Scientific and efficient pig industry in Denmark

Introduction: Denmark, known as the "pig kingdom", covers an area of 43000 square kilometers and has a population of only 5.3 million In recent years, Denmark, relying on advanced modern biotechnology and unremitting research and development of excellent varieties, has always owned the world's first-class pig breeding, thus becoming a first-class pig breeding country Now there are more than 20000 pig farms in Denmark, with an annual per capita production of more than 300 kg of pork, 80% of which are for export In 1999, Denmark's pork exports reached 22 billion kroner (about US $900 million), accounting for 7% of Denmark's total exports, 43% of agricultural products exports and 23% of the world's total pork exports, which is truly the world's first The reason why Denmark has such remarkable achievements in pig industry is that its experience mainly includes the following aspects: elaborately cultivating first-class pigs, relying on modern biological science and technology, increasing investment in research and development of excellent varieties, and continuously cultivating world-class pigs are the most fundamental experience for Denmark to become a first-class pig raising country The Danish national production Commission has organized and implemented the Danish breeding program for breeding pigs (hereinafter referred to as Danyu), which aims to improve the breeds of Danish pigs In order to complete the project, Danyu has combined 42 pig farms with 72 pig herds According to the different characteristics of different breeds, different breeds of sows and boars are used for cross breeding In the process of breeding, 90% to 9% of sows adopt the method of artificial insemination, which can establish the genetic relationship between different pig groups, prevent inbreeding and ensure the optimization of breeds In addition, SPE method has been used in breeding pigs in Denmark to improve the quality of breeding pigs This method is carried out in the pig farms with the best sanitary conditions and under the technical guidance of professional companies Play the role of Industry Association in Denmark, the pig raising and slaughtering Federation is a cooperative self-help organization of farmers All pig raising farms, slaughterhouses and their enterprise departments are members of the Federation The development of cooperatives is the realization of each member's own economic interests Zhuangden, the pork production industry has implemented a series of quality assurance measures for the processing of meat products, which has reached the world's highest health standards At the same time, they also established a complete and reliable traceability chain system for food processing and production, namely "Genealogy" As far as food production is concerned, the raw materials used in food production of enterprises have original source records, use records and flow direction records, as well as continuous records of various storage, transportation and sales links of finished products Once problems are found, they can be traced back to the source and found out in time through computers In recent years, Denmark has stepped up the development of environmentally sound feeding technology, made efforts to reduce environmental pollution, and thus accelerated the development of large-scale pig breeding Denmark's pig feed mainly consists of grain, with a small amount of oil cake, animal fat, meat and bone meal, protein, etc it is strictly prohibited to add growth hormone such as growth hormone and growth hormone in the feed The feeding of pigs is guided by science to improve feed conversion rate, and the transportation of pig feed is fully automated The daily intake of pigs is also controlled by computers, and they are fed regularly and quantitatively according to different growth periods Denmark also attaches great importance to the judgment and detection of salmonellosis Since 1999, Denmark has implemented the project of salmonellosis control of pork products, focusing on how to further control salmonellosis by improving feed At present, the detection rate of Salmonella in Danish pork is 1% At this point, only Sweden, which is famous for its green pig breeding, can be as famous as Denmark The Danish Federation of pig breeding and slaughtering also attaches great importance to the improvement of relevant technologies of pig houses and production systems, so as to improve the health conditions of pigs and improve productivity In addition, the law also limits the area of the farm and the number of livestock that the farmer can own Generally, when the farm reaches a certain scale, the relevant departments and institutions need to assess its environment, and decide whether it can continue to expand the breeding scale according to the assessment results.
