Tiger "town" _ history magazine

The history of man �� Yuan Ching-1950s, people began to let South China Tiger breed in the city. Now the Zoo's South China Tiger, then the only descendants of the wild tigers. But the Tiger "town," stocks declining, making the South China Tiger blood difficult then to continue. In 1957, Guiyang Zoo from Guiyang Riverside Park moved to �� qianling Park, "at that time the park only ten to monkey and several Peacock". In order to increase the animal species, and expand the scale of the Zoo, the qianling Park began around the acquisition of animals within the province. At this point coincides with the wild South China tiger been wantonly killing time, people will kill the adult Tiger, the captured Tiger Baby up for sale. Thus, the "highly ornamental value" and "attractive" South China tiger was acquired qianling Park Zoo. From the local government sector learned people captured Tiger Baby, Zoo staff will soon be heading to the acquisition, "there are farmers active proffered", served as the Director of the qianling Park Zoo, Yang-chun said again. There was a peasant took two South China Tiger baby arrived from qingzhen, sold to Guiyang qianling Park Zoo. A Tiger Baby cartoon with baskets, another Tiger Baby "30 to 40 pounds," Department of the rope around his neck, "like a cat with". At that time, the South China Tiger acquisition price is extremely cheap. Under Tiger Baby size, from $ 50 to $ 100. From 1957 to 1963, qianling Park Zoo from the province of TongRen, weining, bijie, qingzhen and Changshun, total acquisition of wild South China tigers 10 only. (See history of 2010 7 monthly) ?? feeding Yang then soon-1963 entered the qianling Park. At first, he was in a zoo keeper, feeding birds, then is the horse, Antelope, forage species. About a year later, he became the cover amoyensis, carnivorous animal breeder. Yang then soon-said, the South China Tiger food by professionals with good, then handed over to the breeder's on-time delivery. "General daily to eat 10 pounds of beef, always eat large can reach 16 pounds per week can also be fed to a couple of chickens". As a breeder, Yang then soon-work mainly in the South China Tiger unattended and do a good job of cleaning barns, "one day small disinfection, sterilization," a weekly big; and at any time on the South China Tiger activities, restaurants, once the exception needs to promptly report. Breeders also have daily view South China Tiger droppings to timely detection of illness. South China Tiger is the "delicate", most easily infected with gastrointestinal diseases, if you discover that the remedy most curable. But slightly negligent, the South China Tiger will suffer from growth on my face, cancer and other diseases, such as South China Tiger is fatal. Music Center in 1974 from Guizhou College of agriculture are deployed to the qianling Park Zoo as "Tiger doctor". He had looked at a South China Tiger because of mesothelial Sarcoma died in the Zoo. After more than 30 years, his days are still fresh in my memory �� 1979 2 September. 1965-born "in fact" farming has 17 Tiger Baby, is artificial feeding of South China Tiger "in the hero", also because of illness and death. Le Cheng said, early 1980s, he discovered the "fact" and pull out the manure becomes thin, so it took some intestinal antibiotics for treatment are not effective. Later, the "fact" is loss of appetite, apathetic, and love. The month of November 1980, "in fact" abdominal swelling gradually, "and often drastic jitter, presumably because of the pain bar". Happy median tried where the "fact", the end result of medical conditions is limited. Of 15 December 1980, it died due to liver cancer at the Zoo. (See history of 2010 7 monthly) �� reproduction at the same time, the qianling Park to begin artificial breeding attempt of South China Tiger. Le Cheng said, in the feeding process, when South China tigers grow to 2 years old, they began to select Tiger. General selection body is long, big, powerful, can eat and restless, no disease of Tiger Tiger do. As the saying goes, "a mountain brook no second Tiger". Selected male and female Tiger, you want to be kept in the neighbouring respectively of the cage so that two Tiger familiarization, mating with cage without hostile to each other. Tiger tamed by hand needed to close the Tiger and the keepers of the "relationship". When the South China Tiger nose against the breeder when making noise that he has obtained the trust of the Tiger. Yang then soon-said that the propagation in the biggest trouble is two South China tigers season. They came up with a method of "Earth", find some sprouting in wheat, mixed into the season later of a tiger in the feeding of animal feed, you can reach the estrus stimulating role. In captivity, female South China tiger in 3 and half years to reach sexual maturity, the 4-year-old male, until 14 years old are the breeding period, "but in 11-year-old former breeding of pregnancy rates are relatively high," Le Cheng said. In fact, the temperament after childbirth is extremely violent, suspicious. "At least half a month can't let strangers near Tiger Baby, even after the delivery of professional keepers of food must also be leave promptly. Otherwise, in fact, becomes unrest, mouth with Tiger Baby walking, very easily lead to Tiger baby died. "Yang-chun said again, for the above reasons, the qianling Park Zoo has repeatedly occur Tiger baby died. (See history of 2010 7 monthly) �� fall 1963-1979, qianling Park Zoo total propagation of South China Tiger 24 61 fetal, farrowing, only survive more than 30 only. Artificial breeding huchenggong South, all provinces have come to the Zoo qianling Park ask for or Exchange the South China Tiger. As early as 1959, qianling Park had a wild South China tigers sent to Beijing Zoo, the Tiger is the 1957 purchased from ren. In the early