1、 Nasal drops, eye drops for immunity
Nasal drip and eye drop immunization are used for immunization of 5-7 day old chicks, and the vaccine used is the chicken Newcastle disease and infectious bronchitis combined freeze-dried vaccine (usually called Xinzhi H120), which is used to prevent chicken Newcastle disease and infectious bronchitis. There are two types of chicken Newcastle disease and transmission of the two line vaccine. One is the new line H120, which is suitable for 7-day-old chicks, and the other is the new line H52, which is suitable for immunization in 19-20-day-old chickens.
2、 Drip immunity
Drip immunization is used for immunization of 13 day old chicks, with a total of 1.5 doses administered. The vaccine is a trivalent freeze-dried vaccine for the prevention of chicken infectious bursal disease. Each company's bursal vaccine can be divided into attenuated vaccine and poisoned vaccine. The attenuated vaccine has weaker virulence and is suitable for 13 day old chicks, while the poisoned vaccine has slightly stronger virulence and is suitable for 24-25 day old bursal vaccination.
Operation method: Hold the dropper with your right hand, with the dropper head facing downwards and tilted at an angle of approximately 45 degrees. Do not shake it randomly or frequently pick up and put down the dropper to avoid affecting the droplet size. Pick up the chick with your left thumb and index finger, hold the chick's mouth (corner of the mouth) with your left thumb and index finger, and fix it with your middle finger, ring finger, and little finger. Rub open the beak of the chick with your thumb and index finger, and drip the vaccine solution into the chick's mouth facing upwards.
3、 Subcutaneous injection in the neck
Subcutaneous injection of immunization in the neck is used for immunization of 1920 day old chickens. The vaccine is H9 inactivated vaccine for Newcastle disease and influenza, with a dose of 0.4 milliliters per chicken, used for prevention of Newcastle disease and influenza. Inactivated vaccines, also known as oil vaccines or oil emulsion vaccines, are the same type of vaccine. The commonly used oilseeds for chickens include Newcastle disease, H9 inactivated vaccine (commonly known as Xinliu H9 vaccine), and H5 avian influenza.
The difference between the two types of oil seedlings is that the H9 dual vaccine is used to prevent Newcastle disease and influenza caused by the H9 strain, while the H5 strain is used to prevent influenza caused by the H5 strain. Injecting only H9 or H5 cannot prevent both types of influenza at the same time. The virulence of H9 strain of influenza is not as strong as that of H5 strain, and H5 strain is the most harmful avian influenza. Therefore, the prevention of H5 strain of influenza is a top priority for the country.
Operation method: Hold the lower part of the chick's head with your left thumb and index finger. Rub up the skin on the neck of the chick, forming a small nest between the thumb, index finger, and the skin in the middle of the chick's head. This nest is the injection site, and the middle finger, ring finger, and little finger hold the chick in place. Insert the needle into the skin behind the top of the chick's head, being careful not to pierce bones or the skin. When the vaccine is injected into the chick's skin normally, there will be a noticeable sensation in the thumb and index finger.
