Housed lambing systems concentrate welfare risks from exposure, mismothering, and infectious disease, requiring intensive management to ensure individual ewe and lamb welfare across the lambing period.
Housed lambing represents a welfare management intensive period that requires continuous observation, prompt intervention, and careful environmental management. The neonatal lamb is highly vulnerable in the first hours of life: it must stand, find the teat, and consume adequate colostrum before its own thermoregulatory capacity develops. Failure at any point — difficult birth leaving the lamb weak, a ewe with insufficient milk, competition from a twin sibling, or environmental cold — creates a cascade toward hypothermia and death. Good welfare outcomes require shepherds to assess each lamb at birth using the LAMB system (Lively, Active, Mucus cleared, Born in a clean area) and intervene promptly with supplemental feeding, warmth, or fostering where indicated. Housing density management during lambing maintains the ability to observe individual animals without the pathogen concentration that causes neonatal infections. Mismothering management — isolating ewe-lamb pairs in pens for 24-48 hours — allows bonding to establish before returning to the group.
