| Alert | Detail |
|---|---|
| BO-SE is CONTRAINDICATED in pregnant ewes | Injectable selenium/vitamin E has caused deaths and abortions. Use oral mineral supplementation instead. BO-SE can be given to lambs at 2+ weeks of age. |
| Hypothermia: Age matters | Lambs under 5 hours old: warm first, then feed. Lambs over 5 hours old with severe hypothermia: give intraperitoneal glucose BEFORE warming — warming without energy causes fatal seizures. |
| Treat for BOTH | Hypocalcemia and pregnancy toxemia look identical. Treat for both simultaneously — the treatments don't interfere. |
| Never pull a retained placenta | Pulling risks uterine hemorrhage. It will pass on its own; call vet if ewe shows signs of infection. |
| Pregnant women must NOT assist lambing | Risk of toxoplasmosis, enzootic abortion, Q fever. Always wear gloves. |
Assemble this kit at least 2 weeks before the first expected lambing date.

Calculate due dates: Katahdin gestation averages 147 days (range 142-152). If ram went in November 18 -> first possible lambs ~April 9; expected due date ~April 14. Have barn fully ready by day 140 from ram introduction.
70% of fetal growth occurs in the last 6 weeks. Ewes cannot physically eat enough forage to meet energy demands alone.
| Situation | Grain Introduction | Target BCS |
|---|---|---|
| Ewes carrying multiples | Start 4-6 weeks pre-lambing | 3.5-4.0 |
| Ewes carrying singles | Start 2-3 weeks pre-lambing | 3.0-3.5 |
Grain schedule:
- Start at 0.5 lb/day, increase gradually over 2 weeks
- Target: ~1 lb grain per lamb carried per day (1-1.5 lbs singles, 1.5-2 lbs twins)
- Never increase more than 0.25 lb/day (acidosis risk)
- Katahdins are easy keepers — do NOT overfeed. BCS above 4.0-4.5 increases pregnancy toxemia risk
Hay & forage: Good quality grass hay free-choice. Introduce alfalfa hay around day 90 of gestation for calcium; gradually increase proportion.
Water: 1-4 gallons per ewe per day. Keep water above 40°F to encourage consumption. Inadequate water = reduced feed intake = pregnancy toxemia trigger.
Minerals: Sheep-specific loose mineral free-choice (NOT goat or cattle — copper levels differ). Maintain Ca:P ratio above 1.5:1. Katahdins tolerate more copper than wool breeds but toxicity is still documented — use sheep minerals.
Many eastern US regions have selenium-deficient soils, causing white muscle disease in lambs.
Safe approach for pregnant ewes:
- Free-choice loose mineral with selenium year-round (FDA max 90 ppm in mineral)
- Top-dress vitamin E on grain: 100 IU per ewe per day per lamb carried
- Selenium/iodine premix mixed 1 lb to 50 lbs plain salt
- DO NOT inject BO-SE in pregnant ewes — deaths reported
- Have hay/soil tested to know your baseline selenium levels
Vaccinate all ewes with CDT (Clostridium perfringens C & D + tetanus) 4-6 weeks before lambing.
- First-time mothers: TWO shots — first at 6 weeks pre-lambing, booster at 3 weeks
- Experienced ewes: One annual booster at 4-6 weeks pre-lambing
- This transfers passive immunity to lambs via colostrum for 6-8 weeks
Lambing jugs: 5'x5' (minimum 4'x4'), sides at least 3 feet high, moveable panels. Plan 1-2 jugs per 10 ewes. Each needs: flat-backed water bucket, feed tray, hay bag.
Bedding: 4-6" granular field-grade limestone on floor (NOT powdered), covered with 6-8" clean straw. Straw is preferred over shavings (better footing for newborns, lower mastitis risk). Refresh between each ewe.
Ventilation: Air movement HIGH (above animal level), not at bedding level. Lambs tolerate cold better than drafts and dampness. Prioritize dry over warm.
Lighting: Red or dim options for night checks. Full overhead lights disturb laboring ewes.
