Photosensitisation i Sheep
Photosensitisation in Sheep? – FABSTOCK can help
Kyle Sturgess, pictured, from Redline Stud @ West Wyalong contacted FABSTOCK in August '24. Kyle, who also works as a contract stock agent, had a client at Lake Cargelligo, who had ewes & lambs grazing lucerne and the lambs had developed severe facial eczema.
The condition was caused due to cowpea aphid, which had infested the lucerne. The lambs were ingesting aphids as they were grazing, and it is believed that the aphids contain a pigment that causes severe photosensitisation.
The condition was first reported on the Monaro in 2021, and it caused significant losses of lambs and longer-term impacts for those that survived 1
When Kyle contacted FABSTOCK, the lambs were struggling badly as the photos show.
We suggested Fabstock LSM ‘Summer Weeds Plus’. Whilst designed initially for sheep grazing cereal stubbles where weeds such as Hairy Panic and Heliotrope were a problem, we were able to make the necessary alterations to improve suitability for protein rich pastures such as lucerne.
Talking on Tuesday, Kyle commented:
“Whole mob, consisting of between 4 – 600 lambs where badly affected.
And they were bad. They were as bad as you think sheep could be and still be alive. 8 weeks after starting on the product (Fabstock’s LSM ‘Summers Weeds Plus’), you couldn’t even tell there’d been a problem. 8 weeks from absolutely buggered to perfect. The hair had grown back and there was no sign of scaring.
I would happily say that those lambs were unmarketable, unsaleable un-anything. 8 weeks later, they could have gone straight into the marketplace and been sold, no problems.
I told the client that she was going to lose a lot, at least 10% or more. Ended up losing bugger all!”
As always, prevention is better that cure. Don’t let photosensitisation ruin your valuable livestock and more importantly, your profits.
