Aim: Achieve a suitable body condition of sheep at mating to increase the fertility rate.
- What is implemented;
The BCS of every sheep must be assessed before the start of the mating season; BCS should be ≥2.5 and/or gaining weight at mating. Therefore, sheep with BCS below 2.5 should receive supplementary feeding before matings (flushing).
- How is implemented;
Sheep below 2.5 will be supplemented with 250-400 g. of concentrate daily (cereal grain); for the rest of the sheep, keep balanced feeding and avoid changes after the critical time of implantation of the embryos is over.
- When is it implemented.
At least 1 month before the expected mating period, and after the critical time of implantation of the embryos is over (19 days after the mating, approximately)
10-20% higher fertility rates and prolificacy, and a more concentrated lambing season
Prerequisites and/or limits (knowledge, training, capabilities, cost, management, facilities, equipment, etc.)
- Education and regular practice or training of farmers regarding BCS assessment;
- Sheep need to be managed individually to be assessed;
- Additional feeding costs for purchased concentrates or on-farm high quality feedstuff resources available (pastures, crops, etc.).
