They are herd-oriented animals. As a cohesive group they feel safer when they eat and sleep together. This way one animal that is more alert than the others can be awake to sense any sort of danger that may approach their resting area.
Yes.
Hours at a time, they sleep this way also.
General urban ledgend states that, when it is going to rain cows lie down.
Yes, to chew their cud.
Where do cows lie? On their UDDER side.
Elephants do not lie down and sleep. They sleep standing. You know why? They are afraid ants might get into their trunks
Cows can give birth while standing up or lying down. It depends on the individual cow and her comfort level. Some cows prefer to give birth while standing, while others may choose to lie down.
Yes, though they like to stand around and ruminate (chew their cud) for a while first before they lay down to take a nap.
No. Cows are not capable of lying like humans are, in the context of the ability to not tell the truth. All animals, except humans, never lie no matter what people think.
The present tense spelling for "lie down" is "lie down."
They don't. This is a myth. Cattle will just keep on grazing or head for shelter when it rains. Most cattle don't give a hoot whether they get wet or not. If it's a light rain, they'll just keep grazing. If it's a heavy downpour or a cold rain that chills you right to the bone, then they will head for shelter (a grove of trees, a barn or a shed) and bunch up together to keep warm. An experienced cattle producer will tell you that it's not true that cattle will lay down when it's going to rain or even when it does rain. And even an animal scientist can tell you that cattle don't have this barometric-pressure sensing thing that makes them "have to" lay down right before it rains. The only time cattle will lay down, even when it's all together, is when they're chewing the cud or need a time to rest. Cattle are herd animals, and do anything together, from eating to sleeping to even mating.
Cows only lay down when they are chewing their cud and resting after eating their fill. They don't lay down for any other reason, even when a storm or rain-shower is coming or happens. See the related question below for more.
