Isn't it bad luck to cut down a yew?

 

On the lethality of yew, I know farmers who are terrified of it.. They are convinced that the smallest leave/needle will wipe out their cows and sheep.. and have seen it happen...! I'm not convinced...

 

I've been meaning to look it up for ages, found this:

YEW

 

Contains an alkaloid, taxine, and a heteroside, taxicatoside. Toxicity is maximal in winter and is not reduced by drying. Cut branches that are a few weeks old are more toxic than when fresh.

 

Oral doses in g fresh plant material per kg/ body weight:

LD cattle 1-10

horses 0.5-2

pigs 3

sheep, goats 10-12

dogs 8

rabbits 20

 

So if an cow weighs 400kg it would need 0.4 - 4kgs to kill it! Whereas a horse the same size only 0.2kgs.. I guess it's not a lot for a hungry animal to eat!

 

 

Thats REALLY interesting, I had a theory that the cut stuff was worse than live.

 

I have seen fenced of Yew's that are clearly being grazed, presumably the tree does not produce enough growth within reach fast enough to prove fatal.

 

But I know of 2 cows killed (autopsy's was performed to prove cause of death) by Yew hedge clippings thrown into the field by the home owner.
