How Do Cows Get Muscular From Eating Grass? 🐄🌱💪

Ever wondered how a huge muscly bull gets all that protein from just grass? 🤔

Here’s the wild truth most people don’t know:
Cows don’t get protein from grass—they get it from bacteria! 🦠

Grass contains cellulose, and special bacteria in the cow’s rumen break it down into sugar.
Those same bacteria multiply like crazy, and then…

The cow digests THEM for protein!

That’s right—bacteria steaks are the secret behind bovine gains!

And unlike cows, we humans can’t digest cellulose, so we rely on cows for that rich protein source.

Glad to see most of the comments are from people whom understand cows eat for 80% of the day just to get enough nutrients AND they have 4 stomachs to process this hard to digest grass. Vegans be like "but it's all natural" - so is meat.

They have 4 different stomachs ...humans don't

[fuswatenetke]

Bovines have four stomachs:

Rumen: The largest compartment where food is stored and fermented.

Reticulum: A honeycomb-shaped compartment where food is further processed.

Omasum: A compartment with folds that absorb water and minerals.

Abomasum: The true stomach where food is digested by enzymes.

He's half right. The bacteria turn some of the cellulose into sugar which the bacteria eats and then creates short chain fatty acids. The cow's protein comes form the bacteria, but it's energy comes from fat produced in the rumin. Cattler are often in ketosis when eating grass. When they eat corn, they can produce enough sugar to get "fat". That's why grass fed is leaner and healthier.

To make protein you need amino acids. To make amino acids you need nitrogen. This applies whether you’re a cow or a bacterium. The bacteria in the cows stomach cannot fabricate nitrogen without a source - the bacteria also need exogenous protein to grow and multiply. So the cow has to eat some protein to feed the bacteria. Grass is low in protein, but not completely devoid of it. The cows have to eat a lot of grass to get the protein that their comensal bacteria require.

[John-qnex]

He kind of skips one of the key points, where the bacteria are capable of generating extra amino acids and proteins out of nitrogen. That's the point that makes the rest of it significant.

If only people had multiple stomachs...

[valaurijune]

Alfalfa means father of grass, it contains all 23 amino acids which are the building blocks of protein. Thats an important point that seems to be left out.

[ParkedIdeas]

Tell people that if cows were eating meat they would be ok with 1-2 kg per day but they need like 30 kg of grass for the same amount of protein

[andrewzhuk]

I want to say 'Hi' to everyone who said "If bull can grow muscles being vegan, I can too" haha.
Good luck 😉

[gerardmichaelburnsjr.]

Excellent. Clarifies an important point.

[samuelmaina]

It's really great to finally get to understand this information. I've never really understood how the cows convert the grass into muscle tissues

[nacholibre]

Im just glad i dont have to eat grass for 16 hours a day. Glad the cow does the hard work for us 🥩❤. All praise the food chain. And our position in it.

[xscorcher]

I sure am glad that at the end of the video you clarified that humans and cows are not the same

[arthurlouis]

What he forget to add is the bacteria in the cow's gut can use urea to make amino acid. Farmer often add chicken poop to cow feed because of this. The cow also direct the urea from it's blood to it's gut so the bacteria can use produce the amino acid

[ScottDownie-dn]

One stomach 4 compartments, not 4 stomachs, but thank you for explaining to everyone that humans can't build protein from plants because our one compartment stomach 😂

[thecriticalobserver]

On related note. When you eat grass fed beef, (as opposed to grain fed cows) it will raise your testosterone levels

[landrelalonde]

Now try to imagine how much a plant eating dinosaurs had to eat.😮

[muhdaqil]

The lesson was, eat bacteria to get muscle

[maiqueashworth]

A wild bull, for example a Gaur in India, which receives no additives, gets all its food from the plants it eats. Bacteria are necessary to break down the cellulose, which is normally indigestible carbohydrate, so that the bovid can obtain energy from it. The bacteria are then digested in another stomach, and the bacteria do contain protein. The only place the bacteria can get that protein from is the plants the bacteria ate. Leaves are actually quite high in protein. However, it's difficult for humans to eat only leaves because there is so little energy in them, and we can't digest the cellulose
