In the past few days, the situation of giant panda Lele and Yaya in the United States has affected the hearts of hundreds of millions of people in China.The 25 -year -old panda music died on February 1st, and then Yaya (22 years old) was reported to be extremely poor.According to the requirements of the relevant Chinese competent authorities, the China Zoo Association has arranged experts to assist in taking care of Yaya in the Memphis Zoo in the United States to do a good job of breeding, nursing, and escorting it back to China.
At the same time, some companies and individuals have expressed their willingness to adopt Yaya.In addition, many videos and photos have taken Yaya's residential venues. It seems that the environment is bad, thin bones, and dirty hair, which also reminds some people in that Yaya and Lele have been abused.When leased to the United States, he was healthy and cute, but after 20 years, Lele died, and Yaya was thin, and it was inevitable that the "mother" would have ideas.This idea is also a projection of different treatments between parent -child and adopted sons.
If you learn more about some situations, you may dispel such doubts.Not to mention the Chinese national treasure -level animal giant panda, that is, treat other animals, and the United States and West, which are in the birthplace of animal rights and welfare, will never tolerate.What's more, Lele and Yaya are star pets. Every move is under public supervision. No one dares to rush the world.
From some facts, it can also prove this.The life span of wild pandas generally does not exceed 20 years, and giant panda is generally long -lasting, between 20 and 30 years old.Lele died at the age of 25, and now Yaya is almost 23 years old, indicating that they are raising the life of giant pandas in the normal circle.Other giant pandas who are presented in the United States are the same. Lingling and Xingxing live to 20 and 27, respectively. Meixiang is 25 years old and 26 years old.
The care of Lele and Yaya is still special.According to the investigation of the China Zoo Association and the information provided by the United States, the Memphis Zoo specially opened 60 acres of bamboo forests, plant seven kinds of bamboo, and purchase bamboo from 40 censorship locations, feed the panda to pick bamboo shoots manually every day, 50 kilograms65 kg, 50 kg in spring.In addition, various panda bread, high -fiber biscuits, as well as carrots, apples, grapes and sugar cane.According to the panda, a 100 kg of adult panda eats at least 15 to 20 kg of bamboo and bamboo shoots a day, which is equivalent to one -fifth of the weight.From this perspective, Memphis Zoo is raising Lele and Yaya as a baby.
In addition, the Memphis Zoo also gives them a physical examination every year (the same is true of other plants that adopt giant pandas in the United States), and each month formulates a health assessment report based on their weight, eating volume, and feces.Multi -maintenance strategies in a timely manner, communicate with Beijing Zoo and Shanghai Zoo to improve their health management.
But why did Yaya look thin and thin?From 2021 to 2022, the China Zoo Association communicated with the Memphis Zoo, and conducted a comprehensive physical examination of Lele and Yaya for two consecutive years.The results show that the two giant pandas are lighter than the giant panda of the same age. The third moxy of the upper left of Lele is cracked. Yaya's tooth's health is good, but the hair of the whole body is rusty and dry.There are signs of infection of methamphetamine, and the color of the oral mucosa and the teeth are not abnormal.
Lele and Yaya's hair problems are mainly related to skin diseases.In 2003, Memphis Zoo found its hairy abnormality when he received Yaya for the first time.In 2006, Memphis Zoo discussed this with Beijing's giant panda experts and decided to use anti -parasitic drugs for treatment, but the hair condition after four months has not improved.
Yaya's hair color has been deteriorating, which makes animal experts think of another problem -close relative breeding leads to some physiological problems and diseases, including weak immunity.According to the Beijing Zoo's Grand Panda breeding records, Yaya's mother is Yuele and her father.Lele was not the second generation of wild pandas, but was born by the second -generation artificial insemination of Beijing Zoo.Lele's mother is Dan Dan, and Lele's father has been determined that he may be welcoming (the same panda is not the same as Yaya's father), baby, and building because of three artificial insemination records.Therefore, Yaya's mother Lele is the result of close relative breeding.Moreover, Lele has had severe skin diseases from his birth, and has not been cured.Yaya's 11 brothers and sisters all inherited the mother's skin disease because of close relatives, and they did not live in the Beijing Zoo.
These situations are enough to indicate that the real problem of Lele and Yaya is that the giant pandas are projected, and both China has this problem whether it is a circle or a wild panda.In order to avoid descendants caused by close relative breeding, China has been exploring various methods for many years to avoid it.In 2001, the National Cancer Research Institute's genome diversity laboratory helped the Chengdu panda breeding research base, established a giant panda parent -child appraisal center to use microfinee technology to record and stray the parent -child relationship of new children.Since 2005, China has also cooperated with the University of Liverpool in the United Kingdom to develop new microfinee marks, establish a panda micro -satellite database, and carry out group genetic research to prevent the giant panda from breeding.
Over the years, it has not been excluded that the breeding of close relatives in some raising bases and zoo. This is the case for Lele and Yaya, which will cause some diseases.These diseases are not onset of illness immediately, but slowly developing and developing, such as Lele and Yaya's hair problems.
For wild pandas, it is necessary to avoid close relatives.As early as 2004, the world's first giant panda discovered the land in Baoxing County, Sichuan Province. It plans to establish the first giant panda corridor in the country to allow pandas in each protected area to avoid friends and avoid close relatives.The Panda Corridor is centered on Dengchi Gougou in the National Nature Reserve of Beecibuzhai, Baoxing County, and gradually opens up the obstacles between the protected areas, allowing the corridor to connect with the Wolong Nature Reserve in Wenshui County, and Lushan County.In 700,000 to 800,000 hectares, more than 260 pandas can be accommodated.The corridor is 20 kilometers from 20 kilometers to 30 kilometers. A panda must be spent for a full week to finish. This is conducive to walking slowly to find the descendants of the people who have a high -quality birth.
All aspects of the situation show that love and protecting pandas are the same minds, and their hearts are the same, and only by following the scientific laws and methods can we effectively protect the giant pandas.

The real problem of Lele and Yaya is the panda's closure of reproduction, and there is a problem in China, whether it is in circle or wild panda.In order to avoid descendants caused by close relative breeding, China has been exploring various methods for many years to avoid it.