- Mud management: Gravel/wood chips in high-traffic areas. Avoid low-lying paddocks.
- Predator protection: Walk fence lines 2-3 weeks before. Livestock guardian dogs, donkeys, or llamas. Night confinement near barn during peak lambing.
- Separate groups: Still-to-lamb ewes | Recently-lambed pairs | Older pairs ready for main flock
- Barn camera with night vision (IR LEDs) — Reolink Argus 3 Pro, Eufy SoloCam E40, or Wyze cam on hotspot ($30-50)
- Audio capability helps distinguish labor from restlessness
- Baby monitor works for barns close to house
Check every ewe:
- BCS — At target? Adjust feed if needed
- Udder — Developing? Asymmetric/hard = possible mastitis history
- Feet — Trim hooves. Lame ewe can't position for delivery
- Vulva — Signs of vaginal prolapse?
- Tag — Can you read her ID?
- CDT — Done 4+ weeks ago?
- Deworming — FAMACHA score? Strategic treatment only
| Sign | What to look for |
|---|---|
| Udder | Firm, tight, shiny. Teats swollen and filled. "Tight as a drum" = 24-48 hours. Easy to see on Katahdins (no wool). |
| Vulva | Swollen, elongated, pinkish/reddish. Possible clear/whitish mucus discharge. |
| Ligaments | Feel beside the tailhead — when you can wrap your fingers around with no resistance = 12-24 hours. |
| Flanks | Appear hollow/sunken as lambs "drop" into position. |
| Behavior | Restlessness, pawing, nesting, separating from flock, lying down/standing repeatedly, looking at flanks, lip curling, loss of appetite within 3 hours of labor. |
- Uterine contractions NOT visible as pushing
- Ewe shifts position, paws ground, lies down/stands
- Thick mucus string from vulva
- Contractions every 15 min initially → every 2-3 min
- DO NOT disturb the ewe during this stage. Moving her to a jug during early labor increases cervical problems.
- Water bag appears or ruptures
- Active, visible pushing begins
- Normal sequence: water bag → front feet (soles down) → nose on legs → head → shoulders → body
- A normal delivery takes 5-10 minutes once engaged
- For multiples: expect 10-60 minutes between each lamb
- Katahdins normally deliver quickly and without help
Two front feet extending, soles facing DOWN, nose/head resting on top of the legs between the knees.
How to confirm: Feel two feet with soles pointing down. Following the legs back, find the nose between them. Front legs bend the SAME direction at knee and fetlock. If joints bend OPPOSITE directions — those are hind legs (backward presentation).
- Uterus continues contracting (less intensely)
- Normal: 2-3 hours, acceptable up to 6-8 hours
- NEVER pull on a hanging placenta — hemorrhage risk
- Nursing triggers oxytocin which helps natural expulsion
- Remove expelled placenta from lambing area
- Retained if not passed by 12-18 hours → monitor, contact vet if ewe shows illness
| Trigger | Action |
|---|---|
| 30 min after water bag, no feet visible | Check the ewe |
| 30 min of active pushing, no progress | Intervene |
| 20+ min straining, nothing visible | Investigate (Katahdin breeders use this shorter threshold — Katahdins deliver fast when things are right) |
| Stage 1 > 8 hours | Check |
| Water bag visible 1+ hour, no pushing | Check |
| Ewe exhausted, gives up, severe distress | Intervene |
- Restrain ewe (halter or helper, hog panels work well)
- Wash rear end with warm water + mild disinfectant
- Wash hands/arms with surgical scrub
- Wear arm-length OB gloves
- Generous water-based OB lubricant on hand and vulva
- Always wear gloves — zoonotic disease risk
With a clean, lubricated gloved hand, reach toward the cervix. If you cannot pass your hand through = cervix not fully dilated = DO NOT attempt to pull a lamb. If partially dilated (ringwomb), try gentle manual stretching with a "duck bill" hand for up to 30 minutes. If this fails → call vet (C-section may be needed).
