Zhangjiajie Dagu meat is delicate, delicious, and unique in flavor. Euphorbia is soft, with high protein, low fat, and low cholesterol.
The history of the growth of the earthworm on the earth can be traced back to 350 million years ago. It is called the "living fossil," and it is the second-class national protected animal. It has extremely high academic and scientific research value, but also has a very high medical, edible, etc. Economic Value.
Since the 1960s, due to the destruction of the natural environment, illegal killing, smuggling, and sale of smugglers, as well as the lack of regenerative capacity of wild giant salamanders, the resources of wild giant salamanders have dropped drastically and they are in danger of depletion of resources. To this end, Hunan Provincial People’s Government established Zhangjiajie Provincial Daxu Nature Reserve in Hunan Province in 1995. In 1996, the State Council identified Guojian [1996] No. 113 document to establish the Zhangjiajie Daxue National Nature Reserve to protect Zhangjiajie wild Dagu resources. And its habitat.
Zhangjiajie City has a long history. It was originally called Dayong and is the seat of the ancient Dayong State. The Shang and Zhou dynasty belonged to Jingchu, and the Spring and Autumn and Warring States were the land of Chu. In 221 BC, the Qin Shihuang set up counties and counties, and established the first administrative district in Hunan Province, Langzhong County, in the Li River and Li River basins. It was one of the thirty-six counties in the country at that time. Today, two counties and two counties in Zhangjiajie City are under their jurisdiction. . The People's Republic of China was established in 1949, Zhangjiajie City was liberated throughout the country, and the Dayong and Sangzhi counties were under the jurisdiction of the Yongshun area from October 16, 1949 to August 1952, and were later placed in the Xiangxi Miao Autonomous Region and the Xiangxi Tujia and Miao Autonomous Prefecture jurisdiction, and Cili County until 1988 are all Changde District jurisdiction. On May 18, 1988, approved by the State Council, the prefecture-level city of Dayong was established in the Zhangjiajie area. Because the name of "Daiyong" is far less famous than Zhangjiajie, China's first national forest park under its jurisdiction. On April 4, 1994, Dayong City was renamed Zhangjiajie City. In 2008, the total population of Zhangjiajie reached 16.395 million, with a total area of ​​9563 square kilometers, and the municipal government was located in Yongding District.
Zhangjiajie's outstanding people, materialized Tianbao, long history of multi-ethnicity, ancient folk customs and unique customs and modern civilization each other, constitute a colorful cultural picture. Zhangjiajie is a place where ethnic minorities live in. In the course of long-term historical development, the Tujia, Miao, Bai and Han nationalities and other ethnic minorities have jointly created a distinctive national culture. This piece of heaven and earth resonates with the essence of the sun and the moon. Wonderland, for thousands of years, has nurtured tens of thousands of elite figures. The most famous of these are the proletarian revolutionaries, military strategists, and one of the founders of the Chinese People's Liberation Army, He Long, one of China’s top ten marshals.
Zhangjiajie is a treasure house of biological resources. Within the territory, there are 106 families, 320 genera and 850 species of woody plants and 146 vertebrates, including 56 species of national-level protected plants and 40 species of state-protected animals. The rare trees include Ginkgo biloba, Davidia involucrata, Taxus chinensis, Sakura, etc.; rare medicinal herbs include Ganoderma lucidum, Gastrodia elata, Polygonum multiflorum, Eucommia ulmoides, etc.; rare wild animals include giant salamanders, unicorns, Sumatran, South China tigers, clouded leopards, macaques, and civet cats.
The territory's special products are very rich, there are Otsuka products, "three treasures and a must", Gegen and so on.
In order to save the magical and endangered protected animals of Daxie, the local people of Zhangjiajie used the valuable information left by the predecessors and started a long and arduous research on artificial breeding. The history of Daxu's private feeding in Zhangjiajie can be traced back to the Warring States period. It is a strain of the Yangtze River basin. It is formed through long-term natural selection and manual selection based on local natural conditions and socio-economic conditions. Zhangjiajie's unique sandstone forest landscape, suitable climatic environment, abundant bait resources, excellent water quality conditions and long farming habits have produced Zhangjiajie Dagu with unique nutritional value, unique taste and excellent quality.
The scope of protection for production is: Zhangjiajie City, Hunan Province, and 2 municipal districts and 2 counties under the jurisdiction of the municipality, namely Yongding District and Wulingyuan District, Cili County and Sangzhi County.
Since the 1990s, the Zhangjiajie Municipal Party Committee and the Municipal Government have implemented the strategy of “cultivating and enriching the people with the characteristics of Daxie†and “promoting the conservation of Dalatian resources through rational development and utilization†relying on the advantages of the Dalat resources, ecological environment, abundant bait, and excellent water resources. The Daxie industry was used as a core project for poverty alleviation and the construction of a key industry in the overall well-to-do society in Zhangjiajie. The Zhangjiajie Daxie Industrial Development Leading Group was established and the medium and long-term development plan for the Zhangjiajie Daxie industry was formulated, based on the Zhangjiajie's landform, climate and environment. In terms of water resources, adopting the “company + base + farmer†industrialization model, and deploying large-scale breeding areas in Zhangjiajie according to local conditions, a large-scale breeding center has been established in 15 townships in Sangzhi County, Cili County, Yongding District, and Wulingyuan District. Zhangjiajie Economic Development Zone is building Zhangjiajie Daxie Comprehensive Utilization Base.
