All the students in the class came together!

One by one, they surrounded the commentators, but kept some distance. They were excited, shy and nervous, which was similar to the feeling of pure teenagers when they saw a small film for the first time.

Very exciting!

Liu Wei was speechless for a moment: "turtle!"

Wu jiancong stared: "turtle, panda dung!"

Yang Yue giggled and looked around. Her face was a little red: "who of you is going to smell it?"

Growing so big, ethics and morality take shape. Feces are associated with dirt and privacy in people''s impression.

In public, I saw a lump of dung held in my hand by such a generous person. Even if I knew it was panda dung, which was used for science popularization, it was still a little difficult to show it in front of me.

The commentator looked at the reaction of the crowd: "actually, it doesn''t smell, but it smells a little fragrant. Don''t you really want to smell it?"

Gao Kaijin''s eyes were disgusted and looked forward to: "true or false? Can''t you lie to us? "

Students, you push me, I push you, whisper: "Hey, don''t you want to smell it?"

"Smell it!"

Not only do you think the taste may not be very beautiful, but also shame!

A child of primary school age did not have so many scruples. He raised his hand and said, "I want to smell it!"

The commentator smiled and said, "OK!"

Put your hand over, children, close your face!

Close your eyes, twitch your nose and smell it seriously.

The child opened his eyes and looked surprised: "Well! There is a smell of leaves! "

People are a little embarrassed. The children are so generous. They are shy.

Putting down his shame, Wu jiancong coughed twice, raised his hand and said, "I also want to smell it!"

Wu jiancong''s family is in Chengdu. Pandas are also proud of their hometown!

I''ve seen pandas in the zoo before, but I really haven''t smelled panda dung.

The classmate quack quack clapped: "brother Cong is powerful!"

"I would like to make you a pioneer in smelling shit!"

Liu Wei smiled: "brother, I''ll take a picture for you!"

Wu jiancong did not mind everyone''s ridicule. He took two steps forward and observed carefully.

The panda dung held by the commentator is blue, about the size of a cigarette box!

The shape is like an ellipse, with a dot at one end and a tip at the other.

Inside, you can also see some large or small broken leaves. On the whole, it looks like a blue ball tied up with a bundle of chopped bamboo leaves. It seems a little wet.

It looks like it should be fresh today!

Lower your head and fan your hand.

The nose sniffs carefully. It really has a faint fragrance!

I feel the same when I open a can of tea and smell it.

Everyone looked at Wu jiancong curiously to see his reaction!

Wu jiancong''s eyes brightened: "ah, the taste is really good! You smell it! "

The students came forward one after another and smelled it. It was a very fresh experience for them.

One after another laughed, and even someone showed an intoxicated expression: "it''s a bit like the taste of tea!"

"I think it smells of traditional Chinese medicine!"

"Why do I feel like cookies?"

Gao Kaijin thought: "I don''t know if it can be used to make tea!"

Liu Wei trembled: "lying in the trough, brother, you have a little heavy taste!"

The students smelled the poop one by one. The commentator looked at the reaction of the people, smiled and explained, "is it a beautiful poop? You should be able to see the bamboo leaves inside!

When pandas eat bamboo leaves, their feces will show such a bright green color, so pandas are also called qingtuan! There are also some thin rods. This is undigested bamboo fiber.

Because pandas have poor digestion of bamboo, only about 20%, so what they basically eat and what they pull out. "

"Lying trough, isn''t it the same as we humans eat Flammulina velutipes?"

"Crooked day, your statement is a little disgusting!"

Panda feces are still cute, but human feces are a little

Someone asked curiously, "since pandas can''t digest bamboo, why eat bamboo?"

The commentator said: "this has to start from a long time ago... In the face of environmental changes and the pressure of competition, pandas choose more accessible bamboo as food! Because the digestion efficiency is not high, pandas have developed the habit of eating and pulling quickly and eating and pulling more.

This green group is from our female panda cloud. We throw more than 20 kilograms of bamboo to it every day. The other male giant panda is strong and strong. We throw 30 kilograms of bamboo to it every day.

Defecate more than ten times a day, and can excrete about ten kilograms of feces. "

"Wow!" The crowd exclaimed.

"By the way, when the clouds sleep, they especially like to sleep surrounded by feces. The surrounding area is full of shit. It seems that this can bring it some sense of security."

"Ha ha!"

"Is it so fun?"

It''s interesting to think about this picture.

The commentator continued, "in fact, there are many secrets in Panda feces! What pandas eat can be judged by the color of feces.

This piece of excrement is mainly composed of bamboo leaves, which is rich in green. If the green is light, what you eat is bamboo poles. If it''s earthy yellow, it''s bamboo shoots. The feces discharged from eating bamboo shoots will stink!

Our keepers collect the feces of pandas every day, and their health can be judged by their feces.

For example, looking at the edge of the bamboo, the cutting is very clear, which shows that the panda''s teeth are very good.

The size of the feces is just right, indicating that the panda''s intestinal function is very good and the feces are very strong. If the intestinal function is weak and can''t be clamped, the feces will become thicker.

If the feces are sticky, it means that there may be a shortage of bamboo. In this case, the panda will curl up on its side and lie motionless on the ground, and is not interested in feeding. "

"Wow!"

The students were stunned and felt very interesting. They listened with interest one by one.

I just knew that pandas were cute before. I didn''t expect there were so many interesting stories in feces.

The commentator smiled and said, "including the identification of wild giant pandas, feces can also play a great role!

In the natural environment, giant pandas are good at climbing and have a wide range of activities. They hide in the mountains and are difficult to be photographed by infrared cameras.

Animals such as tigers and leopards have unique lines and spots, which can be identified in this regard, but pandas have black-and-white facial makeup, which is difficult to identify.

When the panda''s feces are excreted from the body, they are wrapped with some cells falling off the intestinal surface, so the DNA of the giant panda can be extracted from it and the individual can be accurately identified. "
