Ya Errithil is a Part of Hindu Culture so that every house can Serve the Mother... after that it became a part of Malayalee Culture ... Even many Christian Families Adopted it ... while other Christian Converts still followed the long tradition to keep a House hold cow although not for religious purpose...
Until my Grand Father was alive he never left the House in morning unless Cow is tied at the house entrance ... he first fed the Cow with Grass then took her blessings, after only went outside the house ...
i'll tell u again ... not even most Christians Kill Cow in Kerala... the most Beef are from Buffalo in Malayalam pothe erachi ... & some from Kaala ( Bull)...
but if some Hotel is caught serving Cow beef in Pandalam it would be a serious issue... most hotel sell it in the name of Buffalo Beef...
