Practical skills for the barn — blood draws, injections, splinting, breeding soundness, vaccination, and the medicine cabinet. Presented at the Black Sheep Gathering Gotland Show.
This is a take-home reference for hands-on barn skills: drawing blood, giving injections, splinting a contracted-tendon lamb, running a pre-breeding soundness check, building a sensible vaccine plan, and stocking a medicine cabinet you will actually reach for. Where doses, products, or schedules appear, they are general guidance only. Always read and follow the product label for dose, route, and withdrawal time, and partner with your own veterinarian — especially for prescription products, anything given to a pregnant animal, and anything entering the food chain.
Before you can spot trouble, you need a baseline. Take a resting temperature, pulse, and respiration on a few healthy animals so you know what normal looks and feels like in your own flock.
| Vital Sign | Normal Adult Sheep Range |
|---|---|
| Temperature | 101.5 to 103.5°F (average near 102.3). A hot day, handling, or stress can push it up. |
| Heart rate | 70 to 90 beats per minute (faster in lambs). |
| Respiration | 12 to 20 breaths per minute at rest. |
| Rumen motility | 1 to 2 contractions per minute. Listen at the left flank. |
| Mucous membranes | Moist and pink. Use FAMACHA scoring to screen the lower eyelid for anemia from parasites. |
| Body condition | Score on a 1 to 5 scale. Most breeding animals do best near 3 to 3.5. |
A good medicine cabinet is organized, in date, and stocked before you need it. An emergency is never the moment to discover an empty bottle. Build the kit below, store it clean and dry, keep cold-chain items in the refrigerator, and check expiration dates each season.
| Category | What to Stock | Notes |
|---|---|---|
| Vitals & exam | Digital thermometer, stethoscope, exam light, scale, marking crayon, records notebook. | You cannot treat what you cannot measure. |
| Injecting & dosing | Syringes (1 to 20 mL), needles (18 to 20 ga, 1/2 to 1 in), drench or dosing syringe, sharps container. | New, sterile needle for every animal. Single use only. |
| Core vaccines | CDT (Clostridium C and D plus Tetanus). Add abortion vaccines if your vet advises. | Keep cold, watch dates, do not freeze. |
| Parasite control | FAMACHA card, dewormers from more than one drug class, coccidiostat, fecal sample kit. | Treat by need and fecal results, not the calendar. |
| Metabolic support | Oral propylene glycol (energy), oral calcium, electrolytes, B-complex and thiamine, probiotic paste. | Often emergency items. Use under veterinary direction. |
| Wound & hoof | Chlorhexidine or iodine scrub, wound spray, vet wrap, gauze, bandage scissors, hoof trimmers, hoof rot treatment. | Clean the area before you treat it. |
| Restraint & ID | Halter, ear tagger and tags, elastrator and bands or Burdizzo, nitrile and OB gloves. | Plan tetanus protection any time you band. |
| Prescription & pain | Antibiotics and anti-inflammatory or pain medication as prescribed for your flock. | Prescription only. Follow label dose and withdrawal. |
Many antibiotics now require a veterinary prescription or a feed directive. Record every product, lot number, dose, route, date, and the animal treated. Honor all meat and milk withdrawal times. When in doubt, call your veterinarian first.
Some of what belongs in a good cabinet you can still buy off the shelf, and the rest now goes through your veterinarian. A 2023 federal rule (FDA Guidance 263) moved nearly every injectable and oral antibiotic — oxytetracycline and penicillin included — from over the counter to prescription only. Plan to source those through your vet, and build that relationship before you need it.
These need a current veterinary relationship. Ask your vet to set you up ahead of need, with the dose, route, and withdrawal time written on each label.
| Ask Your Vet | Why It Earns a Spot |
|---|---|
| Meloxicam tablets | An oral anti-inflammatory and pain reliever. A standout for banding and castration pain, tail docking, and lameness. Long acting and easy to give. |
| Ampicillin or Penicillin G | Injectable antibiotics for bacterial infection, now prescription only. Your vet guides the choice, the dose, and the meat and milk withdrawal time. |
| Oxytetracycline (LA-200) | A broad-spectrum injectable for pinkeye, foot rot, and respiratory infection. The classic OTC antibiotic, now prescription only since 2023. |
| Silver sulfadiazine cream | A topical antibacterial for burns, raw wounds, and skin infections. Keeps the wound bed moist, clean, and protected while it heals. |
| Bo-Se (selenium & vitamin E) | For white muscle disease on selenium-deficient ground. Prescription only, and only where your soil and forage call for it. Your vet confirms whether your area qualifies. |
| Over the Counter | Why It Earns a Spot |
|---|---|
| Thiamine & B-complex | B vitamins for appetite, rumen function, and nerve support. Fortified B-complex is easy to find; ask your vet about prescription-strength thiamine, the front-line treatment for polio. |
| Corid (amprolium) | Treats and prevents coccidiosis, a common cause of scours in young stock. Not an antibiotic. Follow the label closely, since long courses can work against thiamine. |
| Dewormers for your area | Anthelmintics chosen for the parasites and resistance patterns in your region. Use FAMACHA and fecal counts to deworm by need, and ask your vet which classes still work locally. |
| Children's gas drops | Simethicone to break up frothy gas. A gentle first response for mild gas and bloat discomfort while you assess the animal. |
| Therabloat (poloxalene) | A targeted anti-bloat drench for frothy or pasture bloat. The stronger tool to have ready when gas drops are not enough and minutes matter. |
| Aluspray | An aerosol aluminum bandage that seals and protects wounds and post-procedure sites from dirt and flies. Sprays on where a wrap will not stay. |
| Catron IV | An insecticidal wound spray. Protects open wounds from flies and treats fly strike and maggots in warm weather. |
| Fleet enemas | For constipated lambs. Gentle, ready relief for a lamb that is impacted or straining. |
| Vetericyn eye gel | An antimicrobial ophthalmic gel for pinkeye, irritation, and minor eye injuries. Soothes and protects the eye without a sting. |
Most sheep medications are given either under the skin (subcutaneous, SQ) or into the muscle (intramuscular, IM). The label tells you which. Giving an SQ product into muscle, or the reverse, can cause poor results or tissue damage, so always check the route before you draw it up.
