Twin Lamb Management for Welfare
Twins represent the most common lambing outcome in many breeds and are associated with higher lamb mortality and welfare challenges than singles. The second twin is often smaller, born later, and at greater risk of hypothermia and mismothering. Proactive management of twin lambings significantly improves welfare outcomes.
Twin Birth Challenges
Second twins often arrive with less vigorous maternal attention — the ewe has already begun bonding with the first lamb. Second-born twins are frequently smaller, have had a longer birth canal experience, and arrive in a declining temperature gradient after the placenta has partially expelled. These factors combine to increase hypothermia and mismothering risk for second-born twins specifically.
Triplets and quads further amplify these challenges — lambs may be too small to sustain themselves without intensive intervention, and the ewe typically cannot adequately nurse more than two lambs. Fostering third and fourth lambs onto ewes that have lost their own lambs, or artificially rearing, is necessary for their welfare.
Colostrum Management for Twins
Both twins must receive adequate colostrum in the critical first hours. Ewes with twins often have adequate colostrum supply, but competition between siblings can result in the smaller, weaker twin not nursing adequately. Observing twin lambs nursing — confirming both are latching and swallowing — and supplementing the smaller twin if needed prevents failure of passive transfer.
Stomach tube supplementation of weak or slow-to-nurse twins using ewe colostrum (or banked/commercial colostrum replacer as backup) in the first 2-4 hours is one of the most impactful welfare interventions available at lambing.
Mismothering Prevention
Quiet, calm lambing environments with individual pens for ewes and their lambs in the first 24-48 hours significantly reduce mismothering. The bonding period — when the ewe imprints on her lambs' scent and vocalisation — must occur without interference from other ewes or lambs. Adequate pen space (minimum 1.4 m² per ewe-and-lambs unit) reduces disturbance between families.
If mismothering occurs (ewe butting away a lamb), fostering techniques using natural (lamb adoption pen, ewe restraint for nursing) or chemical (applying fostering aids, amniotic fluid) methods can re-establish acceptance.
Monitoring Twin Welfare
Regularly weighing lambs in the first week identifies poor doers before welfare is severely compromised. Twins below 10% of their birth weight gain target by day 3 warrant investigation and supplementation. Body condition (bright, alert, well-filled abdomen vs. hunched, dull, tucked abdomen) provides rapid field assessment.
