We are new horse owners, and I wanted to check this out since we have been told conflicting information by our various neighbors who own horses. Is it harmful for horses to eat grass that has been freshly mowed or cut? Some neighbors say it causes horses to colic because the freshly cut grass releases a substance that is toxic to horses. Others laughed in disbelief and said they never worry about it and have been doing it for years. They couldn't believe we believed that there could be a problem. The reason I ask is that we have a field that needs to be cut, so we can put up new fencing. I wondered if the horses should not be allowed in that field after it is cut...and whether we should rake it up. If horses are not suppose to eat freshly cut grass or hay, then how long should the horses be off that pasture? I did try to look for this answer among the posts, but couldn't find it. Thanks for any help. Dee |

Dee.. I know what works for us.. my pastures are underwater and marshy for a long time, while drying out the grass becomes thigh high and very lush.. what we find works for us.. is the time put in weed whacking it down, giving each horse a wheel barrel of raked up clippings per day.. when i can open the pastures, they are used to the lush grass and i don't worry much .. all tho, that being said.. they are only allowed on the lush grass the first few weeks on hourly times.. to make sure.. NEVER LAWN MOWER CLIPPINGS.. oils and such from the power mower can leak onto the grass cuttings.. weed whacking is just pulled grass.. On the first day God created horses, on the second day he painted them with spots.. |

I've always heard that if a horse is to eat freshly cut grass, it needs to be fed right after cutting. If it sits even a few hours, it can start fermenting and can cause severe colic. I know of two horses that died from eating clippings. I always keep the horses off a mowed field until the cut grass dries out. |

I wonder if the horses died from something else in the grass? Like Oleander leaves or another highly toxic plant that gets chopped up really small? A few leaves will kill a full grown horse. |

No, it was just grass. These horses lived near my in-laws, and when we drove by one day they had a huge pile of grass clippings their owner had given them. I commented as we drove past that I'd always heard that was dangerous to feed clippings to horses. Later I learned that two of the horses had colicked and died. The owners left the clippings instead of hay for the horses, and left for the night. When they returned, two of the horses were dead. |

hum.. that is interesting.. I sometimes will weed whack the night before .. the next day will rake up and feed.. Also there have been summers where the pastures dried quickly, we were able to use a bush hog to cut the grass down.. left lay, and later in the month turned horses on it.. never had a problem at all. When they cut hay... it sits on the fields to dry before bailing.. On the first day God created horses, on the second day he painted them with spots.. |

If you weed whack tall grass, there shouldn't be a problem. It is the grass cut by a lawn mower that is deadly. The clippings are too short, they can get impacted. EO |

I have had a horse choke from lawn clippings that a neighbor threw into my pasture. He thought he was doing me a service, but it was really scary. It all balled up in the horse's throat . . . she was so happy to have them that she gorged on them . . . so, from my past experience, I never feed freshly cut grass to horses. |

I read in one of the better horse magazines, can't recall which one now as it was quite a few years ago, but they said not to feed grass clippings freshly mowed, it can kill. Something about the chemical of the plant and what happens within the plant. Dried it's okay. Not knowing this I tried giving Sierra some clippings once, and luckily she refused them. That was a horse that would eat anything!! Shirl |

YES!!! cut grass ferments. it dies. and ferments. I don't know how i know that but don't cut the grass and then let the horse eat it. The first couple of hours i'm sure is fine. but anything after that i wouldn't chance it. I'm not sure but the word phytotoxin popped up in my head, when i was writing this not sure if that has anything to do with it either. which is a fungus. I gotta go look that up... |

I've always figured freshly mowed grass was too much like silage to feed to horses so I have never fed the clippings, or let them graze freshly mown pastures. I was told that cattle can handle the silage and even some moldy hay, but horses' digestive system is way too delicate for that, which I agree with. |

Hello Everyone, Most fresh cut grasses are not particularly toxic but let's put all the qualifiers in:- We are talking about the common pasture or lawn grasses. There are some sorgum /sudan grasses that can form cyanides from prussic acid after being cut under some conditions.
- You should remember there are some toxins and toxin-generators (like fructans) in both regular grass and clovers that will not change when cut.
- If it has been put in a pile and begun to ferment it may have formed botulinum toxin.
- If it is tainted with oil and gas that is not so good, but I doubt the horses would eat it.
- And there is no doubt grass mown with a lawn mower will choke a horse in a heart beat. I saw 2 horses that choked simultaneously on lawn mower clippings. I think the finely clipped grass is luscious to them and they attempt to swallow large amounts without chewing well.
So lawn mower clippings should go on to the fermentation pile but a pasture mown with a rotary pasture clipper (bushhog) is probably safe as long as it does not accumulate in big piles that rot. DrO |

When I had a mare and post-op newborn on stall rest for 2 months, I went out each morning and cut in the bahai hay field with the bush-hog. I fed some grass immediately(it was 12-15 inches long), and bagged the rest in Wal-Mart sacks and put them in the fridge. They smelled fine for up to three days. I fed that way for 2 months without ill affect, except the marital strain from the dead grasshoppers in the fridge!! |

I, too, had a horse choke on fresh grass clippings--never again! But I do let them graze mown pastures with no problems. I guess it needs to be spread out to dry properly. |

This is a great "problem" to have, unless you have overweight or laminitis prone horses. Lilo |

Dr O, Is the newly cut lawn mower grass dangerous (such as a release of toxins) because of the metal blade? after discarding the clippings. |

No the metal introduced by the blade is not toxic. DrO |

I cut and feed my guys fresh grown wild alfalfa and toss it in the arena at nite as a treat - cut and toss with in 10 minutes - eaten by the boys in less then 15 minutes - I can see them smack their lips in appreciation. I do this cause they look at it all day from the confines of their paddock off the barn that is all dirt. it also helps me keep the yard looking better as we don't mow the wild flowers. |
