How cows digest food

We have milk everyday but how is it made? Firstly cows eat 70kg of grass each day.
Then it goes through a cows first 2 stomachs and turned into cud .
Next they burp it up and chew again for 1 minute. After that it is crushed into lettle pieces and is absorbed into its bloodstream.
Finally it goes into the udders and the cow is milked.The milk goes to a factory where it is bottled and collected by milk trucks and sent to sops where people by it.
Now you know how grass is turned into milk.
