It depends on whether they've been lacking mineral for a long period of time or not. Usually when cattle have not had access to a certain type of mineral or even a mineral block for a long period of time, they will try to "eat" as much of it as they can until they are satisfied. You may say that they can eat too much mineral in one sitting, but often the level of mineral that a cow ingests is not enough to cause significant toxicity to her. Most of it will be expelled out of her system as feces and/or urine.
But, if you keep up with a good mineral program and keep adding the same minerals that your cattle need, they won't over indulge on it because it's in their system and they're not deficient for it.
They can, just not too much too suddenly.
No.
No, the cows are too big to eat.
In modern times, most Americans and other Westerners consume far too much of the mineral
No. Prairie dogs are ground squirrels (some people call them gophers), which eat mainly insects and vegetation. They are much too small to eat cows, nor do the like eating carrion (meat off of dead animals).
HUMANS. Coyotes (yes, they will eat grass, too!).
Ethical egoism
Yes just as cows and elephants do too!
Yes, cows can eat mangoes, and they often enjoy the sweet fruit. Mangoes are not toxic to cows and can be a nutritious treat, providing vitamins and minerals. However, they should be fed in moderation and as part of a balanced diet, since too much fruit can upset their digestive system. Always ensure that the mangoes are ripe and free from any mold or spoilage before offering them to cows.
You can eat too much of anything.
This could be for a number of reasons: they are eating too much grain before eating hay, they are sick, or the hay could be molding or tasting bad.
For the same reason we eat cows, pigs, chicken, lamb, goat, etc. It may seem offensive to us, but we eat animals that are considered sacred to other cultures, too. Did you know that in India, cows are viewed as sacred?
