What records should I keep for my Merino sheep?

Published October 28, 2026

The short answer

For Merino sheep, keep tag-linked records of birth date, sire and dam, shearing dates, individual fleece weights and wool quality assessments, and lambing history, because the fleece is this breed's main product. Add weights, skin and flystrike observations, parasite and health treatments, breeding groups, and wool sale results by bale or lot. Fine-wool breeding decisions depend on fleece data you cannot judge by eye alone. KinsLe's Pet Passport can keep each Merino's fleece, breeding, and health records together in one portable packet.

Identity and Bloodline Records

Anchor each Merino's record to its ear tag, with birth date, sire, dam, and birth type, and file stud registration papers for registered animals. Merino bloodlines are traded on documented fleece performance, so the link between a sheep and its measured wool results is commercially important, not just tidy. Record purchases with the stud or flock of origin, and note any sheep bought in specifically to shift fleece traits in a particular direction.

Fleece Records at Every Shearing

Shearing is the harvest, so record the date, the individual fleece weight where you weigh fleeces, and quality assessments such as fineness, staple length, colour, and faults noted by the wool classer. Keep mid-side sample results with the sheep's own record when you test, because breeding for finer wool from memory produces flocks that drift coarser while looking unchanged. Note which sheep were crutched or wigged between shearings and why, since those interventions affect both fleece presentation and the skin problems described below.

Lambing and Reproduction History

For each ewe, log the ram and joining dates, lambing date, lambs born and weaned, and mothering notes. Merino ewes are not always the easiest lambers or mothers compared with maternal breeds, which makes honest records essential: a ewe combining a valuable fleece with reliable lamb rearing is rare and worth identifying, while a fine-woolled ewe that repeatedly fails to rear a lamb is quietly costing the flock money her fleece figures conceal.

Skin, Flystrike, and Health Observations

Record skin wrinkle observations in young sheep, any flystrike occurrence with its location and date, crutching and shearing wounds, and treatments given. Patterns matter here: strike in the same body region across related sheep is breeding information, and strike following particular weather or pasture conditions is management information. Log vaccinations, parasite treatments, hoof care, and other illnesses by tag and date alongside those skin notes, so the health picture for each animal is complete in one place.

Wool Sales and Flock Outcomes

Close the loop with wool sale results recorded by lot or bale, linked back to the shearing and classing notes that produced them, plus sale, cull, and death records with reasons. Returns achieved for a well-documented clip are the final test of whether your fleece records have been steering breeding in a profitable direction.

Linking Merino Lamb Records to Future Fleeces

The fleece a Merino grows as an adult begins with decisions recorded at lambing, so keep the lamb's early file connected to its first shearing result. Note birth type, any slow start, and the dam's fleece assessment beside the lamb's identity, then add its hogget fleece weight and classing comments when that first clip comes off. Sheep that were twins, or that struggled early, often cut lighter first fleeces for reasons that have nothing to do with their breeding value, and without the birth note they are judged unfairly and may be culled for the wrong cause. Over several drops, these linked records show which sire lines hold their fineness as the sheep mature and which produce impressive young fleeces that coarsen early, a distinction no single shearing day can reveal on its own.

With a KinsLe Pet Passport, each Merino's fleece measurements, lambing history, skin notes, and health record travel together in one portable packet for classers, vets, and stud buyers.
