What is valid for a specifically named sacrificial animal vowed by the person?

Primary text

If the Hady is specified by utterance or intention, whatever is named suffices, regardless of its size or value, as it is still termed a Hady. The Prophet (peace be upon him) stated, "Whoever goes at the fifth hour, it is as if he gifted an egg." The reason for reverting the unspecified vow to the established legal standard is that the name has become dominant, similar to vowing to pray, which necessitates a legally prescribed prayer, not merely linguistic prayer.
