Plural of Ox
For ordinary modern use, more than one ox is usually “oxen.” Current Merriam-Webster treatment also records “ox” as a plural variant, so it is too absolute to say that “oxen” is the only dictionary-recorded plural. Use “oxen” as the clear default unless a source or established context supports invariant “ox.”
The usual plural of “ox” is “oxen.” Merriam-Webster also records invariant plural “ox.”
