[Explanation] The staff of Guangzhou Chimelong Wildlife World have to "do housekeeping" every morning, and many of their service objects are national treasure animals.
However, in addition to keeping the animals' living environment clean and tidy, there are still many "babies" to be collected, and the staff are also dubbed "animal feces".
[Explanation] According to experts, an adult elephant can eat 400 pounds of food a day, but it can also excrete 300 pounds of feces. The amount of "baba" produced by a group of elephants every day is quite considerable, which is also not small in zoo management. burden.
But in Cui Zhengan's eyes, these are "baby".
He is familiar with pandas, South China tigers, and koalas' "Baba".

This one is the feces of giant pandas. The feces of giant pandas have a lot of fiber and look like some scum.
In fact, these are some very long fibers of bamboo, and some fresh panda feces, it will also have a fragrance of bamboo.
This is the feces of elephants. Elephants produce a lot of feces every day. The characteristics of its feces are similar to those of giant pandas, which are high in fiber.
This one is tiger feces. This tiger feces can also be said to be the best in feces, because it contains high nitrogen content. Carnivores themselves have high protein, fat and other nutrients. In addition to the peculiar smell of tigers, other odors are also quite unfriendly, and most people cannot accept it.
As a fertilizer, it contains high nitrogen elements, which are essential elements for plant growth.
[Explanation] The use of animal feces to ferment into plant fertilizers turns waste into treasures. This is the zoo's "Baba Cultivation Program".
However, it takes a lot of effort. From the collection of feces to the layer-by-layer control of compost fermentation, the whole process requires the efforts of the staff and the support of scientific and technological strength.

It is difficult to ferment some animal feces, because some organic components in it are very low, or its harmful components are very high. At this time, we need to adjust some of the microorganisms in it, and we will add some extra Oxygen bacteria, for example, will add some lactic acid bacteria to it to create an acidic environment, so that harmful microorganisms can be effectively inhibited.
[Explanation] It takes about 20 days in summer and 30 to 45 days in winter. After the microbial content was finally tested by the staff to pass the test, "Baba" finally became an organic fertilizer.
The animal "baba" expert uses them to fertilize the park's bamboo and eucalyptus forests, the favorite food of giant pandas and koalas.
In the end, "Baba" completed the green-treated "Baba Health Journey", realizing the value of grass-fed growth of the back-feeding herbivores.
