Chicken laying period vaccine injection method
First, the site of injection of vaccine should be selected in the subcutaneous or superficial pectoral muscle injection in the neck is not recommended in the leg muscle injection, especially the injection of bacterial seedlings. The correct method of subcutaneous injection in the neck is as follows: one person holds the chicken and the other person is responsible for the injection. After injection, the skin of the neck of the chicken was pinched with the thumb and forefinger to separate the skin from the neck muscles, and the syringe needle was injected subcutaneously between the thumb and the index finger at less than 30 degrees. Oilseeds after injection should be distributed between the neck muscles and the skin. In the pectoral muscle injection, a short needle 7-9 should be used. The needle and the injection site should be at an angle of 30. At the upper 1/3 of the chest, the pectoral muscles should be pierced in the direction of the back and cannot be pierced vertically.
Second, the oil seedlings should be shaken before immunization, pay attention to pre-temperature pre-temperature method: 4-5 hours before seedling injection, remove the oil seedlings and put it in warm water, so that the oil seedling temperature as close to the chicken's body temperature when the injection.
Third, when the seedlings should be taken care of the chickens, the chicken movements can not be rude. The majority of chickens after the emergence of seedlings after the emergence of the egg rate fell and the catching chicken movements are too rude. However, egg breeder chickens often perform artificial insemination because of their catching chickens. Their impact on egg production rate is small after injection of oil seedlings.
4. During the injection of seedlings, drugs may be added to relieve stress. Two to two thousandths of oxytetracycline and drinking water may be added to the feed for 2-3 days before and after the seedling injection to relieve the seedling stress. Adding an immune booster in drinking water to improve vaccine protection.
Fifth, laying hens should be selected for oil injection at the right time for the normal high-yield chickens to focus on egg production in the morning, the number of eggs produced in the morning accounted for more than 80% of eggs produced throughout the day. In the afternoon, the sheds are dark and it is not easy to cause chicken flocking. Therefore, it is very necessary to choose injections in the afternoon, especially after 4 o'clock. If you inject oil seedlings in the morning, disrupting the normal egg production patterns of chickens, it is easy to cause symptoms such as abdominal egg and yolk peritonitis.
6. When an infectious disease occurs in a neighboring chicken group, emergency immunization of the chicken group should be conducted in the order of “healthy chickens → presumed healthy chickens → sick chickensâ€. When the disease exists in the flock, oil seedlings should be avoided. If necessary, vaccination should be conducted under the guidance of a veterinarian.
After paying attention to the above issues, injection of oil seedlings during the laying period has no significant effect on the egg production rate of the flock. Even if the egg production rate drops after injection, the rate will not be large.
