The new trend of pig industry in China

Introduction: with China's accession to the WTO, China's pig industry will have good opportunities for development, but also face severe challenges The status of pig production will change, and the technological development will be more rapid The ability of producers to respond to this changing situation will largely determine their future competitiveness and development prospects As people pay more and more attention to the safety of food, the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China approved and issued eight national standards related to the safety and quality of agricultural products on September 6, 2001, and the Ministry of agriculture also published the first 73 industry standards of pollution-free agricultural products on September 7, 2001, all of which have been in the whole country since October 1, 2001 Implementation At the same time, the Ministry of agriculture launched the "pollution-free food action plan", and its pilot work has been carried out in Beijing, Tianjin, Shanghai and Shenzhen With the improvement of people's living standards, people's awareness of environmental protection is also growing The management measures for pollution prevention and control of livestock and poultry breeding adopted by the State Environmental Protection Administration on March 20, 2001 is a clear proof In the face of these new situations, China's pig enterprises should have sufficient ideological preparation and corresponding countermeasures 1 In the era when the green consciousness is deeply rooted in people's minds, the layout of pig enterprises will change in two aspects Most of the pig raising enterprises will tend to the sales market, including the export market and areas with strong technical strength In today's market economy, the market sales will determine the demand for pigs and the price of pigs The pig breeders close to the slaughterhouse have an advantage in this respect Dkf's powerful enterprise groups will tend to produce high-quality livestock products in areas with good climate and water resources and rich land resources The appropriate climate environment is conducive to the healthy growth of pigs, which is conducive to the production of high-quality organic livestock products However, in those very hot or very cold areas, the cost of temperature isolated enclosure and indoor cooling or heating equipment is quite high Sufficient high-quality water source is the necessary prerequisite for large-scale pig production Poor water quality will greatly reduce the production performance of pigs and increase production costs With the increase of water consumption, the groundwater level in some areas using groundwater has decreased, which has caused people's concern about water In the future, the water source is likely to be the main factor determining the location of pig farms Due to the improvement of people's awareness of environmental protection and the arrival of the era of meager profits in animal husbandry, the reasonable use of manure will become an important part of the pig farm Manure is a high-quality organic fertilizer, so the land area that can be used to deal with manure will be an important factor determining the scale and location of pig enterprises With the improvement of science and technology and living standards, the utilization of pig dkf has also shown a trend of diversification, which can be used as food, medicine, industrial raw materials, experimental animals and bioreactors, as well as as as pet entertainment In the new century, there will be profound changes in the content, structure and means of pig breeding Breeding content the development trend of breeding content is that the breeding direction is more and more diversified In addition to the mainstream breeding direction used for food, there will be more and more specialized varieties used for medicine, industrial raw materials, experimental animals, bioreactors and entertainment, among which the varieties used for food will also develop in the direction of high-quality meat DKf Breeding structure: the development trend of breeding structure is that the core groups are more and more scattered and tend to be internationalized, and the production of Hybrid Pigs becomes the mainstream; the members of breeding structure are increasing gradually, and the breeding company and the national breeding program are combined Various pig farms establish genetic linkage through artificial insemination, and analyze the information of core groups, breeding groups, commodity farms, slaughterhouses and artificial insemination in a unified way In reference to the development and adjustment of breeding programs at any time In addition to the traditional breeding methods, dkf breeding technology is widely used in pig breeding practice, including gene QTL mapping technology of genome and important economic characters, molecular biology technology of super high yield breeding and molecular biology technology of genetic resource protection and utilization There will be new changes in feed formula, feed additives and feed formulation The NRC model is not suitable for China's national conditions due to different pig breeds and feeding environments Therefore, China needs to develop a formula model suitable for its own national conditions Feed additive the development trend of feed additive will be gradually integrated into the world trend of pollution-free and green, especially the enzyme preparation, probiotics and Chinese herbal medicine additives will be developed rapidly The puffing technology, pelletizing technology and spray mixing technology after pelletizing of feed compounding will be fully applied, and different methods of different pig groups using different particle sizes will also be concerned by people In the aspect of feeding management, the methods of all in and all out, isolation early weaning technology, utilization of excellent genes and feeding by sex and stage will be applied to production In addition, people will pay more attention to the design of the chute The whole in and out system can reduce the incidence rate of pigs, but should be combined with thorough cleaning and avoiding cross infection between pigs and pigs Dkf isolation early weaning system will be used in the pig farms where conditions permit When the protective maternal antibody is still at a high level, early weaning can avoid the vertical transmission of the disease from large pigs to small pigs The continuous isolation of pig population prevented the horizontal transmission of pathogenic microorganism The earlier the weaning age is, the fewer the diseases the piglets are infected with The most common weaning age is 14-16 days Dkf multi-point management is an increasingly important management technology in isolating early weaning procedures The technology needs to isolate early weaned pigs from other pigs in the farm to prevent disease transmission The greater the spacing between the pig houses in the pig farm, the better All facilities shall be designed according to the strict principle of all in and all out The utilization of dkf fine gene can make full use of the fine gene of the pig farm by establishing the core breeding pig group of the pig farm, or introduce the fine boar semen outside by artificial insemination, so as to improve the production performance of the pig farm Compared with the castrated boar, the growth of sows is slower, the feed intake is smaller, the conversion rate of feed and weight gain is better, and the carcass lean meat rate is higher when the same body weight The lysine requirement of sows was the same as that of castrated Boars of the same weight The formula can be made according to the difference between the demands of male and female pigs Feeding by sex can not only improve the utilization rate of feed, but also improve the evenness of listed pigs At the same time, it can also postpone the time for sows to go on the market The nutritional requirement of modern pigs fed with dkf in different stages changes rapidly, especially in the early stage of growth and even in the finishing stage In order to give full play to the genetic potential of pigs, the growth of pigs should be divided into more feeding stages 12 different formulas can be used in conditional pig farms, while 16 formulas can be used in sex fed pig farms The design of dkf feed chute may play an important role in feed consumption and feed waste If the pig is not comfortable when eating, the intake will be reduced, and the average daily gain will also be reduced It is also very important to constantly adjust the feed chute Without proper adjustment, the pig's feeding will be affected DKf
