10 Ways to Improve Chicken Immune Effects on Drinking Water
1 Use highly effective imitation attenuated vaccines. Before drinking water, we must pay attention to the quality of the vaccine, the effective period, the transport, storage, and storage of the vaccine. Poor, expired vaccines and improperly stored vaccines should not be used. 2 Thoroughly rinse the water system and drinking equipment before drinking water, but do not use disinfectants and detergents. Drinking equipment can not use metal products, it is best to use porcelain and plastic appliances. 3 drinking water immunization water should be distilled water or cold water or clean deep well water. Water should not contain heavy metal ions and halogen elements. Tap water should be boiled and left overnight before use. For large chicken farms, oxygen can be added to tap water. Add 10% sodium thiosulfate 3-10 ml per 10 liters of water depending on the amount of chlorine in the water. 4 The vaccine should be bottled and poured into water. Stir with a clean wooden stick. If the outdoor wind is large, it should be diluted indoors. It is best to add 0.20%--0.50% skimmed milk powder or sorbitol to the diluent to protect the vaccine titer. 5 Drinking water should be stopped for 3 to 6 hours before immunization. The length of water withdrawal should be controlled flexibly according to room temperature and feed dryness and wetness. When the dry powder is fed at high temperature at room temperature, the water stopping time is shorter, and when the wet material is fed at low temperature, the water stopping time is longer. 6 Before drinking water, you must increase the number of drinking fountains according to the number of chickens and the size of the chicken. Make more than 90% of chickens drink enough vaccine water at the same time. When the flock is large and the drinker is insufficient, it can be done in batches, so that it can be diluted with drinking water to prevent the vaccine water from failing during the procrastination. 7 Diluted vaccine water should be suitable, not too much or too little, should refer to the vaccine instructions and the size of the immunized chickens, the number and the room temperature at that time to determine. Vaccine water should be consumed within 1- 2 hours, but in order to allow each bird to drink a sufficient amount of vaccine, the drinking time should not be less than 1 hour. The general dosage is as follows: 1- 2 weeks old 8-10 ml / only; 3- 4 weeks old 15- 20 ml / only; 5- 6 weeks old 20- 30 ml / only; Weeks of age 30--40 ml / only; 9--10 weeks old 40--50 ml / only. The amount of drinking water in the chicken can also be recorded continuously 3 days before the vaccine is used, and the average value is taken to determine the amount of drinking water. 8 During the hot season, drinking water immunity should be performed in the early morning and should avoid high temperature time. The vaccine diluent should not be exposed to sunlight. 9 The route of vaccination is directly related to the immune effect. Not all vaccines are suitable for drinking water immunization. For example, oil emulsion inactivated seedlings of egg drop syndrome can only be immunized by injection. Immunization with vaccines that are not suitable for drinking water immunization can only lead to immune failure. 10 Drinking water for 2 days before and after drinking water for a total of 5 days (preferably 7-10 days). No drugs or disinfectants that kill the vaccine virus (or bacteria) can be added to the feed. China Agricultural Network Editor
