weasel wishes the chicken a new year - I don't have good intentions . Speaking of this idiom, I think everyone is familiar with it. People's evaluation of weasels has always been relatively low in life. They believe that it steals poultry, spreads bacteria, and even some places have attached mysterious colors to it, believing that it is a great immortal who has cultivated into a spirit. There are various legends about " Wong Tai Immortal " and "weasel into a spirit" emerging one after another.
"Great Immortal" Weasel
Putting aside these subconscious views, weasel is actually not mysterious and not as unbearable as people imagine. Like all kinds of creatures, it is just an ordinary species living in this world.
Weasel scientific name " Weasel ", is a small carnivore . It belongs to the class mammal and on biology belongs to the class mammal and ferret family . The body length of adult weasels is generally 28-40 cm , the tail length is about 12-25 cm , and the weight is 210-1200 grams.
Weasels like to live in river valleys, villages, cities and mountainous areas. They are omnivorous animals and mainly feed on small mammals. Wheels living in rural areas often sneak into human residences to steal poultry and small livestock. Small animals such as mice and rabbits in the wild are also the objects of their prey. In addition, some amphibians , fish, bird eggs , insects and carrion are also included in their recipes. When seasonal changes and meat food is difficult to catch, weasels will also collect pine nuts to feed.
The thing that weasels hate the most is the stealing of poultry. In rural areas, weasels often attack at night, and birds such as chickens, ducks and geese are the targets they hunt. Like many weasels, weasels have odor glands in their bodies, which can expel odor. This is their only self-defense weapon after encountering danger. This self-defense method can be said to be their "magic weapon" to save their lives at critical moments.
There is a pair of soybean-shaped odor glands on both sides of the anus of the weasel. When they encounter strong enemies running away, they can burst out an unbearable secretion from the odor glands. If this secretion is toxic, if it is ejaculated on the head, the mild case will feel dizzy, nausea and vomiting, and in severe cases, it will fall to the ground and fall into coma.
When encountering threats, this gas plays a role in paralyzing the enemy. In ancient times, people did not have a deep understanding of the habits of weasels and did not conduct detailed research on the body structure of weasels, so they regarded this stench as their "evil art", which is also one of the sources of various mysterious legends about weasels.
Weasel belongs to the "three-have" protected animals in . "Three-have" refers to the beneficial or important economy protected by . Terrestrial wild animals with scientific research value , "has been included in the "National Key Protection Terrestrial Wildlife List".
In recent years, with the continuous expansion of the city's scale, the environment suitable for the survival of weasels has been compressed, and the number of weasels has decreased sharply. It is difficult for us to see weasels. In addition to this reason, it is more important that people hunt weasels for their economic value.
Weasels have been over the years It is used by the people as medicinal materials. It has a good relief for some diseases. It is also cheap and can be used well with other Chinese patent medicines.
Weasel's fur is also very useful. Their fur can be used to make leather bags, fur coats, etc. Friends familiar with calligraphy should all know that there is a brush called "Wolf Hair" . This is a relatively high-end brush. Some ancient literati and poets were honored to have a wolf hair brush, and its raw material was the fur of the weasel.
Because of this, coupled with the subconscious people's poor evaluation of weasels, over the years, weasels have been hunted in large numbers, which has led to a sharp reduction in the number of weasels. weasels have a low reproductive rate, only one child a year, and one child is about 2-8 . According to the actual living rate, the number of new weasels born every year cannot resist large-scale hunting.
Many breeding difficulties
The contradiction between growing demand and species protection has begun to overlap. At this time, someone may ask: Since the number of wild weasels is not enough, why not artificial breeding?
In fact, many people have proposed and practiced this idea, but the results are mostly not ideal. Due to the living habits of weasels and the lack of relevant breeding technology experience, it is still difficult to see large-scale weasel breeding sites today.
For economic considerations, most of the previous research on artificial breeding was in livestock, poultry and some endangered species. Weasels have been unpopular breeding varieties for a long time in the past, and few people have specifically studied its breeding technology. Therefore, in this regard, there is currently no systematic reproductive experience for reference.
Compared with previous artificial breeding species, weasels belong to the "difficult" category, because there is no artificial breeding experience, weasels have few seedlings. In terms of diet, weasels are omnivorous animals and have sufficient food sources, but how to match its recipes is also difficult to determine because they have no experience. Once there is an accident in diet, disease treatment is another big problem.
friends who have raised livestock in rural areas know that animals like pigs, cattle and sheep are very reproductive rates, and they have to give birth to several births a year, which ensures the annual birth rate, which can greatly reduce costs and increase the profit of . The birth rate of weasels has always been relatively "Buddhist", which is very troublesome.
As we mentioned earlier, weasels only give birth to one child a year, and one child is about 2-8 . Even in this precious baby, newborn cubs will inevitably die due to various reasons. In this way, only a few artificial weasels can be bred in a year, and the same investment cost has little return, which invisibly increases the industry risks of weasel breeding.
Another important reason for the artificial breeding of weasels is its habit . Because of its thin body, it can easily escape even if there are small loopholes in the field. Weasels are aggressive by nature. If the traditional captive method is used, group of weasels gather together and easily bite each other. Once the fur is damaged, the weasels will lose most of its economic value.
Now the artificial breeding technology of weasels is still in the exploration stage, so the number of weasels is mainly increasing in wild groups. If we can put aside prejudice, weasels are also one of the thousands of living beings. Although they will conflict with humans in some aspects, they are not as unbearable as we imagined. Perhaps one day, if artificial breeding technology makes a breakthrough, we may be able to see more docile weasel species that do not carry bacteria and do not smell, and they will also come to humans in a more pleasing image.
