Why animal sacrifice in santeria?

Animal sacrifice as a religious practice, not as something done to produce food, is definitely Non-Christian. There is no mention, except possibly historical of animal sacrifices, sometimes called Burnt Offerings, in the New Testament. It was common in the old. often animals such as birds and goats are ceremoniously dispatched on stage to unusual rites. This is not Christian. It is also cruelty to animals and occasionally makes the headlines when animal carcasses or remains are found dumped on city sidewalks- such as a decapitated Turkey on Kennedy Boulevard, and feathery remains of a big chicken, etc. it is sickening.
