πŸ– Pigs: Meat, Lard and Leftovers

How to keep pigs with no feed store, no vet and no fridge: choosing lard, bacon and pasture breeds, fences that hold pigs when the charger is dead, rooting, feeding on Pacific Northwest pasture and on grain the pigs harvest themselves, acorns and kitchen scraps, what never to feed, shade and water in our hot summers, breeding, farrowing and piglets, health with no vet, butchering day in cold weather, rendering lard, keeping trichinosis and tapeworm out of the family, and why a pig must never get loose. Curing and smoking are in the Preserving Food guide. The pig books are in Animals\Cattle-Horses-Pigs (USDA Pasture and Grain Crops for Hogs in the Pacific Northwest, Swine Production and Pork Slaughtering, OSU Care of New Feeder Pigs, Slaughter and Preservation of Meat), with Pork on the Farm in Homestead-Skills\Food-Crafts-Tools, lard in Food-From-Scratch\Wild-and-Local-Staples, smokehouse and hoist plans in Food-Storage\Curing-Smoking, no-vet medicine and the diseases people catch from pigs in Animals\Veterinary, and poisonous plants in Wild-Plants. The main CVM book, Raising Healthy Pigs, has photos but no text the search tool can read, so this guide does not quote it.

The short version


πŸ– Choosing pigs: lard, bacon and pasture breeds

The hog is "the most valuable farm animal in utilizing farm wastes" (FB 1437, p. 4): scraps, whey, gleanings, acorns and culls become meat and fat. With no store oil, lard is the household's cooking fat, so choose for fat as well as meat.

Type Built like Best fed on Breeds named in the books
Lard Short-legged, thick, compact; small litters Corn and other fattening grain Poland China: black with six white points, 600–1,000 lb grown, fast-gaining, good survival (Peace Corps, pp. 280–281; p. 284)
Bacon Long, lean, muscled Peas, wheat, barley, oats, rye, dairy by-products and roots: what our valley grows Landrace: long, prolific, efficient. Yorkshire: good mothers, large litters, forage well, but do poorly with little care (pp. 281, 284)
Meat (in between) Large, fast-growing, hungry Grain plus protein Duroc: red, litters survive well, sows "fierce in the defense of their young." Hampshire: white belt, sows raise a high share of their pigs; smaller, slower (p. 284)

Pasture pigs: a breed "selected genetically for production" needs "high quality feed, a disease-free environment, good housing" (Peace Corps, p. 280). On pasture and leftovers pick hardy crossbreds or old grazing breeds that mother well, such as Berkshire, Tamworth, Large Black or the small Kunekune, over modern indoor lines (rule of thumb). Crosses give bigger litters, more pigs living and faster growth (p. 282). Sunburn is a trait to select against (p. 281): under our July sun, dark-skinned pigs fare better (rule of thumb).

Buying: "start with only a few sows," of one breed and herd, ideally already bred. A good sow lets you into her pen any time, has legs long enough to keep her udder off the ground and at least six teats in each row; keep no pigs from a cross or nervous sow (FB 1437, pp. 5–7). Buy only from herds you know are healthy. Feeder pigs (weaned pigs raised for meat) need a clean, dry, draft-free pen ready; ask what they ate and change feed slowly (OSU EM 9271, pp. 1, 3).

🏠 Pens, fences and rooting

Room per pig under cover: sows, gilts and boars 15–20 sq ft; sow and litter 50–65; weaners to 75 lb 5–6; 75–125 lb 6–7; 125–200 lb 8–10; build near the house and the feed, proof against predators (Peace Corps, p. 288). A 50-lb pig is comfortable at 70–82 Β°F, a 215-lb one at 50–75 Β°F, and Oregon nights chill young pigs "through the month of May": bed deep with straw (OSU EM 9271, pp. 1–2) and never let pigs sleep on damp bedding (FB 1437, p. 34). A roof on posts with straw-bale walls is a winter house; take the bales out and it is a summer shade (FB 1437, p. 38). Feed in a V-shaped trough with slats across the top, 1–2 ft per pig (pigs fed on the ground get more worms), and water in a heavy concrete bowl they can't tip (Peace Corps, pp. 290–291). Dig or plow pig lots twice a year and sow them to pasture (FB 1437, p. 37): worm eggs live years in damp soil but die in weeks of sun (No Animal Doctor, p. 347).

Fences that hold pigs

Fence "hog tight" with woven wire: about 26 in high on a big field with one barbed strand at the bottom, just above the ground, and 32–36 in around a small pen, where pigs push harder. "Probably 90 percent" of a woven-wire fence's strength is in well-braced corner posts (FB 1437, p. 21). Pigs root under woven wire, so run "one or two electric fence wires near the bottom" (OSU EM 9271, p. 5) on the pig side, where a snout meets them first: about 6–8 in and 12–16 in up (rule of thumb).

