Broilers and laying hens have different vaccine immunization procedures. Vaccine immunization programs for free-range chickens and caged chickens are often different. Because the content is relatively complicated, this article is no longer enumerated. Friends in need can follow our WeChat account number. . In this article, we mainly introduce chicken farmers to some of the things that need attention. After summarizing, we have organized the following four aspects.
First of all, to immunize chickens is to pay attention to the timing of the vaccine, the best time is 8 am. The reason for choosing this time for the best vaccine for chickens is because the antibodies in chickens are the weakest, which is very helpful for the rapid and timely production of antibodies.
Second, when raising poultry chickens, chicken farmers generally have to grasp the caps of the vaccine instead of directly grasping the bottom of the vaccine. And after the vaccine is taken out, it should not be diluted immediately, it is better to stay at the outdoor temperature for about 30 minutes before diluting.
Thirdly, chicken farmers should immunize their chickens for the first time. Please use eyedrops or nasal drops. This is because the development of chicken immune organs is imperfect. Newcastle disease vaccine must be activated by the immune organs of chickens. Otherwise, the effect will be. Great discount. If immunized by drinking water, the intestinal tract will be absorbed and excreted. The chicken farmer should be reminded that it is normal if the chickens develop mild respiratory symptoms within 35 days of immunization. This is because the vaccine produces antibodies. If the chicken farmer does not trust, he may be given appropriate anti-inflammatory drugs to treat respiratory diseases.
Fourth, since the bursa of Fabricius is a disease of the intestines, and the vaccine of the bursa is also effective to be absorbed through the intestinal tract. Therefore, it is usually best to use bursins and drinking water for the chicken vaccine method. At the same time, in order to prevent the emergence of related stress symptoms after the immunization of chickens, and in order to achieve better vaccine efficacy, it is best for chicken farmers to add some drugs to prevent chicken colibacillosis after immunizing them with bursa of Bursa.
These are the four things that we need to pay attention to when we give vaccines to chicken farmers and hope to help chicken farmers.
