Other Animal Food Manufacturing (United States)

NAICS 2022 code 311119 — the industry that makes feed for livestock, poultry, horses, fish, and wild birds. Everything animals eat except dog and cat food.

---

1. Overview

Other Animal Food Manufacturing covers the mills and plants that turn raw commodities — corn, soybean meal, grain byproducts, vitamins, and minerals — into finished feed for farm and specialty animals: cattle, hogs, chickens, turkeys, horses, farmed fish and shrimp, gamebirds, and backyard flocks, plus wild-bird seed. It is the link between the grain elevator and the meat case: the U.S. Department of Agriculture and industry groups estimate feed is 50% to 70% of the cost of producing meat, milk, and eggs at the farm gate, so this industry sits underneath nearly the entire animal-protein economy.[2][3]

By the federal government's narrow definition, the industry shipped about $47.3 billion of product in 2022 across roughly 890 firms and 1,460 establishments, employing about 31,600 people with a payroll of $1.95 billion.[1] By 2023, establishment count reached 1,463 and employment 34,400 with payroll of $2.27 billion.[1] But those figures understate how much animal feed the country actually makes, because much of it is produced on-farm or inside vertically integrated meat companies and never counted here (see Section 3).

Why an investor cares. Feed is a defensive, staple-linked business — animals eat in booms and recessions — but it is also thin-margin and cyclical, tied to grain prices and to the size of the national herd and flock. There is no large pure-play public "feed manufacturer" to buy. Investors get exposure two ways: through public diversified agribusiness and specialty-ingredient companies (ADM, Balchem, Phibro, Central Garden & Pet) that own feed and feed-additive operations, and through private channels — the giants that dominate the industry (Cargill, the farmer cooperative behind Purina, Alltech, Nutreco) are privately held or member-owned, and the highest-growth value increasingly sits in specialty nutrition rather than bulk feed.

2. What it is and how it's structured

In scope (311119). Complete feeds and feed concentrates for cattle, swine, and poultry; mineral and vitamin supplements; premixes and concentrates; specialty feeds for horses, aquaculture (fish and shrimp), gamebirds and other species; alfalfa meal; and wild-bird feed.[2] Products range from cheap bulk commodity rations to branded, science-heavy specialty nutrition.

Explicitly excluded — and where those activities are counted instead:

• Dog and cat food → NAICS 311111 (a separate, much larger consumer-branded industry; Census reported $27.5 billion in shipments for 2022).[1][3]
• Flour milling → NAICS 311211.
• Soybean and other oilseed processing → NAICS 311224 — this makes soybean meal, the industry's key protein ingredient, so it is adjacent and upstream.
• Animal slaughtering and rendering → NAICS 31161 — rendering produces feed-grade fats and animal proteins (another upstream ingredient).
• Animal drugs, vitamins, and medicines → pharmaceutical manufacturing (NAICS 32541) — even when they end up mixed into feed.[2]

How a mill works. A conventional mill receives bulk grain, oilseed meal, fats, minerals and byproducts; samples and stores them; grinds coarse ingredients; meters each ingredient against a nutritionist's formula; and mixes the batch to label specifications. Feed may then be sold as mash or steam-conditioned, pelleted, cooled, crumbled and screened. Quality control matters because poor mixing can create nutrient deficiencies, violate a medicated-feed label, or kill animals; Kansas State describes mixing uniformity as both an operating requirement and an FDA compliance issue.[4]

Ownership mix. Three overlapping structures coexist:

1. Commercial ("merchant") feed mills that sell feed to farmers — the classic business counted in this code, from national brands to single-county mills.
2. Farmer cooperatives — member-owned. The largest branded U.S. livestock-feed name, Purina Animal Nutrition, is owned by the Land O'Lakes cooperative.[15]
3. Captive mills inside integrated meat companies — poultry and hog integrators (Tyson, Pilgrim's Pride, Perdue, Smithfield) run their own feed mills to supply their contract growers. This feed is made in enormous volumes but is often classified under the parent's meat business, not here.

Feed economics are intensely local: finished bulk feed is heavy and cheap per ton, so it can't travel far before freight eats the margin. That keeps hundreds of regional and local mills alive alongside the global majors.

