Somehow i seriously doubt thats true.
http://sangha.net/messengers/zoroaster.htm Zoroaster forbade all sacrifices in honour of Ahriman or of his adherents, the daevas, who from pre-Zoroastrian times had degenerated into hostile deities. In the prevailing religious tradition, Zoroaster probably found that the practice of sacrificing cattle, combined with the consumption of intoxicating drinks (haoma), led to orgiastic excess. In his reform, Zoroaster did not, as some scholars would have it, abolish all animal sacrifice but simply the orgiastic and intoxicating rites that accompanied it. The haoma sacrifice, too, was to be thought of as a symbolic offering; it may have consisted of unfermented drink or an intoxicating beverage or plant. Zoroaster retained the ancient cult of fire. This cult and its various rites were later extended and given a definite order by the priestly class of the Magi. Its centre, the eternal flame in the Temple of Fire, was constantly linked with the priestly service and with the haoma sacrifice.