End view of a hog fence: woven wire on the pig side of the post, 32–36 inches high, with a barbed strand at the ground or two hot wires on offsets about 6–8 and 12–16 inches up, and a pig nosing the lower wire Woven wire with low hot wires on the pig side; in a dry summer the lower wire becomes the ground wire (FB 1437, p. 21; OSU EM 9271, p. 5) (a diagram drawn for this guide).

Electric wire with no power from the grid

Rooting: the problem and the plow

Pigs root hardest in wet ground (FB 599, p. 3), and west of the Cascades winter tramping "puddles" (packs and ruins) wet soil: take them off pasture in heavy rain, except on sandy soil or tight sod (p. 12). English ryegrass sod "stands tramping well" (p. 15), and straw spread first protects heavy soil (p. 17). Keep the winter lot on your best-drained, gravelly ground (rule of thumb). Ringed hogs (rings in the top of the snout) can't dig tubers (same page); buy rings and a ringer now (rule of thumb). Rooting is also free plowing: hogs work stalks into the soil and spread their droppings evenly (p. 7). Turn pigs onto a finished garden in early fall, then move them before the mud (rule of thumb).

Predators, and pigs as a danger

"Store livestock food in a secure place" (ODFW, p. 2), and shelter animals at night against cougars (ODFW, p. 2): a night pen near the house and carrying off carcasses are rated effective against lions, bears and coyotes (UC ANR 8598, p. 5). Bears raid pig pens and take piglets (rule of thumb). Sows with piglets and boars "may attack and bite" (No Animal Doctor, p. 47): carry a board to hold between you, never turn your back on a boar, keep children out of the pen, and keep pigs from chickens, which they kill (rule of thumb).

🌾 Feeding with no feed store

Pasture alone is not enough for growing pigs: they get "big bellied, and thin in flesh or stunted," though dry sows can hold condition on good pasture (FB 599, p. 4). On pasture feed grain at about 2–3% of live weight a day, or 1% for a light ration, then fatten on all they clean up three times a day (p. 5); a growing pig on abundant pasture gets 1–2 lb of grain a day (FB 1437, p. 15). Change feed slowly, a quarter at a time over at least a week (p. 10).

Pasture and crops for hogs in the Pacific Northwest

USDA Farmers' Bulletin 599 was written for Washington, Oregon and Idaho; in western Oregon it finds hog pasture "throughout the entire year" (FB 599, pp. 2, 12–15):

Crop Sow Graze Hogs per acre
Red clover (drained soil), alsike (wet) A year ahead April–November; best April–June, fades in drought 8–16
Alfalfa A year ahead April–November; "highly successful in the Umpqua and Rogue River Valleys on irrigated and subirrigated land" 8–16
Rape in hoed rows April 1, 15 and 30 June–November; green all summer if cultivated 8–14
Vetch with wheat or oats In corn in July, or on stubble in early fall October/November–April 5–8
English ryegrass, 10–15 lb seed per acre Spring or fall, with grain Early fall to the next July 5–14
Winter wheat September–October February–April 8–16

Split pasture in two or more and move hogs every 7–10 days, turning them in when clover or alfalfa is 3–4 in high and rape, kale or vetch 8–10 in (p. 3); legume pasture means less grain (p. 6). Never plan "just enough": an acre carries 5–15 hogs of 100 lb (FB 1437, p. 19). Here grass and clover quit in July unless watered, so plan summer around grain to hog off (rule of thumb); serpentine ground grows poor, low-calcium pasture (NRCS, p. 49).

Hogging down grain, peas and corn

"Hogging off" means turning hogs into a ripe field to harvest it themselves: no threshing or hauling, and the hogs need only "water, shade, and salt" (FB 599, pp. 6–7). In western Oregon: beardless barley July 1–20, soft club winter wheat July 10–August 10, field peas July 25–October 1, corn (planted April 20–May 10) from mid-September, earlier in the Rogue Valley (pp. 15–16). Bearded barley and hard wheat hurt pigs' mouths (pp. 8–9). Fence off only what the herd cleans up in 15–20 days, or rain sprouts the peas and molds the corn; to size it, count how many days a fenced trial acre lasts (pp. 9, 11).

Winter feed: kale, roots, squash and artichokes

Thousand-headed kale (sown March–April, transplanted in June) stands in the field and feeds October–April, best from a rack; squash planted about May 25 and stored dark under straw feeds November–January (FB 599, p. 16), and squash and pumpkins are "favorite foods" (OSU EM 9271, p. 5). Mangels, beets, carrots and rutabagas go whole from the field (FB 599, pp. 17, 22), though good alfalfa does more (FB 1437, p. 10). Pigs dig Jerusalem artichokes on sandy creek land all winter (FB 599, p. 17). Cooked potatoes: 4Β½ lb equal 1 lb of corn, no more than 4 lb of potato to 1 of grain (FB 1437, p. 9). Chopped, soaked alfalfa hay can be half the ration of pigs you aren't hurrying (FB 599, p. 22), and unthreshed bundle grain carries dry sows through winter (p. 24).

