Because cattle are ruminants and cellulose is broken down by the microbes found inside of the rumen and then digested further in the cecum. Humans do not have a multiple-chambered stomach nor a functional cecum, thus making digesting cellulose impossible. Cellulose only acts as a gut filler for humans, which is the main reason why plant matter passes through so quickly (in around 2 hours) in a human's digestive tract compared to meat, and compared to the time it takes plant matter to go through a cow's digestive tract.

Why is cellulose important to plant?
The cell walls of plants are made of cellulose. Approximately 33 percent of all plant material is cellulose. Humans cannot digest cellulose, but animals such as cows and horses can digest cellulose for food.
Why don't people eat things with very height levels of a cellulose?
people cannot digest cellulose but cows can
Why don't people eat things with very height levels of cellulose?
people cannot digest cellulose but cows can
What are some organisms that contain cellulose?
Cellulose is hard to digest plant material found in plants such as grass and leaves.Herbivores such as Cows and giraffes can digest cellulose.certain types of bacteria can digest cellulose as well.
How do termites and cows digest cellulose?
Inside the termites digestive tract, there is a symbotic microorganisms by the name of Trichonympha sphaerica who also has a symbiotic microorganism inside of it that digest the cellulose so that the termite can eat it. For cows it is the same they have symbiotic microorganisms inside of them that breaks down the cellulose but I am uncertain of the name.
Do buffalo have specialized digestive tract to digest plant cellulose?
Animals such as cows, horses, sheep, goats, and termites have symbiotic bacteria in the intestinal tract that contain the enzymes that allow them to digest cellulose in the GI tract. No vertebrate (animals with an internal skeleton) can digest cellulose directly; all must use the enzyme to break down cellulose.
What makes cellulose nondigestable in humans?
We lack the enzyme cellulase... and we don't have bacteria in our stomachs that do like cows, only bacteria can digest cellulose.
What effect does bacteria have on cellulose?
In cows and other herbivores, their natural flora of bacteria break down cellulose and make it something they can digest, but in humans our bacteria have no effect on cellulose, so for us it is indigestible.
Why do animals do not digest cellulose?
Humans are unable to get metabolic energy from cellulose because they lack the enzymes necessary to chemically break it down. Since the human body can't properly digest cellulose, it's passed in the feces.
Is cellulose digestible?
No, cannot break one of the beta bonds connecting the units of cellulose. Ruminants (e.g. cows, sheep) can however digest cellulose in their rumen, not themselves but because of the complex microorganisms living in their rumen.
Can you eat grass?
Grass has cellulose, which humans do not have the bacteria to digest, like cows or horses do. You can eat it, but you can't really digest it for energy. Also, something about not having a working appendix.
Why people dont eat things with very high levels of cellulose?
People cannot digest cellulose