days, qianling Park Zoo for a total of five wild South China tigers sent to other provinces, of which only the Vixen, 3 2 male Tiger. This Park, with only 1 public 4 female 5 just South China Tiger as a tiger. In 1974, and in fact, only 2 were sent to other provinces. The only public Tiger is acquired from the qingzhen, 1958, so called "qingzhen Tiger". Qianling Park Zoo artificial reproduction of all South China Tiger belong to its descendants. In 1963 and 1964, "Tiger" qingzhen with two mated females, two years of success with 8 Tiger baby. One was called "big tiger". In the absence of Tiger kinds of situations, from 1972 to 1976, with the qianling Park Zoo"The Tiger" the Grand Duke and his brothers two sister mating, 5 years production of pups surviving 21 only. During this period, the qianling Park South China tigers still continuously "support" at the Zoo home, or even sent to Sudan. 70s became South China Tiger breeding at its peak. Yang then soon recalled that at the time of the qianling Park three mile Bay Hostel reception to the news every day, two to three home field Zoo came to discuss the South China tiger trade issues. Each of the selling price of the South China Tiger only about 2000-3000 Yuan, by contrast, the Amur tiger of prices to double, each only 5000 to 6000 Yuan. At that time, the South China Tiger and undervalued, Yang then soon-recalls, qianling Park Zoo had two South China tigers sent to Beijing Zoo, but only in exchange for a zebra of pups. Tiger species loss caused trouble afoot. "The consequences of inbreeding is South China tiger populations in decline". In Mr then soon-memory, the first batch of artificial reproduction of South China Tiger pomp, well-built, restless, food intake, later propagation of instalments are sized smaller, mostly with concave dorsal, short foot deformity such as, but not overly active, eating poorly, breeding ability decreases. Artificial breeding of South China Tiger has gradually lost the "King of the beasts" treasures. In order to solve the problem of propagation of South China Tiger, 1979, the Music Center with the "dual mating" method, the two male Tiger mating with a fact. Spent 6 days in and two male Tiger after mating 60 times, respectively, in fact, was finally pregnant and 102 days after successful delivery of three cubs. This is the qianling Park Zoo last successfully bred South China Tiger. Be used as a "dual mating" two male Tiger respectively known as the "young Tiger" and "big tiger", in fact, is in fact the "second." The "young Tiger" is the "Grand Duke of the Tiger" and "second fact," the mating in 1973. To 1983, qianling Park Zoo only remaining 6 only South China Tiger. 1992 transfer out of the two, the remaining 4 only, and will soon have died because of old age. A wild South China Tiger as a source for artificial breeding of this branch of the South China Tiger pedigree, and finally in the mid-1990s, the country's first artificial breeding base for South China Tiger qianling Park. �� This document from the history of the 2010 �� 7 monthly qianling Park in 1963, Guiyang, Guizhou Ling Park was the first in the world for the first time through the artificial breeding success in South China Tiger to 1979 total propagation 24 tires, farrowing only 30 61, survival, only here qianling Park a total output of 33 only South China Tiger (including wild tiger 6 only) to Beijing, Shanghai, Dalian, Anshan, Harbin, Chongqing, Anhui, 14 Zoo, and the South China Tiger far travelled to North Korea, covered by vast oceans, Sudan. To the 1980s, qianling Park South China Tiger then no propagation, finally a South China tiger died because of old. At present, China's more than most of the South China Tiger Zoo is the qianling Park South China Tiger. In 1984, the national society for the South China Tiger decision in Guiyang, Chongqing, Shanghai, the establishment of the South China Tiger breeding population base. Qianling Park does not seek to specific support. South China Tiger pedigree China South China Tiger on artificial reproduction began in the 1960s, now the South China Tiger Zoo, all year 6 Tiger's fourth-, fifth-generation offspring. Today, the South China Tiger captivity inbreeding coefficients highest reached 0.4921. If the inbreeding coefficient higher than 0.25, mated belonging to members of their immediate families, that is, the "parent" and "child" and "brother" and "sisters" mated. Inbreeding coefficient reaches 0.4921, can be said to be "self mating" results. Wild South China tigers average growth two or three at a time can head the Jaguars. Because of inbreeding, artificial birth rate captive South China Tiger year, only 17 per cent to 49 per cent survival rate is not even seen a tiger with all production several fetal mortality. Even if you were lucky enough to escape the "natural selection" surviving South China tigers, in behavior is also an amazing variation. Many of the South China tiger even animal instincts are completely lost, on specific completely uninterested even fatal attack, a Zoo has a male tiger killed vixen tragedies. 1991 ~ 1996, Chongqing Zoo on 6 only male South China Tiger carried out 10 times artificial semen, sperm quality inspection results: azoospermia 1 cases, few sperm 3 cases, more than 5 million sperm density in the Pml ~ 1500 million Pml 6 cases between, all dead spermatozoa of seven. Only two cases of sperm vitality, sperm in 9 cases, contains 10% ~ 80% of varying degrees of tail or pointed immature sperm abnormalities. In this context, the establishment of the South China Tiger pedigree becomes urgent. 1995 started establishing a genealogy of South China Tiger. Now, pedigree already documented the 1950-present nearly 400 only captive South China Tiger's detailed phylogenetic relationships and rearing conditions, the South China Tiger for captive birth provides crucial data support.
