In the production of large-scale chickens, nasal drops, eye drops and intramuscular injections are used for the vaccines, which are laborious, difficult to handle, and have poor immune effects. After years of exploring and summarizing the experience of the majority of chicken farmers, the authors found that feeding chicken Newcastle vaccine in the feed can achieve better immune effects, and the operation method is more simple. 1st immunization: 5 to 10 days of age, use 100 pairs of Newcastle disease II strains of chickens against 100 ml of cold water or physiological saline, dissolve and shake, and mix minced rice or corn flour or chicken granules with 150 grams. Feed them once in the morning. It is immune to 70-100 feathers. 2nd immunization: 25 to 30 days of age, use 100 ml of Newcastle disease II strains for 150 ml of cold boiled water, dissolve and shake well, mix well with 200 g of feed, and feed once in the morning to immunize 50-70 pigeons. . The third immunization: 60 to 90 days of age, using 100 pairs of Newcastle Disease I strains, 250 to 300 ml of cold boiled water, dissolve and mix well, stir in 350 to 400 grams of feed, and feed once in the morning to be immunized. ~ 70 feathers. Matters needing attention: (1) See the name, model number, lot number and expiration date on the vaccine label, and keep the temperature low during transport and storage to prevent vaccine failure. (2) Wet ingredients should be evenly moistened. Medicinal materials can be placed in the trough or sprinkled on plastic sheets laid on the ground for feeding chickens. They should not be sprinkled directly on the ground. (3) The medicine should be protected from sunlight, and it must be done in the morning when the temperature is high. (4) For chickens of different sizes and eating less, they can be fed again on the second day to ensure adequate dosage.
