In nature, there are many symbiotic animals and plants, such as chickens and foxes, cats and mice are compatible, and anemones and hermit crabs, rhinos and rhinoceros birds are symbiotic. There are also some animals that are obviously unrelated to each other, but they are divided into upper and lower positions, such as snakes and geese.
Tips: Tom and Jerry is a 1939 animated film produced by MGM Pictures depicting a pair of intolerable rivals: the war between Tom Cat and Jerry Mouse.
As one of the "three hegemons" in the village, the big goose can not only stop the children from crying at night, but also chase the dog to prevent theft, which is the best choice for guarding the portal.

Even Su Dongpo once wrote in the "Notes of Qiu Chi": "Geese can police thieves, but also snakes." Its dung kills snakes, shu people raise geese in the garden pond, and the snakes are far away.... ”
Tips: As a common poultry, geese have special living habits, for example, they are water-loving, alert, cold-tolerant, and regular in life. Goose has strong disease resistance, small breeding pollution, and as a green food, it is more and more loved by people.
So why are snakes afraid of geese? Could it be that goose dung contains ingredients that can kill snakes?
Why are snakes afraid of geese?
The snake, as the killer of the animal kingdom, is deeply rooted in the true legend of the assassin's one-shot death, and is the representative animal of the word sinister and cunning. Whether in the movie or the novel, he appears as the villain boss of the movie, rendering a cruel and bloody sense of atmosphere. Snakes, which are born cold-blooded animals, have poor vision but a very keen sense of smell, and most of the time determine the position of their prey through their sense of smell and infrared heat radiation.
Although the snake is relatively good at hunting animals, there are still natural predators in nature, birds. There are still many birds that eat snakes in nature, there are eagle falcons that eat snakes, there are snake eagles that specialize in eating snakes, and heron birds sometimes eat snakes.
Tips: A snake with an elongated body divided into three parts: head, torso and tail. The habitat of snakes varies from species to species, and the habitat environment is diverse, some live in caves, some live on the ground, some live in trees, and some live in water.
And the goose, although it also belongs to the birds, has the title of a bully of birds, childhood nightmares, dog chasers, etc., but it does not eat snakes, the goose said that he does not want to eat such a disgusting thing, okay? The goose is also a "decent man". There are two sources of geese, one is a Chinese goose and the other is a European goose. Among them, the ancestor of the European goose is the gray goose, and the ancestor of the Chinese goose is the Hongyan, which was caught by the ancestors of our country about 6,000 years ago, sealing the debauched and free-loving soul and domesticating it into a tool goose for the janitor. The difference between the two kinds of geese is relatively large, the European goose neck is short, the neck is thick, and there is no raised sarcoma on the head, while the goose neck in China is slender, the appearance value is extremely high, and there is a raised sarcoma on the head.
Tips: The Goose is a large waterfowl. Its natural habitats are lakes, ponds, rivers, swamps and their vicinity on open plains and plain meadows. Sexually happy flocks, often in groups, especially during the migration season, often in large flocks of tens, hundreds, or even thousands.
The fighting power of the goose is extremely strong, and it can be called the "fighting race" of birds. Although geese have been domesticated as poultry for thousands of years, but the bones of geese still hide wild, their territorial awareness is very strong, once someone or animal invades their territory, these sensitive and swift geese, will shout loudly, flapping their wings, flying forward with a beak to hit or twist. Because the goose is a gregarious animal, don't think that its shouting is just to scare you, in fact it is calling for a companion, inviting the goose to besiege you.
Although the fighting power of the goose is very explosive, in fact, people are still a peace-loving herbivores, and snakes are not my dish. The main food of domestic geese is grass, and adult geese can consume about 2 kg of grass per day. In addition to grass, geese also eat a variety of grains, as well as aquatic plants, and occasionally eat small fish, shrimp and insects to improve their diet.
Tips: Domestic geese mature after about 9 months of growth. In the rearing environment, male geese are 1.5-2 years old, and female geese begin to mate at more than 2 years old, generally starting to lay eggs in the spring; dozens to 100 eggs are laid every year, and the geese can hatch on their own, and the incubation period is 28-33 days.
Geese do not catch snakes, snakes are cold-blooded animals, shadow killers, and animals that can even swallow elephants in legend will avoid the places where geese are infested. Has the name of the ferocity of my goose been preached to the point where snakes can't avoid it? Why are snakes afraid of geese? There are several theories about this.
