Four Misunderstandings in pig health care

When we raise pigs again, we must do a good job in pig health care. If we don't do a good job in pig health care, or if we don't do a good job in pig health care, then our pig farms are likely to have large-scale diseases, and even bring us significant economic losses. So how should we do a good job of pig health care in the process of daily pig breeding? How can we avoid large-scale disease outbreak in pig health care and bring us economic losses? This has something to do with our mistakes in health care.
Myth 1: health care only in an extraordinary period
Health care is to induce and improve the internal environment of livestock, including improving immunity and purifying viruses and bacteria in the body, which should work normally. If the pig is ill, it can be treated as if it were mended after death. Therefore, we should do a good job in health care in order to prevent the outbreak of some malignant diseases and reduce unnecessary economic losses.
Mistake 2: choosing medicine for health care and not paying attention to drug resistance
We all know that vaccination is good for health care, but it doesn't mean that if we do it, we won't get sick 100% of the time. We will only reduce the chance of getting sick relatively. Even if we get sick or get medical treatment, we won't die in a large area. Therefore, under the premise of vaccine health care, we need to use medicine for health care. In the choice of drugs, we need to choose those without drug resistance, because the commonly used drugs have a certain amount of accumulation in the body, which is very simple to produce drug resistance. If we still use them, we often add cost and fail to achieve health care.
Mistake 3: only add antibiotics and no Immunoenhancers
The ultimate purpose of health care is to enhance the immunity, resistance and self-protection of pigs, and then ensure their healthy growth. At present, the main problem of swine is immunosuppression, especially the low immune function caused by the damage of immune organs (such as spleen, bone marrow, lymph nodes, etc.). If we don't solve the problem from these aspects, just add antibiotics to health care, it will get worse and worse. If there is any disturbance, it will die.
Misunderstanding 4. Pay no attention to the two key links of sows and piglets
Before sow breeding, 20 days, 70 days, 90-100 days after conception, prenatal and postpartum are the key links of health care. If health care is done well in these key stages, the reproductive function of sows will be greatly improved, and the survival rate of piglets will be high. Three injections of health care should be done three days, seven days and twenty-one days after the birth of piglets, and the health care work should be done well after weaning or after the purchase of piglets into the pen, which will avoid the occurrence of diarrhea and respiratory diseases, greatly improving the survival rate and the regularity of the market.
It is very necessary for us to do a good job in the health care of the pig population, because we will definitely be exposed to some pathogens in the process of pig breeding. If our pigs do not have enough resistance, they will get sick. If it is a contagious disease, it will cause our whole pig farm to suffer certain problems. Therefore, we are using pig breeding equipment to raise pigs At that time, we must not forget to do a good job in health care for the pigs.