3. How big it is

Federal statistics for NAICS 311119 (the specific, narrow definition):

A telling ratio: about $1.37 million of shipments per employee.[1] That is very high for manufacturing and tells you what this business is — a materials business, not a labor business. The 2022 Economic Census reports $35.3 billion of materials consumed, equal to 74.6% of shipment value, while payroll was just 4.1%.[1] Purchased ingredients (grain, meal, byproducts, micro-ingredients) are the overwhelming majority of cost and largely pass straight through to the customer; the plant grinds, mixes, and pellets with relatively little labor. Year-end industry inventory was $2.95 billion, demonstrating meaningful working-capital and commodity exposure.[1]

What mills buy. The largest disclosed material categories for 2022:

• Corn: $8.2 billion
• Soybean-processing products: $4.6 billion
• Other grains: $2.2 billion
• Rendered animal products: $1.4 billion
• Fats and oils: $1.3 billion
• Flour and other grain-mill products: $1.1 billion
• Wheat: $0.6 billion[1]

The undercount is large and important. The $47.3 billion above counts only merchant manufacturing establishments in this code. It leaves out two huge pools of feed:

• On-farm mixing. Many farmers buy commodity ingredients and mix their own rations on-site; that feed is never sold and never counted as "manufacturing."
• Captive integrator mills classified with their poultry- or hog-processing parents rather than under 311119.

Include everything and the picture is far bigger. USDA's broader measure of farm feed expenditure was $83.6 billion in 2022, equal to 18.5% of all farm production expenses — but that includes feed bought from industries outside 311119.[5] The American Feed Industry Association (AFIA) estimates U.S. animals consume roughly 284 million tons of feed a year, and pegs the total U.S. animal-food industry (livestock feed plus pet food) at about $267 billion in sales for 2023.[3] Private market-research estimates of the U.S. compound-feed market run from roughly $114 billion to $270 billion depending on scope.[6] The gap between those numbers and the federal $47.3 billion is scope (some include pet food and on-farm/captive volume) plus the genuine undercount. For the specific merchant industry defined by 311119, treat ~$47 billion as the anchor and read the larger figures as the whole feed ecosystem around it.

4. The investable universe

There is no large, pure-play public "other animal food" manufacturer. The biggest producers are private or cooperative-owned. Public exposure comes through diversified agribusinesses and specialty-nutrition companies, plus adjacent ingredient suppliers.

Public companies (feed and feed-ingredient exposure)

Animal-health names Zoetis (ZTS) and Elanco (ELAN) sell drugs and additives that go into feed but are pharmaceutical companies, not feed makers. Tractor Supply (TSCO) and farm-and-ranch retailers sell feed but don't manufacture it. Tyson (TSN), Seaboard (SEB), and Cal-Maine (CALM) provide captive-feed exposure; for these companies, feed is primarily an input cost, so lower feed prices normally help consolidated margins even if they reduce the nominal value of feed manufactured.

Private and cooperative owners (where most of the industry actually sits)

• Cargill (private) — the largest U.S. and North American feed producer, with 211 feed mills; brands include Nutrena, Provimi, and Diamond V.[15]
• Land O'Lakes / Purina Animal Nutrition (farmer cooperative) — the leading branded U.S. livestock-feed name.[15]
• Wayne-Sanderson Farms (private) — formed by Cargill and Continental Grain in 2022.[20]
• Nutreco — Trouw Nutrition and Skretting (aquafeed); owned by SHV Holdings, a private Dutch group.
• Alltech (private, Kentucky) — feed additives and nutrition; operates 77 mills.[15]
• Kemin Industries (private, Iowa) — feed ingredients and additives.
• Kent Corporation / Kent Nutrition Group (private) — Blue Seal, Sentinel horse feeds.
• Manna Pro (private-equity owned) — backyard-poultry and hobby-livestock feed.
• J.D. Heiskell, Wilbur-Ellis, Perdue AgriBusiness and many regional cooperatives and mills.
• Vertically integrated meat companies running captive feed mills: Tyson, Pilgrim's Pride (JBS), Perdue, Smithfield (WH Group), Koch Foods.

5. How the money works

Feed manufacturing is a commodity conversion (toll) business with a value-added specialty layer on top. Owners make money two different ways:

A) Bulk / commodity feed — a spread-and-volume game. The mill buys ingredients (corn, soybean meal, distillers grains, plus micro-ingredients), then grinds, mixes, and pellets them into finished rations sold by the ton. Because ingredients are the vast majority of cost and largely pass through to the buyer, the number that matters is not the headline price of feed but the spread per ton — the margin over ingredient and conversion (energy, labor, freight) cost — multiplied by tons sold. Gross margins are thin, so the levers are:

• Capacity utilization of the mill (fixed costs spread over more tons);
• Ingredient buying and formulation — least-cost formulation software swaps ingredients (e.g., cheap distillers grains for corn and soybean meal) to hit a nutrition spec at the lowest cost;
• Freight radius — bulk feed is uneconomic to ship far, so pricing power is local;
• Pass-through timing — a lag between rising ingredient costs and repricing can squeeze margin.

