She may die if not cooled or put in a cool place right away.
Mitochondrial respiration is the process in a cow's cells that releases heat. Mitochondria produce energy in the form of ATP through the oxidation of nutrients, resulting in the generation of heat as a byproduct.
No. A cow or heifer in heat will stay with the herd, or rather, the herd will stick with her.
If it's stuck open, no heat. If it's stuck closed, over heat.
it will explode!! or a certain parts will be unuseful
Only if the cow that they're mounting is in heat.
This really depends on the cow. Often it is the one that is being ridden that is in heat, however the one that is in heat can also ride other cows (and even the bull). The one that is in heat is the one that stands to be mounted and doesn't try to turn around and butt the other cow that had just ridden her.
No.
your car will over heat and you might blow your head gasket
Same as any other cow: around 24 hours.
No, the cow will not go into estrus after she becomes pregnant.
The rule of thumb is that you need to breed a cow 12 hours after you see her show signs of estrus or heat. A bull will typically mate a cow during her heat period, but not when she's not in heat, which is the rest of the 17 to 24 days that she's not in heat.
Heifers will show their first heat around the age of one year, depending on the heifer.