The first is the first, because goose feces contain male yellow. I believe that everyone has watched the TV series "The Legend of the New White Lady" when they were young, and there is a plot in which Fahai deceives Xu Xian and gives Xu Xianxiong yellow wine that he can drive away evil spirits and let him drink with his wife. So the innocent Xu Xian believed, so he went home to give his wife Bai Niangzi a drink, and as a result, bai niangzi wanted to show her original form, from a great beauty who fell into the country and the city, to a big white snake, is it simply a childhood shadow? From this, it can be known that the snake is afraid of male yellow.
Tips: Xiong Huang, chinese medicine name. It is a sulfide mineral male yellow, which mainly contains arsenic disulfide As2S2. It has the effect of detoxification and insecticide, dry and wet expectorant, and malaria amputation.
Why is there a male yellow in the goose feces? This is because in ancient times, people did not have special feed for geese, they were stocked for geese to find their own food, which may have male yellow grass, so that after excretion, their feces will have some components, and snakes are afraid of male yellow grass, so they will drive the snake away. But later someone did a special experiment and found that the snake is not afraid of male yellow, snake is afraid of male yellow wine, mainly afraid of alcohol. Because the skin of snakes is respiratory and permeable, amphibians are very afraid of volatile substances seeping into the bloodstream through the skin. Therefore, snakes will also be afraid of substances such as cigarette bag oil that contain heterocyclic aromatic hydrocarbons.
Tips: According to the relevant regulations of our country, the driving person has a blood alcohol content greater than or equal to 20 mg per 100 ml, and a blood alcohol content of less than 80 mg per 100 ml is driving after drinking alcohol; A blood alcohol content greater than or equal to 80 mg per 100 ml is drunk driving.
Another theory is that because goose feces contain ammonia, ammonia is also a volatile substance, some people think that snakes are afraid of ammonia in goose feces.
Some people say that because the goose has super high combat effectiveness, the snake is afraid of the goose itself. A goose is a very sharp hearing, quick response, and extremely alert animal. And their territorial awareness is very strong, as long as someone invades their territory, they will receive the goose wing flapping and group beating warning, compared to the lone ranger's snake, the goose is not only strong in combat or social animals, at any time is a large group of geese bullying an opponent, because the goose is more powerful than the snake, the snake has a strong fear of the goose. Although snakes do not have good vision, their sense of smell is relatively sharp, and they will avoid it after discovering the smell of geese. The same is true after the smell of goose dung is discovered, and it will not be approached, so raising geese can prevent snakes.
Tips: There are many varieties of geese, the main species in China are seed goose, open-eyed goose, Sichuan white goose, Zhejiang east white goose, Taihu goose, goose goose, lion head goose, anhui white goose, etc., foreign goose varieties are Rhine goose, Langde goose, Emden goose, Toulouse goose and so on.
The above several statements, only the last kind of combat strength is more reliable, other male yellow theory and ammonia theory, are not very reliable, because since modern times in order to increase the yield of geese, we have adopted a more scientific means to raise geese, geese now eat high-nutrient artificial feed, no longer eat grass, so in fact, the current goose dung almost does not contain male yellow, the content of ammonia is almost nothing. And chicken and duck dung also contain ammonia, and snakes are almost not afraid of them, generally encountered as a small dessert one bite and go down. The others are even more nonsense because goose droppings can corrode the skin of snakes.
Tips: Snakes swallow animals that are much larger than themselves, mainly because first there are two jaws that can be separated from each other and move independently; secondly, there are two separate suspensions, the mandibular joints, so that the snake's mouth can open at a large enough angle.
Animals are born with the instinct to seek advantage and avoid harm, which is a life-saving magic weapon that evolved in the cruel nature. Snakes can survive many biological extinctions until now, in addition to its opening can manage the diet of several days at a time, more importantly, because it is originally a conspirator of the yin rubbing, so the snake must have encountered a "natural enemy" that is extremely threatening to its life, and will avoid the goose like a snake scorpion and run once.
Ingredients in goose dung
In the ancient books and the memories of the old man, it is clearly recorded that the snake is afraid of the goose feces, but we have previously ruled out the male yellow theory, ammonia theory and so on of the goose feces. So it should be the other ingredients in the goose feces that drive away the snake. Let's take a look at the main ingredients of some goose droppings.
Tips: Snake badger, also known as gray badger, slender body, flexible body, mostly inhabit the tropical jungle, prey on small animals, also eat cobras, strong resistance to snake venom, produced in Yunnan.
