Mammalia, artiodactyla, cervidae, cervus, which is known as "the deer of clubs" because of the many organized white spots on both sides of their backs and under their sides. There are currently four sub-species in china, the north-east asian (c. N. Mantchuricus), the south asian (c. N. Pseudaxis), the sichuanicus (c. N. Sichuancus) and the taiwan asian (c. N. Taiouanus). At the national level, priority is given to the protection of animals, and the world conservation union (iucn) in 2015 has listed melon deer as the red list of endangered species [1]。
Plum deer is a small and medium deer. 140-170 cm long, shoulder 85-100 cm tall, tail 12-13 cm long, weight 100-150 kg. The head is long, the nose is naked, the eyes are wide and round, the lower glands are fractured, the tears are visible, the ears are long and straight, the neck minister, the limbs are long, the female has no horns, the male has horns, the young antler is called a deer before the bone is fully boned, the adult antlers are four ounces, the horns are 30-66 cm. Black on the back, white on the abdomen, with sharp white plum spots, white on the buttocks, hair changes with season and hair on the neck。
A mellow deer living in a vast mix of forested mountains, forest margins and grasslands is not in a dense forest or bush, thus facilitating rapid run-off. In the daytime, they prefer to dwell on the slopes of the sun, and the grass is thicker and similar in colour, so that they can detect the enemy; in the middle of the slopes or in the upper part of them, they are still dominated by the slopes of the sun, while the grass is relatively small. They are clustered, with different seasonal clusters, which tend to be more clustered during the winter season, in which the head of the deer affects the movement of the whole herd, which runs in the direction and route of the deer when fleeing harm. The most appropriate living temperature is 8-25°c, while high temperatures prefer to hide in a deer's room or under a shade, even at 5-10°c, which is likely to move freely, without affecting the ability to collect and the amount of food. Agile, alert, timid and timid, but highly developed and sensitive to smell, hearing, vision, and when sudden sounds or accidents occur, the phenomenon of “blasting” is common。
In february-july, the deer gets warmer. The male plum deer competes for the right to mate by fighting for the right to mating. The deer can have multiple inclements, usually five days, with a pregnancy of about 230 days, usually having one child per child, with a high rate of survival and growth, with a growth rate of up to 10 kg in four months, with 1 and a half years of sexual maturity and 20 years of life。
They are mainly located in north-eastern asian countries such as china, japan and russia. Much of the wild plum deer population has been extinct as a result of excessive hunting, habitat destruction, natural enemy hazards, stock segregation and inter-species competition. Wild plums are already highly endangered animals in china, with a total of less than 1,000. The north asian and shansian species have been extinct, and there are about 400 south asian species along the borders of anhui, zhejiang and jiangxi, and less than 100 in guangxi. Sichuan asians have about 500 in the north of sichuan and south of gansu. The north-east asian species may have been extinct, although the stocks that have been domesticated were later razed and released, and there are now about 200. After the extinction of taiwan’s asian species, since 1969, wild plum deer has gradually disappeared throughout taiwan, and has succeeded in artificial reproduction。
We are one of the world's oldest reindeer farmers, one of the world's three largest reindeer farmers (new zealand, china, russia), and new zealand is the world's largest reindeer farmer. According to the latest statistics of the deer industry branch of the chinese livestock association, the stock of barley deer in china is about 1 million, and a melon can produce 600-700 g deer a year, at a price of between 50 and 200 yuan/g, and a melon deer can earn between 3,000 and 14,000 yuan a year. According to china's agricultural yearbook 2017, the total production of deer slurry was 79 t in 2015 and 77 t in 2016, with new zealand being the largest exporter of deer slurry, and south korea the largest importer and consumer. The stellar deer is of high pharmaceutical value and has been widely used in health care. Deer meat is known for its high proteins, low fats, low cholesterols, nutrients and tastes, and is highly popular with consumers, and it's known as "the dragons in the sky, under the ground."。
In order to protect the plum deer stock, the plum deer reserve field has proposed a conservation management response: (1), greater awareness and efforts; (2) administration and compensation in accordance with the law; (3) protection of mountains and expansion of stocks; (4) timely feeding to ensure food availability; and (5) mapping of homes and conducting surveys [3]。
The hunan teacher university's plant and plant sample house has a stag specimen from the long sand zoo for an unknown period of time, which was made by wang yu, a technician at hunan university。