Acorns and other mast

"Mast" is the nuts that fall in autumn. An English feeder reckoned a peck of acorns a day with a little bran put on about a pound a day for two months; California hogs ate raw acorns "with impunity," though in England they were "occasionally condemned as fatal" (Chesnut 1902, p. 353). OSU replaced 15–30% of a finishing ration with ground cull hazelnuts for the last 42 days, as Spain and Italy finish ham pigs on acorns (OSU EM 9271, p. 7). The oak poison is in young leaves, buds and green acorns (WSU, p. 27). Gather the ripe brown acorns of Oregon white oak, black oak and tanoak in September–November, feed them with other feed, never alone, and dry some for winter (rule of thumb). Bears work the same groves, so bring the acorns to the pigs, never the pigs to the woods (rule of thumb). Windfall fruit feeds pigs too, and picking it up keeps bears away (ODFW, p. 2).

Garbage, skim milk and whey: cook it first

Grain, protein and minerals

What not to feed

Never feed Why Source
Raw meat, bones or garbage that touched meat; any carcass; dead rats; raw bear or other wild meat Trichinosis, TB and more; wild trichinella survives freezing and smoking FB 1437, pp. 5, 38; Zoonoses, p. 120; "Disease and safety" in the Hunting guide
Raw poultry offal; raw milk or whey from untested animals Bird TB; cattle TB FB 1437, p. 11
Human waste: pigs must never reach a latrine Pork tapeworm, which can cause seizures in people Zoonoses, pp. 110, 112
Green or sprouted potatoes, potato and tomato vines, nightshade Solanine WSU, p. 21
Poison hemlock (pigs like it); water hemlock roots (pigs dig them) Death within hours; poison hemlock on days 30–60 of pregnancy deforms piglets AIB 415, p. 81; WSU, pp. 12–13
Cocklebur seedlings; early-spring death camas; hedge trimmings (yew, oleander, rhododendron); lots of green acorns Poisoning; yew kills before signs show AIB 415, pp. 113, 115; PNW 104, p. 2; WSU, pp. 15, 27
Salty slop, brine or cured-meat trimmings without plenty of water Salt poisoning: blind, deaf, convulsions, death No Animal Doctor, p. 332

Keep sheep out of the pig feed: it can hold enough copper to poison them (No Animal Doctor, p. 74).

πŸ’§ Water, shade and heat: pigs die of heat

"Pigs of all ages can overheat if they struggle, and can even die from heat stress. If boars overheat, they can be sterile for several months. Sows easily overheat when giving birth." Handle pigs only in the cool of early morning or evening (No Animal Doctor, p. 47). "Hogs suffer greatly from heat and must have shade" (FB 1437, p. 37), and sunburn is the other summer hazard (OSU EM 9271, p. 5).

  1. Water all day: ½–1Β½ gallons per 100 lb of pig, the high end for young pigs and nursing sows, more in heat (Peace Corps, p. 210): about 4Β½ gallons for a 300-lb nursing sow (arithmetic). Clean water whenever they want it, not twice a day in a foul trough (FB 1437, p. 12). Don't share a water source with pigs (Peace Corps, p. 210).
  2. Shade that breathes: trees in a clump, or a frame about 4 ft high roofed with hay, straw or weeds at least 2 ft deep, wetted on hot days so it drips, cooling the air and laying the dust. Low farrowing houses and A-frame huts are not shade: pigs crowd into them "even though they suffocate"; shut them in hot weather (FB 1437, p. 37).
  3. A wallow: FB 1437 wants 4–6 in of water in a shaded concrete wallow, changed often, and calls a mud wallow "a nuisance" because pigs drink the foul water (p. 37); the Peace Corps manual counts a mud wallow as heat protection (p. 286). In a valley August any wallow beats none: keep it shaded and refill it with clean water (rule of thumb).
  4. No work in the heat: no moving, weaning or hauling in the hot of the day; breeding above 86 Β°F (30 Β°C) "greatly" cuts fertility, so breed morning or evening (Peace Corps, p. 230).
  5. Smoke days: clean water, extra shade or sprinkling, and put off weaning, regrouping and hauling until the air clears (PNW783, p. 10).

Two side views: on the left an open shade about 4 feet high roofed with 2 feet of straw, wetted so it drips, with pigs lying under it; on the right a low A-frame hut crossed out, labeled as a heat trap to shut in hot weather Open straw shade, wetted on hot days; low huts trap heat and must be shut in summer (FB 1437, p. 37) (a diagram drawn for this guide).

A pig down in the heat (panting, open mouth, wobbling, lying flat): stop, get it into shade, pour cool water over it, especially the head, let it rest, then offer water; an overheated animal may not drink until it cools (No Animal Doctor, p. 124). A pig that went without water and acts blind or convulses has salt poisoning: small drinks often, not all it wants at once (p. 332).

