Why do pandas “Big Hair” and “Two Shun” have to return home?

Can’t eat fresh bamboo panda only to return home? That’s true! Pandas must be fresh and large in amount of bamboo. The Calgary Zoo in Alberta, Canada’s largest city, sent two giant pandas, Da Mao and Dishun, back to China two years ahead of schedule after the outbreak of new crown pneumonia began, CCTV news reported.

Bamboo is a panda staple to ensure fresh enough

“Bamboo shoots are a staple food for pandas, just like our rice, fresh and large amounts of bamboo in panda breeding is the most important. One panda keeper, who did not want to be named, said it was well known that although pandas had similar digestive tracts to predators, 99 per cent of their food was bamboo. A panda eats for about 10 hours a day. As a captive panda, it is mainly a staple of low mountain Pingba bamboo, supplemented by a small amount of refined feed, fruit, vitamins and trace elements. At the same time, according to the characteristics of diet structure of different age groups of giant pandas, individual differences for reasonable matching. If there is not enough bamboo for the panda, the panda will be malnourished.

From the investigation and research, pandas are really “picking food”. Pandas eat bamboo is divided into bamboo and staple bamboo, bamboo is the daily object of the giant panda feeding, the main food bamboo, is the giant panda’s “main food.” According to a survey conducted last year by the Sichuan Forestry and Prairie Bureau, there are 216 species of bamboo in Sichuan province, but only 32 species feed for giant pandas. Among the 32 kinds of bamboo, the most popular food for giant pandas are cold arrow bamboo and lack of bamboo, accounting for about 70% of the panda’s food. The reason for this is that the two kinds of bamboo have high water content, relatively good taste, strong ability to live, wide distribution and fast growth rate, can provide adequate rations for pandas. Monitoring showed that an adult giant panda ate at least 15 to 20 kilograms of bamboo every day and night.

Why do pandas with carnivorous teeth eat bamboo alone?

Researchers at Chengdu Research Base for Giant Panda Breeding have found that giant pandas obtain energy mainly through starch, hemicellulose and pectin in bamboo. The reason for choosing bamboo, first of all in the wild, compared to other food, bamboo distribution is widely distributed, easy to obtain, with the giant panda to compete for food less competitors. Second, compared with other woody plants, bamboo contains a relatively high concentration of starch. Third, different parts of bamboo change with the four seasons and their starch content also changes. For example, during the spring and summer festivals, giant pandas prefer bamboo shoots, while in autumn, bamboo leaves are the main food and bamboo poles are the main food in winter.

Because “eat” has the panda returned home early

This is not the first time a panda has returned home early because of eating problems.

The giant panda, “Warm”, who was born at Malaysia’s National Zoo in 2015, has become an online celebrity by “returning” it early because of eating problems. “Warm” parents for China loaned to Malaysia’s two giant pandas: Xingxing and Beautiful. “Warm” love to eat fresh bamboo imported from China, the annual expenditure of more than 600,000 U.S. dollars, equivalent to more than 10,000 yuan per day. Malaysia’s National Zoo sent “warm” back to Chengdu, China, a year ahead of schedule because it couldn’t afford to “warm up” the cost of raising it.

At the Chengdu Research Base for Giant Panda Breeding, 100 adult pandas and 120 red pandas need about 15,000 kilos of bamboo shoots and 12,000 kilos of bamboo a day, but most of them are eaten by giant pandas. If the 24,000 pounds of bamboo tied into 200 pounds of 1 bundle, standardized placement, need 3 more than 5 tons of truck transport, stacked close to 200 cubic meters, plus bamboo shoots, giant panda daily rations, need at least 5 45 feet of standard containers to be loaded.

That means the pandas can fill five containers a day at the Chengdu Research Base for Giant Panda Breeding.

According to data released by the 2019 annual meeting of the Technical Committee on Giant Panda Breeding, there were 37 births and 57 survivals of 37 giant pandas worldwide in 2019, bringing the total number of captive pandas in captivity to 600, and the population of captive pandas reached a new high.

At present, based on the captive panda population, the research work on the wild release of giant pandas to promote the recovery of wild population stoking is being carried out steadily.