B) Value-added specialty nutrition — where the profit and the public-market value are. Premixes, concentrates, medicated feed additives, vitamins and amino acids, encapsulated minerals, enzymes, probiotics, gut-health products, young-animal and aquaculture nutrition. These are branded, patent- and research-driven, sold on performance (better feed-conversion, growth, immunity) rather than on price per ton — so they carry much higher margins and are less commoditized. This is the layer ADM's Nutrition segment, Balchem, Phibro, Alltech, and Kemin compete in, and it's why the investable public names skew toward additives and ingredients rather than bulk milling.

The customer's math drives everything. A farmer's key metric is the feed-conversion ratio (pounds of feed per pound of gain) and total feed cost, because feed is 50–70% of their production cost.[2] When grain is cheap and meat prices are firm, farmers expand herds and buy more feed; when feed costs spike, they cull. So the manufacturer's volume is tied to its customers' margins, and per-ton spreads are more stable than the wild swings in commodity prices themselves.

Cyclicality. Volume follows livestock cycles of very different lengths — USDA notes the cattle cycle commonly runs eight to twelve years, the hog cycle months, broiler chickens just weeks.[7] That means poultry feed demand adjusts fast while cattle-feed demand turns slowly.

Profitability. Census does not publish an industrywide EBITDA or operating margin. ADM provides a useful company observation, though not an industry benchmark: its global Animal Nutrition subsegment generated $3.3 billion of 2025 revenue and $98 million of operating profit, a calculated 2.9% margin. Results improved from $59 million of operating profit in 2024 because of cost optimization, a richer feed-additive mix, and lower raw-material costs — but ADM's subsegment includes products and geographies outside U.S. 311119.[11]

---

6. What drives demand

• The size of the U.S. herd and flock. More animals, more feed. This is the master variable, and right now the segments diverge sharply:
• Cattle are at a historic low — USDA counted 86.2 million head as of January 1, 2026, including 13.8 million on feed (down 3% year-over-year), the smallest herd since 1951 after seven straight years of contraction. That is a real headwind for cattle-feed volume, and because the cattle cycle is slow, recovery takes years.[7][8]
• Broiler chickens are projected to hit record production for years, driven by cheap, efficient feed conversion and firm chicken demand — a tailwind for poultry feed. From 2015 through 2024, U.S. broiler production increased 17.3% and table-egg production 10.3%, while turkey production declined 9.0%.[21]
• Egg layers were hit hard by highly pathogenic avian influenza (HPAI), which killed more than 60 million table-egg layers between late 2024 and spring 2025, cutting layer-feed demand.[7]
• Hogs are relatively steady; aquaculture feed is the fastest-growing niche globally.[17]
• Grain and protein-meal prices. Cheap corn and soybean meal (corn around $4.00–$4.25/bushel and soybean meal $275–$325/ton in 2025) lower farmers' costs and encourage herd retention and expansion — supportive for feed volume, even as cheaper ingredients can lower the dollar value of feed sold.[9]
• Aggregate feeding demand. USDA forecast record U.S. corn feed-and-residual use of 6.2 billion bushels for 2025/26 — a grain-balance measure, not manufactured-feed tonnage, but indicative of strong overall feeding activity.[22]
• Meat, dairy, and egg demand — domestic consumption and exports pull animal protein through the system, and feed follows. USDA's long-term baseline projects red-meat and poultry disappearance increasing from 226 pounds per person in 2027 to 241 pounds in 2035, with most of the gain attributable to broilers.[23]
• Byproduct substitute supply. Ethanol plants produce distillers dried grains with solubles (DDGS) — about 17–18 pounds per bushel of corn — a protein-and-energy feed ingredient that substitutes for corn and soybean meal. DDGS availability (tied to ethanol/biofuel policy) directly affects how much compound feed farmers need to buy.[16]
• Circular-economy sourcing. Feed mills provide an outlet for food-processing co-products — distillers' grains, bakery residuals, whey, and other materials. One AFIA example reports a liquid-feed producer sourcing 85–90% of its ingredients from other industries.[24]
• Consumer and hobby demand — backyard chickens, horses, and wild-bird feeding are retail-driven and less cyclical, sold through farm stores (Central Garden & Pet, Purina, Manna Pro, Tractor Supply).
• The antibiotic-free shift — as medicated feed is restricted (Section 7), demand grows for non-antibiotic performance products (probiotics, enzymes, organic acids), moving spend toward the specialty layer.

