Dear Mohair Producer
To keep you updated on the prevalent diseases investigated on Post mortem and farm visits over the last two weeks of September.
- Heartwater deaths in Baviaans area
- ‘Rooiderm’ in 5 weeks old kids in excellent condition on lucerne lands, cultured as Clostridium perfringens (likely Type A but awaiting Onderstepoort results)
- Isolated Clostridial related deaths in kid in excellent condition after creep feed introduction- still to be confirmed by pathology (suspected Clostridium perfringens type D).
- Abnormal numbers of kids (>10% of kids) dying at between 7 and 13 days after birth -awaiting sample analysis.
Roundworm counts have been relatively low due to dry veld conditions but even on lands the faecal egg counts have in most cases been low due to the cool temperatures.
- HEARTWATER
Heartwater outbreak on Angora farm in Baviaans (non- endemic area) was diagnosed on Post Mortem on 3 adult angoras and exam of a sick goat. The sick goat had a fever of 41.7C
Post Mortems revealed classical Heartwater lesions
- Fluid in chest cavity and heart sac
- Haemorrhages on outer and inner surface of heart muscle (marked with red arrows in photo below)