🍼 Breeding, farrowing and piglets

What to know
Heat First at about 5 months if well fed (separate young boars and gilts by then); every 21 days, lasting 1–3 days: swollen red vulva, restless grunting; in standing heat she stands stock-still when you press on her back (Peace Corps, p. 228)
First breeding Not before 8 months, on her third heat, to farrow at about a year (same page; FB 1437, p. 22); don't rebreed a first-litter gilt for fall (same page)
Mating Twice, about 12 hours apart (Peace Corps, p. 230); a young boar serves one sow a day (FB 1437, p. 22). Write the date down
Gestation 114 days, "3 months, 3 weeks, and 3 days" (Peace Corps, p. 231); 112–115 in FB 1437 (p. 22). Bred December 15 = due about April 8 (arithmetic)
The boar Not used before 8 months; never one with a single testicle or from a ruptured litter (FB 1437, pp. 7–8). One serves 10–15 sows for 5–6 years (Peace Corps, p. 230); a borrowed boar can bring brucellosis (p. 282)
The pregnant sow In good flesh, not fat; about 1Β½ lb of feed per 100 lb of sow a day (2 lb for a gilt), with grain scattered in the field to make her walk (FB 1437, p. 13). A sow that eats her pigs was usually fed or kept badly (p. 15)

Getting ready to farrow

Farrow in spring when the nights have warmed: newborn pigs want about 95 Β°F for three days, then 85 Β°F over three weeks, and "demand the most heat of any young domestic livestock" (OSU EM 9271, p. 8); with no heat lamps you have timing, straw and the sow's own heat (rule of thumb). Not in August either: sows overheat giving birth (No Animal Doctor, p. 47).

  1. Pen her 3 days before she is due, in a dry, airy pen about 7 Γ— 7 ft with a guard rail of 2-by-4s (or pipe, which can't be chewed) around the inside, about 10 in off the floor and 4–6 in from the walls (FB 1437, p. 24), so a piglet lies safe in the gap when she lies down against the wall (Peace Corps, p. 288).
  2. Clean it with scalding water and lye, rinse and dry (FB 1437, p. 25), and if you can leave it empty in the sun for a few weeks (No Animal Doctor, p. 347). Bed it with dry wheat or rye straw or chopped hay, not oat straw, which stays wet; wash the mud off her sides and udder before she goes in (FB 1437, p. 25).
  3. Feed her outside in a yard 6–8 ft long off the pen: a sow fed among her piglets cripples or kills them (p. 26).
  4. A warm corner she can't enter: a boxed-in "hover" holds the piglets' own heat and stops drafts (OSU EM 9271, p. 8). A farrowing crate (4½–5 ft by 8 ft, the sow unable to turn) stays 20–25 Β°F warmer than the barn from her heat alone (FB 1437, p. 29; Peace Corps, p. 288).

A farrowing pen from above: about 7 by 7 feet with a guard rail all round, the sow lying in the middle, piglets along the walls, a warm corner only piglets can enter, and a door to an outside feeding pen 6–8 feet long; beside it a cut-through view of the wall showing a 2-by-4 rail about 10 inches up and 4–6 inches out, with a piglet lying safe under it The guard rail keeps the sow from pinning a piglet against the wall (FB 1437, pp. 24–26) (a diagram drawn for this guide).

Signs she is close: the udder fills 7–10 days ahead; colostrum (first milk) can be squeezed out within 24 hours; she grows restless, makes a nest, and may turn aggressive (Peace Corps, p. 231). Halve her feed the day before; none for 24 hours after, but plenty of lukewarm water (FB 1437, p. 15).

Farrowing night

Someone should be there, checking every hour with a light ready (FB 1437, p. 25; Peace Corps, p. 231).

  1. Each piglet: clear the membranes off the nose; if it isn't breathing, a few gentle slaps on the side or a brisk rub. Dry it, tie the cord with thread 1–2 in from the belly, cut beyond the knot, dip in iodine. Keep the litter in a box lined with sacks around warm bricks or a jug of hot water wrapped in cloth, and let them nurse if farrowing drags past 2–3 hours (FB 1437, p. 25; Peace Corps, p. 233).
  2. How long: 3–4 hours, about 15 minutes between pigs. Wait up to 4 hours, or a stillborn pig, before reaching in or giving oxytocin, both "last resort measures" for the experienced (Peace Corps, p. 233).
  3. The afterbirth ends it; a retained piece infects her, and a cloudy, smelly one may mean brucellosis (same page). Wear gloves (rule of thumb).
  4. Colostrum the first day or the piglet dies. A sow raises only as many as she has working teats: foster extras onto another sow, masking everyone's smell. A piglet under 1 lb has "no chance" (pp. 229, 233). A sow with no milk: undiluted cow's milk every 2 hours, Β½ in deep in a clean shallow pan (FB 1437, p. 14).

Piglets: crushing, cold, teeth and iron

Castration

Castrate boar pigs you won't breed: no stray litters or inbreeding, calmer pigs, and no boar taint (the foul smell of mature boar meat) (No Animal Doctor, p. 192; OSU EM 9271, p. 6). Do it at about 2 weeks, while they suckle, so they heal before weaning (FB 1437, p. 32; Peace Corps, p. 235).

