Develop microbial resources and promote sustainable development of animal husbandry

Introduction: in the vast world, all things are endless, and the material cycle is transformed because of the material cycle chain in nature Plant, animal and microorganism constitute the main chain of biological cycle, in which plant is the producer, animal is the consumer, and microorganism is the transformation and reduction Due to the fact that microorganisms can not be seen or touched, the understanding and utilization of them are very limited in agriculture Human agricultural activities are mainly the development of plant and animal resources, which is a kind of "dual structure" model of resource waste In the "dual mode", a large number of crop straw and livestock and poultry breeding waste can not be fully converted and utilized, resulting in a huge waste of resources, but also a huge pressure on the ecological environment Dr Qin Zerong, who has been engaged in the research of animal diseases and microbial technology industrialization for many years, said that only by attaching equal importance to the development of three kinds of resources, namely plants, animals and microorganisms, building a "ternary structure" model that can be recycled, and following the law of biological cycle, can agriculture and animal husbandry develop sustainably At present, China's animal husbandry is developing rapidly, and the proportion of output value in the total agricultural output value is increasing At the same time, animal husbandry also faces three dilemmas: environmental problems, quality and safety problems, and efficiency improvement problems Environmental problems become the most urgent problem According to Dr Qin, due to pollution, the development of breeding industry is restricted more and more, which directly affects the rural economy and related industries, and many farmers and related industry personnel will lose their jobs From the aspect of environmental ecology, the ecological chain of agriculture will not be maintained, and the planting industry will inevitably increase the dependence on chemical fertilizer, which may cause new environmental problems If we do not strengthen the governance, the threat to the water source, rivers, lakes and groundwater will not be avoided The only way out is to carry out the ecological management of breeding and realize the sustainable development of animal husbandry The microbial technology will play an irreplaceable role How microbial technology can play a role, Dr Qin elaborated from six aspects The first is to apply it to feed, promote digestion and absorption and reduce organic emissions There are a lot of organic nitrogen and organic phosphorus in livestock manure, which are the source of bad odor Microbial technology is used in feed, and feed conversion rate can be effectively improved by adding microbial metabolic products (such as lysine), microecological agents, microbial enzyme agents and using ecological feed Reduce the emission of nitrogen, phosphorus and other major organic matters At present, there are dozens of microorganisms, microbial enzymes, which have been approved to be directly added to feed The second is to enhance the disease resistance Disease is the most uncontrollable factor affecting the efficiency of aquaculture, and improving disease resistance is always an important part of ecological aquaculture Using microbial ecological products to improve the disease resistance of livestock and poultry, especially to reduce diarrhea and other diseases The third is odor control It can effectively reduce the generation of odor by spraying microbial agents in the enclosure, dunghill and cesspit of the farm The fourth is to deal with the excrement of livestock and poultry and realize the reuse of resources It can produce organic fertilizer, edible fungus culture medium and biogas to turn waste into treasure The fifth is the treatment of aquaculture wastewater Microbial technology has been widely used in wastewater treatment process, which makes aquaculture wastewater discharge, recycling and aquaculture The sixth is to improve the safety and quality of livestock products The application of microorganisms can greatly reduce the use of antibiotics and other additives, reduce drug residues, improve product safety, and further improve product quality and competitiveness There are many potential for microbial technology, such as the use of photosynthetic bacteria and marine red yeast can change the yolk color and improve the quality of eggs According to Dr Qin, through the comprehensive application of microbial technology in the above aspects, we can improve feed reward, improve the disease resistance of breeding products, reduce the generation of breeding wastes and the harmless utilization of wastes, which not only can control pollution, but also can greatly improve the comprehensive benefits of the breeding industry He stressed that with the introduction of the simple use concept of silly cameras into the promotion and application of microbial technology, the problem of "well used and affordable" for farmers will be solved When it comes to how to speed up the application of microbial technology, Dr Qin believes that the first is to improve laws and regulations Establish and improve laws and regulations, control breeding pollution according to law, and ensure the sustainable development of environmental protection animal husbandry Establish an environmental assessment system for similar industrial projects, and implement a quasi breeding system for large-scale breeding enterprises Second, we should carry out experiments and demonstrations Carry out demonstration of new ecological animal husbandry mode and improve technical details Third, we should support the ecology and feed back the ecological breeding At the same time, ecological breeding should be one of the contents of the industry and the city, and the farmers of pollution-free ecological breeding should be given appropriate subsidies and rewards in the early stage It is gratifying to Dr Qin that his reference has now attracted the attention of relevant parties Liu Qi, Secretary of the Beijing Municipal Party committee, gave instructions on April 18, instructing relevant departments to consider starting from the pilot He said that with more and more people's attention and participation, the spring of microbial development and utilization is coming.
