishing operations [2]. The high-value downstream steps (slaughtering, packing, branded meat) sit in separate codes such as 311611 and 311612, even though the same companies (Smithfield, Seaboard, Tyson, JBS) span both farm and plant [2].

3. Size (this level's figures)

We hold no ingested federal business-statistics figures specific to NAICS 1122 in our ground-truth file for this node — no establishment count, employment, payroll, or receipts total. The figures below are drawn from the cited USDA and Census sources at the identical child level (11221 / 112210); because the levels coincide, they describe 1122 as well.

Undercount caveat. Standard federal business statistics badly undercount this industry. The Census Bureau's County Business Patterns excludes crop and animal production (all of NAICS 112), and its Nonemployer Statistics likewise exclude animal production [9][10]. Employer-based datasets therefore miss most of this sector — tiny, family-run, nonemployer, and contract-growing operations especially, and ownership here is dominated by small and individual/family operators. The authoritative count is instead the U.S. Department of Agriculture (USDA) Census of Agriculture, designed as a complete count of farms.

Two "how big" numbers differ by design: the Census reports the gross sales value of hogs ($36.4B, which double-counts pigs sold between farms), while USDA Economic Research Service (ERS) cash receipts ($27–31B) is a net farm-income measure. Both are correct; they answer different questions. Neither is the same as revenue reported by companies classified under this code — the single U.S. Small Business Administration (SBA) size standard of $4 million in average annual receipts is a small-business definition for federal programs and lending, not a measure of industry revenue [1].

4. Investable universe — where value concentrates

Because 1122 contains only 11221 (and one six-digit code below it), there is no split of value across sibling children — all of it sits in the one industry. Within that industry, value is heavily concentrated in a small number of large, vertically integrated systems rather than spread evenly across the ~60,000 farms. The 2022 Census reported that 93% of specialized hog and pig farms were family farms, yet 75% of the national hog inventory sat on operations with at least 5,000 head [4] — "family farm" does not mean small-scale. Roughly two-thirds of U.S. hogs are under contractor/integrator control rather than sold at arm's length [4]. The mental model is a small number of integrators orchestrating a large network of contract barns. See the 11221 primer for the full ownership breakdown and the listed-company map.

5. How the money works

Integrated producers earn a crush-style margin: the value of the finished hog minus the cost of the piglet and the feed to grow it. Feed is the swing factor — about 48% of total production expenses across specialized hog farms in the 2022 Census, and 60–70% of operating cost in a farrow-to-finish budget, dominated by corn and soybean meal [4][17]. Because per-head margins are thin, profit turns on volume, feed conversion, herd health, and plant utilization. Contract growers trade price upside for a stable per-head or per-space fee. Exports are a critical margin lever: the U.S. shipped a record $8.63 billion of pork in 2024, and variety meats that command little value domestically sell profitably abroad [25]. The 11221 primer covers price benchmarks, the pig cycle, and integrator economics in full.

6. Demand drivers

Demand drivers are identical to the child level: domestic pork consumption (steady but mature, competing with cheaper chicken and pricier beef); exports (the marginal driver — roughly a quarter of U.S. pork, led by Mexico and Japan, sensitive to trade policy and currency) [7][25]; feed costs as an inverse driver of supply [16]; foreign disease outbreaks such as African Swine Fever (ASF) abroad, which can surge U.S. export demand; and higher-value programs (antibiotic-free, welfare-certified). See 11221 for detail.

---

7. Regulation

The regulatory burden — animal-welfare, environmental, animal-health, food-safety, and market-conduct rules — applies identically at this level. The headline items: state animal-welfare sales laws (California Proposition 12, upheld by the U.S. Supreme Court in May 2023, and Massachusetts Question 3) that effectively set national sow-housing standards and split the market into compliant and non-compliant pork [19][20]; Concentrated Animal Feeding Operation (CAFO) rules under the Environmental Protection Agency (EPA) and Clean Water Act [21]; USDA Food Safety and Inspection Service (FSIS) slaughter inspection [22]; the Packers and Stockyards Act governing livestock purchasing [23]; and USDA Animal and Plant Health Inspection Service (APHIS) disease policy, with ASF as the sector's tail regulatory risk [24]. Full treatment is in the 11221 primer.

8. Consolidation

This is a consolidated, vertically integrated, low-margin industry. USDA ERS reports the number of U.S. farms with hogs has fallen more than 70% since 1990 as operations grew larger and more specialized [7]; farm numbers fell ~13% just from 2017 to 2022 even as output rose [4]. Slaughter is a top-three oligopoly (Smithfield ~25%, JBS ~18%, Tyson ~16% in 2020, roughly 60% combined) that has drawn antitrust and price-fixing scrutiny [17]. Notably, the biggest players are now partly deconsolidating the farming piece — Smithfield deeding sows back to independent growers — a judgment that owning the volatile hog-raising step is less attractive than buying hogs and focusing on branded, packaged meat [25].

---

9. Risks

The risk profile is the child's: disease (endemic Porcine Reproductive and Respiratory Syndrome, or PRRS; a potential U.S. ASF detection as the dominant tail risk) [24][24]; feed-price volatility [17]; pig-cycle oversupply and whole-year losses (as in 2023) ; processing bottlenecks (a farm needs a buyer and a slaughter slot); trade dependence with ~25% of output exported [25]; regulatory-cost / welfare risk from Prop 12 / Question 3-style laws [19][20]; environmental and social-license exposure (manure, odor, litigation); buyer concentration and antitrust scrutiny [17]; and financial and succession risk on debt-heavy private farms. See 11221 for the full discussion.

10. How to invest and outlook

Because 1122 equals its one child, the level is investable exactly the same way as 11221 — there is no listed pure-play hog farmer.

Public routes. Most direct is Smithfield Foods (Nasdaq: SFD), the only large listed company whose identity is pork/hogs — though WH Group still controls ~91%, so float is thin [12]. More concentrated but diluted: Seaboard (NYSE American: SEB) [13]. Diversified/global: Tyson (NYSE: TSN), JBS (NYSE: JBS), Hormel (NYSE: HRL), and WH Group (HKEX: 0288) — pork exposure blended with other proteins, branded foods, or foreign operations [14][15][16]. Treat all as commodity-cyclical equities: value on mid-cycle earnings, feed spreads, and export access, not a single year.

Private routes. Direct farm equity, senior lending, barn/farmland finance, producer-owned processors, feed mills, veterinary/genetics businesses, logistics, or manure-to-energy projects — where the genuine farm-level economics mostly sit. The $4M SBA receipts line marks the "small business" boundary [1].

Near-term outlook. USDA's July 2026 forecast calls for just under 28 billion pounds of U.S. pork production in 2026 (up 1.4%), 2026 exports of 7.2 billion pounds (up 3.8%), and average hog prices of $66.63/cwt in 2026 [8]. Watch cheap feed (supports margins), Mexico/Japan export strength and any China swing (sets the marginal price), Prop 12 build-out, herd discipline as majors trim sows, and ASF vigilance (the dominant downside) [8][25][17][19][24].

Bottom line. Because 1122 equals 11221 (and 112210), the investment case is one and the same: a mature, cyclical, export-sensitive commodity industry, consolidating at the farm level even as its biggest players shift risk toward packaged meats — investable mainly through the integrators, with the genuine farming economics largely private.