---

7. Regulation

Animal feed is legally "food" and is regulated primarily by the U.S. Food and Drug Administration's Center for Veterinary Medicine, with a state-level overlay.

• FSMA — the Food Safety Modernization Act. The Preventive Controls for Animal Food rule (21 CFR Part 507) requires feed facilities to register with the FDA, follow current Good Manufacturing Practices, conduct hazard analysis, implement risk-based controls, and maintain monitoring, corrective-action, verification, and recordkeeping systems. FSMA shifted the industry from reacting to contamination toward preventing it — and raised the compliance cost of running a mill.[10]
• AAFCO — the Association of American Feed Control Officials. Not a government agency; it's a voluntary body of state and federal feed-control officials that writes model feed regulations, ingredient definitions, and labeling standards that states then adopt. In practice, a feed ingredient must be AAFCO-defined or FDA-approved to be legally sold.[10]
• Medicated feed and the Veterinary Feed Directive (VFD). Feed containing FDA-approved animal drugs is "medicated feed," and mills that make it need an FDA license and drug-establishment registration. Since 2017, the VFD rule requires a licensed veterinarian's written order to use medically important antibiotics in feed — moving them off over-the-counter status to fight antimicrobial resistance. Subsequent FDA guidance moved the remaining over-the-counter antibiotics to prescription-only. The net effect is a structural shrink in routine medicated feed and a shift toward alternatives.[10][25]
• The ruminant feed ban. To prevent bovine spongiform encephalopathy ("mad cow disease"), the FDA prohibits most mammalian protein in cattle and other ruminant feed. Tallow containing more than 0.15% insoluble impurities is restricted, making ingredient segregation, sequencing, and cleanout commercially important — a lasting constraint on how rendered animal proteins can be used.[26]
• OSHA grain-handling standard. OSHA's grain-handling standard (29 CFR 1910.272) expressly covers feed mills. Grain dust can explode; workers face bin engulfment, falls, machinery injuries, and respiratory exposure.[27]
• State feed-control programs. States require product registration, charge tonnage/inspection fees, and enforce labeling — a patchwork that adds administrative cost for multi-state sellers.

8. Competitive dynamics and consolidation

On paper the industry looks fragmented and unconcentrated. Census-based research from Iowa State reports a 2022 four-firm concentration ratio of 23.3% and a Herfindahl-Hirschman Index (HHI) of 218.9 — well below the 1,500 threshold economists treat as "unconcentrated."[28] That reflects the local freight economics that keep hundreds of regional mills viable.

But the national numbers hide the real structure:

• A few giants tower over a long tail. Cargill, the Land O'Lakes/Purina cooperative, and ADM operate the most feed mills in North America; Cargill alone runs 211 mills, ADM 82, and Alltech 77.[15] They coexist with many small local players precisely because bulk feed doesn't travel.
• Vertical integration removes volume from the merchant market. The largest poultry and hog companies make their own feed in captive mills, so a big slice of "feed manufacturing" never competes on the open market — and doesn't fully show up in this industry's statistics.
• Cooperatives are structurally central, not a fringe — the leading branded livestock feed is member-owned.
• Consolidation is steady, and concentrated in specialty. The bulk-milling map changes slowly, but feed additives and specialty nutrition see active mergers and acquisitions: Cargill's roll-up of Provimi and Diamond V, ADM's build-out of animal nutrition (Wisium, Neovia), and Phibro's $350 million purchase of Zoetis's medicated-feed-additive portfolio in 2024 are examples of value migrating up the chain.[13][15] Global majors (Charoen Pokphand, New Hope, ForFarmers, De Heus) round out a worldwide field.

