Paraglider pilot here, so I landed among the cow my fair share of times.

Cows are curious but shy, if you walk slowly they might come to have a look, if they get too close, something like clapping your hands is enough to have them running away. However, if the farmer didn’t took the veals the yet, they can be pretty agressive to protect their kids, in that case forgot what I said about “clapping your hand” and stay away from the herd. Note also that bull are less shy than cow.

From my understanding, you are pretty safe as long as you don’t provoke them (walking through the middle of them might be considered provoking) or near their calves. This article from the UK states “Where recorded, 91% of HSE reported fatalities on the public were caused by cows with calves”. Basically, mothers with a child are going to be very protective.

Cows are a domesticated creature, so they are generally docile, but I would exercise caution because if need be they will use their mass and strength against you. I’ve heard of stories of farmers running from cows and narrowly escaping under a fence. Most of these did involve a farmer trying to separate a calve from it’s mother. I’ve also heard stories of cows jumping fences.

And as far as memes go:

Cows, yes. Bulls, no.

Cows’ll usually retreat from people. Or if they’re curious, they’ll approach but not too close.

Just don’t walk behind them, or they might try to kick you.

Bulls are territorial. Stay the fuck away from 'em.

As the UK’s deadliest animal, cows attack between three and four thousand people every year.

An expert has revealed this figure may continue to rise. Between 2018 and 2022, more than 30 people were killed by cows, according to the UK Government’s Health and Safety Executive (HSE).

Depends very heavily on the cows. Cattle rancher here. Be careful about it and *most cattle are OK to walk among.

Generally speaking, most farm cattle are timid towards people. They may come check you out and encircle you as a herd, but will usually scurry away if you move suddenly, and don’t care if you’re just in the field with them. They are herbivorous herd/prey animals, after all. The cattle my parents raise, perfectly safe to walk through. Hell the calves will often come up and sniff you out and rub up against you.

Some remote range cattle can be more wild. They might take off running if they see you within a half mile, or they might come running towards you if they deem you a threat.

The real danger often lies with bulls (hanging balls and huge shoulder) or cows with young calves (<1mo old). Both of these can be very unpredictable.
I’ve interacted with some bulls that were as gentle as can be and some that would rip your skin off if you weren’t on the other side of a panel. You should never go into a paddock with an unknown bull, ever.
And even the most timid cow can start squaring up if she has a very young calf still in need of protection.

It’s something you mostly have to learn how to read. Cows are expressive. They have body language. They speak with their head and their tails, and they look with their ears. For me it’s easy to tell if a cow is safe to approach, but it is a learned skill.

When you approach cows, make noise. Nothing racocious but just talking in a firm tone to them is enough. Make sure the herd olknows your approaching long before you get close enough to be a danger, never suprise a cow. Always keep a distance of minimum 30 feet unless they approach you themselves out of curiosity.

A head and/or tail held very high means they are alert and focused on you, this usually means they are nervous and about to fight-or-flight. Back off slowly and try not to turn away.
If a herd dispersed while grazing begins to bunch up together, that also means they’re getting nervous. Just avoid the bunch and walk away from whatever direction they’re heading.

A head held low while looking at you, or still grazing means they are relaxed. They dont usually lower their head to “charge” like in the cartoons until they’re already moving. You’re new to the field so they’ll always look at you. Move smoothly and steadily, they won’t bother you.

If there was a calf or bull around I wouldn’t walk through.

You can yell at them and they might disperse. If they don’t then you’d be able to walk through them.

Cows just don’t like to be startled, that’s about it.

(also keep an eye out for where you’re stepping)

It really depends on what breed and how they were raised. In the Alps, there are almost anually reports of wanderers being attacked or even killed by cows. They often are with their calves for a longer time, are less accustomed to (strange) people and usually a fully intact male is in the heard that can get really protective.

Approach them with caution, watch their behaviour closely and use common sense. That’s what I do and for me that works.

Adding to what the other comments have already said: Don’t bring an unleashed dog on a cow pasture. You’d think that’s common sense, but apparently it’s a bit of a meme in Austria and Switzerland that every few months some German get’s trampled by cows because their totally friendly dog ran towards the cows and they felt threatened.

Cows, sure. Just don’t startle them or go near their calfs. They’re mostly just curious.

Bulls, only if you have to, but make it quick and stay as far away from them as you can. They’re fiercely territorial and not afraid to show it.

Stampede is the most common cause of death for backpack tourists in Australia. It may tempting to jump fences for a little shortcut, but many cows do not tolerate home invaders.

They’re mostly safe. Don’t taunt them, don’t get too close to them (specially not to veals and bulls), and eventually they’ll see you as “safe to ignore”.

Generally? Yes. Cows are animals. They will react to situations. Especially to you appearing between them and their children. Bulls can be aggressive, but that doesn’t mean that they always are.

a big factor here is dogs. if you have your pet with you on a lead, and there are calves(baby cows) in the field, sometimes a normally docile cow herd will be very protective of their offspring. generally if there is no dog, cows realise you are not a threat.

If I have to give only a binary yes/no answer, the answer is no. In reality, there are lots of variables ranging from breed, pen size, herd makeup, season, socialization, hunger, weather, and even more that would factor in. That’s without considering the other variable of you as a person they don’t know.

Edit: that’s not even to say the cattle or a bovine would intentionally hurt you. They’re big, sometimes clumsy, have horns, etc. I follow some youtubers who have been raising cattle anywhere from a couple years to most of their lives and they still are very careful in a lot of their movements and interactions.
