近几年肉鸡成长急速病例上肌胃炎.doc

，The last few years, the vaccine immunity of the meat chicken, egg chicken although the density continues enlargement,the concern rate, case cure rate of plague is more and more low, produce function to year by year land, should arouse feedback also bigger and bigger, the dead Tao leads year by year rally, breath way disease, bowel way the disease Be long to dont more cure.Everyone all at the deliberation for continuing, actually was that topic?Is actual to prove, the immunity surrenders with fungi toxin of taint with, is the invisible cutthroat of two importance that invites an above-mentioned view of domestic fowl to meet.An immunity represses and the immunity extort a disease1.1 scenes1.1.1 flow out should arouse feedback now.While preventing epidemic disease as usual for chicken machine bodys canning not to cannot compare with to conceive to take place the immunity that should have should answer, antibody even degree bad;Inoculate a breath way vaccine respond violent, dont have the breath way the symptom while doing not inoculate, inoculate to namely start to be suffused with to shout after 12 days, jilt a nose and cough etc. breath way symptom;The egg chicken inoculates oil seedling and starts to be suffused with to produce egg landings etc.1.1.2 production functions are deep and low.If the meat chicken grows to develop badly, the weight Be wrong to fall not and together, the feather develop bad, present one partJiang chicken, extremely with young Chu is heavy;Producing function is bad, such as the meat chicken anticipate meat to compare Gao, the egg chicken produces egg to lead low, produce egg high peak to expect to insist short.1.1.3 resist dint to fall low.The disease delivers more and be infected disease arouse symptoms of disease of having the problem a little bit really, if paying an original body, E. coli and ball the insect is far-gone.1.2 temperamentsThe immunity organ, organization and cell of chicken is damaged, cause the immunity system obey orders to dont as usual and outward promote the boundaryantigen to stimulate feedback low, outward to the cause infection resist dint to descend, namely the machine body took place immunity to coerce.The immunity surrenders a disease to mainly influence the machine body immunity odd pieces, can make the machine body take place the immunity of non- palliation and hard repair surrender.1.3 reasonsRepeatedly in the last years, on the case various virus disease cause the poison stub variation and atmosphere happen to continuously strengthen, lately the diseases hair and hard control more of the current situation show Zhao more and more.In order to guarantee a farming to win, farms defending to control aspect in the disease must measure through number of times and of promoting the immunity to reply.With egg chicken bird flu epidemic prevention for example, the original doesnt need to be prevented epidemic disease, it the general chicken field want to do two immunity to the H9, the H5 does 4 immunities, separately in order to guarantee assure immunity scholastic attainment, the region also factitiously enlarges epidemic prevention amount of, again add of the epidemic prevention of other normal disease epidemic prevention, new outbreak, make the immunity of chicken should to system from at first normal task shape change is long-last of super burden status, machine body namely flow out nowthe immunity presses the Na.Currently, the initial immunity of clinical top chicken squeezes a disease to have:Shout the bowel Gu virus, skin organization inside the net increases to living a disease, method surname a bag burning, the surname disease of Ma Li Ke, J-second cluster of leukemia, contagion blood falsely, fungi infection etc.1.4 controls1.4.1 to build ups feed a plan and enhance living creature safely defense measures.The animal feed that uses whole price nourishment, ease possibly or the anti- resist breeze, light, cold, heat, degree of humidity, happy sound etc. should arouse the influence of the factor upon the chickens;Constuct good living creature peaceful system, concern chickens to be free from or little be subjected to hit of the outside source cause microorganism.Found a spare chicken and produce an egg chicken to feed respectively, adjust organization, further list stem;Carry out whole enter the Huan of whole keep to carry out track system.1.4.2 slice to indeed use medicine.According to the paroxysm status, the reasonable decides to make use of medicine.The treatment has to be fitting and defendoofs to soon definitely apply while making use of medicine;The Jun is fierce to apply sugar skin quality hormone(the adrenal glands skin quality hormone) according to the use category, the tube even if defendoofs to use A Mao mildewed vegetables etc. oppresses the medicine of inspiration mightiness to the immunity, in order to prevent constitute the immunity defeat in battle.Before immunity or immunity of at the same time, fitting usage immunity to build up such as left Xuan Mi Shi etc., can go forward a machine body immunity efficiency, avoid the occurrence that the immunity overcomes.Many medium herb medicines can also progress the antibody level and immunity dint of machine body.If the benefit Chinese herbal medicine mostly has much sugar composition, is much sugar, Huang Mao Duos sugar, and party more than three sugars.etc. such as the ginseng, can go forward the machine body immunity observance;The pure heat counteracts poison a type of Chinese herbal medicine such as plank blue root, the fish Xing grass, golden thread, Huang Qin, Huang Bo, wore heart lotus etc. to have the machine body immunity to strengthen a chicken obey orders of reform, the type of medicine can also invalidly inhibit stiring up of cause germ, can used for contagion paroxysm prevention and cure.1.4.3 slice to indeed make a choice vaccine and living creature finished product.The to build up coerces the immunity of disease towards growing the chickens virus immunity, mother the source antibody provide to the future generations and make son generation the chicken acquire active good care in the low day age and keep the immunity that the chickens present a later period from winning an infection, useful defend to make paroxysm of occurrence.But in the immunity should establish a reasonable immunity path and pace according to