Health and Veterinary Care

Part of Animal Husbandry

When there are no veterinarians, you are the veterinarian. Livestock health management in a post-collapse world depends on prevention, early detection, and a working knowledge of treatments you can prepare yourself.

The Prevention-First Principle

Treating a sick animal is difficult, uncertain, and often too late. Preventing illness is straightforward and effective. Eighty percent of livestock health problems trace back to four causes: bad nutrition, dirty water, overcrowding, and parasite overload. Fix those and you eliminate most emergencies before they start.

The Four Pillars of Livestock Health

Pillar	What It Means	How to Maintain
Nutrition	Adequate calories, protein, minerals	Managed pasture, quality hay, mineral supplementation
Clean water	Fresh, uncontaminated water daily	Protect water sources from feces; clean troughs weekly
Space and ventilation	Adequate room, dry bedding, airflow	Rotational grazing; shelters with cross-ventilation
Parasite management	Low internal and external parasite burden	Pasture rotation, herbal treatments, dung management

Daily Health Checks

Every time you see your animals, you should be assessing them. This takes seconds once you know what to look for — it becomes automatic.

The 30-Second Visual Check

Observe each animal for:

1. Posture — Standing normally? Head up? Weight on all four legs?
2. Movement — Walking freely or limping? Lagging behind the group?
3. Eating — Grazing or chewing cud actively? Or standing apart with no interest in food?
4. Eyes and nose — Clear and bright? Or dull, with discharge?
5. Coat — Smooth and glossy? Or rough, dull, or patchy?
6. Droppings — Normal consistency and color? Or diarrhea, blood, mucus?
7. Behavior — Acting normally? Or isolated, depressed, restless, or aggressive?

Any deviation from normal warrants closer inspection. Animals are prey species — they hide illness until it is advanced. By the time a cow looks obviously sick, the problem has likely been developing for days.

Common Conditions and Treatments

Bloat (Ruminants: Cattle, Goats, Sheep)

Cause: Gas trapped in the rumen, often from sudden access to lush legume pasture (clover, alfalfa) or grain.

Signs: Distended left flank (visibly swollen, drum-tight), distress, difficulty breathing, refusal to eat, standing with legs spread.

Treatment:

1. Mild bloat: Walk the animal continuously — movement helps gas pass. Massage the left flank firmly in upward strokes.
2. Moderate bloat: Drench (pour down throat) with 1 cup of vegetable oil or lard mixed with warm water. The oil breaks the foam trapping gas.
3. Severe bloat (animal cannot breathe): This is an emergency. Insert a stomach tube (any smooth flexible tube, 1/2 inch diameter, 5-6 feet long) through the mouth into the rumen. Gas will rush out. If no tube is available, puncture the rumen through the left flank with a sharp knife or trocar — aim at the highest point of the distension, halfway between the last rib and the hip bone.

Rumen Puncture

Puncturing the rumen is a last resort to save a dying animal. It creates an infection risk and requires aftercare (keep the wound clean, flush daily with salt water). Only do this when the animal will die without intervention.

Prevention: Introduce animals to legume-heavy pasture gradually. Never turn hungry animals onto lush clover.

Foot Rot

Cause: Bacterial infection of the hoof, thrives in wet, muddy conditions.

Signs: Lameness (often sudden), swollen area above the hoof, foul smell, reluctance to walk, grazing on knees.

Treatment:

1. Restrain the animal and clean the affected foot thoroughly.
2. Trim away any dead, decayed tissue with a sharp knife. You need to expose the infection to air.
3. Soak the foot in a strong salt solution (1 cup salt per gallon of warm water) for 15-20 minutes.
4. Apply a poultice of crushed garlic mixed with honey — garlic is antimicrobial, honey seals the wound.
5. Keep the animal on dry ground during recovery (5-10 days).

Prevention: Maintain dry, well-drained animal housing areas. Trim hooves every 6-8 weeks. A foot bath at paddock entrances (shallow trough of salt water that animals walk through) reduces infection rates significantly.

Internal Parasites (Worms)

Cause: Livestock ingest parasite larvae while grazing. Larvae mature in the gut, lay eggs passed in feces, and reinfect pasture.

Signs: Weight loss despite adequate feed, dull coat, anemia (pale gums and inner eyelids), diarrhea, bottle jaw (fluid swelling under the chin in severe cases).

