The ‘NABS Reproductive Disease Investigation Guidelines For Veterinarians’ describes the:
- Level of repro performance seen in different regions of northern Australia
- Risk factors – from nutritional conditions and management practices, to infectious diseases
- Diagnostic information for infectious disease agents.
The corresponding producer publication includes:
- Questions they may be asked in an investigation
- How herd records can help diagnosis of the problem
- A body condition score tool
- Indicative costs of laboratory tests.
Investigations of poor reproductive performance in cattle are complex. Using the NABS Disease Mapping framework can help it into systematic, doable steps. Start by:
- Working out who’s affected (eg heifers, first lactation vs mature cows)
- In what way (typical case description)
- Putting together a timeline with notable events (Temperature Humidity Index at calving, pasture quality and availability, mustering and management etc)
- Taking (10+) bloods from affected and unaffected mobs can be a good start.
