Do birds feel pain, and do chickens feel pain?

Student. First, let's talk about examples. I think from our concept of human pain:

1.At least arthropods.

Most insects don't feel the pain we feel. The nervous system of most insects.

Only basic stress responses can be made.

Of course, there may be a few exceptions.

2.Lobsters and lower vertebrates among arthropods.

Fish are pain-sensitive, they have nociceptive nerves, and they can feel a certain amount of pain (it should be very mild), but they don't necessarily understand that it's called pain, and they don't necessarily feel pain. Amphibians.

and reptiles are similar to fish.

3.Higher vertebrates, such as mammals.

It is obvious that the pain nerve is relatively developed. They, like us humans, can feel intense pain and can truly understand "ahhhhhh

But even if I can't feel pain in a nervous sense, I still can't think that lobsters, insects, crabs, spiders, and octopuses don't feel pain. They also have a stress response that, at least as well as our sense of pain, reduces the likelihood of further harm. When insects, fish and shrimp are hurt by us, they do struggle, just like we struggle when we feel pain.

That is, we can't tell if they are aware of pain ...... through means other than nerve conductionNor can this hypothesis be falsified in the existing scientific framework.

Finally, most importantly, the definition. At the definition level, pain and pain are not necessarily the same thing. Because no one knows that bugs that don't have enough developed nerves and no consciousness don't feel bad when they are injured ( Although there is no pain, we can't know how they really feel.

To sum up: if we think that the definition of pain is pain, and agree that the pain sensation that is only felt by humans in this way of nerve conduction is real pain, and it is the only way to feel pain in the biological world. Well, these lower animals you are talking about really don't feel what we call pain.

Hello! Don't complain about anything else, the plant doesn't even have nerves, let alone the central nervous system, it hurts?? Pain sensation is achieved by neuromodulated action potentials, and your plant relies only on hormone regulation and secondary metabolite regulation, do you know how inefficient it is?

You've been cold for 800 years, and the excitement hasn't spread far yet. Oh yes, it's not even exciting, because there's no action potential.

It only represents a personal opinion, don't spray if you don't like it, thank you.

In humans, pain perception is a higher neural reflex formed in the cerebral cortex, and it was once thought that "lower animals" without brains would not experience pain.

But feeling is the most difficult thing for people to perceive, because most of the ways humans understand the world are still "pushing themselves and others", and if they have brains, it is difficult to imagine how animals without brains can form feelings.

At present, many people of insight are also reflecting on this long-standing understanding of anthropocentrism, but there is no way to say whether they are really sentient or not.

The main method now used is the method of behavioral observation, which looks at the response to injury.

The specific response of living beings to pain – you yourself can be the best example.

Using this as a criterion, then all animals should have a sense of pain, because all animals can react strongly to external harm. But in this way, it also means that single-celled organisms, paramecium, etc., also have a sense of pain, which is too far from people's perception, after all, single-celled organisms are still just a mass of autonomous cells in the eyes of most people, and stress and feelings are confused here.

By this criterion, do lower invertebrates, such as jellyfish or sponges, have a sense of pain? They don't have a brain, only the most primitive reticular nerves, and we don't know if they have sensory abilities.

Therefore, human beings can only be sure that organisms with higher brains must have a sense of pain.

Personally, I guess that squid pulls insects and other advanced vertebrates will definitely hurt.

That's right, every animal is a life, and as long as it's a life, it hurts.

This question should be asked "chicken, duck".

People don't know.

Chicken breast refers to the deformity of the sternum that bulges forward, most of the chicken breast is caused by rickets, and only a few children's chicken breast is congenital. Chicken breasts are difficult to detect in the early stages and can only be seen when the breast deformity matures. It should be done as early as possible**.

Chicken breast is caused by rickets, which can cause rib heightening, valgus, and severe respiratory function, but there is no pain.

Chicken breasts don't hurt, if a person's collarbone is too prominent, they call it chicken breast, and chicken breast is just an adjective.

Definitely.

Animals can also have pain during childbirth.

Because a lot of eggs can get bloodshot on them, can't they?

Words of unbelief. Go ask the hens. Ga.

Hehe, I'm speechless. Think about it. The excitement of the clucking of the hen when it was time to lay eggs. Hehe, you say it's painful or.

All animals, including humans, are in pain when giving birth!

I'm ready to learn "chicken language" now, and when I learn it, I'll be able to talk to chickens. I'll ask you when the time comes, hehe

Nonsense, otherwise the hen would cry so sadly!

Think about whether it hurts to have a child???

1.Allergy symptoms, but the allergen is not necessarily chicken or eggs, it may be something else, triggered by eating chicken or eggs (chicken, fish, beef, etc. are all foods that trigger allergies).

2.Go to the hospital and test for allergens, test them all, and find out the real allergens.

3.Allergies are caused by the immune system not having immunity to some kind of foreign cells (bacteria, viruses, worms, etc., many may be, you have to do the next test), usually eat more anti-allergy, immunity-boosting food.

4.Don't panic, many people are born with no immunity to a substance, it's not a disease, as long as you stay away from allergens.

Typical allergy symptoms, don't lie to you. Go to the hospital to check the source of the allergy.

Allergies, go to the hospital for a check-up.

I used to eat duck meat when I was a kid and would be like you.

It should be allergies.

Definitely, there is life.

Definitely, it's all alive.

Pain, in order to make their death happy and alleviate their guilt, so the professional butcher pursues an instant death.

Isn't this nonsense, it doesn't hurt for people to kill you.
