The students in the class have come together!

One by one, they surrounded the narrator, but kept some distance, excited and shy and nervous, similar to the feeling of a pure teenager seeing a small movie for the first time.

It's exciting!

Liu Wei was speechless for a while: "Turtle turtle!" ”

Wu Jiancong's eyes widened: "Turtle turtle, panda feces!" ”

Yang Yue ate and smiled, looked around, and her face was a little red: "Which of you is going to smell it?" ”

Growing up so big, ethics and morality are formed, and feces are associated with dirt and privacy in the impression of everyone.

In front of the public, seeing a piece of feces held in the hands of people so generously, even if they knew that this was panda feces, which was used for popular science, and was displayed in front of them, they still couldn't let go of their hands and feet.

The narrator looked at everyone's reactions: "Actually, it doesn't stink, but it's a little fragrant, don't you really want to smell it?" ”

Gao Kaijin's eyes were disgusted, and he looked a little yearning: "Really fake? It can't lie to us, right? ”

Classmates, you push me, I push you, whispering: "Eh, don't you want to smell it?" ”

"Smell it!"

It's not just that the taste may not be wonderful, it's more of a shame!

A child who looked like he was elementary school age didn't have so many scruples, and raised his hand and said, "I want to smell it!" ”

The narrator smiled: "Okay! ”

Reach over and the child brings his face closer!

I closed my eyes, my nose twitched, and I sniffed seriously.

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

Everyone was a little embarrassed, the children were so generous, they were shy.

Letting go of his shame, Wu Jiancong coughed twice, raised his hand and said, "I want to smell it too!" ”

Wu Jiancong's family is in Chengdu, and pandas are also proud of their hometown!

I've been to the zoo to see pandas before, but I've never smelled panda feces.

The classmates clapped: "Brother Cong is amazing!" ”

"I'd like to make you a big pioneer of smelling!"

Liu Wei smiled: "Brother, I'll take a photo for you!" ”

Wu Jiancong didn't care about everyone's ridicule, took two steps forward, and observed carefully.

The panda dung in the narrator's hand is cyan, about the same size as a cigarette box!

The shape is like an oval shape, with a slightly rounded end and a little pointed at the other.

Inside, you can also see some small and large broken leaves, and the overall appearance looks like a blue ball tied up with a bundle of chopped bamboo leaves, and it seems to be a little wet.

Looks like it should have been freshly baked today!

He lowered his head and fanned his hand.

The nose sniffed carefully, and there was really a faint fragrance!

It's like opening a pot of tea and smelling it inside.

Everyone looked at Wu Jiancong curiously, wanting to see what his reaction was!

Wu Jiancong's eyes lit up: "Eh, this taste is really good!" Smell it! ”

The students came forward to smell it, and it was a very new experience for them.

They all laughed, and some even showed intoxicated expressions: "It's a bit like the taste of tea!" ”

"I feel like it smells of Chinese medicine!"

"Why do I feel like it's a cookie?"

Gao Kaijin thoughtfully: "I don't know if I can use it to make tea!" ”

Liu Wei shuddered: ", brother, you have a bit of a heavy taste!" ”

The students sniffed the poop one by one, and the narrator watched the reaction of the crowd and explained with a smile: "Isn't it beautiful poop?" You should be able to see the bamboo leaves inside!

The bamboo leaves eaten by the panda will show such a bright green color in its feces, so the panda is also called Qingtuan! There are also some thin rods, this one is undigested bamboo fiber.

Because the panda's digestion ability of bamboo is relatively poor, about only about 20%, so what is basically eaten is what is pulled out. ”

"Damn, isn't this the same as us humans eating enoki mushrooms?"

"Crooked, your statement is a bit disgusting!"

Panda feces are still quite cute, but human feces are a bit ......

Someone asked curiously: "Since pandas can't digest bamboo, why do they eat bamboo?" ”

The narrator said, "This is going to start from a long time ago...... Faced with changes in the environment, as well as the pressure of competition, Panda chose bamboo as food, which is more easily available! Because the digestion efficiency is not high, the panda has developed the habit of eating fast and pulling quickly, and eating more Dora.

This group is from our female panda Yunduo, and we will throw more than 20 kilograms of bamboo into it every day, and the other male giant panda is strong, and we will throw 30 kilograms of bamboo every day.

There are up to a dozen bowel movements a day, and about 10 kilograms of feces can be discharged. ”

"Wow!" There was an exclamation of amazement.

"By the way, when the clouds sleep, they especially like to sleep surrounded by feces, and there is a circle of poop all around, as if this can give it some security."

"Haha!"

"Is it so fun?"

It's funny to think about.

The narrator continued: "In fact, panda feces contain many secrets! You can tell what the panda eats by the color of the feces.

The main component of this piece of feces is bamboo leaves, which are rich in green, and if the green is lighter, then the bamboo pole is eaten. If it's earthy yellow, then it's bamboo shoots. Eating the feces excreted from bamboo shoots will taste more stinky!

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

For example, if you look at the edge of this bamboo, it is very clearly cut, indicating that the panda's teeth are very good.

The size of this feces is just right, indicating that the panda's intestinal function is very good, and the poop is very strong, if the intestinal function is weak and the feces cannot be clamped, the feces will become relatively coarse.

If the feces are sticky, it may be that the supply of bamboo is insufficient, and in this case, the panda will curl up on its side and lie motionless on the ground, and have no interest in feeding. ”

"Wow!"

The students were dumbfounded, but they also felt very interesting, and listened to them with relish.

I used to just know that pandas were cute, but I didn't expect there to be so many interesting stories in the feces.

The narrator smiled: "Including the identification of giant pandas in the wild, feces can also play a great role!"

In the natural environment, giant pandas are good at climbing, have a wide range of activities, and hide in the mountains, which are not easy to photograph with infrared cameras.

For example, tigers and leopards have unique lines and spots on their bodies, which can be identified from this aspect, but pandas have black and white faces, which are difficult to identify.

When the panda's feces are excreted from the body, the outside is wrapped around some cells shed on the surface of the intestine, and the DNA of the giant panda can be extracted from the inside to accurately identify the individual. ”