- Grasp both front legs above the fetlock joints
- Pull ONLY when the ewe strains — with her contractions
- Pull in a downward arc (out and DOWN) following the birth canal curve
- Slow, steady traction over 10-30 seconds per pull
- After thorax clears, rotate lamb ~30 degrees to prevent hip lock
- Tip: Pull lamb only halfway out (past shoulders), let ewe deliver hindquarters herself — improves bonding
- Leave lamb at ewe's head for bonding
- Pinch between toes → live lamb pulls foot away
- Finger in mouth → live lamb has suckle reflex
- Touch back of throat → gag reflex
- All three absent = likely dead
Push head back slightly, trace visible leg to shoulder, find the other shoulder, follow retained leg down, cup foot in palm, extend fetlock and elbow into birth canal. Deliver normally.
Head swells rapidly. Push head back gently with lubricant (patience if swollen). Bring each leg forward one at a time. Tube feed colostrum after delivery — swollen head/tongue impairs nursing.
Attach OB chains/ropes to front legs FIRST (so you don't lose them). Push lamb back, find head, guide it around between legs. Wire head snare behind ears helps control the head. Extra lubricant essential.
Two feet with soles pointing toward ewe's spine, hock joints bend opposite to fetlocks. Deliver QUICKLY — umbilical cord breaks before head emerges, lamb tries to breathe while head is inside. Secure tail with hind legs, apply steady fast traction. Once hips clear, deliver rest rapidly.
Rump lodged in pelvic inlet, both hind legs forward. One of the most dangerous presentations. Push lamb back, flex stifle/hock/fetlock while cupping each foot to protect uterus, bring hind legs into canal one at a time. High risk of uterine rupture. If not confident → CALL VET.
More than two feet or confusing mix. Stay calm. Trace each leg: front legs = knee and fetlock bend same direction; hind legs = hock and fetlock bend opposite. Identify which legs belong to which lamb. Attach ropes to the first lamb's legs, push the other back, deliver first, second follows easily.
- Clear airways — wipe nose/mouth with clean towel. Rub chest vigorously to stimulate breathing. Hold briefly by hind legs to drain fluid if not breathing. Let the ewe lick and bond.
- Dip navel — 7% iodine or chlorhexidine 2-4% within 15-30 minutes. Use a dip cup, not a spray bottle. Re-dip at 12 hours. Prevents navel ill, joint ill, septicemia.
- Strip teats — Check ewe has milk in both teats by stripping each one. Remove wax plugs.
| Timeline | Target |
|---|---|
| First 1-2 hours | 50 mL/kg body weight (~6 oz for an 8-lb twin) |
| First 24 hours | 200-250 mL/kg (~24-30 oz for an 8-lb twin), split across 4+ feedings |
- Gut absorption of antibodies is highest in first hours, closes by 12-24 hours
- Healthy Katahdin lambs should be on feet within 10-20 minutes, seeking teat within 30 minutes
- If lamb hasn't nursed within 1 hour → intervene with bottle or tube
Priority order for colostrum source:
- Own dam's colostrum (best — contains farm-specific antibodies)
- Another ewe's fresh/frozen colostrum
- Cow or goat colostrum
- Commercial replacer (last resort — NOT adequately tested in lambs)
Frozen colostrum banking: Collect surplus from heavy milkers. Freeze in 50 mL portions (ice cube trays or zip-locks laid flat). Good for 6 months. Thaw in warm water bath at 104°F — NEVER microwave (destroys antibodies).
Brix refractometer: 22%+ = adequate quality. 26.5% = optimal cutoff. Below 22% = poor, supplement or replace.
When to tube: Lamb too weak to suck but can swallow; won't latch despite being alert; hypothermic but conscious.
NEVER tube: Unconscious lamb, lamb that cannot swallow, severely hypothermic lamb with cold mouth (warm first).
Technique:
- Warm colostrum to 104°F
- Measure tube on outside of lamb: mouth to last rib. Mark insertion depth.