At present, there are more than 20 companies that have licensed domestication and breeding in Zhangjiajie Municipality, including one leading Hunan agricultural industrialization enterprise and one high-tech enterprise in Hunan Province. There are two large-scale operating licenses, and one Daxie Exhibition Management License. , The company commissioned more than 320 domestic and household agents. The city has more than 153,000 stocks of giant oysters, which produces an annual output of over 100,000 seedlings of big larvae, 49,000 pigs of the second generation of the year, and an output value of 250 million yuan.
With the development of the big breeding industry in Zhangjiajie in recent years, the Zhangjiajie Dalai has gradually become an important part of the tourism culture in Zhangjiajie, and the Dalat industry has gradually become one of the powerful auxiliary industries in the tourism industry in Zhangjiajie and is an important part of the economic development in Zhangjiajie. Due to the scarcity and uniqueness of Zhangjiajie Daban resources, its products are becoming high-end tourist souvenirs in Zhangjiajie. Zhangjiajie Municipal Party Committee and Municipal Government rely on the tourism resources of Zhangjiajie and strive to build Daxie as a new business card for Zhangjiajie.
Among more than 20 large-scale breeding companies in Zhangjiajie, Zhangjiajie Jinyu Biotechnology Co., Ltd. is the earliest private high-tech enterprise engaged in the domestication and breeding of Dagu. Its large-scale breeding technology is in the leading position in the country, and the large-scale breeding of products has a beautiful environment and cultivates the quality of Zhangjiajie. excellent. In order to further promote the Zhangjiajie amnesty, the company used the central set of "Science and Technology Expo", two sets of "Fortune Story", "Financial Hotline", seven sets of "Daily Agricultural Classics", "Getting Rich" and "Focus on Agriculture," and ten sets of "People and Society" "Encyclopedic Exploration" and many media at home and abroad such as the Asahi Television Station in Japan conducted special reports on Zhangjiajie Daxu. They have received tremendous response at home and abroad, setting off an upsurge in the protection and breeding of giant salamanders. Mr. Wang Guoxing, founder of the company also Respected by the CCTV media as "the father of Chinese juvenile fish."
(I) Sensory characteristics
1, the appearance characteristics. The Zhangjiajie giant salamander breeding technique completely simulates the natural conditions of the giant salamander and follows the habits of the mongooses. It does not acclimate the habit of hibernation and hibernation. During the hibernation period, the salamanders can effectively use the accumulated fat in the body. Therefore, the Zhangjiajie giant salamander has a relatively strong overall body shape without obesity. sense.
2, taste characteristics. Due to the low fat content of Zhangjiajie mutton meat, it makes the meat tender, delicious and unique in flavor with no greasy feel.
(b) Physical and chemical characteristics
Zhangjiajie Dagu fresh meat: moisture content ≥ 75%, protein ≥ 10%, must be amino acids ≥ 3%, fat ≤ 5%.
(3) Differences from other big officials
In other places, there are large defects or large amounts of meat or fat, or even shortcomings.
1. Comparison of protein content between Zhangjiajie euphorbia and other origins of euphorbia
Protein is the material basis of life. Without protein, there is no life. It is a substance that is closely linked with life and various forms of life activities. The level of protein content is an important indicator for evaluating the nutritional value of foods. Zhangjiajie Dagu meat has a slightly higher protein content compared with other far-reaching Dagu meat. This is inseparable from the good natural breeding conditions and abundant bait farming bait in Zhangjiajie. .
2. Ratio of Zhangjiajie giant salamanders and other origins of giant salamander meat and tail fat
Healthy human body has a very reasonable proportion of muscle and fat, and fat content is too high, which is known as obesity. It can cause many diseases and endanger human health. If the fat content is too low, it will result in low blood fat and hunger. Reduced ability also affects human health. Healthy scorpion and healthy human body, its muscle and fat composition ratio must be within a range, according to Otsuka Anatomy study, the fat of Otsuka is almost all accumulated in the tail of the big raccoon, therefore, can be evaluated according to the weight of fat of the scorpion tail The content of big fat. A further health research on Daxie showed that the golden ratio of healthy fleas and tail fat was between 14.5 and 15.5. A sampling study of the oyster meat from each of the country of origin found that the ratio of mutton meat to oil in Zhangjiajie was very reasonable and was clearly superior to other raw materials. Origin big brother.
3. Comparison of the growth rates of Daphnia magna between Zhangjiajie and other origins
The breeding period of general merchandise giant clams is three years. It is calculated from the hatching of giant salamander eggs and must be cultivated for three or more years before they can enter the market as commodities. If the time is too short, the body size and weight of giant salamanders will not reach the market. As a standard for the sale of commodities, when it reaches a breeding cycle, due to the difference in breeding methods and breeding environment, there will be certain differences in the size and weight of the big oysters from different places of production. We aim at the weight problem that most farmers care about most. A sample analysis was conducted on the three age groups in different producing areas. The results showed that the three age groups of Zhangjiajie were slightly higher in weight than other producing areas, indicating that the growth rate of Zhangjiajie giant salamander was faster.
4. Comparison of Fertility Rate and Survival Rate of Juveniles between Zhangjiajie Daphnia and Other Origins
The level of sperm motility directly affects the level of fertilization, and the level of sperm motility is determined by the male individual's sexual ability. It is an important manifestation of whether a male individual is healthy and strong. For the breeding industry of giant salamander, the cultivation of healthy offspring is an important guarantee for the success of giant salamander breeding. Therefore, it is very important to select excellent breeding species. In the breeding process of giant salamander, the fertility rate and the survival rate of pups are important for the quality of salamander breeding. Indicators, excellent seed pods directly determine the quality of the large-bred product obtained from farming. By comparing the fertility rate and survival rate of larvae of different production areas, we found that the fertility rate and the survival rate of young larvae in the breeding process of Zhangjiajie were significantly higher other areas.