The main components of goose feces are some metabolic substances in the goose's body, food that has not been digested, some shedding substances in the digestive tract, and microbial bacteria and secretory substances in the intestine, and sometimes small objects such as feathers or eggshells appear in the goose's feces. Because the intestines and stomach of the goose are alkaline, the feces excreted by the goose are naturally alkaline. In this way, it seems that there is no special substance in the goose's feces, which is the same as most poultry.
So what causes snakes to avoid geese like water and fire? Some people say that because of the male yellow, the male yellow is of course a detoxification and insecticide, but it is not omnipotent, and the previous test has proved that the male yellow is useless, only the gas produced when the male yellow is burned in large quantities, it will make the snake with a keen sense of smell feel afraid to escape, but the goose feces do not contain the male yellow, naturally there is no pungent smell that makes the snake leave.
Tips: Poultry refers to artificially raised bird animals, mainly for their meat, eggs and feathers, but also for other uses. Generally pheasant and duck, such as chickens, ducks, geese, quails, etc., there are also birds of other families such as turkeys, pigeons and various songbirds.
Although goose dung is not a good thing, it has a lot of effects. The poultry of the goose should be a larger poultry, and it is basically a group, and the amount of feces produced every day is very considerable. So how to deal with this feces is a problem, but how is it so difficult to get hard-working Chinese? Goose manure mainly contains chemicals such as nitrogen and phosphorus, which are more useful as fertilizers than chemical fertilizers in improving the fertility of the land, and are natural organic fertilizers. In addition, the acidic substances formed after the decomposition of goose manure have a great effect on the nutrient absorption and water regulation of the soil, which can not only improve the yield of crops but also can be used as raw materials for biogas digesters. However, the disadvantage of this kind of manure as fertilizer is that it is relatively dirty and easy to pollute the environment.
Tips: A digester is a biogas-making facility. Biogas is a kind of combustible gas produced by organic matter in an anaerobic environment, under certain temperature, humidity and pH conditions, through microbial fermentation.
What is Cryptosporidium?
Regarding what causes snakes to be afraid of geese, someone has done a lot of experiments and finally discovered this long-hidden big boss behind the scenes, which is Cryptosporidium. The worm was detected in the feces of geese. Cryptosporidium is an extremely tiny coccidioid parasite, mainly cryptosporidium microsporidium, which is widely lived all over the world and can be said to be a global virus. After infection in the human body, it can cause low immunity, and this insect has been considered an opportunistic pathogenic protozoa of AIDS, one of the causes of AIDS.
For most mammals, diarrhea caused by cryptosporidium can be cured by its own immunity, but for newborn or immunocompromised animals, Cryptosporidium can multiply rapidly, accelerate the deterioration of the disease, and lead to death.
Tips: Cryptosporidium is very infectious, and the cryptosporidium it causes is a worldwide zoonotic disease that causes severe diarrhea in mammals and respiratory diseases in poultry.
Compared with mammals, which can rely on their own immunity to resist the attack of Cryptosporidium, reptiles are difficult to resist, especially snakes are most afraid of Cryptosporidium, and once the snake is infected, it means that the death knell has been sounded and death is coming. Because the snake is not infected with it, the incubation period is long, once the onset is like a person to the end of the cancer, it looks like nothing happened, in fact, the body has been hollowed out, the whole disease has been irreversible. Infected snakes may die of acute illness immediately, or they may wait for a year or two or a few months to die in a mood or incubation period.
The life history of Cryptosporidium is relatively simple, and the reproductive methods include asexual split proliferation and spore reproduction and sexuality in the same host. Egg sacs are infectious when excreted with host feces and enter people or animals after being ingested by humans and susceptible animals. The worm has a very long life cycle and incubation period, can maintain vitality in an environment for several months without dying, and has strong resistance and tolerance to temperature and disinfectants.
Tips: Cryptosporidium mature oocysts have four spores, these spores follow the digestive juice into the intestine, the spores escape, invade the intestinal epithelial cells, develop into a trophozoite, after 3 nuclear divisions to develop into an ICUS containing 8 mesozoites, the entire infection takes 5 to 11 days.
After the snake is infected, in the later stages, its stomach tissue will grow and fibrosis, the stomach will be enlarged, abdominal pain will begin, then the stomach will rupture, local bleeding, cell necrosis, insidious cunning, and the cold-blooded assassin snake will die for a lifetime.
The cryptosporidium contained in goose feces poses a threat to snakes, just as the current epidemic of viruses poses a danger to humans, and snakes infect Cryptosporidium, just as humans infect Ebola, with little treatment.
