Core Tip: This article will share the four measures in the pig farm to improve the maternal antibody in the sow's milk for reference by the farmers. See below for details.
Netcom: There are four main measures to increase maternal antibodies in milk.
First: sows instead of piglets suffer from vaccination
“Pregnant sows are not suitable for vaccination? How to fight?†Many veterinarians and experts recommend less vaccine for this topic, and Teacher Zhu gives his opinion: “Sows can fight when they are pregnant. The vaccine should be arranged as much as possible during the sow's pregnancy." He also pointed out: "The vast majority of vaccines are safe for pregnant sows during pregnancy." At the same time, an example of the human flu that occurred in previous years confirmed that pregnant women It is safe to take a flu shot, and it is safe to vaccinate pregnant sows. Under this premise, immunization of sows in late pregnancy can trigger high levels of antibody production. When adjacent to delivery, a large amount of antibodies enter the milk at a concentration that is more than three times the normal serum antibody titer. This is sufficient to ensure that piglets receive high levels of maternal antibodies from colostrum to prevent early infection.
Second: true seedlings, real hit, really effective
Zhen Miao: We usually ensure that the vaccine is effective before the vaccine bottle cap is opened before the vaccine is administered. It is recommended that some vaccines should be stored in the refrigerator in principle. It is suitable to store at 2-8 °C, but it is necessary to remind everyone that the temperature near the bottom of the refrigerator may be 0 ° C or even 1-2 ° C below zero, then 2-8 ° C is required. The saved vaccine will lose its effect. From here, I also tell you that the details of the behavior will determine the success or failure of your pig. In normal times, in daily pig production, have you ever encountered this pig disease and other pigs did not send it? Are you concerned about these abnormal factors?
Really hit: Under the premise of ensuring an effective vaccine, hit the effective part, we need to use the appropriate needle to inject into the muscle according to the size of the pig.
Really effective: When immunizing, you should choose when the pigs have a good mental state, especially when they are exempt. For pigs with poor mental status, the immune system can be supplemented to enhance the body's resistance to achieve the best results.
Third: the farm adopts strict bio-safety measures
The risk analysis of the epidemic from the off-site to the intra-field transmission route is as follows:
Fourth: disease-resistant nutrition replaces antibiotics for health care
Teacher Zhu proposed to replace the sows with prebiotics and postpartum antibiotics with disease-resistant nutrition (immune nutrition, reproductive nutrition, enteral nutrition), and to meet the special nutrition (resistance nutrition) of sows during reproductive stress. Additional demand, on the other hand, provides adequate maternal immunity to piglets through sow milk. Nowadays, many farmers like to use antibiotics for health care, which is very wrong. Denmark is the country that bans animals from using antibiotic feed (additives). From 1995 to now, it has introduced more and more strict antibiotic bans for animals, so that animals will gradually move away from antibiotics. A series of hazards.
