Study Notes
Preventing Flystrike with Genetics
- Breeding for resistance to breech strike provides a sustainable, long-term solution to flystrike issues in sheep.
- Selecting superior rams and ewes with measurable and heritable traits is essential for effective breeding practices.
- Certain traits associated with breech strike can be identified and used in breeding programs; these are termed "indicator traits."
- Key indicator traits related to breech strike in winter rainfall environments include:
- Low wrinkle
- Low dags
- Adequate breech cover
- The presence of multiple indicator traits on a single animal enhances resistance to flystrike due to their interactive effects.
- Genetic selection strategies can be employed across different sheep categories:
- Lamb flock selection
- Existing ewe flock assessment
- Choosing rams from sources focused on genetic resistance to flystrike.
