How to vaccinate black bone chicken

Vaccination method The inoculation method of intranasal injection of the vaccine into the body through the nasal drops is suitable for the vaccination of Newcastle disease vaccine and infectious bronchitis vaccine and infectious laryngotracheitis attenuated vaccine. The method of operation is to dilute a certain dose of the vaccine in sterile saline, shake well, and then inhale the liquid with a dropper, and instill a drop from the nostril of each chicken.

Wing Measure This method is suitable for inoculation of fowlpox vaccine. The method of operation is to dilute the vaccine by 50 times with cold boiled water, distilled water, or physiological saline. Dip the vaccine with an inoculation needle or a clean pen tip, and prick the vaccine into the wing of the chicken wing without a blood vessel.

Dripping or rubbing the anal method This method is suitable for the vaccination of infectious laryngotracheitis or bursa vaccine. The method of operation is to dilute a certain dose of the vaccine in sterile saline, and then put the chicken upside down, squeeze the waist by hand to make the anal mucosa come out, drop the vaccine by one drop, or use a cotton ball to take the vaccine and wipe it twice.

Subcutaneous injection This method is commonly used for the inoculation of Marek's disease vaccines and oil emulsions. The method of operation is to dilute a certain dose of the vaccine in a dedicated diluent and inoculate it subcutaneously on the back of the neck.

Intramuscular injection This method is suitable for live ND vaccine, inactivated vaccine or infectious bronchitis, bird flu inactivated seed oil emulsion vaccination. The method of operation is to inject 1 ml or 0.5 ml per chicken into the gauze or muscle of the chest and the muscles of the leg in the glabrous part of the shoulder.

Drinking water immunization method If the breeding quantity is large, it takes time and effort to inoculate only one by one, and disturbs the flock and affects the weight gain. The drinking water immunization method with the best effect can be used. For example, Newcastle disease virus II, IV vaccination can use this method. The method of operation is to first calculate the number of vaccines needed for the entire group, and then dilute them with cool boiled water to allow chickens to drink freely. Water must be stopped for 2 hours before immunization and antiviral drugs should be discontinued.

Spray immunization method This method is suitable for semi-mechanized and mechanized chicken farms, which saves manpower and does not disturb the flock. It does not affect egg production and weight gain, and has good immunity. However, spray immunization can only be used for chickens over 60 days of age. This method is used for chickens up to 60 days of age, which can easily cause mycoplasma disease and other upper respiratory diseases.

Immunity Precautions It is best to use sterile distilled water to immunize with drinking water. Before immunization, stop using water for 2 hours to 3 hours. Do not use chlorine-sterilized water. If using tap water, allow it to stand for 2 hours. If you use suspected sterile distilled water, then 50 grams of skimmed milk powder should be added to every 10 liters of water; the vaccine-containing water should be consumed within 1 hour.

When injecting the oil emulsion inactivated vaccine, pinch the skin at the junction of the lower third of the neck and the upper 2/3 of the neck with the left hand. The needle is inserted from the top down. After the vaccine is injected, squeeze the needle into the mouth to avoid it. With the outflow of the vaccine, do not raise the needle upwards to avoid swelling.

In order to reduce the stress on chickens during immunization, electrodialysis multidimensional and other anti-stress drugs can be given 2 days before immunization, and vitamin K3 and vitamin C can be administered at the time of dehydration. For oil emulsion inactivated vaccines, the health status of the flock should be known in detail before use. Unhealthy flocks cannot use the vaccine and are only suitable for healthy flock immunity. The temperature of the vaccine should be raised to room temperature before use, and shake well before use and during use.
