For the farmers, it is common for the pigs to give the pigs a hand, because the usual vaccination of the piglets and the injection of drugs into the sick pigs are basically self-employed, so that the veterinarian can charge for the injections, and the cost of breeding can be saved by himself. However, after all, farmers have not received systematic veterinary training, and there will inevitably be some misunderstandings. See if you are recruited?
1, the needle is too short and too thick
When injecting a pig, the farmer sometimes chooses a needle that is not suitable for the needle. The use of an inappropriate needle will affect the injection effect and affect the efficacy. So how do you choose the right needle? Select the appropriate needle by the size and size of the pig. For example, the pig should use the 9th and 20mm short needles; the middle pig should use the 12th and 25th to 30mm needles; the sow and the big pig must use the 16th and 38th. A 44 mm thick needle.
2, the vaccine injection site is always in the same position
Generally, the injection of the animal will be selected subcutaneously after the neck, but some pig farmers will vaccinate the pig every time after the neck, causing swelling in the posterior part of the neck, and the swelling can no longer be injected, otherwise it will produce A phenomenon that cannot be absorbed. In addition to the neck, you can choose the hip or post-femoral injection.
3, injection of swine fever vaccine does not change the needle
A pig and a needle should be given when injecting the swine fever vaccine to avoid vaccine contamination and cross infection. Therefore, the farmer must change the needle after injecting a vaccine into a pig.
4, the injection is not strict, resulting in abscess
Before the injection, the injection area should be disinfected with alcohol, which is justified by people. Because the disinfection awareness of the farmers is not enough, many pig farms have cases of abscesses caused by poor injection and disinfection. In this case, the pus should be cut in time, and the pus should be buried in a plastic bag to avoid contamination of the ground.
5, the vaccine is too shallow
Vaccination, especially oil seed injection, will only be injected into the fat layer if the injection site is too shallow, resulting in the pig not being able to absorb the vaccine, resulting in immune failure.
6, the same syringe uses a variety of drugs during treatment
Every farmer wants to save on farming costs during the farming process. However, it is impossible to save in some areas, and the money saved in the future will cause more trouble. For example, in the case of injections, some farmers have to save money and effort to mix drugs that they think can be mixed in a syringe, so that injection is not only unsafe, but also causes adverse reactions in pigs. Therefore, the farmer should still inject according to the instructions for use when taking the injection.
It is a good thing for farmers to vaccinate pigs by hand. Once they can get a general understanding of the health status of the pigs, they will be able to accumulate medication experience, which is equivalent to the upper half of the barefoot doctor. But don't neglect the details in order to save time and effort, otherwise it may cause losses due to misunderstandings in these details.
