stresses and diseases compared with older sheep. Lambs are born
without antibodies to protect them against disease and only after they
have received a good supply of antibody rich colostrum will they have
any protection against infection. Even after the early lamb stage, lambs
are very vulnerable to many diseases including gut and skin parasites.
Most lamb losses occur around lambing time. The major causes of lamb death are:
- Abortion and Stillbirths
- Exposure and Starvation
- Infectious Diseases
- Congenital Defects
- Predators and Misadventure
Many lambs could survive with better planning, good preparation, well
organised lambing routines and facilities, good stockmanship, possibly
increased supervision and staffing numbers around lambing time and
early recognition of problem lambs.
Improving lamb survival follow:
- Higyene
Disease spread within and between flocks can be reduced by the application of simple, common sense
quarantine rules as part of a farm biosecurity
- Health program
Including disease investigation and vaccination program
- Exposure and starvation
Attention to ewe condition, feeding and management plus early recognition and
correct treatment of lambs at risk
- Misadventure and Predators
Turning out weakly lambs and mis-mothering can lead to high losses
