Step 1: Cows

Cows produce milk from the four different process of its stomach. 1 The rumen, which the cow will chew the grass half way. The rumen softens and breaks down with the stomach juices and microbes or bacteria. Then theres the reticulum, which makes the grass even softer, it will come back up for the cow to chew for about a minute. Theres also the omasum, which is digested in to the stomach were the cud of grass is broken down even further. The last step is the abomasum were the grass is digested. Some of it goes to the udder and the other is used for the cow to stay healthy.
