We are creating a new turnout and it is directly under an olive tree. Every year it drops thousands of olives. We are putting up a fence so the horses can't eat the bark, but what about the olives? I know that people can't eat olives raw they need to be pickled. Can horses? I believe olives contain arsenic - though I'm not sure. The pits are also very sharp. I was going to put a net up to catch the vast majority of the olives as they fall. Will this be safe? |

Welcome Martha,
I cannot find any evidence that olives are toxic however they are considered inedible until they are processed. This usually takes the form of fermentation, brine, alkali, or some combination of the three. But this is to remove the very bitter phenolic compounds and glycosides and I do not find any cases of poisoning nor reports of specific toxicity. Maybe they are toxic but so bitter no one is ever poisoned?
But the bottom line is I really do not know how safe a olive tree might be in the pasture. Besides specific toxicity there is the concern of dietary change it represents during the fruiting season and as you mention the possibility the pits may cause trouble. If olive trees are common in your area your local extension office should have some further information for you.

As I live in Greece, olive trees are all around, at home, at the stables, overhanging some paddocks, everywhere.
We've never had a problem, even though the horses eat a mouthful of the leaves once in a while and the leaves naturally fall into the water buckets now and then. I've never seen a horse choose to eat the actual olive fruit, although we don't have pasture - I suppose while grazing a horse could accidentally ingest olives along with the grass. However, horses are pretty good at separating out what they don't want to swallow.
So .. I know the leaves aren't poisonous to horses, I know that our horses do not eat the fruit and I've never heard of anyone else's horses eating the fruit - but I can't guarantee that yours will not. I agree that you wouldn't want them to swallow the pits in case they caused a blockage.
Olives are certainly not toxic to people(!), nor to dogs (mine gorge on them in autumn when they fall, even crunching up those rock-hard pits somehow - it always worried me but I couldn't keep them in all day).
IMHO it will be fine, but you might want to observe your horses just in case they find the olives to be a delicacy, and put up a net if so. |
