Everything in livestock is a system with feedback, and single-variable optimization reliably
backfires: maximize milk and lose fertility, maximize growth and increase maintenance cost,
maximize stocking rate and lose the pasture that fed the animals. The two engines of livestock
agriculture are the soil and the rumen (§8 → `homestead-livestock-digestion-nutrition-and-species`).

## §11 Housing and fencing

Shelter requirements vary by species and climate. Fencing is **the most important infrastructure
investment** on the place.

| Species | Shelter | Fencing |
|---|---|---|
| Cattle | In temperate climates, windbreak and shade — but not enclosed housing | Respect a single smooth wire at **30–32 inches** if trained to it, but most farms use **4–5 wire high-tensile electric** |
| Sheep | Shelter from wind and wet during lambing | Mesh, or offset electric wires — they go **under**, not over |
| Goats | Dry shelter — they hate rain | Require the best fencing: **4–5 foot woven wire with offset hot wires**, or **7–8 strand high-tensile** |
| Pigs | Sun protection and wallows — they cannot sweat | Need the strongest fencing: woven wire with a **hot wire at nose level**, or hog panels |
| Poultry | Predator-proof housing with roosts, nest boxes, and ventilation | Predator-proof runs with top covering, or electric fencing offset |

Goats are escape artists and fencing must be excellent; pigs are strong, smart, and need sturdy
fencing; poultry housing must be secure against predators (§10 →
`homestead-livestock-digestion-nutrition-and-species`).

**Water systems.** Clean, accessible water in **every paddock**. Automatic waterers with float
valves are the standard. In freezing climates, use heated waterers or waterer cups. Animals drink
**10–30 gallons per day** depending on species and size — plan supply accordingly. Water is the most
important and most neglected nutrient: animals will not eat if they cannot drink.

## §12 Herd health and biosecurity

> **PREVENTION IS THE WHOLE GAME; TREATMENT IS FAILURE MANAGEMENT**
>
> Biosecurity is the single highest-value practice. Quarantine incoming animals for **21–30 days**.
> Control visitor and vehicle traffic. Clean and disinfect equipment between groups. Manage the
> wildlife–livestock interface. A disease outbreak can kill or condemn more animals than any
> predator.

**Vaccination.** Core programs by species and region. Timing matters — build immunity *before*
challenge. For newborns, colostrum management is critical: newborns need adequate colostrum
**within the first few hours of life** for passive transfer of immunity. Failure of passive transfer
predicts sickness and death.

**Parasites.** Internal parasites — especially the barber pole worm, *Haemonchus contortus*, in
small ruminants — are the major killer. Anthelmintic resistance is now **severe and widespread**,
and the old "deworm everyone on a schedule" approach caused it. Current best practice is
**selective (targeted) deworming** using:

- **FAMACHA scoring** — eyelid mucous-membrane colour assessment for anemia in small ruminants,
  used for targeted selective deworming against barber pole worm: score the membrane, treat only the
  animals the score calls anemic, and leave the rest untreated so a susceptible population survives
  in refugia.
  > ⚠️ **The source's own wording of the thresholds is internally inconsistent** — it reads
  > "Red/pink = anemic = treat; bright pink/red = healthy = don't treat", which assigns the same
  > colours to both outcomes. Do **not** act on that sentence. Read the thresholds off an official
  > FAMACHA card, from the trainer who certified you, or from your vet before deworming: getting the
  > direction backwards means treating healthy animals and leaving anemic ones to die.
- **Fecal egg counts.**
- **Refugia**: deliberately leave a population of unselected parasites so resistance does not fix in
  the population. *This is counterintuitive and it is correct.*

**Nutrition-linked diseases.** All of these are preventable through nutrition management:

| Disease | Cause |
|---|---|
| Acidosis | Too much starch |
| Bloat | Foam or gas |
| Milk fever | Calcium deficiency at calving |
| Ketosis | Energy deficiency in late pregnancy or early lactation |
| Grass tetany | Magnesium deficiency on lush spring grass |

Acidosis and bloat are rumen-fermentation failures — the mechanism, and the one-to-three-week
microbial adaptation window that makes abrupt diet change dangerous, are in §8 →
`homestead-livestock-digestion-nutrition-and-species`.

**Zoonoses to respect.** Rabies, leptospirosis, brucellosis, Q fever, salmonella, cryptosporidium,
ringworm, orf. Practice good hygiene, wear gloves when handling sick animals or birth fluids, and
consult a veterinarian for any unusual illness.

## §13 Reproduction and breeding

Reproductive efficiency is usually the **largest economic lever** in a livestock operation. A cow
that does not wean a calf costs a full year of maintenance for nothing.