  1. A helper holds the pig by the hind legs, or on its back in the lap, rump up. Feel for a hernia (gut in the scrotum): if there is one, don't castrate (No Animal Doctor, p. 192).
  2. Wash scrotum and hands. Press a testicle against the skin and cut low, ½–1 in long, so it drains; press it out and pull gently until the cord tears off near the body, which bleeds less than cutting; repeat on the other side (Peace Corps, pp. 235–236).
  3. Wash off the blood (it draws flies), dab on iodine, keep the pig on clean, dry bedding for 24 hours, and check it daily for 3 days (Peace Corps, p. 236). Grown boars bleed more and need a skilled hand (No Animal Doctor, p. 193).

Weaning and the next litter

Wean at 8 weeks or later: a good sow milks to 10–12 weeks, and a pig stunted by early weaning never catches up. Cut the sow's feed 4–5 days before, then take her away and leave the pigs in their pen (FB 1437, pp. 32–33). She comes back in heat 3–5 days later (Peace Corps, p. 229). Three litters in two years is a good average; fall pigs need extra care, and none should come after October 15 (FB 1437, pp. 33–34).

🩺 Pig health with no vet

Know normal: about 102.2 Β°F for a grown pig, 103.6 Β°F for a young one (No Animal Doctor, p. 66); OSU uses 102.5 Β°F Β± 1 (EM 9271, p. 4). Pulse and breathing are in Illinois Valley β€” Start Here. Watch daily for coughing, fever, going off feed, dullness and hard or fast breathing, and act at the first sign. Give shots in the neck just behind and below the ear, never the ham or loin, and wait out every withdrawal time before slaughter (EM 9271, p. 4). To hold a big pig, slip the loop of a finger-thick rope at least 10 ft long into its mouth behind the big canine teeth and tie it low to a post (No Animal Doctor, p. 47). Medicines in general: the Medical guide; this guide gives no doses.

Prevention does most of the work. The old USDA sanitation system controls most worms: a clean farrowing pen, the sow washed before farrowing, a clean trip to clean pasture, and clean pasture for the pigs until 4 months old (FB 1437, p. 41). Disinfect with soap and water, then chlorine or iodine, then 48 hours of sun (Peace Corps, p. 288). Change bedding before it is wet and foul (FB 1437, p. 37). Keep new pigs apart 30–60 days (rule of thumb; FB 1437 holds new breeding stock through two blood tests 60 days apart, p. 40).

Trouble Signs What to do
Large roundworm (Ascaris) Poor growth; white spots on the liver at butchering Clean pens, sun, fresh ground; worm sows the month before farrowing if you have a wormer (No Animal Doctor, pp. 346–347)
Swine flu Off feed, violent cough, vomiting, fever Warm dry quarters, rest, fresh water (FB 1437, p. 38)
Erysipelas High fever, hot swollen joints, purple ears and belly, raised diamond-shaped red patches; later lameness Penicillin if you have it (No Animal Doctor, p. 294). People catch it handling infected meat: gloves (FB 1437, p. 39)
Brucellosis Abortions, weak or stillborn pigs, sterility, hind-end weakness, swollen testicles Buy from clean herds, isolate newcomers, cull. It infects people: gloves at farrowings (FB 1437, pp. 39–40)
Tuberculosis Found at slaughter From TB birds and cattle and raw milk: cook offal, boil milk (FB 1437, p. 40)
Atrophic rhinitis Sneezing young pigs, later a twisted snout No cure once bent; clean, airy pens (No Animal Doctor, p. 293)
Lice and mange Scratching, scabby skin, poor growth Worst in thin pigs (Peace Corps, p. 274); clean bedding (No Animal Doctor, pp. 131–133); not the old dips
Scours in new feeder pigs Diarrhea 20% ground whole oats or 10% alfalfa in the feed for some weeks; warmth; sanitation (OSU EM 9271, pp. 3–4)

Dead pigs: never let pigs eat one; burn it, or bury it 4 ft deep under quicklime (FB 1437, pp. 38–39); see "Dead animals and gut piles" in the Sanitation guide.

πŸ”ͺ Butchering day

Planning a hog-killing day

A neighborhood scalding setup: a hog hanging from a gambrel on a 7-foot pole frame, a scraping platform 8 feet long with removable slats, and a scalding tank set in a brick firebox with a stovepipe Neighbors who kill several hogs a year can share a scalding vat over a firebox, a scraping platform and a hanging rail (AWI-68, p. 7).

Killing and sticking

Shoot or stun first, and make the first shot count (FB 2138, p. 7). The brain is small and behind thick sinuses: aim on the center line of the forehead, slightly above a line between the eyes, not between the eyes (UF VM114, p. 9), toward the spinal canal (AVMA, p. 119). A .22 long rifle does for young animals, but hollow points may not get through an adult skull: use a heavier bullet on old sows and boars. Hold the muzzle a few inches off the head (VM114, p. 5); bullets "glance from a hog's skull," so keep people and stock out of line (FB 2138, p. 7).

