15 questions that pig farmers care about most
A: At present, the vast majority of vaccines on the market are unofficial vaccines. In view of the situation of pig farm services, it is easy to cause problems such as abortion, death and lameness. Therefore, it is not recommended to keep surviving pigs immunized with "non-blast vaccine".
Answer: Strong acid, alkali, and glutaraldehyde disinfectants that are sensitive to non-pestiviruses are effective. Ultraviolet rays have a disinfecting effect, but the range is relatively small. Generally, it has a certain killing effect in the range of 1 meter.
Answer: It works, but the outdoor disinfection will be affected, especially in rainy and snowy weather. Therefore, it is necessary to strengthen the disinfection in the house to prevent the virus from entering the pigsty.
A: There are some unofficial vaccines currently on the market. There is no national approval for illegal vaccines. The effect is difficult to say, but the risks are very high and there is no guarantee for the safety of pig farms.
A: The research direction of gene-deleted vaccines has been proven to be the best research direction for non-blast vaccines. Any vaccine has risks. Teacher Liu just introduced the problems that may be caused by using the vaccine in advance, rather than saying that the vaccine is not good.
Answer: First of all, we must understand the causes of diarrhea, such as low ambient temperature, bacterial infection and viral disease (diarrhea). It is necessary to control the temperature in the piggery (18-25 ℃). Antibiotics should be used for diarrhea sows with bacterial infection. The effect should be can. For viral diarrhea, vaccine health care needs to be done well in advance, combined with environmental control, to strengthen the isolation of diseased sows to prevent cross-infection.
Answer: You can try to replace the sow. If there is obvious improvement, it may be that the sow milk is poisoned or inflammation. Eliminate some sick and disabled piglets in time. Pay attention to the temperature and humidity control in the pigsty. Do regular environmental disinfection every week.
Answer: Yes, Kang Zhiyuan is usually added at 2 kg / ton feed. In some window periods (estrus, mating, childbirth, weaning, group transfer and immunization), the dosage should be increased. 50 g / head is recommended. When the farm epidemic fluctuates or is under great pressure, it is also necessary to increase the use.
Answer: It may be caused by indigestion, or it may be caused by some viral diseases (pseudomania, blue ear, etc.).
Answer: The acidifier can be used in combination with the detected pH value. It is recommended that the product (purified water 3.9) be added at 1: 3000 and adjusted to a range of 3.6-3.8 with a ph meter test. The drinking water situation is different in different regions, and the dilution ratio of the acidifier should be adjusted according to the actual situation.
A: No cases or experimental reports of non-pesticidal transmission over the air have been found for the time being. When the piggery is poorly ventilated and has a lot of dust, the non-blast virus is also not transmitted through short-distance contact with the dust. Therefore, the farm should control the environment and ventilate.
Answer: Yes. Acidifiers should be added to all water used in pig farms, including drinking water, flushing water, water sources (water towers), etc.
Answer: For diseased pigs, they need to be fully disinfected before being harmless (involving tooth extraction requirements). For non-diseased pigs, regularly use potassium persulfate to disinfect pigs. It is recommended that they be disinfected 2-3 times a week.
Answer: Once every 2-3 days, it is recommended to use a highly effective, safe and non-toxic disinfectant, such as products whose main ingredient is potassium persulfate.
Answer: Disinfection is required, and the silent period is generally 21 days (non-pestic virus incubation period).
