The haylage I have has this funny white powdery stuff, especially on the edges of each bale. (I buy the small bales). It doesn't smell like mould, the bales are all well sealed with no holes and are only open for 2 days before they are finished. Does anyone know what this white powdery stuff is, and is it harmful?
i got told off the farmer it was a yeast like stuff. He reconed it was harmless to eat but if the haylage was left to dry out the "powder" went more dusty and you wouldnt want the horse breathing it in. My hotrse has never objected to eating it.
White powdery stuff almost like cream is ok I think, it's when the haylage is black that it's gone off and needs to be thrown away. If in doubt smell it, if it smells sweet it's alright, if it's a vinegary smell (very nasty smell) throw it away.
