Sheep Lambing Season Welfare: Neonatal Challenges and Farmer Responsibilities

Lambing is one of the most intensive periods of sheep farming, with welfare challenges for both ewes and newborn lambs. Good management practices at lambing significantly reduce mortality and suffering.

Key Facts

Sheep can be induced to lamb at different times of year through light manipulation, breed selection, and hormonal treatment; outdoor lambing in spring and indoor winter lambing each carry different welfare profiles
Neonatal lamb mortality is one of the most significant welfare problems in sheep farming, with UK surveys suggesting 15–20% of lambs die in their first month of life, largely in the first few days
Hypothermia is the leading cause of neonatal lamb death, typically occurring when lambs are born wet in cold or windy conditions without adequate shelter or maternal attention
Dystocia (difficult birth) requiring assistance causes pain and exhaustion in ewes; malpresented lambs may suffer oxygen deprivation during prolonged labour
Ewes carrying triplets are at elevated risk of pregnancy toxaemia in the final weeks before lambing — a metabolic disease causing progressive weakness, recumbency, and death if not treated promptly
Mismothering — failure of the ewe to bond with her lambs — is more common in high-stress lambing environments, indoor housing with limited space, and in primiparous (first-time) ewes
Good shepherding during lambing — checking flocks frequently, especially at night, and intervening early with orphan lambs — is the single most effective welfare intervention available

Welfare Considerations

Lambing season concentrates welfare challenges for both ewes and neonates into a short, intensive period. Ewes facing difficult births experience pain and exhaustion that, if veterinary assistance is unavailable or delayed, can be prolonged and severe. Newborn lambs are highly vulnerable: they must suckle colostrum within the first 6 hours of life to acquire passive immunity, must dry off rapidly to avoid hypothermia, and must successfully bond with their mother to receive ongoing nutrition. Each failure point — a cold wet night, a ewe that rejects her lamb, colostrum unavailability — can cause suffering and death within hours. High-stocking-density indoor lambing can impair maternal bonding by preventing ewes from separating adequately from the flock to focus on their lambs, while inadequate individual pen provision means that ewes giving birth may do so in high-traffic areas where bonding is disrupted. Improving lambing welfare requires investment in stock-person training, adequate shelter, individual bonding pens, colostrum banking, and lambing monitoring technology.

What You Can Do

Support farming subsidies and training programmes that help sheep farmers implement better lambing facilities and stockperson welfare training
Choose lamb and wool products from farms with certified welfare standards that include lambing management requirements
Advocate for adequate veterinary access for sheep farmers during lambing season — rural vet shortages directly compromise welfare outcomes
Support research into early warning systems for dystocia and pregnancy toxaemia that can alert farmers before conditions become severe
If you see abandoned or distressed lambs in accessible agricultural settings, contact the farmer or local animal welfare organisations rather than intervening directly