Treatment — Herbal Dewormers:

Plant	Preparation	Dosage (per 100 lbs body weight)	Notes
Wormwood (Artemisia)	Dried leaf tea	1 tablespoon dried herb steeped in 1 cup hot water	Do not use on pregnant animals
Garlic	Fresh crushed cloves	2-3 cloves mixed into feed	Safe, mild; use regularly as preventive
Pumpkin seeds	Raw, ground	1/4 cup ground seeds	Effective against tapeworms especially
Tobacco leaf	Dried, crumbled	1 teaspoon mixed in feed	Toxic in excess — use sparingly
Diatomaceous earth	Mixed in feed	1 tablespoon per 100 lbs	Mechanical action; debated effectiveness

Herbal Dewormers Are Weaker Than Pharmaceuticals

These treatments reduce parasite load but rarely eliminate it completely. Combine with pasture rotation (the most effective parasite control) and good nutrition so animals can tolerate moderate worm burdens.

Prevention through grazing management:

• Rotate pastures — parasite larvae die after 3-6 weeks without a host. Long rest periods break the cycle.
• Mixed-species grazing helps: cattle parasites cannot infect goats and vice versa, so alternating species on a paddock reduces parasite pressure for both.
• Do not graze pasture shorter than 3 inches — most larvae concentrate on the bottom 2 inches of grass.

Mastitis (Dairy Animals)

Cause: Bacterial infection of the udder, usually from dirty milking conditions or incomplete milking.

Signs: Hot, swollen, painful quarter; discolored or clumpy milk; animal kicks or flinches during milking; reduced milk production.

Treatment:

1. Milk the affected quarter completely, every 4-6 hours. Discard this milk.
2. Apply warm compresses to the udder for 15 minutes before each milking.
3. Massage the quarter gently downward during milking to help express infected material.
4. Apply a poultice of comfrey leaves and honey after milking.
5. Administer garlic internally (several crushed cloves in feed daily) for antimicrobial support.
6. If the quarter becomes cold, blue/black, or the animal develops a fever and stops eating, the infection has gone systemic. Isolate the animal and increase supportive care (warmth, fluids, rest).

Prevention: Wash hands and udders before milking. Milk into clean containers. Milk completely — residual milk is a bacterial growth medium. Dip teats after milking in a dilute vinegar solution.

Wound Care

Livestock get injured — torn on fences, kicked by herd mates, gored, cut on debris. Basic wound management saves lives.

Wound Treatment Protocol

1. Control bleeding — apply direct pressure with clean cloth. Most livestock wounds bleed impressively but stop within minutes.
2. Clean the wound — flush thoroughly with clean water or salt water (1 teaspoon salt per quart). Remove all debris, dirt, and dead tissue.
3. Assess depth — shallow cuts heal on their own. Deep cuts exposing muscle or tendon need closure.
4. Close deep wounds — suture with clean thread and a curved needle if you have the skill. Otherwise, pull wound edges together with adhesive strips or butterfly bandages from cloth.
5. Apply antimicrobial — raw honey is excellent (naturally antibacterial, promotes healing, seals the wound). Crushed garlic mixed with clean fat works as well.
6. Cover if possible — bandage to keep flies out. Fly-blown wounds (maggot infestation) are a serious secondary problem in warm climates.
7. Monitor daily — redness spreading outward, heat, swelling, foul smell, or pus indicate infection. Re-clean and re-treat.

Fly Strike Prevention

In warm months, any wound or soiled wool/hair attracts blowflies that lay eggs in the tissue. Maggots hatch within hours and begin consuming flesh.

• Keep wounds clean and covered.
• Shear wool around the rear end of sheep to prevent fecal soiling (a primary fly strike target).
• Apply pine tar, neem oil, or a thick paste of wood ash and fat over wounds — these repel flies.

Quarantine Procedures

When an animal shows signs of potentially contagious disease (especially respiratory symptoms, unusual lesions, or sudden death), isolate immediately.

1. Move the sick animal to a separate enclosure at least 50 feet from the main herd.
2. Handle the sick animal last — after all healthy animal chores are complete.
3. Wash hands and change clothes/footwear between sick and healthy groups.
4. Do not share feed buckets, water troughs, or equipment.
5. Observe the rest of the herd closely for 2 weeks for similar symptoms.

Key Takeaways

• Prevention beats treatment every time — good nutrition, clean water, rotational grazing, and dry housing prevent 80% of livestock health problems
• Learn the 30-second visual check and perform it every day — early detection is your greatest advantage
• Bloat kills fast — know the signs and have oil and a stomach tube ready
• Pasture rotation is the best dewormer — long rest periods break parasite life cycles more effectively than any herb
• Honey is your best wound treatment — antimicrobial, protective, and available anywhere bees exist
• Quarantine aggressively — one sick animal spreading disease to your whole herd is a catastrophic loss
• Keep calm and act systematically — panicking helps no animal; methodical assessment and treatment does
