Key points of Management of Pig Conservation

1. Suckling piglets

Ensure that each piglet can eat enough colostrum after birth, which can improve immunity, enhance resistance and reduce the incidence of disease.

The temperature in the lying area of newborn piglets required 35-37 ℃, then decreased by 2-3 ℃ per week, and the temperature in the active area was 20-24 ℃.

On the second day after birth, the piglets were injected with high-quality iron agent 100 mg and 150 mg iron. According to the actual situation of this field, 0.5 ml of long-acting oxytetracycline can be injected 2-3 days before the beginning of diarrhea in piglets, once more every 5-7 days, and 1 ml / head 1 day before weaning to prevent diarrhea.

The nutritional requirements of 3-week-old piglets for breast milk are 97% and 37% at the age of 4 weeks. Early training of piglets to start feeding can alleviate the effects of weaning stress. Piglets should be induced to eat at the age of 3-5 days, and a little high-quality trough material should be sprinkled in the trough. The trough must be cleaned and sterilized twice a day.

2. Feeding in the first 2 weeks after weaning

Piglets must be fed a high-energy, high-quality protein, digestible, palatable and nutritious diet in the first 2 weeks after weaning.

Weaning piglets suddenly change from breast milk to solid feed, which will cause great stress. at this time, attention should be paid to the form of feed, which can be mixed with wet mixture (2 parts of water and 1 part of feed). High-quality suckling pig milk powder, glucose, multi-vitamins and so on can be added to the feed, and a small amount of multiple meals can be fed 5 to 6 times a day, which can alleviate weaning stress, increase piglets' feed intake and obtain greater weight gain.

3. Nursery

The local temperature of newly weaned piglets was generally required to be 30 ℃, then decreased by 3 ℃ per week to 22 ℃ per week. Heat preservation of weaned piglets can reduce cold stress, thereby reducing the incidence of post-weaning diarrhea and other diseases caused by cold. In the heat preservation, we should try to use heat sources that have no impact on the environment of the nursery, such as infrared insulation lights, electric hot plates, plumbing and other insulation equipment, and try not to use heat sources such as coal that have a great impact on air quality.

Ensure that each nursery pig has a lying space of 0.3 to 0.4 square meters.

Strengthen ventilation and reduce the concentration of harmful gases such as ammonia and carbon dioxide in the house, so as to reduce the stimulation to the respiratory tract of piglets, thus reducing the occurrence of respiratory diseases.

Clean the feces frequently, reduce the flushing times as much as possible, and control the air humidity in the house at 60%-70%; excessive humidity will cause diarrhea and skin diseases in piglets; too low humidity will lead to an increase in dust in the house and cause respiratory diseases.

4. Eliminate remnant pigs in time

The growth of remnant pigs is slow, even if they survive, it takes a long time and more feed to raise them out of the pen, and the loss outweighs the gain.

Residual pigs grow slowly, mostly sick pigs, the more residual pigs, the more pathogenic microorganisms in the nursery, the more susceptible to infection of healthy pigs, feeding, treatment in the process to take up a lot of time. It is found that the residual pigs will be eliminated in time.

5. Drug health care and deworming

In the first week, piglets were added with 60 grams of Zhiyuan net, 500 grams of high-quality multivitamins, 1 kilogram of glucose or 300 grams of Jiakang (mainly florfenicol), 500 grams of multivitamins and 1 kilogram of glucose per ton of water. can effectively prevent the occurrence of respiratory diseases.

During the period of vaccination, adding high-quality multivitamins to the diet can relieve stress to a certain extent.

About 3 weeks after weaning, parasites in and out of the body should be expelled, and highly effective deworming drugs such as "kenvermectin" (mainly ivermectin) and "Tongming" (mainly Doramectin) can be selected.

6. Standardize the immunization procedure

Vaccination stress can not only be shown in the injection, but also significantly reduce the feed intake of piglets, affect the development of their immune system, too much vaccine injection will even cause immunosuppression, so vaccination should be reduced as far as possible in the nursing home.

7. Strict disinfection

After the pigs in the pen are turned out, all utensils, barns and equipment surfaces are sprayed and fully infiltrated and soaked for a period of time; use high-pressure cleaners to thoroughly rinse the floor, high beds, drinking fountains, troughs, etc. After all the utensils are dry, a disinfectant with high efficiency, broad spectrum and low irritation is selected to spray the empty column completely. After 2-3 days, each place is disinfected once with flame, and then transferred to weaned piglets after being left vacant for 1 week.

8. Divide the area

According to the principle of "all in and all out", a nursery can be divided into several areas, each area is a separate space, and the piglets in one area are transferred to piglets weaned in the same week, and the piglets in this area are completely transferred out. After being thoroughly sterilized and left vacant for a week, another batch of piglets will be added.
