Tyddyn Cae Project Update - November 2024

Target Outcomes for the Project:

• Increase the proportion of heifers calving within the first four weeks.
• Implement effective heat detection strategies to improve submission and conception rates.
• Ensure optimal herd health through a thorough review of vaccination and disease management protocols.

Action Plan/Next steps:

Changes to Mating Plan for Heifers:

• Heifers to be divided into three groups based on bulling timing:
• Group A: Bulling in the 7 days leading up to PSM; these will be separated and grouped together. Expected: ~33% of heifers bulling week -1, due to bull in week 3.
• Group B: Bulling in the first week. Expected: ~33% of heifers.
• Group C: Bulling in the second week. Expected: ~33% of heifers.
• On day 6 of mating, Group A are to be injected with prostaglandin to bring forward the next heat - this should be expected 2-5 days after injection. Mate only to observed heat. 

Goal: Mate all heifers within a two-week period instead of the usual three weeks.
