Dear Mohair Producer

To keep you as a Mohair producer up to date with disease monitoring within the industry some feedback from Post Mortems and problems reported over the first two weeks of October.

Due to dry conditions no significant disease outbreaks have been reported or diagnosed these last 2 weeks; however poor mothering has resulted in many kid deaths.

The roundworm population remains low at present due to the dry conditions  and even on pastures the egg counts remain lower than previous years due to the lower than expected temperatures.  The coccidia counts have however been surprisingly high.  Be aware there may be a spike in roundworm counts about 3-5 weeks after the first rains (hopefully soon) due to the current lowered immune status of the goats (nutrition) and life cycle of the roundworm.

Of the unusual findings:

  • There have been high coccidia counts on a number of farms. Coccidiosis in mature goats are very seldom a problem but there have been a couple of PM’s on adult goats where coccidiosis has had a significant influence on death. Again nutritional conditions may have resulted in a lowered immune status and more favourable transmission conditions in high-density areas around feed troughs may have played a role.

This does mean we will need to monitor our kids closely for clinical signs of coccidiosis over the next few months (most commonly seen in kids below 4 months old). If concerned get a faecal sample checked.

Of interest in the Post Mortem below the Yellow arrow shows the lung oedema and the orange arrow the fluid in the chest cavity.

The hypoproteinaemia due to coccidiosis led to formation of oedema of lungs and death of this angora. 

  • Abscess formation both as an incidental findings on post mortem and pathogenic causes of death may also be higher due to stressed conditions. Of interest which demonstrates that pneumonia must not always be blamed on pateurella.

 In this case the severe pneumonia was caused by Corynebacterium ovis (diagnoses on culture). See the abscess formation in the spleen (orange arrow) and severe pneumonia of lungs (yellow arrow) as demonstrated in the lungs below.

Also lymph nodes draining the lung abscessed (held by hand in photo on the left).
