In answer to the letter “The real danger of the ‘yellow peril’ to horses” (11 June 2019), I well know the damage ragwort can do, particularly when concealed in hay.
I had a horse that died as a result of eating ragwort. I bought a mare and foal from the Thetford area (light, sandy land and particularly liked by ragwort) and within three weeks the mare died.
I thought her poor condition when I bought her was due only to foaling, but it turned out that she had been so hungry, living and feeding her young foal on poor grass, that she had been eating ragwort as it grew with the grass in the field.
I know this is unusual. When I returned to look at the field after only a few weeks the ragwort was high and obvious, which was certainly not the case when I bought the mare.
With regard to being concealed in hay, avoiding this danger depends on careful husbandry on the part of haymaker and horseman.
Good hay is a rare thing. I think Shakespeare put these words into the mouth of one of his characters: “good hath no fellow”. Historically, good hay would have been of huge importance to anyone keeping stock before the advent of haylage, silage and the many alternative, storable feeds we now have available.
The way I coped with this potential problem was to feed good barley straw and hydroponically grown barley “grass”, instead of hay.
I too have tutted over the sight of fields of ragwort, but I now believe that looking at the bigger picture, we humans have to be a bit cleverer about our stockmanship than to just say “exterminate the ragwort”.
