It doesn't.
The brain.
Poor nutrition, disease, old age.
There is no such thing as "cow disease" unless you are referring to MAD cow disease, which is something else entirely.
It's not sad cow disease, it's MAD cow disease. Its a brain disease that can cause irrational behavior in cows.
We are aware of mad cow disease
Typically a cow with Johne's Disease (which is a disease where a cow has chronic diarrhea) is considered safe to be slaughtered for food.
She had Bright's disease and Mad Cow disease.
People do not get Mad Cow Disease. No human can get mad cow disease but humans can be infected by eating meat from a contaminated cow that has mad cow disease. The disease in people that has been associated with humans is called variant Creutzfeldt Jakob disease (vCJD) that is also a progressive fatal neurological disease.
The cow eats the grass; as the grass regrows, it takes carbon dioxide from the atmosphere into its growing leaves and roots (along with other nutrients) and stores the carbon molecules in the soil. The cow that ate the grass also has to excrete her wastes, which turns back into the soil through the act of decomposition. She also releases carbon into the atmosphere, but it is quickly put back into the earth by the plants that breathe it in and exhale oxygen through the act of photosynthesis.
Cow two:yes Cow one: are you worried? Cow one: no. Why should I? I'm an AIRPLANE
No, mosquitoes do not carry mad cow disease. Mad cow disease, or Bovine Spongiform Encephalopathy (BSE), is caused by prions that affect cattle and is not transmitted by insects. The disease primarily spreads through the consumption of infected animal products. Mosquitoes are not involved in the transmission of prion diseases like mad cow disease.
Under most circumstances, cows are not a danger to humans. However, eating contaminated beef can result in the spread of the deadly E. Coli Virus and Mad Cow Disease.
