It is narrated from Umm al-Mu'minin Aisha Siddiqa (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him) sent goats for sacrifice. And in another narration, it is stated that he (peace and blessings be upon him) would send the goats after putting collars on them, while he himself remained in his house in a state of being non-muhrim (not in the state of ihram).
