[Terrapreta] charcoal and livestock

[Gerald Van Koeverden]

Chris,

Can't answer your question.

However to add to the previous article on large livestock and  
charcoal, here's the abstract of a recent research article on adding  
charcoal to chicken feed.  It was found to significantly increase  
feed conversion ratios in broilers.

Whether or not biochar could be used in this application, might well  
depend on its VOM.  Too much might prove toxic?  But a high quality  
char could well be beneficial to livestock feeding.
