Poetry about pandas eating bamboo shoots 1 Poems about pandas eating bamboo leaves
Giant pandas are carnivores, but 99% of their food ingredients are more than 20 kinds of bamboo plants that grow in high mountains and deep valleys.
With the change of seasons, the species of bamboo and the parts of bamboo eaten by giant pandas are also different. My favorite is bamboo shoots. From spring to summer, they like to eat several bamboos of Phyllostachys, and bamboo shoots of Bambusa, Fargesia, Fargesia and Fargesia. Bamboo shoot is a new type of bamboo plant without branches and leaves, which grows from underground stems of bamboo. Its tissue is tender and its water content is high. Its nutritional components are crude fat 1.27%, crude fiber 33.62%, crude protein 10.32% and total sugar 26. 15%.
Bamboo shoots are tender and juicy, delicious, easy to digest and absorb, and are delicious food for giant pandas. Every year from spring to autumn, in order to eat different kinds of bamboo shoots at different altitudes, giant pandas migrate from Zhongshan to the mountains for food, which is called "catching bamboo shoots"
From the whole Zhu Zhi's point of view, from the lower part to the upper part of bamboo plants, the nutrient content gradually increases. Take the cold arrow bamboo as an example, the crude fat content of bamboo stems is 0.59%, bamboo branches are 3.37%, crude protein bamboo stems are 4.20%, bamboo leaves are 19.44%, crude fiber bamboo stems are 46.66%, and bamboo leaves are 24.27%.
It can be seen that although giant pandas like to eat bamboo shoots, they often feed on the bamboo leaves and upper-middle bamboo stems of annual young bamboo, which is very reasonable. The national treasure giant panda is a carnivore, but more than 90% of its nutrition comes from bamboo.
How do giant pandas digest high-fiber bamboo? This has always been a mystery. Recently, it was reported from Chengdu Giant Panda Research Base that after five years' efforts, scientists and technicians found ciliates in the giant panda's stomach for the first time, which will have a far-reaching impact on the digestive physiology research of giant pandas.
The carnivorous giant panda has the digestive tract of a typical carnivore: the intestine is short, there is no stomach, and there is no developed cecum. So how giant pandas digest bamboo is a mystery that countless people want to solve.
In the past five years, researcher Fei from Chengdu Zoo and Professor Yang Guangyou from Sichuan Agricultural University have worked closely together and finally found a large number of ciliates in the giant panda's stomach. According to reports, ciliates generally exist in the digestive tract of herbivores, and their total biomass accounts for about 50% of the total microbial population in the whole digestive tract, which plays an important role in the digestion and utilization of plant foods.
In the long process of evolution, carnivorous giant pandas changed their eating habits, mainly to adapt to the living environment. The changes of animal's diet and nutrition often affect the related organs of food digestion and absorption first, and finally affect the whole body of animals.
It is estimated that some changes have taken place in the digestive physiology of giant pandas, but what changes have taken place in the end is a subject that needs further study. Giant pandas are carnivores, but 99% of their food ingredients are more than 20 kinds of bamboo plants that grow in high mountains and deep valleys.
With the change of seasons, the species of bamboo and the parts of bamboo eaten by giant pandas are also different. My favorite is bamboo shoots.

It can be seen that although giant pandas like to eat bamboo shoots, they often feed on the bamboo leaves and upper-middle bamboo stems of annual young bamboo, which is very reasonable. Giant pandas living in the wild occasionally eat other plants, such as wheat without awn, corn, equisetum, green grass, polyporus umbellatus (xùn), wild angelica, notopterygium root, young fir bark and so on.
Even uncharacteristically, picking up dead animals or catching smaller animals for food. Giant pandas love meat, especially mutton.
Giant pandas are so powerful that they are not afraid of leopards. If they join hands, giant pandas usually win.
2. What do pandas eat? Pandas eat bamboo shoots
What do giant pandas eat to gain weight most easily? After studying the effects of different bamboo foods on the health and metabolism of giant pandas, researchers recently answered this interesting question. Related research results have been published in the scientific report published in June 2007.
Bamboo is the main food for giant pandas, but giant pandas will eat a lot of bamboo stems, leaves and bamboo shoots in a certain period of time. The nutritional components of three kinds of bamboo foods are quite different. What specific effects will they have on the health and metabolism of giant pandas? Wang Hairui, a researcher at Chengdu Giant Panda Research Base, took the lead in studying this problem in the world.
Bamboo shoots are panda's favorite food. Studies have shown that giant pandas gain weight obviously after eating a lot of bamboo shoots. Blood analysis showed that the high protein level in bamboo shoots led to the increase of serum urea nitrogen level and protein metabolism related indexes of giant pandas.
