Mainly in the small intestine, but nutrient absorption also occurs in the rumen and omasum.
Eighty percent of nutrient absorption occurs in the small intestine. The other 20% occurs in the stomach tissues.

The microorganisms in a cow's digestive system, particularly in the rumen, are collectively referred to as the rumen microbiome. This community includes bacteria, archaea, fungi, and protozoa that help break down fibrous plant material, facilitating digestion and nutrient absorption. The balance and diversity of these microorganisms are crucial for the cow's health and productivity.

Cows digest food through a unique process involving a specialized stomach with four compartments: the rumen, reticulum, omasum, and abomasum. They initially chew their food briefly and then swallow it, allowing it to ferment in the rumen, where microbes break down complex plant materials. Afterward, the partially digested food is regurgitated as cud, chewed again, and swallowed for further digestion. The food then passes through the remaining stomach compartments for nutrient absorption before moving to the intestines for further processing.
By the circulatory system, using the heart as a means to pump blood through out the body.
Goat milk and cow colostrum form a dynamic duo for baby probiotics, supporting digestive health and immunity in a natural way. Goat milk is gentle on sensitive tummies, rich in nutrients, and packed with prebiotics, which nourish good gut bacteria. Cow colostrum, the nutrient-dense first milk, boosts immunity and enhances the gut lining with its high levels of immunoglobulins and growth factors. Together, they create a potent combination to foster healthy digestion, improve nutrient absorption, and strengthen the immune system—ideal for babies and toddlers needing a gentle but powerful nutritional boost.
From the feed, forage or roughage they eat.
It is if it's processed enough that the microbes in the cow's rumen can break it down and digest it. It would be a waste of money to feed if it's fed whole/unprocessed and not much nutrient can be gleaned from it by either the microbes or the cow.
You can't take it out of a cow. The cow has to be killed and butchered first, then the meat that is not suitable for use as steaks and/or roasts go through a blender to grind it all up.
