Background technology
Along with the rise of intensive aviculture and the increase of international trade, fowl diseases is popular to be on the rise, and causes the high mortality of poultry, seriously governs the development of poultry husbandry, causes the loss that world's poultry husbandry is serious, jeopardizes economic development, food safety and social stability.Infectious bursal disease (Infection bursal disease, IBD) be by infectious bursa of Fabricius virus (Infection bursal disease virus, a kind of high degree in contact sexually transmitted disease of the chicken IBDV) caused and turkey, main infection 3-12 week age young chicken, this virus is mainly in the lymphocyte internal breeding of fabricius bursa, and damage is in various degree caused to other immune organ, finally causes the fabricius bursa atrophy of chicken and cause the immunosuppressant of chicken.This disease is without significantly seasonal, all can occur throughout the year, propagate usually through approach such as contaminated feedstuff, drinking-water, feces, hen house apparatus, staff garments, incubation period is 1-5 days, and after there is symptom the 3rd day starts dead, within 4-6 days, be peak mortality phases, stop death gradually later, sickness rate can reach more than 90%, and mortality rate not etc., is not generally 10%-50%.Primary disease can cause losing weight clinically, poor growth and the symptom such as skeletal muscle is hemorrhage, often occur together when sanitary condition is poor other diseases, mortality rate improves further, and chickling individuality is little, and premunition is poor, once generation epidemic disease, then infect fast, mortality rate is high, and mortality rate reaches more than 80%, loss is larger, has carried out huge economic loss to poultry industrial belt.
Vaccine is the goods be made up after breeding and process of the good pathogenic microorganism of immunogenicity, after inoculation animal body, body is stimulated to produce specific antibody, after the antibody titer in body reaches certain numerical value, just can resist invasion and attack, the infection of this pathogenic microorganism, play the effect preventing this disease.Along with the fast development of China's aviculture, more and more important to the control of infectious bursal disease.
Polysaccharide is one of active ingredient of Chinese herbs, and large quantity research shows, polysaccharide and saccharide complex are not only in vivo as energy resource and constituent material, the more important thing is that it is present in all membrane structures, participates in the various activities of cell in biosis.Polysaccharose substance is the important component part of all Living organisms, has scavenging free radicals, improves the ability of activities of antioxidant enzymes and anti-lipid peroxidation.
Vitamin is requisite organic compound in organism metabolism.The chemical plant that body is very complicated just as one, constantly carries out various biochemical reaction.Its reaction has substantial connection with the catalytic action of enzyme.Enzyme will produce activity, and coenzyme must be had to participate in.Known many vitamin are the coenzyme of enzyme or the ingredient of coenzyme.Therefore, vitamin is the important substance maintaining and regulate body homergy.Vitamin is one of indispensable nutrient substance in growth of animal process, and especially when occurring, the effect of vitamin is more obvious.Suitable edible vitamin can reduce Animal stress, reduces disease incident, improves animal disease resistant ability.
Flavone compound is the polyatomic phenol material that occurring in nature exists, and is also one of main active in nature medicinal plants.It refers to have 15 carbon atoms and with the three ring natural organic matters that the mode of C6-C3-C6 is formed, be the secondary metabolism product that plant produces in long-term natural selection, now isolation identification have kind more than 4000.It is extensively present in fruit and vegerable, Chinese herbal medicine, have no side effect, it has the medicine healthy sofa functions such as significant scavenger interior free yl, aging resistance, mutation, Adjust-blood lipid blood pressure lowering, it is the natural organic oxidation-resistant agent that a class has DEVELOPMENT PROSPECT, these anti-oxidation active substances can reduce and scavenger interior free yl, have prophylactic effect.
Probiotic bacteria has prebiotic effect to people and animals.Probiotic bacteria in microbial ecological agent can produce antibiotic substance, and competes the Ecological niche with noxious bacteria, suppresses the growth and breeding of pathogenic bacterium, the colony balance of adjustment and recovery intestinal.In addition, microbial ecological agent can become the nonspecific immunity factor, and by antibacterial itself or cell wall constituent stimulation of host cell, activating immune system, improves body antibody horizontal or macrophage activity, thus enhancing body resistance.Profitable strain in microbial ecological agent is multiplied at digestive tract, can in facilitating digestion road a series of nutritional labeling such as several amino acids, vitamin effective synthesis and absorb, thus promote animal growth and development and weightening finish.Simultaneously in environmental protection, fecaluria stench can be removed, purifying ecological environment.Probiotic bacteria in microbial ecological agent decomposes and synthesis by carrying out fermentation to harmful substance, effectively reduces the content of poisonous and harmful substance.
At present, commercially available microbial ecological agent is mostly lyophilized powder, and can directly mix in feedstuff, oral administration mode be absorbed by animal body.Although this feed mode is simple and convenient, because microbial ecological agent is mostly lactobacillus, its vitality is comparatively fragile, mixes and significantly can reduce viable count in feedstuff.In addition, because same feedstuff is fed jointly, be difficult to the accurate-metering ensureing that animal absorbs, thus affect the treatment.The product of lyophilised state all will remain on " cold chain " environment under lower state of temperature in the whole storage used and transportation in addition, and this brings inconvenience to the storage of product and the use of transport and user.
