Pig disease not only causes direct loss to the farm, but also causes the pigs to produce sub-health status and increase the cost of feeding. The current breeding mode and pig house structure in the domestic pig farms determine that the disease is difficult to purify in the farm. The emergence of many health care products and technology concepts has not been able to fundamentally solve the threat of disease to the herd. However, biosafety technology cannot be implemented in domestic pig farms, and health products and technical solutions need to be scientifically studied and Improvements can be adapted to the needs of the current farm.
First, the current problems in pig farm health care:
1. Excessive use of antibiotics. The overuse of antibiotics is also a common phenomenon in the pig industry. This is the result of the product education of the pig farm consumers and the weak professional quality of the pig farmers. Excessive use of antibiotics to cause drug resistance is an indisputable fact. The more serious consequence is that long-term use of antibiotics for "health care" causes pig liver drug accumulation, side effects of side effects frequently occur, and severely inhibits the acceptance of vaccine antigens by immune organs. The levels of antibodies produced after immunization with group vaccines are mixed.
2. Functional products still need to be improved. The live bacterial preparation is theoretically very scientific as a pig health product. The compound live bacterial preparation can inhibit the growth of harmful bacteria after being propagated in the digestive tract, and the bacterial vitamins and small peptide substances produced by the metabolism can provide nutrients for the immune organs. To improve the production of antibodies after vaccination, the current use of live bacterial preparations is not limited by the viability of the strains, the type of compounding, and the selection and production process of prebiotics; chitosan oligosaccharides are limited by the production cost in the pig industry. Promotion; antibacterial peptides are limited by the effects of gene expression.
3, can not be combined with nutrients. The essential amino acids, minerals, vitamins, etc. are prerequisites for the health of the herd. If the health care products are used for the pigs, the benign combination with the nutrients will be greatly reduced.
4. The breeding environment is poor. “Health care†is the abbreviation of ensuring health. The basis of any health care technology implementation is that the pigs are in a comfortable feeding and management environment. Whether the pigs are sub-healthy or sick, comfortable environmental conditions such as temperature, humidity, density and ventilation are exerted. An indispensable foundation for health care measures.
Second, the current problem of the use of traditional Chinese medicine products in the pig farm for health care
1. Chinese medicine is mixed with antibiotics. The combination of traditional Chinese medicine and antibiotics is the essence of some enterprises to promote the so-called traditional Chinese medicine products. In fact, the effect of Chinese medicine powder and antibiotics is not very good. On the one hand, many antibiotics will restrict the active ingredients of some Chinese medicines, on the other hand, Chinese medicine prescriptions and powders Oral mixing of antibiotics will increase the burden of digestive enzymes in pigs, and the effect is likely to be weakened.
2. The compounding of the extracted components of traditional Chinese medicine. The use of Chinese herbal monomer components is used to relieve clinical effects, such as glycyrrhizic acid, andrographolide, saikosaponin, berberine, quercetin and the like. However, the monomer components have certain physical and chemical constants such as melting point, boiling point, optical rotation, solubility, etc., and are easily affected by the extraction process, preservation environment, carrier, intestinal environment and the like.
3, Chinese medicine into a coarse powder product. Most companies use and promote the coarse powder of traditional Chinese medicine, which is easy to process. The disadvantage is that pigs do not secrete cellulolytic enzymes and lignin-degrading enzymes in monogastric animals. They cannot be digested and absorbed, resulting in greatly reduced efficacy. Most of the traditional Chinese medicines belong to medicinal plant subjects, and the plant cell walls are generally hard.
4, Chinese medicine ultra-fine powder products. Ultrafine powder of traditional Chinese medicine usually refers to more than 200 mesh fineness. At present, only a small number of Chinese medicine ultrafine powder can reach 300 mesh. The absorption of traditional Chinese medicine ultrafine powder products is very good, and the treatment and health effects are ideal. The disadvantage is that the cost is high due to small capacity and large loss, and some Chinese medicines (such as minerals, leaf buds, etc.) are too finely pulverized to affect the flowability, which is not conducive to the uniformity of mixing in the feed.
5. Health care medication is not dialectical. The herd is often in a state of health, sub-health, and morbidity, and the regulation of the body of the Chinese medicine prescription is based on the compatibility of the syndrome differentiation legislation. Many pig farm veterinarians can't dialectically treat them. In the case of pigs, a large number of Chinese medicines are used to damage the body.
Third, the future trend of the use of traditional Chinese medicine preparations for health care on the farm
Based on the advantages of traditional Chinese medicines versus antibiotics, the use of traditional Chinese medicine preparations for health care to prevent diseases is the main trend in the future pig industry.
1. New method of making veterinary traditional Chinese medicine preparations. The new way of processing Chinese medicine can obtain more excellent medicine. For example, anaerobic fermentation, heat-clearing and detoxifying traditional Chinese medicine products such as Bacillus subtilis and Saccharomyces cerevisiae can not only increase the palatability of the drug, but also improve the disease resistance of the pig.
2. New technology for the manufacture of veterinary Chinese medicine products. Using a new manufacturing process, the active ingredient of the drug can be fully released from the plant cell wall, and the efficacy is increased by 3-5 times. For example, the Chinese traditional medicine preparation is inoculated with cellulolytic enzyme and lignin decomposing enzyme, and is enzymatically hydrolyzed under suitable physical and chemical conditions. The cell wall of the medicinal plant can reach a breaking rate of more than 90%, and the efficacy is not only higher than that of the coarse powder and the super powder. Micro-powder, and good palatability, the mixture is easy to use and evenly mixed.
3. Innovation of compatibility formula. Using traditional Chinese medicine to prevent epidemics or promote pig production performance, the general group prevention and treatment method, the innovative adjustment of traditional Chinese medicine prescriptions can be more suitable for the current needs of pig management. For example, the health care Chinese medicine prescription used by lactating sows is adjusted to eliminate stomach and tonifying qi, nourishing qi and nourishing blood, promoting blood circulation and collaterals, dampness and relieving phlegm, etc., which can solve the problem of postpartum loss of appetite, mastitis, and increase milk production. Prevent the occurrence of various diarrhea in suckling pigs and achieve a multi-effect.