---

9. Risks

• Input-cost volatility. Corn, soybean meal, energy, and freight are the business. When ingredient costs spike faster than a mill can reprice, per-ton margin gets squeezed — the classic pass-through-lag risk.
• Livestock cyclicality. The cattle herd at a 70-year low compresses ruminant-feed volume, and slow biological cycles mean recovery is measured in years, not quarters.[7][8]
• Animal-disease shocks. HPAI (avian influenza) has already erased tens of millions of layers and their feed demand; African swine fever, though not established in the U.S., is a tail risk to hog-feed volume. Disease can vaporize demand in a region overnight. AFIA identifies ingredients, receiving, internal cross-contamination, delivery vehicles, and personnel as potential disease pathways.[7][29]
• Regulatory tightening. FSMA compliance cost, the ongoing squeeze on medicated feed (VFD and prescription-only antibiotics), feed-additive approval timelines, and the ruminant protein ban all constrain or add cost.[10][25]
• Food-safety and recall liability. Mycotoxins, Salmonella, chemical residues, misformulation, and drug carryover can trigger recalls, animal losses, legal exposure, and reputational damage.
• Thin margins with limited scale leverage. Local freight economics cap how much national scale helps in bulk feed, while mills are capital-intensive.
• Ingredient and trade exposure. Many micro-ingredients (vitamins, amino acids) are imported, largely from China — a supply-chain and tariff risk — and feed/ingredient exports (about $11.6 billion in 2024) are exposed to trade disputes.[3]
• Operational safety. OSHA's grain-handling standard applies; grain dust can explode, and workers face bin engulfment, falls, machinery injuries, and respiratory exposure.[27]
• Rural labor availability. Mills require reliable maintenance technicians, quality personnel, nutritionists, operators, and drivers, often on continuous schedules.
• Technological substitution. Precision nutrition, alternative proteins (insect and single-cell), and shifts in DDGS supply tied to biofuel policy can reshape ingredient demand.

10. How to invest, and the outlook

Public-market routes. Because there's no large pure-play, investors typically get exposure through:

• Diversified agribusiness — ADM (NYSE: ADM), whose Animal Nutrition business (~$3.3 billion revenue in 2025) rides feed volumes and additive demand, though it's a small slice of an ~$85 billion company.[11]
• Specialty feed-nutrition and additives — Balchem (Nasdaq: BCPC) and Phibro Animal Health (Nasdaq: PAHC) are the closest things to focused public plays on the higher-margin nutrition layer.[12][13]
• Consumer/hobby feed — Central Garden & Pet (Nasdaq: CENT/CENTA) for wild-bird and small-animal feed.[14]
• Upstream ingredient suppliers — Bunge (NYSE: BG) for oilseed meal and Darling Ingredients (NYSE: DAR) for feed-grade fats and proteins.
• Captive-feed exposure — Tyson (NYSE: TSN), Smithfield (Nasdaq: SFD), Seaboard (NYSE: SEB), and Cal-Maine (Nasdaq: CALM) operate captive mills; for these companies, feed is primarily an input cost.[19]

These carry the usual public-equity metrics (share price, dividend yield, earnings multiples), but note that in every case feed is one segment of a broader company — you are buying diversified agribusiness or specialty chemistry, not a bet on feed alone.

Private routes. The largest and most direct ownership of this industry is private: Cargill, the Land O'Lakes/Purina cooperative, Alltech, Kemin, Kent, and Nutreco (SHV). Private and institutional investors participate through private equity in regional mills and specialty brands (as with Manna Pro), through farmer-cooperative membership, and through venture and growth capital in feed-technology and alternative-ingredient startups (enzymes, probiotics, methane-reducing additives, insect and single-cell protein). Diligence should separate externally sold merchant tonnage from captive tonnage; manufactured product from commodity resale; complete feed from higher-margin premixes and additives; and dog/cat products from the actual 311119 perimeter.

Near-term drivers (forward-looking).

• Cheap grain is supportive. With corn and soybean meal below long-run averages into 2026, farmers' feed costs are low, which encourages herd retention and eventual expansion — constructive for feed volume over the medium term, even if it trims nominal feed sales value.[9]
• The herd picture is split. Record broiler production is a tailwind for poultry feed; the historically small cattle herd is a multi-year headwind for ruminant feed; aquafeed is the fastest-growing niche.[7][17]
• Long-term protein demand rising. USDA projects per-capita meat and poultry consumption increasing from 226 to 241 pounds between 2027 and 2035, supportive for feed demand — though genetics and precision nutrition continue to reduce feed required per pound of meat.[23]
• Value keeps migrating to specialty. Antibiotic restrictions, demand for gut-health and performance additives, precision nutrition, and interest in feed additives that cut cattle methane emissions all push the profit pool toward the research-driven specialty layer — the part of the industry public investors can most cleanly own.
• Consolidation continues, concentrated in additives and nutrition rather than bulk milling.

The bottom line: a large, defensive, staple-linked industry that is bigger than its official statistics suggest, but structurally low-margin, cyclical, and mostly privately held at the bulk end — with the investable upside concentrated in the specialty-nutrition and feed-additive companies stacked on top of it.