A pig's head from the front, with the aim point on the center line just above a dashed line between the eyes and a red X between the eyes; beside it a side view with an arrow entering the forehead and pointing back toward the spine Aim slightly above the eye line, on the center line, toward the tail (UF VM114, p. 9; AVMA, p. 119) (a diagram drawn for this guide).

Stick at once, with the hog hoisted by a hind leg or on its back, a helper astride holding the front feet (FB 2138, pp. 7–8): open the skin about 3 in in front of the breastbone; push the knife in edge down, straight toward the breastbone; follow the bone down until the knife slips under it and push about 1 in more; cut toward the backbone, then thrust forward toward the head to cut the artery. Stay on the center line or you stick a shoulder; don't stick the heart; let it bleed out. Keep the hole no wider than the blade, so scald water can't get in (Slaughter and Preservation of Meat, p. 62).

Cut-away drawing of a hog's neck and chest on its back: the knife shown in three positions, entering in front of the breastbone, sliding under it, and turned forward to cut the artery and vein, with the heart behind The knife (a) into the fat, (b) above the artery, (c) after the cut; the heart is not the target (USDA FB 2138, p. 8).

Scalding or skinning

Scalding keeps the skin for cracklings, salt pork and hams that store well, but takes much hot water and fuel. The books differ, and all work: 143 Β°F Β± 2 for 4–4Β½ minutes (Slaughter and Preservation of Meat, p. 63); 140–145 Β°F in a barrel, as hotter water may "set" the bristles (AWI-68, p. 7); or on a farm 155–165 Β°F to start, the hog kept moving and pulled out often (FB 2138, p. 9). Test, don't guess: when the hair on ham, flank, belly and head slips out, take the hog out (Slaughter and Preservation of Meat, p. 63). Scrape fast, before the skin sets: twist the hair off the legs, pull dewclaws and toes with the hook while hot, scrape with the bell scraper on edge, put sacks and hot water on stubborn patches, then rinse, singe and shave (FB 2138, pp. 9–11). Skinning suits hogs over about 250 lb: prop it on its back with bricks and skin it like a beef, slowly, since the skin is thin (Slaughter and Preservation of Meat, pp. 62–63); it needs no barrel or fire, but you lose the rind (rule of thumb).

Gutting, chilling and cutting

  1. Slip the gambrel under both big hind-leg tendons and hoist (FB 2138, p. 11). Split the breastbone; cut down between the hams, missing the bladder; open the belly with the knife handle inside and the point out (pp. 11–13).
  2. Tie off the bung (rear gut) (Slaughter and Preservation of Meat, p. 65), free the liver, cut the diaphragm, and lift out guts, heart and lungs without rupturing the guts. Save liver (gall bladder off), heart, tongue, and caul and ruffle fat for lard (FB 2138, pp. 13–15).
  3. Look before you eat: white spots on the liver mean roundworm (No Animal Doctor, p. 346); small shiny bladders, ½–1 cm, under the tongue or in jaw, heart, diaphragm or shoulder muscle are pork tapeworm cysts (Zoonoses, p. 111). Boil such offal and bury it under lime (Slaughter and Preservation of Meat, p. 67); bury a carcass full of cysts (rule of thumb).
  4. Wash out the cavity, saw down the backbone, pull the leaf fat while warm, and hang the halves apart, or hams and bellies spoil overnight (FB 2138, pp. 14, 16): dress in the afternoon, cut next morning (FB 1186, p. 16). If it turns warm, cut up the sides and hang the pieces to air, but nothing is as safe as cold (FB 2138, p. 19).
  5. Cut the cold carcass (pp. 18–23; cuts, p. 19): head off behind the ears; shoulder off between the 2nd and 3rd ribs, split into picnic (cure it with the hams), butt and fat plate (lard or salt pork); ham behind the rise of the pelvic bone; loin sawn off the bacon; spareribs lifted off the bacon; jowls cured like bacon.

Eat, cure or can fresh pork within 3–5 days: it spoils faster than other meat (FB 2138, p. 24), and can it only in a pressure canner (pp. 39–40). Curing, smoking and storing hams and bacon: "Curing pork and venison" in the Preserving Food guide; smoke with hardwood, never pine, at 100–120 Β°F, in a smokehouse at least 50 ft from other buildings (FB 2138, pp. 32–34).

πŸ“š Go deeper: USDA FB 2138 β€” the whole job in photos; AWI-68 β€” hoists, scald vats, smokehouses; Oregon custom-exempt FAQ, p. 2 β€” in normal times custom-killed meat "cannot be sold, traded, bartered or given away," so trade live pigs or shares of a live pig.

πŸ«™ Rendering lard and cracklings

Lard is 9–13% of the live weight of a meat-type hog and 14–18% of a fat one (FB 2138, p. 6); a 225-lb hog gave 27 lb of fat for the kettle (p. 22).

