Study Notes

Indoor Lambing

  • Protects sheep and shepherd from bad weather
  • Reduces risk of lambs dying from hypothermia
  • Allows for closer supervision of lambing
  • Enables early lambing to take place
  • Helps preserve pasture growth and recovery
  • Requires higher labour input
  • Increases risk of infectious diseases
  • Requires provision of feed, bedding, and water

Outdoor Lambing

  • Requires less labour input
  • Has lower capital expenditure and fixed costs
  • Reduces risk of infectious diseases
  • Is limited to lambing flocks that can start later
  • Requires sufficient pasture to be available
  • Increases risk of lambs dying from hypothermia and starvation
  • Increases losses due to dystocia
