What separates the

What separates the "old gnawing family" needed to save America -! Snowstorm moderate valentine chicken coccidia infection only through and completed at least one life cycle in order to obtain immunity against coccidiosis coccidiosis only one type of reactor life period (5-7 days) you can build 90% of the immune system, soft coccidia to go through three life cycles to build a strong immune system, mixed infection of coccidia life cycle must be 2-3 to get a strong immune force. Chicken coccidiosis immunity is not permanent! Chicken if you do not give a regular opportunity to repeat an adequate level of infection, immunity against coccidiosis in chickens get will gradually disappear. Coccidiosis vaccine virkon s immunity is good or bad depends on the number of oocysts sporulated oocysts extent, content and actual virkon s intake of chicken. Immunogenicity of different virkon s balls in different virkon s species of worm. Immunogenicity giant pile type Eimeria best. There is no cross-protection between the various insect species of chicken coccidia, chickens must be vaccinated with the type of reactor, giant, displacement, soft four kinds of coccidia oocysts than seedlings. virkon s Breeders, laying hens must be vaccinated with the type of reactor, giant, displacement, soft, poison, precocious, Hastelloy, Brandt and other 8 kinds of coccidia oocysts seedlings. Immunogenicity of the same insect species are different at different developmental stages. The second virkon s generation of schizonts, merozoites most immunogenic.
Second, the process coccidiosis vaccine immunization method: 3-4 day old spray material immune immunity: 1, the preparatory work before immunization (1) chickens Empty: Empty chickens before immunization to two hours, and clean up materials disk, normal water supply. (2) material preparation: Distilled water or cold water; vaccine dilution vessel (commonly 20L-30L bucket or other container) virkon s two; pressurized sprayer one; canvas or hard plastic sheeting (use: Tile feed); rake or shovel wood a (Uses: Mixing feed); (3) calculate the feeding amount and quantity: feeding amount according to the day of intake of chicken 1/3 of total available ad libitum chicken for 6-8 hours. Such as 3-day-old immunization, per 1,000 chicks need to feed 8 kg, water demand (vaccine solution) 800-1200 ml. (Feeding amount adjusted according to the specific virkon s age and breed of chicken, the chicken should be enough to feed more than 6 hours). 2, immune operational processes virkon s (1) Tile feed: the weighed feed tiled in a prepared canvas or plastic sheeting or a clean hardened concrete floor. (2) dilution of vaccine: a good amount of water needed to be introduced into a clean part of the basin, and rinsed in water to open the vaccines and vaccine bottle cap five times, and the diluted solution was introduced into the vaccine spray and rinsing water with the remainder of the basin be added to the nebulizer. Can also be directly added to the spray water a sufficient amount, the vaccine vial is opened and the rinsing of the spray. Clean hands or other objects stir. Her own spray vaccine solution and shake a few times, you can spray material. (3) spray material operations: Before spraying material virkon s need not stop shaking all-round spray, then coccidiosis vaccine suspension was evenly sprayed on the feed back and forth several times more than the spray, spray side to side feed stir. Spraying should generally be mixed back and forth at least five times. (4), said material feeding: After the end of the spray material, based on the number of open pan, calculate the amount of feed intake of each dish should be allocated evenly to the feed tray as possible, in order to feed the chicks evenly. The spray vaccine chicken feed good finish, takes about 6-8 hours recording time feed required. Note: either shaking sprayer during spraying, twice shaking time shall more than 20 seconds; takes 2-3 officers to assist the spray material operation, in order to feed Stir; avoid precipitation oocysts, causing the immune uneven. The remaining material in the tray after eating plus new material. Three: virkon s a management point after immunization, expanding virkon s field: according to actual situation, to prohibit the expansion column virkon s in coccidiosis vaccine before and after the two days a week after the first, the second column should be expanded to take a small amount of litter scattered old to the new litter, the number of old litter should be taken to the old surface litter litter shared equally prevail on expanding the existing bar area after the flocks. 2, to ensure that material, adequate water: 1 day per 100 birds need an open pan, 150 chickens need a kettle; 2-3 days, every 75 chickens need an open pan, 100 chickens need a kettle (for reference), pay special attention to the water line for the uniformity of distribution and is leaking, if excessive moisture near the waterline or caked litter, virkon s should be replaced and add new litter. During prohibition immune feed off without water, leading to excessive litter pecking chickens. 3, vitamin supplements: 30 days ago, should be regularly added multidimensional in feed or drinking water, such as vitamins A, D, E is added to enhance the chicken's body, promote coccidiosis vaccine immunization. 4, litter management: If the litter is too wet or too much manure caked, should add a new litter or partial replacement of the original litter basis. Air and litter moisture and humidity requirements brooding stage coccidiosis vaccine required is the same (the space of about 60-70% relative humidity, litter grasping a wet feeling is appropriate to both humidity 25-30%). If the humidity is too big, you can enhance ventilation and add new litter. Litter dry, spray on the litter can be appropriate (timely water increases the humidity virkon s from the dust), maintaining litter relative humidity.
5, treatment of vaccine virkon s reactions: 14 days after the slaughter of the period, if there is a slight bloody or death by a chicken coccidiosis, is a manifestation of individual chickens react too heavy; local litter humidity is too large, individual chicken only cause leakage free immunization inequality is the main reason. Then please vote two days a therapeutic amount of DICLAZURIL or Amprolian generally administered two days can be. While adding new litter, increase ventilation and reduce litter humidity. Coccidiosis vaccine in chickens after three weeks will show significant growth advantage good uniformity, high survival rate, feed conversion ratio is low. 6, necrotizing enterocolitis treatment: immune coccidiosis in chickens during the immune response virkon s in the event, or they may cause necrotizing virkon s enterocolitis by the Clostridium infection, virkon s please virkon s vote three days penicillin virkon s antibiotics, such as ampicillin, amoxicillin Xilin, or add specific additives such as Clostridium Enramycin. Clostridial enteritis coccidiosis control helps build immunity. Note: 1, do not add any fed coccidiostat feed. Do not completely replace the litter before 2,28 days. 3, disinfection will not affect the immune effects of coccidiosis vaccine. 4, during the immunization containing the following ingredients prohibited drug or compound preparation (1) special chemical synthesis anticoccidial drugs: diclazuril, toltrazuril, nicarbazin, Kwai quinoline ester oxygen plasma carrier class: Mo Can neomycin, maduramycin, Lassa streptozotocin, salinomycin, etc. (2) tetracyclines doxycycline (doxycycline hydrochloride), chlortetracycline, oxytetracycline and tetracycline, etc. (3) sulfonamides sulfa drugs and synergist Chloropyrazine sodium, Sulfaquinoxalinum, sulfamethazine, sulfa drugs synergist such as trimethoprim (TMP) (4) drug chloramphenicol thiamphenicol, Florfenicol References: Yan Shi dare, chicken coccidiosis vaccine immune mechanism and proper use.
