Spring is a period of high incidence of swine diseases. Doing a good job of immunization sampling in spring farms is the key to the safety and epidemic prevention in pig farms in the spring to ensure the safety of pig farms. For this reason, it is recommended that the conditional swine farms be tested twice to four times a year to ensure accurate and safe feeding. If you want to make a scientific assessment of the effectiveness of a pig farm, the first problem is to do effective sampling, which involves the following three aspects: First, what kind of pig? As the saying goes, “The sows are good and they have a good nest. The boars are good and they are good.†It is important to see the importance of breeding boars on a pig farm. The gilts are the source of the farm, and the antibody levels of the gilts and gilts can basically reflect the antibody level of a farm. If conditions are available, pregnant pigs, suckling pigs, weaned sows, and piglets can be sampled at the same time. Samples can also be monitored at various stages of the growth process. Second, how much? The small number of samples collected is not sufficient to represent the entire antibody level of pig farms; there are many sample collections and it is not economical. According to the statistical general rule, when the sampling volume reaches 20, the credibility is 98%, and when it reaches 30, the credibility is 99%. When it reaches 40, the credibility is 99.5%, and when it reaches 50, the credibility is 99.9. %. Therefore, it is recommended that at least 30 samples be collected for each phase. Taking into account the special importance of boars, it is best to sample each boar. Third, how to pick? The healthy pigs are not picking pigs, and it is necessary to ensure that they are randomly sampled to ensure that each parity is balanced. Try to avoid contamination when collecting blood and collect at least 2 ml of blood to ensure that a sufficient amount of serum is detected for detection. The sample marks collected must be clear, the number must be regular, and the order of the samples must be in order to facilitate detection and statistical results. The collected samples should be packed in the insulated box with ice packs and delivered to the laboratory in time. Avoid shaking during transportation to avoid hemolysis. Samples collected must have a detailed description of the pig's age, gestational age, type, final immunization time, and vaccine source.
