Grass, which is eaten by the cow, is used as an energy source for building and repairing body tissues like muscles, metabolizable energy, reproduction, etc. Thus grass doesn't go directly into meat production of the cow, which is why it seems like the cow is "so inefficient" at converting grass into meat. Grass is also a coarser plant material and is not a concentrated ration, which compounds the reason for grass being "inefficient" at being converted into meat. Typically 20% of what the cow consumes of grass and roughage is used as energy. The other 80% is released as "waste" back to the soil for plants to reuse and get their fertilizer from.
Quite frankly, if you want something more efficient than the cow, the man-made combine-harvester is the most efficient machine at harvesting grasses. It utilizes 90% of the grass harvested "converting" it into grain. But by no means will you get meat from it.
humans....we eat cows and cows eat grass...
They are called herbivores.
The hypothesis of "all cows eat grass" would be that every cow, without exception, consumes grass as part of their diet. This hypothesis can be tested through observation of the feeding habits of cows in various settings to determine its accuracy.
According to the related link below, the FAO estimates that there were 26.5 million dairy cows in the world in 2010. The statistic for number of beef cows in the world is more vague, because beef cows are lumped in with the "cattle" category, not individually as female mature bovines.
Oh, dude, a cow's niche is basically just chilling in the field, munching on grass, and producing milk. They're like the OG grass-fed, organic, free-range influencers of the animal kingdom. So yeah, their niche is basically being the laid-back, milk-producing, four-legged superstars of the farm.
Beef.
Beef cows = beef cows, so yes, obviously.
It's supplemental protein for beef cows that are on grass diets.
Bubba's Burgers down own any cows, but the beef they serve (Kauai Island Bubba's Burgers, see related link below) is indeed grass-fed.
Hamburgers = beef beef = cows Steak is from cows. So yes, cows are eaten.
None. Cows eat grass, hay, silage and grain, not any sort of animal meat like "beef nut."
Angus cows are beef cows, not dairy cows. Holsteins are dairy cows, not beef cows, which is where we get the majority of our milk from.
Ranches that are defined as companies, like those found in Montana and Alberta, for instance.
No, beef does not grow on a plant. Beef comes from the meat of cattle animals like cows, which are raised on farms for human consumption. The cattle are fed a diet of grass, hay, grains, and other feed to help them grow to the appropriate size before being processed into beef.
No. There are many cattle feeds that are vegetarian besides grass. The most common are corn and soy.
Beef comes from cows.
Both (they drink milk there as well as eat beef) but there are more beef cattle.
