A tourist asked curiously: "I heard that only the leader of the wolf pack has the right to mate and can breed offspring?" ”

Fang Ye shook his head and said, "What kind of alpha wolf rules the wolf pack, gives priority to enjoying prey, and has the right to mate, these rumors have been refuted by the wolf's field observation. In fact, the female wolves in the pack give birth to cubs, and the wolves raise them together.

Several female wolves are pregnant and give birth to cubs, when the wolves go out to hunt, the wolf cubs will be gathered in a cave and a female wolf will be taken care of as a nanny, which saves wolf resources and allows more wolves to devote themselves to hunting. ”

Our other female wolf, baby cabbage, was isolated separately because it was not in the breeding program, and it would only be released after the estrus period. ”

"Hey, why isolate it?" Immediately, some tourists were puzzled.

Ran into the problem of the lion house last time.

Fang Ye thought for a moment and said, "Emotionally speaking, I also hope that there will be no restrictions on them, and they will be free to give birth as they wish, but from a rational point of view, of course, it is necessary to control their reproduction.

In the zoo, animals do not have the pressure of survival in the wild, and they do not have to spend time looking for food. There are no natural predators to hunt, and if you are sick, you will be treated, and the number will continue to grow if you don't control it.

If the animals are allowed to breed at will without restrictions, it will exceed the capacity of the zoo, and there will be insufficient living area, food shortages, lions and tigers are hungry, bloodshed and fights will surge, breeders may be attacked more often, there will be too much feces to deal with in time, the park will be stinky, the probability of animal infection will increase, the keepers will be too busy and negligent, and the animals will find opportunities to flee, resulting in terrible consequences.

In general, there are several different measures to control the number of animals, such as separating male and female animals, using contraception, and euthanasia, each with its own advantages and disadvantages.

Some zoos euthanize 20 to 30 healthy animals every year, simulating the real survival of animals in the wild.

Euthanasia of animal pups born in isolation without contraception is generally to allow the parents of the animal to have the experience of breeding and raising the next generation after they have matured.

Isolation sounds better than contraception and euthanasia, but in fact, it is not, the advantage of contraception is that there is no need to isolate female animals from males in order to prevent them from becoming pregnant.

Moreover, the hormones in the birth control pill can reduce the aggression shown by males in order to compete for females, and males compete with females sometimes very fiercely, often fighting and getting injured.

However, birth control pills can also cause side effects to animals, such as large cats and canines injected with hormones, which are prone to uterine infections and tumors, and have health risks.

These measures are also designed to ensure the genetic diversity of animals and prevent them from inbreeding, which is important for the long-term survival of the species, allowing future generations to have a range of abilities that they need to survive in the wild.

The end result of this breeding management is to avoid the dangers caused by animal surplus, and to ensure that animals always have the right to breed and raise their offspring. ”

When it comes to this kind of topic, there is bound to be moral controversy.

At this time, there were a few tourists frowning, looking distressed, obviously still struggling, which method sounded like there were a lot of drawbacks, especially euthanasia, so cruel, I felt that the zoo was not as beautiful as imagined.

Fang Ye was honest with each other anyway, whether he liked it or not, and let the tourists think for themselves.

One tourist pondered: "I don't think it is possible to guarantee the quality of life of animals, so it is respectful to let animals die rather than live."

I watched a video of rescuing stray dogs before, maybe the venue and funds, can only save a hundred dogs, but I took in a thousand dogs at once, and those dogs are hungry and eat their companions, and there are many dogs infected with diseases, which is too miserable. If you have love, even if you leave a few good to take care of, isn't it better than letting these dogs hang hard, and it is more painful to live than to die. ”

Fang Ye nodded and said, "Actually, this is a positive attitude towards life. ”

When the zoo is old and weak, and there is arthritis or other diseases, and the disease is tormented and cannot be cured, it will carefully evaluate whether to euthanize or not.

However, if you are a human being, there are big ethical problems with euthanasia.

Some tourists couldn't help but ask, "Why do people have the right to decide their life and death?" Is the dog at fault? ”

Fang Ye said calmly: "You are right, there is nothing wrong with animals, no matter what they do, they act according to instinct, so we should learn and think more, know how to do it right, and be responsible for animals."

If we act only on instinct, then we are no different from animals. ”

"Quack chirp~"

Tourists next to him immediately applauded.

……

Time flies like a white horse, and a month passes in the blink of an eye!

There were no major incidents at the zoo this month, the animals were playing in the snow, the animals were busy with the snow, and some were busy breeding their offspring every day.

In the calm daily life, it is January of the new year.

After the construction of the panda pavilion was completed and the communication with the giant panda base was communicated, the rented giant panda came by plane.

The male panda is named Zhuang Zhuang, and the other female panda is named Yunduo!

At present, they are all 4 years old, and they are still a baby, and pandas will not be considered adults until they are 5 and a half years old.

To be precise, it is a sub-adult, and it is a juvenile before the age of one and a half.

Fang Ye took several employees of the zoo to the airport early to prepare for the greeting.

Everyone was smiling and excited.

Lan Carp said excitedly: "Giant panda, we are going to have giant pandas in the zoo!" ”

Fang Ye scratched her palm and said with a smile: "Look at you." ”

Lin Ying fell into a reverie, and her saliva was about to come out: "Hehe, I didn't think there would be a chance to be a giant panda veterinarian, I must touch its fur during the physical examination to see how it feels." ”

Guan Shan rubbed her hands together, her eyes burning: "Everything is ready, only the giant panda is owed!" ”

As the leader of the panda pavilion, she has also made a lot of preparations to welcome the giant pandas.

Giant pandas have special technical regulations, the feed table is extremely complex, fresh bamboo is of course the staple food, in addition to bamboo, there are bamboo shoots, apple eggs, carrots, puffed material and so on.

The food is all prepared for the pandas.

The place where the giant pandas are quarantined is directly in the back house of the Giant Panda Pavilion with special treatment.

Usually, their health is carefully tested, and they are not coming back from abroad or going abroad, so the quarantine time can be shorter, depending on the adaptation, and it can be exhibited in 7 days at the earliest.