- Insert gently along LEFT side of neck — lamb should swallow it
- Safety check: Attach syringe, pull back plunger. Strong resistance = stomach (correct). Easy movement = trachea (WRONG — remove immediately)
- Deliver slowly. Volume: 50 mL/kg per feeding (~6 oz for 8-lb lamb)
- For very weak lambs: 50 mL every 2 hours
Mid-April in temperate US: nights 30s-40s°F, days 55-65°F. Newborn lamb lower critical temp is 50°F.
- Katahdin advantage: Hair coat repels water, lambs dry faster than wool breeds
- Still dangerous: Wet newborn in 35°F wind → hypothermic in 30-60 minutes
- First 5 hours (while birth fluids dry) = highest risk period
- Deep straw bedding (12+ inches) + windbreak may be sufficient for healthy, nursed Katahdin lambs
- Have warming box ready for any lamb slow to get going
- All lambs MUST get colostrum from the dam in the first 2 hours
- Assist smallest/weakest to nurse first while stronger siblings rest
- Triplet decision: Within hours of birth — keep all three on ewe (only if proven heavy milker in excellent condition) OR remove smallest for supplemental feeding/fostering
- If keeping all three: supplemental bottle feedings 3-4x daily; monitor belly fill on all three at every check
- Mothering pen (jug) for 12-24 hours minimum for bonding
| Time | Checks |
|---|---|
| 0-1 hr | Clear airways, let ewe bond, dip navel, assist nursing if needed, weigh lamb, record birth details |
| 1-2 hr | Confirm first nursing (belly fill check). Strip each teat. Bottle/tube if no nursing. |
| 2-6 hr | Second belly check. Re-dip navel. Check for entropion, contracted tendons. Ewe eating/drinking? |
| 6-12 hr | Third belly check. Tube feed if needed. Monitor meconium passage. |
| 12-24 hr | Continue 3-4 hour checks. Total colostrum should reach 200-250 mL/kg. Meconium should have passed. |
| 24-48 hr | Move to mixing pen if bonding solid. Watch for scours, navel swelling, eye issues. Weigh — should be gaining. |
| 48-72 hr | Lamb should be thriving — gaining weight, active, nursing confidently. Any lamb still struggling → vet. |
| Birth type | Birth weight | Daily gain target |
|---|---|---|
| Singles | 9-10 lbs | 0.5-0.75 lb/day |
| Twins | 7-8 lbs | 0.5-0.75 lb/day |
| Triplets | 6-7 lbs | 0.5-0.75 lb/day |
Weight loss >10% of birth weight in first 24 hours = red flag.
Entropion (inverted eyelids): Most common eye problem. Check all lambs within 24 hours. Signs: excessive tearing, squinting. Mild: roll eyelid outward + antibiotic ointment. Moderate: SQ injection of penicillin into lower eyelid (creates corrective swelling). Do NOT keep affected ewe lambs as breeding stock.
Contracted tendons: Lamb walks on knuckles. Mild cases self-correct in 24-48 hours. Moderate: splint with tongue depressors + vet wrap for 2-3 days.
Cleft palate: Check by feeling roof of mouth. Lamb cannot nurse effectively. Usually not viable.
| Severity | Temp | Signs |
|---|---|---|
| Normal | 102-103°F | Alert, active |
| Mild | 99-101°F | Chilled but conscious, shivering, can suckle. Ears cool. |
| Moderate | 95-99°F | Weak, reluctant to stand, can't suckle. Ears curled. Lethargic. |
| Severe | Below 95°F | Recumbent, cold mouth, no suckle reflex, ears stiff and curled. EMERGENCY. |
Quick field check: Put finger in lamb's mouth. Warm = OK. Cool = mild. Cold = severe — act NOW.

1. Dry thoroughly 1. IP GLUCOSE FIRST
2. Warm in box (10 mL/kg of 20%
to 99°F dextrose, inject
3. Tube colostrum 1" below navel)
once warm 2. THEN warm in box
4. Return to ewe 3. Tube colostrum
once revived
4. Return to ewe
IP Glucose Injection: Site: 1 inch below navel, 0.5 inch to side. Needle: 20g x 1-1.5". Angle toward tail at 45°. Mix: 2 parts 50% dextrose to 3 parts boiled water = 20% solution. Dose: 10 mL/kg body weight. Have your vet demonstrate this before lambing season.
