nah ah ah
In English, the Navajo word ná’á’ah is a general term for a butchering. Navajo people frequently butcher sheep and cattle, and sometimes other animals like deer, and elk. Butchering happens both for special occasions and for subsistence.
If you wanted to say something to the effect of “Today there will be a butchering,” then na’a’ah is an appropriate word. The word will change a little bit when speaking of butchering specific animals, but depending on the availability of livestock the specific animal can also be implied.
