Tag Identity and Breeding Lines
Give every Dorper a record tied to its ear tag: birth date, sire, dam, and whether it was born a single, twin, or triplet. Dorper flocks are often run commercially with lambs moving on quickly, which makes early recording essential; a lamb whose parentage was never written down cannot be kept as informed breeding stock later. Note which ewes' lambs you retain, so replacement ewe lambs trace back to mothers whose performance you actually know.
Lambing Records for Ewes
For each ewe, log the breeding group and ram, lambing date, number of lambs born and weaned, and any lambing difficulty or poor mothering. Dorpers are promoted for fertility and lambing ease, and your own records are how you verify those claims in your conditions rather than in a sale catalogue. A ewe that twins reliably on pasture and rears both is worth more to your flock than her looks suggest, and only the lambing book proves it season after season.
Growth Weights Instead of Wool Records
Dorpers are hair sheep that shed their covering, so your performance records centre on weight rather than fleece. Record weaning weights and a later market or joining weight, taken consistently across the group. Note lambs that lag despite good feed, and connect those notes to health entries, because slow growth in a shedding meat breed often traces back to parasites or a lambing problem rather than genetics alone.
Parasite, Hoof, and Health Notes
Keep dates and findings for parasite monitoring, hoof trimming, and any treatments, filed by tag number. Dorpers have a reputation for parasite resilience, but resilient individuals vary, and records of which sheep repeatedly need treatment identify the ones to cull from a breeding flock aiming for low inputs. Record deaths with the suspected cause and weather or pasture context; patterns across a season are far easier to see in a written log than from memory.
Ram and Sale Records
Log which ram ran with which ewes and for how long, any ram soundness checks, and sale dates, weights, and destinations for finished lambs. Those sale results close the loop: the ewes whose lambs finish fastest on your pasture are the ones your records should be steering you to keep.
Using Dorper Records Across the Season
The value of a Dorper record book shows up at three moments: joining, lambing, and weaning. Before joining, read back each ewe's previous lambing result, her last weight, and whether she needed parasite treatment during the previous season, and let that decide who goes to the ram and who is sold instead. At lambing, a short daily note of which ewes lambed and how many lambs are at foot prevents mismothering confusion in a flock where many lambs arrive close together. At weaning, pair each lamb's weight with its dam's record before you choose replacements. Handled this way, the same small set of entries is consulted three times a year and steadily replaces guesswork about which ewes are carrying the flock and which are being carried by it.
A KinsLe Pet Passport can carry each Dorper's tag identity, lambing history, weights, and health notes as one portable packet, useful at sales, vet visits, and breeding reviews.
