HUMAN NUTRITION

Detailed explanation-1: -Some of this digested food enters the bloodstream and travels to a bag called the udder, where it is made into milk that will come out of her teats, while the rest goes towards the cow’s nourishment. In a day, a cow spends about 6.5 hours eating and drinking all of her food.

Detailed explanation-2: -It takes one to three days for food to pass through a cow’s digestive tract, depending upon what she eats. A cow briefly chews food as she eats, breaking it into smaller particles. As she chews, digestive enzymes in her saliva are mixed with the food before it passes down the esophagus into the reticulum and rumen.

Detailed explanation-3: -Ruminant stomachs have four compartments: the rumen, the reticulum, the omasum and the abomasum. Rumen microbes ferment feed and produce volatile fatty acids, which is the cow’s main energy source. Rumen microbes also produce B vitamins, vitamin K and amino acids.

Detailed explanation-4: -A cow’s rumen is different because it functions like a large food processor. In fact, millions of tiny organisms (mainly bacteria) naturally live in the rumen and help the cow by breaking down plant parts that cannot be digested otherwise. These tiny organisms then release nutrients into the rumen.

Detailed explanation-5: -After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food to move through the entire colon.
