Merino sheep should receive a veterinary check at least once a year, and the smartest timing is around shearing, when the fleece that hides almost everything about this breed is finally off. Merinos are kept for exceptionally fine, dense wool, and that wool is both their value and their veterinary complication: it conceals body condition, hides skin lesions and flystrike until they are severe, grows over the eyes of heavily wooled sheep, and keeps the skin warm and damp in exactly the way parasites and blowflies prefer. An annual check built around the shearing calendar, plus prompt visits for strike and lambing trouble, is the realistic standard for the breed.
Seeing the Sheep Under the Fleece
During the annual check, insist on hands-on condition scoring of a proper sample of the flock, not a glance at woolly outlines — a Merino in full fleece can be a skeleton in a duvet. Skin inspection is the second priority unique to the breed: part the wool on the back, belly, and breech looking for the crusting, irritation, and discolouration that signal skin parasites or early strike, because by the time a struck sheep shows restlessness and a dark, foul patch, maggots have been working for days. Eyes matter too — woolly-faced Merinos can become effectively blinded by fleece growing over the face, and the vet can judge which sheep need their vision cleared regularly and check for the eye infections that follow dust and grass seeds trapped in facial wool.
Flystrike and Feet Shape the Extra Visits
In warm, humid weather, treat a restless Merino — stamping, tail-wagging, biting at its breech, or standing apart with a stained patch of wool — as a likely strike case needing attention that day, with the vet involved for extensive strikes, deep wounds, or a sheep that is dull and off feed. Crutching and dagging schedules should be reviewed with the vet, since clean breeches are strike prevention, not cosmetics. Feet also drive unscheduled work: Merinos on wet ground are prone to foot troubles that spread through a flock, so a rising number of lame sheep is a flock appointment, not a series of individual shrugs. Rams deserve a pre-joining soundness check, and ewes in difficulty at lambing, or scouring lambs, follow the usual rule — seen in days, not at the next muster.
Parasites, Nutrition, and the Fine-Wool Balance
Fine-wool production makes its own nutritional demands, and the annual visit is the moment to review whether condition, wool quality, and lambing performance suggest the ration and minerals are meeting them. Faecal testing guides worm advice for your pastures, and the vet can help you read whether dags, scouring, and poor growth are a parasite story, a feed story, or both at once. Bring your shearing records: fleece weights and quality by age group turn the conversation from impressions into evidence, and a drop in fleece performance across the flock is itself a health finding worth investigating rather than a disappointment to accept.
Records That Follow the Fleece Cycle
Because so much Merino care is seasonal, notes tied to shearing, crutching, lambing, strike cases, and treatments are most useful kept per mob and per standout animal. Gathered in KinsLe with Pet Passport, those entries let the vet walk into shearing week already knowing which ewes struck last season and which lambs struggled, instead of rediscovering it sheep by sheep.
