1. When purchasing a vaccine, first look at the name, approval number, date of manufacture, packaging dose, and production site to comply with the regulations of the "Veterinary Drug Labelling and Specification Management Regulations." Use fresh vaccines produced recently, do not use obsolete or expired Vaccines or vaccines that have not been used up by the last batch of chickens, especially if they have no refrigerators. Vaccine medicines are placed in refrigerators of relatives or neighbors, and they are stored together with frozen fish. They are better protected in professional suppliers' freezers. Because the electricity in rural areas often stops, repeated freezing and thawing will destroy the quality of the vaccine.
2. To accurately calculate the amount of epidemic use, the amount of drinking water should be increased, the amount of eye drops should be smaller than the amount of drinking water, and the diluent should be used strictly as required, such as saline, cold water, well water, or special equipment. The red (Marek) and blue (branch) dilutions should be diluted according to the amount of drinking water and the length of the drinking time to calculate the required dose. In general, control the water before drinking the vaccine, 2 hours in the summer, 3 hours in the winter, so that the chicken has a thirst to drink faster.
3. Chicken vaccines, also known as antigens, are biological products. Can be divided into poisonous seedlings, poisoning seedlings, and virulent vaccines. In the production methods are divided into freeze-dried seedlings and wet seedlings, the preservation method is not the same, freeze-dried vaccines should be kept in a frozen quick-freezer, wet vaccines, also known as liquid vaccines, to be stored at 0 °C ~ 8 °C In the freezer, because the refrigeration equipment in the countryside is incomplete, most chicken farmers are not rich and have no refrigerators. Therefore, they must use them nowadays, especially during the summer, they must add ice to the vaccine when they get home. And it is best to drink ice water in drinking vaccine, but also to avoid direct sunlight in order to ensure the effect.
4. Strictly control the dosage. When injecting oil seedlings, the amount of injections must be strictly controlled. The amount of vaccine injected is rather large and insignificant. The volume of the chicken body will be exacerbated by the amount of the assembly, and small amounts will not cause immunity.
5. Pay attention to the method of dilution; the lid of freeze-dried seedlings is a high-pressure lid. Dilution method is to use a syringe to slowly inject five milliliters of diluent into the bottle. After the bottle is dissolved, open the stopper and pour it into the water. This avoids the sudden opening of the vacuum freeze-dried seedling bottle cap, and the pressure in the bottle will suddenly increase, causing some viruses to be impacted and inactivated.
