It depends on the species of plant to determine how much is toxic. For some plants such as oleander, as little as a few mouthfuls of the right part of the plant can kill a horse in minutes. The yew is another extremely toxic plant, with as little as 8 ounces capable of killing an adult horse in 5 minutes!
Then there are the plants like bracken fern that slowly cause problems and a negative reaction might not occur until months after the plant has been eaten.
It also depends on the growing conditions of the plant...in some growth conditions a plant may be barely toxic, but put it in another growing condition and it could be extremely toxic.
To compound the problem, some plants don't even have to be eaten to be toxic! Black walnut is one example...using shavings from this tree in your stalls will cause laminitis in your horses when a mere 10% of the shavings are black walnut!
