Is the panda foaming at the mouth in Lanzhou Zoo sick?

On February 17 and 13, some netizens reported that the giant panda "Lan Shu" in Lanzhou Zoo was thin and foaming at the mouth, and questioned the problems in the management of giant pandas. Lanzhou Zoo is very grateful to netizens for their concern about the management of giant pandas. After receiving the response, our bureau immediately organized personnel to investigate and verify the management of panda breeding. The investigation is as follows:

First of all, about the weight of giant pandas:

Lan Shu, the giant panda, is now 23 years old (equivalent to about 70 years old for human beings), and has entered the aging stage. The weight of Lanzhou Zoo is monitored every day. On February 3, 20 17, the weight was 90.2kg (belonging to the normal weight range of adult female giant pandas). The zoo has formulated a management plan for the elderly giant pandas, and made careful arrangements in scientific feeding, medical care and disease prevention.

Second, the problem of giant pandas foaming at the mouth:

First, in spring, the quality of bamboo in the wild is relatively poor, and the food intake is relatively reduced. However, the giant panda "Lan Shu" is older, and its digestive function is declining year by year. In order to ensure its nutritional and metabolic needs, the zoo has adopted a certain number of bamboo shoots and appropriately increased the proportion of concentrated feed, which is a normal phenomenon that more saliva is produced and foam appears in the mouth during chewing concentrated feed. Secondly, with the warmer weather in spring, giant pandas are more active in outdoor sports fields, especially in estrus. When the activity increases, foam will appear in their mouths.

Zoo keepers have consulted experts from China Giant Panda Protection and Research Center many times, and it is normal for giant pandas to occasionally foam at the mouth. Veterinarians in the zoo have diagnosed that the physiological indexes of giant pandas are normal at present.