- Insulated box, large enough for 1-2 lambs
- Air temp 99-104°F — NEVER exceed 104°F
- Thermometer visible from outside
- Ventilation holes (lamb needs fresh air)
- Check rectal temp every 15-30 min
- Remove lamb once temp reaches 99°F
Heat lamps are the #1 cause of barn fires.
- Secure with chain and locking connector — NEVER twine/rope/wire
- Minimum 20 inches from any surface
- Use shielded livestock lamps (thick glass)
- One lamp per outlet (no overloading)
- Safer alternatives: ceramic heat emitters, radiant panel heaters, heated mats
The most important metabolic emergency to prevent.
| Stage | Signs | Treatment |
|---|---|---|
| Early | Off feed, lagging behind, sweet breath | Propylene glycol 60 mL orally every 12 hours |
| Moderate | Teeth grinding, star-gazing, tremors, unsteady | Propylene glycol + CMPK + vet consult |
| Severe | Unable to rise, blind, seizures | IV dextrose by vet; C-section may be only option |
Prevention: Adequate grain in last 6 weeks. BCS 3.0-3.5 at lambing. Don't let pregnant ewes go off feed. Fat ewes (BCS >4) are at HIGHEST risk.
Usually late pregnancy or early lactation. Symptoms: stiff gait → weakness → recumbency → coma.
Treatment: Calcium borogluconate 23% subcutaneously (50-60 mL divided across 2 injection sites). CMPK drench orally. Response usually rapid (within hours). Avoid calcium chloride — burns mouth/throat.
Practical approach when unsure: Treat for BOTH pregnancy toxemia and hypocalcemia simultaneously. Give SQ calcium + oral propylene glycol. If rapid improvement after calcium = likely hypocalcemia. If slow/no improvement = likely toxemia (worse prognosis).
Tissue protruding from vulva, often in final 2-3 weeks. Apply prolapse retainer or harness when tissue still retracts. Advanced: clean, lubricate, replace, secure with retainer. Loosen/remove retainer before delivery. Cull the ewe after weaning — recurrence likely.
Large mass with round raised caruncles ("meatballs"). CALL VET IMMEDIATELY.
While waiting:
- Keep tissue moist with clean damp towels
- Encourage lamb to nurse (oxytocin helps)
- Apply granulated sugar to reduce swelling (15-20 min), rinse, lubricate, gently reposition if vet unavailable
- Unlike vaginal prolapse — no genetic component, do not necessarily cull
Hot, swollen, firm, or discolored udder half. Ewe walks stiff, won't let lamb nurse. Abnormal milk.
Action: Separate ewe. Strip affected half 2-3x daily. Systemic antibiotics (vet). Anti-inflammatory. Supplement lambs immediately — their milk supply is compromised.
Selenium/vitamin E deficiency → stiff lambs, hunched posture, can't stand. Cardiac form: difficult breathing, sudden death.
Prevention: Adequate selenium in ewe diet during gestation. In deficient areas: mineral mix + vitamin E supplementation. BO-SE injection for lambs at birth (1 mL per 40 lbs) if area is deficient. NOT for pregnant ewes.
Grafting techniques (by success rate):
- Wet grafting — rub birth fluids from foster ewe's lamb onto orphan (best within 1 hour of foster ewe lambing)
- Skin grafting — skin dead lamb, tie hide over orphan for 2-3 days (~90% success)
- Stockinette method — orthopedic stockinette on natural lamb 24 hrs, turn inside-out onto orphan
- Stanchion method — restrain ewe, allow orphan to nurse 3-4x daily for 3-5 days
Bottle feeding protocol: Lamb-specific milk replacer only (not calf). 15-20% body weight per day, minimum 3 feedings. Clean bottles after EVERY feeding. Never reheat leftover formula. Introduce creep feed by 1-2 weeks.
