How does pig vaccine work after piglets are born?

If you are large-scale farming, the general immunization program is Mycoplasma salvoplasma 14 blue ear + ring, 24 swine fever 3 days of iron supplementation + health injection. If you are a free-range farmer, you will probably get a swine fever.

Birth before colostrum immunization pseudorabies.

7 days Asthma sickness.

14 days streptococcus.

28 days of swine fever.

35 days infectious gastroenteritis.

42 days PRRS.

49 days Streptococcus.

60 days of swine fever.

Foot-and-mouth disease is generally exempted twice a year.

1. Avoid salt: salt can reduce the efficacy of streptomycin, and the sodium ions in salt can make water retain in livestock and poultry, causing edema.

2. Avoid bran: bran contains a large amount of phosphorus and a small amount of calcium, and it is forbidden to feed bran when it is ** livestock and poultry osteomalacia, urinary tract stones, intestinal stones, and rickets.

3. Avoid additives: feed additives contain a variety of minerals such as bone meal, which can reduce the efficacy of oxytetracycline and tetracycline.

4. Avoid cottonseed cake: cottonseed cake can affect the body's absorption of vitamin A, and cottonseed cake should be stopped when preventing and treating vitamin A deficiency in livestock and poultry.

5. Avoid blood meal: blood meal is a feed with high protein content, and should not be taken with blood meal when giving livestock and poultry psoralen, dry banxia, polygonum multiflori, raw land, cooked land and other Chinese herbal medicines. Otherwise, *** will be generated.

6. Avoid beans: soybeans, black beans, red beans and other beans contain minerals such as magnesium, iron, calcium, etc., which can be combined with tetracycline and oxytetracycline to form substances that are difficult to absorb, thereby reducing the efficacy. And mung beans can not only detoxify 100 poisons, but also cure 100 medicines.

How to develop a piglet vaccine immunization schedule.

Piglet immunization program short formDate of birth 1 item Method 2 item Method remarks: 3 days of iron supplementation and pseudo-stabilisation vaccine.

Inject long-acting oxytetracycline every day.

In order to prevent various respiratory and digestive tract diseases, selenium supplementation for 7 days was fed to 2 weeks after weaning, and castration was performed for 7-10 days.

Stress can be minimized, and a second iron supplement can be given 15 days.

21 days intramuscular injection of swine fever common cell seedlings, swine fever spleen drenching seedlings 1 head.

28 days (weaning) weaning does not change circles.

In order to prevent various common diseases, 35 days (one week after weaning) will be transferred to the group at about 9kg, and no feeding. When the piglets are transferred to the nursery with intramuscular pseudo-stabilisation vaccine, the temperature in the house is best between 28---30, and the temperature is too low to affect the growth for 42 days (

One week after transmutation), intramuscular injection of PRRS vaccine to drive out various parasites in and out of the body. 50-65 days of two immunized swine fever ordinary cell seedlings, swine fever spleen drenching seedlings, both can be carried out at the same time, or choose one of the two, depending on the situation. In the 8th and 9th weeks, the piglets were fed concentrate.

Usually the weight can reach 20kg, formula: 25 kg of concentrate, 70 kg of corn, 5 kg of bran, when the pig weighs about 130 kg, the feed is added to the prevention of respiratory diseases.

In order to control various respiratory diseases that often occur at this stage, the large pig concentrate was fed at the 19th-20th week.

Usually the weight can reach 80kg, the formula: 15 kg of concentrate, 70 kg of corn, 15 kg of bran.

Epidemic prevention measures in pig farms play a vital role in the biosecurity of the entire pig farm and the reduction of pig diseases. The epidemic prevention measures commonly adopted by pig farms are as follows:

1. Timely vaccination.

Timely vaccinations are the basis of disease prevention measures on the farm. Pig farms should scientifically vaccinate pigs according to the flow of local diseases, which can prevent the spread of diseases.