  1. Sort it. Leaf fat (from around the kidneys) makes the best lard; render it apart for baking. Back fat and trimmings make the rest; caul and ruffle fat from the guts give darker lard, so render them separately (FB 2138, p. 40); strong intestinal fat is for soap (Minnesota, p. 2).
  2. Keep it cold and render soon: at 32–35 Β°F no more than 5–7 days (same page).
  3. Cut it small; take off the skin for whiter lard and pick out every bit of lean, which browns and darkens it (same page; FB 2138, p. 23).
  4. Kettle: iron, steel or aluminum, never copper. A little water in the bottom, a small batch on a low fire, the rest added as it melts; don't fill it, or it boils over (Minnesota, p. 3; FB 2138, p. 40).
  5. Heat: it sits near 212 Β°F while the water cooks off, then climbs; hold 235–245 Β°F (Minnesota, p. 3), never above 255 Β°F (FB 2138, p. 42). Stir often so nothing scorches.
  6. Done when the bubbling stops and the cracklings float, chestnut-brown and easily crushed; fully rendered they sink. Full rendering drives out the water so the lard keeps (same pages).
  7. Strain through two or three layers of cheesecloth, press the cracklings, and pour into clean, scalded, dry crocks or tins of 5–10 lb, filled to the top; cool fast and store dark and cool, below 50 Β°F (FB 2138, p. 42; Minnesota, pp. 3–4).

Yields: leaf fat 90–93% lard; mixed leaf, back and cutting fat 80–85%; gut fat 55–65%; pressed cracklings 4–6% of the fat (FB 2138, p. 42): the 27 lb of fat makes roughly 22 lb of lard (arithmetic). Air, light, water left in, and warm storage make lard rancid; 10% beef fat firms soft lard; slightly rancid lard is rescued by heating it with sliced potatoes until they brown, then straining (Minnesota, p. 4). ⚠️ Hot fat burns badly: keep children back, keep a lid at hand to smother a fire, and never put water on burning fat (rule of thumb). Eat the cracklings as they are or in cornbread (rule of thumb). More in "Salt, sweeteners and fat" in Food From Scratch; soap in "Soap from fat and ashes" in the Make-Do Household guide.

🦠 Keeping pigs and people safe

Trichinosis is a worm in the muscle of pigs, rats, bears and other meat-eaters, caught from raw or undercooked meat, most often pork. 8–15 days later come sudden muscle pain and swollen upper eyelids, then eye pain, sweats and fever to 104 Β°F; heart and nerve damage can kill in weeks 3–8 (Zoonoses, pp. 120–121). If that follows a meal of pork or bear, see the Medical guide.

Pork tapeworm (Taenia solium): pigs get the cysts by eating human feces; people get the tapeworm from undercooked pork, and its eggs can grow cysts in another person's brain, "the major cause of seizures" in many poor countries (Zoonoses, pp. 109–110). Pigs must never reach a latrine, outhouse pit or human waste, raw sewage must not fertilize their ground, and all pork must be cooked well (pp. 112–113); salting and pickling don't kill the cysts (p. 113). Latrines are in the Sanitation guide.

Also from pigs: erysipelas from handling infected meat, brucellosis, and TB through raw milk and garbage (FB 1437, pp. 39–40). Wear gloves to butcher and to help a farrowing, cover cuts, wash well, and keep pregnant women away from abortions and afterbirths (rule of thumb). Bites, kicks and knife cuts: Field Care guide.

🚫 Never let pigs go feral

A pig that gets loose for good does not stay a farm pig (rule of thumb). Free-ranging pigs spread diseases and parasites to people, lose more to predators, and breed with no control (Peace Corps, p. 285); free-range village pigs are "not-too-distant offspring" of wild ones (p. 283). A gilt can come in heat at about 5 months and farrow 114 days later (pp. 228, 231), and a good sow raises 8 or more (FB 1437, p. 7): one loose pair can be dozens within two years (arithmetic). Feral pigs root up meadows, camas beds and creek banks, raid gardens and grain, carry brucellosis and trichinella, and a wild sow is dangerous (rule of thumb).

πŸ“… A pig year in the Illinois Valley

When Pigs Work
Dec–Jan Sows bred; fat hogs ready; mud Kill, cut, render and cure on cold dry days; breed sows (bred Dec 15 = farrow about Apr 8 (arithmetic)); pigs on the drained winter lot or ryegrass sod; kale, roots, squash, artichokes and bundle grain
Feb–Mar Pregnant sows Winter wheat and vetch pasture; sow peas, beardless barley and spring grain to hog off; dig and seed old pig lots; clean farrowing pens and leave them in the sun
Apr–May Farrowing Pens ready 3 days early; snip teeth; sods for iron; castrate at 2 weeks; creep at 3 weeks; plant rape (Apr 1, 15, 30), corn (Apr 20–May 10), squash (May 25)
Jun–Jul Weaned at 8–10 weeks; heat begins Wean onto clean pasture; shade, wallow and water daily; transplant kale; hog off barley (Jul 1–20) and wheat (Jul 10–Aug 10); no open burning in fire season (Wildfire guide)
Aug–Sep Growing pigs; heat and smoke Peas hogged off to Oct 1; no hauling or breeding in the heat of the day; rebreed a grown sow early in the morning for a fall litter
Oct–Nov Acorns fall; rains start Corn hogged down; acorns, hazelnuts and windfalls; sow vetch, ryegrass and winter wheat; pigs off soggy pasture; no fall litter after Oct 15 (FB 1437, p. 33); plan the kill