Due to the relatively high fat content of bamboo leaves, the blood lipid level of giant pandas increased significantly after eating a lot. However, the results of nutrient digestion test show that the digestibility of fat in bamboo leaves is very low and the efficiency of fat digestion and utilization is also low.
Among the above three kinds of bamboo foods, the energy level of giant pandas from bamboo stems is the highest, but the weight of giant pandas shows negative growth during eating bamboo stems. It is found that the fiber content of bamboo poles is too high, and the process of digesting fiber requires more energy, which makes the body in a negative energy balance state, leading to the negative weight growth of giant pandas when eating bamboo poles.
Studies have shown that among the three kinds of bamboo foods, giant pandas eat bamboo shoots most easily to gain weight. But giant pandas can't be partial eclipse, because the diversity of bamboo food is very important to the health and metabolism of giant pandas. No matter what kind of single bamboo food, giant pandas will have adverse effects on their health after eating it in large quantities.
The researchers said that this result will provide scientific data support for giant panda breeding management and provide theoretical basis for improving the health level of giant pandas. (Source | China Youth Daily)
Why do pandas eat bamboo shoots?
The ancestors of giant pandas are carnivores. How can they change from carnivores to vegetarians now? This is related to the change of their living environment.
After the glacier attack, the giant pandas left in Sichuan and Gansu can only survive by gradually changing their eating habits. As a result of the panda's long-term adaptation to the environment, it changed from eating meat to eating bamboo, and its molars became particularly wide, suitable for grinding bamboo fiber. Giant pandas like to eat cold arrow bamboo, ink bamboo, water bamboo, especially bamboo shoots.
I go somewhere to eat bamboo shoots on time every year. Giant pandas eat a lot, eating about 20 kilograms of tender bamboo every day and absorbing nutrients from a lot of fiber.
Because it digests a lot of fiber and lignin every day, it especially likes drinking water. Of course, pandas occasionally eat other small animals. If it sees a bamboo rat, slap it to death and have a good meal.
Panda's usual life, except eating, is sleeping, and when he wakes up, he begins to eat again. Sometimes I go to the stream for a drink.
The giant pandas in the world are only produced in China, and only distributed in the mountainous areas of Sichuan and Shaanxi provinces in China, so they are extremely precious and known as "national treasures". Because bamboo has ups and downs, it will only bloom once every 50 to 60 years, and then it will die. At this time, the giant panda is short of food and its life is threatened.
At present, China has established a giant panda reserve, organized large-scale rescue activities for giant pandas, and carried out artificial breeding to make this "national treasure" last forever.
4. Some poems about pandas
I have never studied hard for dark circles.
Wash inkstone and check ink
Sigh, sword, bamboo, white flowers fly
Pity fetters the deep courtyard
The panda flute blows on both sides,
Looking for bamboo shoots and poles day and night,
Put the pen in your mouth and dip it in ink.
To commemorate the reunion of the motherland.
Bamboo forest baby to green bamboo,
The velvet body has been walking for a hundred years.
Time flies, the country is not round,
The ship sailed across the channel to send peace.
The bear growled, the forest trembled, the sky roared,
The leaves of the cat dance fell half a foot.
Sincerely welcome the world,
It is true that the country is rich.
I'm glad that Beijing welcomes the Olympic Games.
Love and hate quotations: incense chips.
Fulu visited the bear,
Kittens are sent to spring and autumn.

6. What do pandas eat besides bamboo leaves, bamboo shoots and bamboo?
Panda's food is mainly sword bamboo. The characteristic of bamboo is that it can be lush all year round, and the nutritional components of each part are basically the same. They eat bamboo hearts and bamboo shoots, and sometimes they eat bamboo leaves. But the panda's intestines are very short, and there are no bacteria that ferment cellulose. Pandas can only absorb 17% of the bamboo they eat, while geese's food passes through the digestive tract quickly, with a utilization rate of 30%. This makes pandas eat more than 10 hours a day. Because pandas eat many kinds of bamboo, and there are many kinds of bamboo in their habitat. There is no conclusive research evidence that giant pandas will starve to death and endanger their lives because of the periodic flowering and death of bamboo. It is the artificial development of the habitat that makes the panda's habitat shrink and it is impossible to find a suitable bamboo forest. In ancient times, there were many records about pandas eating iron, so they were named "iron eaters", which mostly happened when pandas broke into people's homes. Their jaws are strong enough to bite iron pots, but why they eat these things is unknown.