2. Regular disinfection.

Pig farms should improve the disinfection facilities in the pig house and regularly disinfect the pig house, which can ensure the safe production of the pig farm and prevent the breeding of diseases. At the same time, pig farms should use automatic feeding lines and other pig raising equipment to ensure the safety of feed and drinking water for fattening pigs.

3. Introduce breeding pig isolation.

Self-farrowing pig farms also need to regularly introduce breeding pigs, pig farms to isolate the introduction of breeding pigs, generally arranged in a separate barn, isolated for a period of time, timely observation of the health status of breeding pigs, no disease occurs, can be put into other pens for feeding.

4. Harmless treatment.

Pig farms need to carry out harmless treatment of sick pigs, dead pigs and other unnatural deaths in time to avoid the spread of pathogens and affect the healthy growth of other pigs.

5. Disease detection.

The disease prevention measures of the pig farm also need to do a good job in the detection of the epidemic in the farm, monitor the disease situation, immune quality, disease purification level and other aspects of the pig farm, and help the pig farm to take effective prevention and control measures in a timely manner, so as to ensure the healthy growth and development of the pig herd.

The above are the disease prevention measures of pig farms. Pig farms need comprehensive epidemic prevention to ensure the safety of pig farm production.

In order to improve the resistance of animals and prevent some incurable diseases, it can be prevented by vaccination. Vaccines are developed specifically for one or more diseases. If all infectious diseases that pigs will be infected with are prevented by raising flowers on the farm, it will consume time and energy, increase the cost of breeding, and will also lead to the competition of vaccines in pigs due to the excessive demand for immunoglobulins, resulting in the failure of some vaccines.

Not only does vaccination cost money to increase the workload of large-scale farms, but it is also a great pressure for pigs. Keeping pigs in a state of stress all the time will cause a sharp decrease in their own resistance, which can easily cause infection. This is why some pig farms still get sick after vaccinating their pigs.

Therefore, it is necessary to focus on vaccination, and pig farms in different regions have different choices of vaccines, so farmers should choose to be vaccinated according to their own conditions.

After the piglet is born, before eating colostrum: the piglet is injected with the swine fever attenuated vaccine immediately after birth, and then eats colostrum two hours later. This vaccine injection is pre-immunization, so the immunity is not strong, and then the immunity is strengthened.

13-day-old piglets: intramuscular injection of multivalent inactivated vaccine for piglet edema disease to prevent piglet edema. 20 day old piglets:

After birth, piglets that have not been injected with attenuated swine fever vaccine can be injected with attenuated swine fever vaccine at 20 days of age. 30-day-old and 50-day-old piglets: intramuscular injection or oral administration of chicine paratyphoid freeze-dried attenuated vaccine will cause symptoms such as anorexia, local swelling, vomiting, increased body temperature, diarrhea and other symptoms in piglets, which will automatically recover after 1-3 days.

Severe piglets can be injected with epinephrine**. Piglets 60 days old: intramuscular injection of swine fever, swine erysipelas and swine pneumonia triple vaccine.

Piglets 70 days old: or intramuscular injection of streptococcus suis lyophilized attenuated vaccine.

The rational use of swine disease vaccine is related to the success or failure of immunization. Read the instructions carefully before vaccination to grasp the correct vaccination time and dosage. Note that antiviral drugs cannot be used for 4 days before or after injection of live virus vaccine, and live virus vaccine and inactivated virus vaccine can be used at the same time.

For example, the swine fever vaccine, including the pulmonary disease vaccine, the oral vaccine for typhoid fever, and the No. 5 vaccine, etc., the breed of pigs is different, the vaccine that needs to be vaccinated is different, and it is necessary to go to a professional hospital for consultation, and iron supplementation is needed after three days of birth, and iron supplementation injection is to be injected.

It is necessary to give the piglet foot-and-mouth vaccine, swine fever vaccine, and diarrhea vaccine These vaccines need to be given when the piglet has just gotten off, so as to enhance the resistance of the piglet and avoid diarrhea.
