What should a breeding record include?
For each female, record her ID, birth date, parentage if known, dates of breeding, the male used, expected due date, birth date, litter or birth outcome and notes on the mother's health and behavior.
For each offspring, record its ID, sex, birth date, birth weight if taken, parents and any problems. Add weaning dates and later notes on growth and health.
Keep the format the same each year so you can compare. Include the date you last saw each female in good health, because it helps your vet if you need to estimate timing later. If you purchase animals, keep their seller's records and ask for anything missing, since earlier history helps you plan.
How do I track heat, breeding dates and due dates?
Each species has its own cycle and gestation length, and these differ among breeds and individuals. Ask your vet or extension office for the expected timing for your animals rather than relying on general numbers.
Write down dates you observe heat, dates of mating or insemination and the due date your vet or extension office gives you. A wall calendar helps you see what is coming.
Note any signs of problems, and call your vet if a female does not conceive or shows trouble. Heat signs can be subtle in some species, so ask experienced keepers what they watch for and write down what you see.
How do records help me choose breeding stock?
Over time, records show which females raise healthy young, which grow well and which cause trouble. Use them to choose animals to keep, to sell or to retire.
Look at patterns, not single events. One bad season may be weather or luck, but repeated trouble may point to a problem with the animal or the pairing.
Ask your vet or extension office for advice on traits to watch for in your species. Ask your vet whether fertility checks or health exams before breeding make sense for your animals and your goals.
- Which females raise healthy young
- Which young grow well
- Repeated problems with a pairing
- Temperament and ease of handling
What about inbreeding and genetic problems?
Breeding closely related animals can raise the chance of inherited problems. Records of parents and grandparents help you avoid pairing close relatives by accident.
Ask your breed association or extension office about pedigree tools and breed concerns. Some breeds have known health issues, and testing may be available through your vet.
Do not guess about genetic problems. A vet or breed expert can advise based on evidence. A written pedigree also helps when you sell breeding stock, since buyers often ask who the parents were.
How should I plan for birthing season?
Use your due dates to plan labor, housing and your own schedule. Prepare clean birthing areas, check supplies with your vet and arrange backup help.
Post your vet's phone number and know when to call. Do not attempt home procedures unless a vet has trained you.
Keep notes on each birth, including time, any help given and the health of mother and young. Plan to be present or on call around the expected dates, and arrange backup help if you have a job or travel plans.
What rules apply to breeding and selling animals?
Rules for registration, health certificates, movement and sales vary by state and species. Breed associations have their own registration rules.
Ask your state department of agriculture and state veterinarian what applies to selling or moving breeding animals, and your breed association about registration.
Keep papers from sales and purchases with your records. Registration papers and health records are often requested together, so keep them in the same folder.
How do I keep records simple enough to last?
Use one form or sheet for all animals, and fill it in the same way each time. Keep it where you do chores, and back it up.
Review each season, and drop fields you never use. A short record you keep up beats a long one you abandon.
Share the system with anyone who helps with the herd, so notes stay consistent. Walk through a mock season on paper before you begin, listing every date and note you would want, then trim the list.
Key takeaways
- Record each mating, due date, birth and offspring in a consistent format.
- Use your vet or extension office for expected timing in your species.
- Look for patterns across seasons when choosing breeding stock.
- Check state rules and breed association rules before selling or registering animals.
