More and more poultry farmers are now buy battery chicken cage systems to raise layers. Cages are better and harder to vaccinate and a lot of stress for the chickens. If it is serious, it will affect the laying rate of chickens. When chickens in the laying period have to be vaccinated, the stress should be reduced from the following aspects.
- The vaccine should be injected subcutaneously in the neck (lower 1/3) or in the superficial pectoral muscle. Injections into the leg muscles, especially bacterial vaccines, are not recommended. Neck subcutaneous correct injection method is: one person is responsible for chicken, another person is responsible for injection.
- Shake oil vaccine well and pay attention to pre-temperature before immunization. In the autumn and winter before injection of oil seedlings, it is necessary to pretemperature. Pre-temperature method: 4-5 hours before the injection, take out the oil seedlings and put them in warm water (37-40℃), so that the temperature of the oil seedlings as close as possible to the body temperature of the chicken before injection.
- When seeding, the chickens in the automatic chicken raising equipment should be handled gently. Don’t be rude when you catch a chicken. In most flocks, the decrease in egg production after seeding is related to the rough scratching. However, the effect of oil injection on laying rate of egg-breeders is less because of artificial insemination.
- Drugs can be added to relieve stress response during vaccine injection. 2 ‰ oxytetracycline in feed and aminovita in drinking water can be added 2-3 days before and after seeding to relieve the stress of seeding. Add an immunobooster to drinking water to improve vaccine protection.
- The oil injection of laying hens should be carried out at the appropriate time. Due to the normal high production of chicken egg production in the morning. The number of eggs produced in the morning accounts for more than 80% of the eggs produced throughout the day. Afternoon chicken house light is darker, not easy to cause chicken group fried group. Therefore, the choice of injection in the afternoon, especially after 4 o ‘clock is very necessary. If the oil vaccine is injected in the morning, the normal egg production rules of the chicken flock are disrupted, and it is easy to cause symptoms such as egg in the abdomen and egg yolk peritonitis.
- When infectious diseases occur in nearby flocks, flocks should be vaccinated urgently. Inoculation was carried out in the sequence of healthy chickens, assumed healthy chickens, and sick chickens. Oil vaccination should be avoided when disease is present in the flock and should be carried out under the guidance of a veterinarian if necessary.
After paying attention to the above problems, injection of oil seedlings during laying period had no obvious effect on laying rate of chickens. Even after seeding, the decrease in egg production was not significant. The above is the chicken farm equipment suppliers for you to share the use of battery chicken cages for chicken injection vaccine methods. Hope to help poultry farmers
