I just wanted to say,bread will kill a cow. Someone fed my two beef cattle a large amount of bread,which they could not digest.Will bread kill any other animal?

The University of Cornell did a study showing that bread can be fed to cattle, stating that bread is more digestible than corn, because bread is already processed.
See the study results: Studies show bread in diet is good for cattle

"The Backwoods Home Magazine" states, in an article, that feeding bread is safe, if done in small amounts in the beginning, to avoid bloating and diarrhea.

Bread can also be fed, in conjunction with other items, as a drought feeding strategy. See the article from a Cooperative Extension Service in S.C. -
