Strategy for managing lambing
There are three strategies commonly used in Australia. Each has its benefits but the appropriate strategy should be decided upon for each property.
Leave lambing ewes alone.
This is a traditional approach in some areas. Ewes in trouble were left to die, which was a form of genetic selection. This also prevented losses due to ewes leaving their lambs to approach the vehicle, and leaving the lamb behind. Poor animal welfare may be a consequence of this approach if ewes are not prepared properly for lambing.
Checking lambs daily.
This is best done in the afternoon, when ewes are settled, or twice daily on small properties. Sheep should be made accustomed to people in the lambing paddock beforehand, so they don’t approach the vehicle expecting food. Ewes in trouble can be given assistance, and tagged to indicate their history. This approach is more suited to smaller lambing paddocks and high stocking rates. It can also ensure better levels of animal welfare and ewe and lamb survival. Caution is required if ewes are not accustomed to a vehicle or people entering the paddock as they may rush the vehicle expecting feed or run away frightened. Both will result in mismotherment.
Surveillance.
Observe sheep behaviour from a distance but do not disturb unless necessary. Lambing ewes being moved from one paddock to another should be left to move slowly through an opened gate over several hours. Technology such as fixed cameras or drones can be used to improve the efficiency of this strategy.
