Zisuili

From Turtledove

Zisuili is a large stock animal native to Home and used by the Race as a foodstuff. Zisuili are also edible to humans. The Colonization Fleet brought zisuili and several other species of livestock to Tosev 3. As Earth plants were not equipped to deal with the extremely economic grazing patterns of these animals, some ecological damage resulted. This in turn led to diplomatic tensions between the Race the various human powers.
