Record Keeping

Part of Veterinary Medicine

Designing and maintaining livestock health and production records to support diagnosis, management decisions, and breeding selection.

Why This Matters

Livestock records are institutional memory. Without them, every problem you encounter is new, every decision is made from incomplete information, and every year’s experience is lost when the person who had it is unavailable. With good records, a problem seen today can be compared to the same problem last year, in the same animal, under similar conditions — and that comparison often reveals the answer.

In a subsistence or community livestock operation, records serve multiple functions simultaneously. They support individual animal health management (what has this animal had, what worked, what didn’t). They support herd-level management (which diseases appear in which seasons, are we seeing the same problems repeatedly). They support breeding decisions (which animals produce healthy offspring, which have chronic health problems that suggest poor genetics). And they support community knowledge transfer — records written today teach the next generation of animal keepers without them having to relearn everything from scratch.

The barrier to record-keeping is usually perceived complexity. Effective livestock records do not require forms, databases, or computers. A notebook with consistent entries provides 80% of the value of elaborate systems. The commitment to writing something down every time something happens is the essential discipline.

What to Record

Focus on high-value data that you will actually use for decisions:

Individual animal identification:

• Species, breed, sex
• Date of birth (or estimated age at acquisition)
• Physical description or ear tag/notch/brand identifier that allows unambiguous identification
• Dam and sire if known
• Source (born on farm, purchased — from where)

Reproductive history:

• Date and male used for each breeding
• Date of confirmed pregnancy (if detectable)
• Birth date and number of offspring (single, twins, triplets)
• Birth weight if measurable
• Outcome: normal birth, assisted, cesarean, neonatal death, dam problems
• Weaning date and weight

Production history:

• Milk production (at least weekly in dairy animals during lactation)
• Estimated meat yield at slaughter
• Fleece weight and quality at shearing (for sheep)

Health history:

• Date and description of any illness or injury
• Clinical signs observed
• Diagnosis (if established)
• Treatment given: what, how much, by what route, for how many days
• Outcome: recovered, chronic, died, culled
• Vaccinations: date, vaccine name, lot number if available
• Deworming: date, product used, dose, FAMACHA or fecal egg count result

Body condition scores: Recorded at each assessment (minimum quarterly)

Mortality: Date, approximate age, apparent cause, disposal method

Recording Systems

Paper notebook: The simplest and most durable recording system. A hardcover notebook with one section per animal, updated with each event. Resilient to power outages, software obsolescence, and equipment failure. Disadvantage: difficult to search and aggregate across animals.

Card system: One index card per animal kept in a card box sorted by ID or birth year. Each card contains the animal’s full history. Easy to pull the card for a specific animal during examination. Cards can be filed chronologically, by sex, by production group, or by health problem type. Disadvantage: cards deteriorate and can be lost.

Register format: A large ledger with each row representing one event and columns for date, animal ID, event type, and details. Allows quick scanning of all events over a time period — useful for identifying patterns. Best used alongside individual animal cards rather than as a replacement.

Digital records: Where computers or tablets are available and reliable power is accessible, spreadsheets or dedicated livestock management software provide powerful search and analysis capability. The risk in a post-collapse context is data loss if hardware fails and no backup system exists. If digital records are used, maintain a paper backup of essential data.

Designing a Simple Health Record Card

The following layout fits on a standard index card or half sheet of paper:

ANIMAL ID: ______  SPECIES/SEX: ______  DOB: ______
DAM: ______  SIRE: ______  SOURCE: ______
DESCRIPTION: ______________________

VACCINATIONS:
Date | Vaccine | Dose | Notes
_____|_________|______|______

TREATMENTS:
Date | Problem | Treatment | Outcome
_____|_________|___________|________

REPRODUCTION:
Date | Event | Male | Notes
_____|_______|______|______

BODY CONDITION SCORE:
Date | BCS | Notes
_____|-----|------

NOTES: ___________________________

Keep the card in a waterproof sleeve or copy important data to a master register periodically.

Herd-Level Summary Records

Beyond individual records, maintain aggregate records that support herd management:

Monthly mortality report: Total animals by species at start of month, deaths (with cause), births, and total at end. Track mortality rate trends over time. Rising mortality rates in specific age classes trigger investigation.

Reproductive summary (annual): Breeding dates, conception rates, birth outcomes, neonatal mortality rates, weaning weights. Compare year-over-year to identify improvements or deteriorations.

Parasite monitoring log: FAMACHA scores and treatment decisions by round. Track the proportion of animals treated per round — a rising proportion indicates worsening pasture contamination or drug resistance.

Vaccination coverage: Which animals are due, which are current, which are overdue. A simple checklist updated at each vaccination round ensures no animals are missed.

Feed and supplement inventory: Recording what was fed and when supports troubleshooting of nutritional problems. If a cohort of animals developed white muscle disease, knowing that selenium supplementation was provided can help rule it in or out as a cause.

Using Records for Decision-Making

Records are only valuable if they are consulted. Build habits of record use:

Before treating any sick animal: Review its health history. Has this happened before? What was tried, and did it work? Are there patterns (same time of year, same production stage)?

Before making breeding decisions: Review health records of candidates. Animals with chronic conditions, difficult births, poor offspring survival, or metabolic disorders should be weighted against animals with clean health histories.

When disease clusters appear: Pull records for all affected animals. Do they share a common characteristic (age class, pen, source, vaccination status)? The common factor often points toward the cause.

At herd-level reviews (annual minimum): What problems occurred most frequently? What caused the most deaths? What was the cost in animals and treatments? This review drives the planning of prevention priorities for the coming year.

When training new animal keepers: Records are the curriculum. A new herdsperson who can read the health history of every animal in the herd starts with years of accumulated knowledge rather than blank ignorance. In a community context, this knowledge transfer is a form of institutional resilience — the knowledge lives in the records, not only in individual people.

Retention and Backup

Keep individual animal records for the animal’s lifetime plus 2 years (for disease investigations). Keep herd-level summary records permanently — these represent decades of experience that future generations can learn from.

In a disruption scenario where records might be lost: periodically transcribe the most important data (herd composition, breeding records, disease history) to a secondary copy kept in a different physical location. A waterproof, fireproof container or a copy held by another household in the community protects against the most common causes of record loss.