| Route | Needle | Best Site | Key Points |
|---|---|---|---|
| SQ (under the skin) | 18 to 20 ga, 1/2 to 3/4 in | Loose skin over the neck, behind the elbow, or over the ribs. | Tent the skin, slide the needle into the tent, draw back, then inject. Preferred when the label allows, since it is gentler on tissue. |
| IM (into muscle) | 18 to 20 ga, 1 to 1 1/2 in | The muscle of the neck, ahead of the shoulder and below the crest. | Insert firmly, draw back to be sure you are not in a vein, then inject slowly. Keep to about 5 mL per site and split larger volumes. Favor the neck to protect valuable cuts. |
A small, firm swelling at the site is a common local reaction that usually fades. Watch for heat, pain, abscess, or a sick animal, and call your vet if those appear. Favoring SQ over IM when the label allows, and rotating sites, keeps reactions and carcass blemishes to a minimum.
A clean jugular blood sample lets you test for disease, confirm pregnancy, and check mineral or metabolic status. The jugular vein runs in the groove along each side of the neck and is the standard site in sheep.
| Tube Top | Additive | Common Use |
|---|---|---|
| Red | None (serum) | Serology such as OPP, Brucella ovis, and Johne's, plus chemistry and mineral panels. |
| Tiger or gold (SST) | Clot activator and gel | Serum tests with faster, cleaner separation. |
| Purple (lavender) | EDTA anticoagulant | Complete blood count, many PCR tests, and usually the right tube for pregnancy testing. |
No flow usually means the needle slipped off or through the vein, or suction collapsed it. Ease back, re-occlude, and redirect rather than digging. Let vacuum tubes fill at their own pace. A swelling during the draw is a hematoma: stop, apply pressure, and try the other side.
Some lambs arrive unable to straighten the lower front legs. They knuckle forward at the fetlock or walk on the front of the pasterns. Mild cases often correct on their own with a little help. Moderate to severe cases need a splint to hold the leg in a better position while the tendon stretches and gains strength.
For a mild case, support the lamb so it can stand and nurse, and gently extend the leg several times a day. Many straighten within a few days. Reach for a splint when the lamb cannot bear weight correctly, knuckles fully over, or is not improving with stretching alone.
You will need: a first-aid foam-wrapped aluminum splint (the malleable, foam-padded kind that bends to fit the leg), a little extra padding for bony points, cohesive bandage (vet wrap), and scissors.
Check the splint several times a day for swelling, coldness, or color change in the exposed toes, and for any rub sores. Re-pad and re-wrap every day or two, and take the splint off briefly for gentle stretching. Most lambs improve within days to a couple of weeks; wean off the splint as the leg holds on its own. If a joint is involved, sores develop, or there is no progress, call your vet, who can also check for a selenium or vitamin E deficiency.
A breeding animal that cannot travel, eat, or carry condition will not produce a strong lamb crop. Examine rams and ewes 6 to 8 weeks before breeding so you have time to correct problems, adjust nutrition, treat feet, or replace an animal that does not pass.
The ram is half of every lamb in the flock, so he earns the closest look. A sound ram is fit, structurally correct, and fertile.
A sound, mature ram can cover roughly 35 to 50 ewes in natural service. Lower that ratio for ram lambs, large or rough pastures, and short, tight breeding windows. Always run more than the bare minimum of rams when you can.
Ewes should enter breeding healthy, structurally sound, and on a rising plane of nutrition.
Pre-breeding is the moment to give any abortion-prevention vaccines your veterinarian recommends and to settle mineral status. Decisions made 6 to 8 weeks out show up as a tighter, healthier lamb crop the following season.
Vaccination is cheap insurance against diseases that kill quickly. The cornerstone for nearly every flock is CDT, which protects against Clostridium perfringens types C and D (enterotoxemia, or overeating disease) and tetanus. A broader 8-way clostridial vaccine such as Covexin 8 can be used in its place where you want wider coverage. Build your program around one of these, then add regional vaccines on your veterinarian's advice.
| Animal or Stage | Core Vaccine | Timing |
|---|---|---|
| Naive adult (ewe or ram) | CDT | Two doses 3 to 4 weeks apart, then a yearly booster. |
| Pregnant ewe | CDT booster | 4 to 6 weeks before she is due, so protective antibodies pass to the newborn. |
| Ram | CDT booster | Once a year, conveniently at the pre-breeding check. |
| Lamb from a vaccinated dam | CDT | First dose at about 6 to 8 weeks, booster 3 to 4 weeks later. |
| Lamb from an unvaccinated dam | CDT plus tetanus protection | Start the CDT series earlier, and give tetanus antitoxin at docking or banding for immediate cover. |
Add these only when your history and your veterinarian point to a real risk in your area. They are not core for every flock.
Store vaccines cold and never frozen, and check expiration dates. Do not vaccinate sick or heavily stressed animals. Give CDT and most sheep vaccines under the skin (SQ) in the neck. Boosters matter: a single first dose primes the immune system, but the second dose is what builds real protection. Keep written records of product, lot, date, and animal.
