major misunderstandings of thorn seed immunity

Autumn is coming, four major misunderstandings of thorn seed immunity

Stabbing immunization is a common method of chicken immunization, and it is often used for immunization of chicken pox and encephalomyelitis. Both of these diseases can be spread through mosquito bites and are also common diseases in autumn.
  According to the analysis of many cases, fowlpox occurred in chickens after the first vaccination, fowl pox occurred after the second vaccination, and encephalitis occurred in chickens after immunization with encephalitis vaccine. Through platform exchanges and on-site investigations, the main problem lies in the implementation of immunization.
  Using traditional puncture needles for immunization is a commonly used method of immunization. In the process of operation, immunized workers face thousands of repetitive operations a day, and there are four key points that are difficult to implement only in place, which are the main reasons for the failure of immunization.
1. Feather dip
  The needle groove touched the feathers when the seed was punctured, and the vaccine in the needle groove was immediately adsorbed to the feathers by the touched feathers, causing immune failure.
2. The needle groove is not full
During the seeding process, when the vaccine liquid in the bottle cannot completely cover the needle, it becomes more difficult for the needle groove to be filled with the liquid medicine. It is necessary to tilt the vaccine bottle and repeatedly dip it, which increases the operation time and The operation is difficult, and a slight negligence will cause inaccurate immunization dose and cause immunization failure.
3. Vaccine overtemperature
During the visit, it was found that most of the immunization personnel held the puncture needle in one hand and the vaccine bottle in the other. The vaccine bottle did not take any heat insulation measures, and the heat in the palm of the hand was quickly transferred to the vaccine, resulting in the vaccine effect. The price drops rapidly, and immunity fails.
4. Vaccine timeout
  When puncturing the seed, if the vaccine liquid in the vaccine bottle is small, the puncture needle will not be easily dipped and the operation will be more difficult. If there is too much vaccine solution, the operation will be a little slower, which will easily cause the diluted vaccine to time out, which will cause immune failure.
  The above four points are the difficulties in the implementation of thorn seed immunization, and they are also the main reasons for the continued disease of immunized chickens.
With the advent of autumn, diseases such as chickenpox and encephalitis have entered the prone season. In order to better prevent and control the occurrence of such diseases, it is recommended to use a continuous seed needle to overcome the above four operational difficulties and effectively improve the success rate of immunization.
  1. The needle of the continuous seed lancet is hidden. When the head on the front screw cap of the seed lancet is completely touched to the immune site, pull the handle and the needle extends to penetrate the immune site to complete the immunization. In this way, the problem of feather dipping in medicine when stabbing seeds is well avoided. In addition, the needle hole is used to replace the needle groove in the location of the seed needle to take the vaccine, which greatly increases the adhesion of the vaccine to the needle, which is conducive to the accuracy of the immunization dose.
  2. The front screw cap of the continuous seed lancet is tapered, and the needle hole is basically at the bottom of the cone. Therefore, as long as the needle is pierced vertically downward during operation, even a small amount of vaccine liquid will be covered with the needle hole, and there is no problem of dissatisfaction.
  3. The hand grip of the continuous seed piercer is the handle part, which is far away from the glass tube storing the vaccine to avoid the shortcomings of the human body temperature being transmitted to the vaccine.
  4. There are 2ml, 3ml, 5ml and other different specifications of the continuous seed piercer. Because the operation is simple, the immunity speed is relatively fast. According to the operating speed, choose to purchase the seed piercer of the corresponding specification, which reduces the problem of vaccine overtime.
  5. As long as the immunizer operates the continuous seed lancet with one hand, the other hand can hold the chickens, saving time and effort.
  Currently, encephalitis is more prevalent in commercial laying hens, and chicken pox is often affected by immune flocks. Autumn is coming and entering the active period of mosquito bite transmission, we must follow the immunization program of the breeding plan to immunize the chicken pox and encephalomyelitis vaccines with continuous seeding devices. 5-7 days after immunization, check the immune site to see if there is scabs to determine the effect of immunity, which can effectively prevent and control the occurrence of such diseases.