Crop dates are the book's for western Oregon (FB 599, pp. 12–16); the fit to our valley is a rule of thumb. April pigs are 7–8 months old by December, when FB 599's well-fed pasture hogs reach 170–225 lb (p. 5); OSU says feeder pigs can be ready at six months (EM 9271, p. 5).

πŸ‘ͺ How many pigs feed a family

Goal What it takes Source
Pork and lard One 200-lb meat-type hog β‰ˆ a year's pork and lard for two. A family of four: 2 hogs; 3–4 if pork and lard are your main meat and only fat FB 2138, p. 6 (arithmetic; rule of thumb)
One hog gives 225 lb live β†’ 176 lb carcass β†’ 113 lb hams, picnics, bacon, loin and butt, 34 lb ribs, sausage, feet and head, 27 lb fat (β‰ˆ 22 lb lard) FB 2138, p. 22 (lard: arithmetic)
Grain 300–350 lb of grain plus 25–35 lb of protein feed per 100 lb of gain on full feed: about 600–700 lb of grain to raise a weaned pig. Less with pasture, milk and scraps, but slower FB 1437, p. 17 (arithmetic)
Grain land At 30 bushels (1,800 lb) of wheat an acre, about ⅓–⅖ acre of grain per hog FB 599, p. 11 (arithmetic)
Pasture 8–16 hogs an acre on clover or alfalfa: about ΒΌ acre for two feeders, in two paddocks FB 599, p. 12 (arithmetic)
Water Two 200-lb hogs and a nursing sow: about 10 gallons a day in summer Peace Corps, p. 210 (arithmetic)
Breeding stock 1–2 sows and a share in a boar. One sow raising 8 pigs, three litters in two years, gives about 12 pigs a year: enough for 3–4 families, or for trade FB 1437, pp. 7, 33 (arithmetic)
Or buy feeders 2 weaned pigs in spring, killed in winter: no sow or boar to feed all year, but only while someone nearby keeps sows (rule of thumb)

🧬 Keeping the line going

Ear notches last for life where tags tear out. Notch soon after farrowing, while wounds heal fast, with small sharp side-cutting pliers, deep enough to take some cartilage (FB 1437, pp. 35–36). Each notch place has the value printed beside it in the drawing; add up a pig's notches to read its number, and write it down with its mother's (how to read the drawing).

A pig's face from the front with notch places on both ears: on the pig's right ear 3000, 9000 and 1000 along the top edge, 30 at the tip, 90 and 10 along the lower edge; on the left ear 300, 900 and 100 along the top, 3 at the tip, 9 and 1 along the lower edge The ear-notch numbering system; "right" and "left" are the pig's own ears (USDA FB 1437, p. 36).

🧯 If this goes wrong

Problem Likely cause and fix
Piglets found flat and dead the first days Crushed: guard rail, warm corner, someone at the farrowing (FB 1437, pp. 24, 26, 29)
Piglets shivering in a heap Cold and drafts: dry straw, a closed-in warm corner, a box with warm bricks (OSU EM 9271, p. 8; FB 1437, p. 25)
Piglets pale, rough-coated, gasping at 2–3 weeks Iron: fresh sod or clean soil (FB 1437, p. 32)
Sow eating her pigs Poor feed and care in pregnancy; cull if it happens again (FB 1437, p. 15)
Sow has no milk Cow's milk every 2 hours in a shallow pan, or foster (FB 1437, p. 14; Peace Corps, p. 229)
Pig down, panting, on a hot day Shade, cool water on the head, rest, then water (No Animal Doctor, p. 124)
Pigs digging out; fence weak in August Hot wire near the bottom; in dry soil make the low wire a ground wire (OSU EM 9271, p. 5)
Sow won't settle Breed twice, 12 hours apart, in standing heat, in the cool of the day (Peace Corps, pp. 228, 230)
Hair won't scrape off Water too hot (hair "set") or too cool; sacks and hot water on stubborn patches (FB 2138, p. 9)
Meat bloody and spoiling Hog chased or hot when killed, or bled poorly (FB 2138, p. 6)
Ham smells sour at the bone Run a sharpened wire along the bone; if it smells rotten, destroy the piece (FB 2138, p. 35)
Lard went rancid Water left in, light, air or storage over 50 Β°F (Minnesota, p. 4)
Sore muscles and puffy eyelids a week after eating pork Trichinosis: get medical help (Zoonoses, p. 121)

⚠️ Old advice in the library to ignore
