Do  cows sleep standing up and how much sleep do they need?
409130
Cows usually need about 3-4 hours of sleep each day.  Since such a big part of their existence is eating and digesting, they need more time for that than sleeping.\n\nCows do sleep standing up, but they also sleep lying down.  Just depends on the cow, I guess.  There is a lot of speculation on why cows sleep up or down.  Sleeping while standing could come from the need to flee if a dangerous situation arose suddenly.  It could also have to do with the need of being cooler in the heat.  Just like cats exposing their bellies to those they trust, cows may choose to sleep lying down in situations where they feel safe.  Like maybe if some of the heard is standing while others aren't...or maybe they'll lie in a protected stall...or maybe they lie down to get warm.  Who knows!  Too bad we can't ask them!

Sometimes a cow has to be tipped (we actually call it taking them down) if they need to be doctored or something.  You grab them by the tail and pull them sideways.  Why would it hurt a cow any worse than a person?  Yes, cows can get back up, yes, they do sleep laying down and yes, you could get your teeth knocked out trying it.  Cows can kick sideways as well as backwards and it's not real easy to sneak up on a cow, but if you do, a full grown cow can weigh over 1000 lbs. so you better be fast and strong.  Better not pick on her calf either, as most cows are really protective of their babies and will hurt you.  I wouldn't worry too much about cows.  They can pretty much take care of themselves as far as tippers go.

I think its not really the sheep or the fence has much \nto do with it.  What makes us tired is the brain work it\ntakes and all the imagination involved, plus keeping up with what number is next  etc... Alot to think of with your\neyes closed and laying in bed does the trick.

You have the question backwards. The vast majority of animals can not sleep standing up. An inability to sleep standing up is the default trait, it is the primitive condition. Therefore the real question is why was an ability to sleep while standing selected.\n\nOur earliest ancestors were cold blooded and couldn’t move at night anyway, so obviously it made no difference whether they slept lying down, standing up or hanging form their tails.\n\nOur first warm blooded ancestors were nocturnal and lived in burrows and hollow logs. In those conditions it makes no difference whether an animals sleeps standing up or lying down. \n\nOur first primate ancestors were arboreal and either slept in dreys, in hollow branches or hugging the branch of a tree. Under those conditions it would be positively dangerous to sleep standing up.\n\nOur first ape ancestors either retained the trait of sleeping hugging tree baches, or they built nests on the ground. Once again it would be positively dangerous to draw attention to yourself by sleeping standing up.\n\nOur first hominid ancestors presumably built nests on the ground. Once again, the idea of standing upright in the middle of a savanna while asleep is pure suicide.\n\nI really can’t see why you believe it was ever beneficial in our evolutionary history to sleep standing upright. What possible advantage could it give to draw attention to a helpless sleeping animal by having it stand up?\n\n\n>>>>In a prehistoric world would we not have been more at a disadvantage for sleeping while down..\n\nCan you explain how we could possibly be at any disadvantage for sleeping in a position that minimises our visibility to predators?\n\n>>>>or sleeping for that matter.\n\nWell if you are asking why animals sleep at all that is an entirely different question with completely different (and less certain) answers.\n\nIf we accept that animals do need to sleep then I can't understand why you think standing out against the background would be beneficial.

Cow's teeth are different from ours. On the top front, cows have a tough pad of skin instead of teeth. They have 8 incisors on the bottom front and 6 strong molars on the top and bottom of each side to grind their food. Cows have a total of 32 teeth.

Fish sleep just like regular animals.  Thier basic motor functions still maintain, like movement.  Dolphins and other mammals shut down a half of thier brain at a time so they still come up for air.  Certain fish do this too because they don't pump water over thier gills, there needs to be motion to mover the water over them.  Hope that helps.

I can't stop laughing at the word moobs...what was the question\nOh yes, change your diet, you can sit up, crunch till the cows come home...but until you change the diet the cows will remain in the moob zone.

Probably not as their bodies use only the energy(fat) they need to survive the long sleep.

sleep requires different levels of total relaxation of the body muscles (except the diaphragm and the ocular muscles, and i'm talking only skeletal, voluntrary muscles) as well as cortical de-synchronization. i bet you don't want to be standing up for this. have you ever seen a narcoleptic? they go straight into REM sleep which is the strongest point of this inhibition. the fall straight to the ground.

let's see a typical day starts out at 3am. saddle up go eat feed the cattle ride around over the country see if any of them are sick or have something wrong with them check fence. write everything down in your herd book. make sure you take better care of your horse and saddle. and they will take care of you there is so much more winter time you move the cattle in closer. spring time it's branding and cutting. it's a miserable life, take it from me. but it is also fun and enjoyable. if you like living rough.

average cow weighs 1000-1100 pounds.  cows refers to females kept for breeding purposes, they do not enter the food chain until they either become old or unproductive.  they are a low quality beef product, hamburger, bologna etc.\n\n\nsteers and heifers(young females) become the top quality beef products---steaks, roasts + hamburger too.  they are usually 2 years old or less at processing.  wt-- about 1000 pounds.  about 65% of total weight becomes saleable beef.  the rest is hide, intrals, bones, waste. \n\ncosts vary, a calf changes hands several times before it winds up in grocery stores.  the farmer that raises it gets his money. he sells it to either a feedlot or another rancher that leaves it on grass pastures for several months.  the processors buy it from the feedlots.\n\nan average quality steer that sells to a processor weighs 1000-1200 pounds, an average price paid is 75 cents per pound.  prices change all of the time

Well, sleep is a period of regeneration.  Sleep deprivation, leads to decrease of brain metabolic activity, weakening of the immune system (i.e. drop in white blood cell count).  And in children the growth hormone is released during sleep.  Generally during sleep the rate of production in cells increases and their rate of protein breakdown decreases. \nInterestingly i can't remember where i read this, but the amount of sleep required for a species depends on their metabolic rate, and the metabolic rate increase as the size of the animal decreases.  So a mouse needs around 18 hours of sleep to regenerate properly, whereas an elephant needs around 3. But don't quote me on those numbers.

When human and animal is lying down, all muscles are relaxed, so brain is relaxed too, and sleep is more comfortable, but some mamalians, for example horse can sleep standing, because it's body is adapted.

Well I don't know your aunt's regular sleeping habits, but if you're asking whether women with new babies tend to be up at bizarre times of night the answer is yes...although that doesn't mean she's up NOW. If she's managing to catch some sleep between feedings, burpings, and changings, you probably don't want to wake her.
