Livestock husbandry provides human nutrition-rich and delicious animal products. At the same time, it also causes pollution to the environment and water sources on which human beings live, and directly or indirectly affects the conditions for the production of green livestock products. The key technical measures for the production of pollution-free pork are high-quality, safe feed and feed additives. Feed ingredients should come from grassland and planting bases in non-environmental areas. All kinds of compound feeds should come from companies that have production licenses, and should be formulated in strict accordance with the nutritional needs of pigs at each stage. There are product standard documents and they are not used in production and storage. Pollution or deterioration is forbidden to use moldy spoilage, pollution, and counterfeit and inferior feed. Feed additives can increase the feed conversion rate and growth rate, and increase the economic benefits of raising pigs. However, antibiotics, hormones, sedatives, stimulants (such as lean meat), and metal ions (such as copper and arsenic) that were used in the past should be strictly prohibited, preventing the residues of these toxic and harmful substances in pork and its internal organs from harming humans through consumption. We should actively research and develop additives that have health, disease prevention, and growth-promoting effects on pigs, and do no harm to human health and the environment. In recent years, trial and research and production practices have proven that probiotics, bifidobacteria preparations, Chinese herbal medicine additives, biologically active peptides, enzyme preparations, amino acid chelating mineral element preparations, and immune promoters (such as oligosaccharides, vitamin E), etc. With the characteristics of health care, disease prevention, growth promotion, no residue and no pollution, the environment-friendly and safe green feed additive has a good application prospect.
At the same time, it should also strictly manage and standardize the use of veterinary drugs. It is forbidden to abuse the therapeutic drug by random purchase or increase the dose arbitrarily, change the method of drug use, and try to use high-efficiency, low-toxic, low-residue or element-free drugs. Strict implementation of the provisions of the competent department on the withdrawal of all antibiotics for at least 30 days before the withdrawal date and live pig slaughter. At the same time, regular inspections should be conducted on the detection of residual toxic and harmful substances in pig feed and pigs, and a comprehensive analysis system should be established to establish a set of scientifically regulated live pigs management and quarantine prevention systems and to implement them in a conscientious manner in order to ensure institutional and concrete measures. Green pork raw pig production.
With the development of social economy in our country, improvement of people's life quality and advocacy of green food consumer products, people advocate natural, healthy, food-free, no-forbidden additives, and green pork without prescribed disease, which is the consumption of meat food. In the future, sales of green pork will increase rapidly. Accelerating the development of green pig production is the only way to improve the safety and quality of pork, and promote the transformation of pigs from extensive quantities to quality and efficiency, and achieve sustainable development.
