In Hindu religion : Cow is a carrier of Siva ( one of three gods in Hindu).
In buddhist (Theravada) thai style, It's depend on their believes , mixed up to culture and influenced by Mahayana and Hindu ?
It is big animal ( it meant it has more good karma than other small animals(short life cycle) and also work as in the farm, rice field - Rice is the main dish.
We drink milk to survive when we were young.
Somebody used to see " the method to slaugter it" and could see it's very stress and crying.
Do you know about Kyun-yin ? a goddess of Mercy( Mahayana Buddhism), she didn't eat beef because her dad (who was a bad king) reborn to be cow for 500 yrs.
Why beef and not pork ? in Real Buddism. It's sin to kill animals ( If you kill by yourself, order someone to do that, or pleasure when someone kill for you)
also I'm not in 95 % who went to the temple to pray for won a lotto. It's midlead by culture and their believes! It's not taught in Buddhism
