Alert - Atypical Myopathy

The toxin responsible for atypical myopathy is also contained in sycamore seedling (Acer pseudoplatanus maple tree). Currently, there are large number of sycamore seedlings coming through.

So, it is imperative to avoid that equidae (horses, donkeys, zebras…) ingest them. It is important to browse your grass to make sure it does not contain these seedlings.

The spring outbreak has started and the number of cases of atypical myopathy increases in recent days.

As far as possible:
- temporarily limit access to pastures containing sycamore maple seedlings (or delimit grazing to avoid areas where seedlings are present in large numbers);
- limit pasture time to a few hours a day (the majority of cases grazed > 6h / day);
- whenever possible, feed the animals before putting them in the meadow;
- organize the rotation of pastures to offer exclusively lush grasslands;
- do not place food (hay or other) on the ground;
- try to destroy the seedlings as early as possible by mowing, harrowing (cutting/ break the cotyledons of the seedlings should kill them) and/ or burn them. For reasons of environmental protection, avoid chemicals. Be careful, do not offer these pastures right away as it has been shown that even faded seedlings still contain the toxin ( Wait until the seedlings have disappeared and the grass have grown;
- consider cutting branches of maple trees near pastures to avoid the production of flowers and seeds.