the concrete circumstance of farm, strengthen an antibody monitor.But increase to living disease virus to the skin organization inside the birds leukemia and the net, under the sistuation that today still lack invalid vaccine prevention control, can rely on an impressionable diagnosis method to check a male chicken of to fall behind a line to eliminate to is to even need to strengthen diagnosis and epidemic situation survey and attain to as early as possible create and early as possible reduce the chicken of taking the poison disease, the decontamination kinds.At use weak poison vaccine of divide, settle however want to pay attention to original material of the chicken Pei of producing the factory house of source, scathing forbidden not SPF source head of weak poison vaccine, preventfrom because of vaccine pollution but the infection of artificial composing chickens.Creating the SPF chicken Pei that the domestic fowl vaccine is used must through 17 kinds of examinations of causes(13 kinds of virus diseases, 2 kinds of germ diseases and 2 kinds pay an original body), the fact feminine gender square can use.Not SPF chicken Pei because there is antibody in the egg and squeeze virus to propagate and cause the vaccine amount of antigen lack.Produce a chicken used in vaccine the Pei tainted with an outside source sexually transmitted disease original, pretty much is an egg notification of cause, supposed a chicken to use to live to also taint with an outside source cause in the vaccine.The vaccine that the cause that these eggs deliver taints with may follow the application of vaccine to perpetrate immunity to oppress or the immunity defeat in battle, or make the immunity chickens have an attack and factitiously constitute paroxysm Sa to sow.The pollution of 2 fungi toxins2.1 weathers2.1.1 meat chickens.The last few years, the meat chicken grows up rapid, muscle stomach inflammation, gland stomach inflammation of case case much hair and long dont more cure;Diarrhea omen has much of a problem, the ball insect enteritis several times repeatedly goes into action, E. coli the easy reasonableness strengthen;The farm door doesnt dare to stop a medicine and promoted medicine fee devotion and had much of the problem influence the animal feed wages with normal grow up;Flowed out now the immunity of old fire to win, vaccine immunity after, the antibody in the chicken body cans not to cannot compare with to arrive the drop that should have degree, feeding expects easy reasonableness of etc. of the non- model epidemic disease, bird flu in Hsin-cheng virus paroxysm to consumedly strengthen behind, and the farming risk is bigger and bigger.2.1.2 kinds of chickens.Produce amount of egg, conceive a rate, dead Pei rate, hatch from eggs rate to lower, eggshell breeze to land, the immunity represses diseases to deliver more.2.1.3 egg chickens.Produce amount of egg, eggshell character to descend, have much of the problem influence the production function of the egg chickens.2.2 propertiesThe species of fungi toxin very many, initial have Huang Qu of syphilis vegetable, the He song syphilis vegetable and corn red mildewed Xi Tong, vomit mildewed vegetable and toxin T-2 etc.Among them, the Huang Qu syphilis vegetable mainly perpetrates poisoned sex hepatitis, the Zhe song syphilis vegetable is initial to arouse liver of cell not quite right dead and kidney disease, the corn red mildewed Xi Tong causes babys(embryo) abnormal, multiply function to descend, vomit negative the toxin perpetrate immunity function mess and kidney disease, the toxins T-2s arouse still-born baby and stir up function abnormality.Each kind of fungi toxin may have several Ba organs probably many cells of species type.Various fungi toxins are together reformed to a machine body, their harm levels are to in brief and mutually add and usually become to double to grow.2.3 reasons2.3.1 animal feed raw material the mildew change in character.The mildews, such as the corn that the animal feed guessed right at first, bean Po and fish powder.etc. transmuted, is caused the chickens fungi toxins being infected with the result that poisoned direct cause reason.The change of Huan ball the weather breeds to provide a good condition for fungi growth.Corn at harvest seasonal changes rain water just the right amount of, the possibility has been already become mildewed in the ground before harvesting, after harvesting not ability actually sun, invite become mildewed to transmute.The mildewed changes the corn conceive the toxin of occurrence to mainly have Huang Qu s fungi and red mildewed Xi Tong, vomit a mildewed vegetable etc.Bean Po and fish powder are in the process of keeping in will also purify fungi, erupt to living fungi toxin.2.3.2 animal feed raw material price whereaboutses are to the influence that the fungi toxin is poisoned.The albumen animal feed guessed right at first, rapeseed Po, the cotton seed Po, peanut a round flat cake and sunflower Ren a round flat cake, coconut powder and palm tree Ren powder etc., compare ultra conservative albumen animal feed the raw material was like bean Po, altered to purify fungi toxin.When the price whereabouts of ultra conservative animal feed raw material of divide, the animal feed produces a business enterprise and then will make a choice to make use of a replacing of bean Po article, and then this several rates that increased fungi toxin to be poisoned.Equally, the whereabouts of corn price, will also direct animal feed to process a business enterprise to account an argument in addition energy animal feed raw material to replace an article and search to gather rice chaff and wheat Fu by-product etc.;The usage of by-product and animal feed raw material substitute increases, although can float in the sky an animal feed resources,also make and lead into the decontamination fungi toxin of several rates of raw material consumedly increased.2.3.3 mats anticipate infection.The air keeps the mat of chicken to anticipate initial have peanut shell, rice hull, wheat Ji, and sawdust.etc., in the heat under the high wet circumstance, these mats anticipate easy mildew.Eat mat to anticipate in the farming may drop is anticipating mat the last animal feed, can invite a fungi infection or eat into fungi toxin.2.4 lead long to make2.4.1 make good feeding to raise a painting, the tube even if sweeps m