Joint ill: Bacterial infection via navel cord, affects lambs 1-4 weeks. Sudden lameness, warm/swollen joints. Prevention: thorough navel dipping + adequate colostrum.
Watery mouth: E. coli in lambs 12-72 hours old with insufficient colostrum. Wet muzzle, drooling, distended belly, refusal to nurse. Prevention: clean environment + adequate colostrum in first 6 hours.
| Advantage | Detail |
|---|---|
| Strong maternal instincts | Among the best of any breed. Rejection rare. Even yearlings display good mothering. Aggressively defend newborns. |
| Easy lambers | Rarely need assistance (~5% dystocia). Exercise on pasture reduces problems further. |
| Clean udders | No wool around teats = lambs find teats faster = faster colostrum intake. No crutching needed. |
| Vigorous lambs | Born alert, stand and nurse quickly. Hair birth coat aids survival in cold/wet. |
| No docking | KHSI breed standards stipulate undocked tails for breeding stock. Less labor, less infection risk. |
| Parasite resistance | Documented resistance to Haemonchus contortus. Even during periparturient rise, resistant ewes shed fewer eggs. |
| Easy keepers | Need less feed than wool breeds. But don't overfeed — obesity causes more problems than underconditioning. |
| EBV | What it measures | Selection target |
|---|---|---|
| MWWT (Maternal Weaning Weight) | Milk production + mothering ability | Above 50th percentile for replacements |
| NLB/NLW (Lambs Born/Weaned) | Fertility, prolificacy, maternal fitness | NLW is the best single predictor of maternal profitability |
| FEC (Fecal Egg Count) | Parasite resistance | Negative values = better resistance |
Katahdins are well-suited to pasture lambing when predator pressure is managed. Benefits: less dystocia (daily exercise), less mis-mothering (ewes distance from flock), better disease prevention.
Recommended hybrid approach for mid-April: Close-in paddock with shelter access (three-sided shed or run-in). Bring inside only when rain + wind + cold combine (wet and windy below 40°F). On calm, dry nights even in the 30s, healthy Katahdins with lambs over 24 hours old generally do fine outdoors with windbreak access.
- FAMACHA scoring — treat scores 4-5 only (targeted selective treatment)
- Periparturient egg rise begins ~2 weeks pre-lambing, persists up to 8 weeks post-birth
- Even resistant Katahdins experience some rise
- No blanket deworming — preserves refugia, slows resistance development
- Maintain pasture height above 5 inches to reduce larval ingestion
- Uterine prolapse — true emergency, can be fatal within hours
- Dystocia unresolved after 30 minutes of your intervention
- Suspected ringwomb not responding to manual dilation
- Severe pregnancy toxemia — recumbent, unresponsive to oral treatment
- Severe milk fever — unresponsive to 2 calcium treatments
- Signs of sepsis (high fever, rapid decline, shock)
- Suspected ruptured uterus (ewe suddenly stops straining, quiet/depressed)
- Mild-moderate pregnancy toxemia responding to propylene glycol
- Hypocalcemia responding to calcium
- Vaginal prolapse with successful retention
- Mild dystocia resolved with repositioning
- Retained placenta in otherwise healthy ewe
- Mastitis caught early
- Newborn hypothermia
- Identify nearest large-animal vet with emergency availability
- Know C-section cost range ($300-800+)
- Find experienced shepherd mentor locally (phone or in-person help)
- Establish a relationship with your vet BEFORE lambing — don't make your first call an emergency
During active lambing, check ewes every 4-6 hours minimum.
| Time | Action |
|---|---|
| 10-11 PM | Last check before bed |
| 2-3 AM | Middle-of-night check |
| 5-6 AM | Early morning |
| Daytime | Regular checks |
What to look for: Ewes separated from flock, vulva discharge, tight/shiny udder, pawing/circling, water bag visible, active straining. Separate "already lambed" from "still to lamb" groups to make checks faster.
For Katahdins: less intervention is better. If she's not in trouble, don't disturb her.
