Co-benefit for altering management to reduce methane emissions is that an increase in the reproductive rate by mating ewe lambs increases on-farm profit.
Opportunities for altering management for reduced methane emissions:
- It is relevant to all sheep enterprises in WA.
- Mating ewe lambs can reduce total carbon emissions by 7.5%.
Risks associated with altering management for reduced methane emissions:
- Reducing the reproductive rate of the flock by varying flock structure reduces profitability by much more than the current value of the carbon emissions saved.
- The reproductive rate achieved from the ewe lambs is likely to vary widely between good and poor seasons.
- If the sheep meat price drops, the incentive to continue mating ewe lambs drops.
