The results showed that the behavior could be divided into 5 major types: moving, resting, sleeping, eating and other behaviors (including drinking, urinating, grooming, playing, standing). Of all behavioral models, sleeping and moving behaviors alone accounted for 75.18% and were two major behavioral models of all behaviors. Resting, eating and other behaviors accounted for 24.82%. Apart from eating, one male and two female individuals have similar peak periods of 4 major behaviors (one peak period in the daytime, and one peak period at night), similar to that of wild Amur tiger. However, one female individual have two clear peak periods at night.展开更多

At present, four survival subspecies are endangered in China. Tiger has decreased greatly in number, and its distribution has limited to some areas. The published papers on morphology and anatomy were relatively few, while much work has been done on physiology and biochemistry of captive tigers. The author pointed out a few further research fields. The studies of chromosomes, gene, cloning and establishment of gene bank should be mostly focusing fields. Feeding and breeding techniques must be improved and reinforced.展开更多

This paper dedicated distribution and quantity of wild South-China tiger, and also introduced distribution, quantity and pedigree of captive South-China tiger. In the middle of this century, about several thousands South-China tiger distributed in following provinces, such as Hunan, Jiangxi, Guizhou, Fujian, Guangdong, Guangxi, Zhejiang, Hubei, Sichuan, Henan, Shanxi, Shanxi, Gansu. etc. Until now, there are only about 20–30 wild South-China tigers distributing in the provinces of Guangdong, Fujian, Jiangxi, and Hunan, Sichuan, and 50 captive South-China tiger are raised in zoos of China.展开更多

The population in China decreased from 120 in mid 1970's to less than 20 now. Hengdaohezi Felidae BreedingCenter was established in Heilongjiang province in 1986. The Sibcrian tigers were fed artiticially and were trained to reintroduce primarily. The population increased from eight to scventy by hard work for about ten years. In the meantime, the researchers have done much research work on physiology, biochcmistry, brecding, behavior, disease prevention and so on,they have got much valuable infonnation of tigcr population. In January, 1996, 'Siberian Tiger Park' was built on the eastside of The Sun Island in Harbin. The China's unique and the world's largest Siberian Tiger groups are being domesticatedhere. Because of the change of the living condition, the focal point of th1c tiger pop[llatiol1 l11al1ageme1lt is now to reintroducethe tigers. So, the tigers are being trained to lcarn how to prey in the wild, how to adapt the bad nature environment and increase the ability of disease prevention.
