[Vampire Fiction] In stories where the Holy Cross only repels vampires because of the belief in the symbol, could a Hindu Vampire Hunter use trained bulls to hunt vampires with?

Bulls and Cows are sacred in several cultures so if they belong to a person that holds them as such they should be as effective as a Cross is for a Christian.

In most fantasy world settings, since there are usually dozens of religions, vampires are rebuked by Good aligned Holy symbols (some have to be lawful good, and the real fun begins when an evil cleric uses his symbols to CONTROL the undead).

But as stated elsewhere, Bulls are considered sacred, not a holy symbol themselves.