**Nutrition drives reproduction.** Thin females do not cycle, and the interval from calving to
first estrus lengthens sharply with poor body condition. Body condition scoring is the practical,
free tool; condition at calving or lambing predicts rebreeding success better than almost anything
else you can measure (§9 → `homestead-livestock-digestion-nutrition-and-species`).

**Tools.**

- **Artificial insemination (AI)** — access to superior genetics without buying a bull.
- **Estrus synchronization protocols** — synchronize cycling females for batch breeding and
  batch lambing/calving.
- **Pregnancy diagnosis** — by palpation, ultrasound, or blood test.
- **Embryo transfer and sexed semen** — for advanced programs.

**Dystocia.** Calving difficulty risk is driven substantially by **sire selection** (birth weight
EPDs — expected progeny differences) and by **heifer size at breeding**. Both are manageable in
advance. Choose low-birth-weight sires for first-calf heifers.

**Genetics.**

- EPDs predict a sire's progeny performance relative to **a breed's base** — they are **not
  comparable across breeds**. Accuracy values matter as much as the figure itself.
- **Selection indexes beat single-trait selection**, because single-trait selection reliably
  produces correlated problems. The classic expensive example: selecting hard for growth increases
  mature cow size and therefore maintenance cost.
- **Crossbreeding and heterosis** produce the largest gains in low-heritability fitness traits —
  fertility, survivability, longevity.

Gestation lengths and estrous cycles by species, including the seasonal breeders, are tabulated in
§10 → `homestead-livestock-digestion-nutrition-and-species`.

## §14 Grazing management and welfare

Grasses grow from **basal meristems** and regrow from energy reserves and residual leaf area.

> **Rest period is what allows recovery; overgrazing is a function of time, not of animal numbers.**
> An animal returning to the same plant before it recovers is the damage mechanism. This insight
> changes everything about how you manage grazing.

**"Take half, leave half"** — removing more than about **half the leaf volume** sharply reduces root
growth, weakening the plant and slowing recovery. This is a rough heuristic but a good starting
point.

### Grazing systems

| System | Description | Trade-Off |
|---|---|---|
| Continuous grazing | Animals stay in one paddock. Simple. | Selective grazing degrades preferred species. Overgrazing of palatable plants, underuse of others. |
| Rotational grazing | Multiple paddocks with rest periods between grazing. | More fencing and water infrastructure. Better pasture utilization and recovery. |
| Mob/high-density grazing | Short duration, high density, long rest. | Most management-intensive. Claims for soil carbon and productivity gains are contested in controlled trials, but adequate rest periods do improve pasture composition and productivity. |

### Stocking rate, density, and the forage curve

- **Stocking rate** = animals per acre **over time**. **Stocking density** = animals per acre **at a
  moment**. They are different numbers and answer different questions.
- An **Animal Unit (AU)** is the standardizing measure: one **1000-pound cow with calf is 1 AU**;
  **approximately five sheep _or_ five goats are 1 AU**. That equivalence is what lets you compute a
  stocking rate across a mixed flock and herd on one figure.
- Match forage supply curves to herd demand across the year. In most temperate regions, forage
  growth is concentrated in **spring and early summer** — plan for the surplus (make hay) and the
  deficit (feed hay) periods.

> **MANAGEMENT SKILL MATTERS MORE THAN THE SPECIFIC SYSTEM**
>
> On the intensive-grazing debate: controlled trials have often failed to reproduce the largest
> claimed effects of adaptive multi-paddock grazing on soil carbon and productivity. What is
> well-supported is that adequate rest periods improve pasture composition and productivity, and
> that management skill and adaptive decision-making appear to matter more than the specific system
> chosen. Observe your pasture, adjust your rest periods, and move animals based on **plant
> recovery, not the calendar**.

The same candour applies to the wider claims about regenerative systems and soil carbon — see
§21 → `homestead-crops-rotation-pests-and-water`.

### Welfare

*This closes Part II of the reference; it is grouped here because it governs every practice above.*

**The Five Freedoms** are the historical framework: freedom from hunger and thirst, from
discomfort, from pain/injury/disease, from fear and distress, and the freedom to express normal
behavior.

**Welfare is measurable, not merely ethical**: lameness scoring, body condition, injury rates,
cortisol levels, behavioral indicators, and productivity itself. Stressed animals perform worse, so
welfare and production interests align more often than the debate implies.

**Low-stress handling** (Temple Grandin's work):

- **Flight zone** — the animal's personal space. Enter it and the animal moves away.
- **Point of balance** — the animal's shoulder. Move ahead of it and the animal moves back; move
  behind it and the animal moves forward.
- Animals move **away from perceived threat and toward light**.

Handling that relies on force is usually handling that misunderstands the animal. Work with their
instincts, not against them.
