Management technology of new piglets

New pigs are affected by a variety of stress factors, such as transport stress, environmental changes, feed changes, etc., which cause mental and physical pressure on young pigs, resulting in gastrointestinal dysfunction and endocrine disorders, which often cause diarrhea, edema and other diseases in young pigs, resulting in dysplasia, slow weight gain and increased mortality.

The preparation work before entering the pig

First of all, it is necessary to understand the background of the pigs purchased, whether there is an epidemic or in a state of sub-health, and whether to do a good job of vaccination, so as to avoid buying pigs with disease. Secondly, in the process of transportation, we should pay attention to keep out the cold and the wind, drink water or feed a small amount of feed in the middle of long-distance transportation, and pay attention to handling pigs and catching pigs gently to avoid pig injury. Keep the temperature of the empty enclosure at 20 ℃ ~ 24 ℃ before entering the pen, so that the pig can adapt to the new good environment as soon as possible.

Group and density

The group should be based on the principle of similar body weight to avoid the phenomenon of bullying, bullying and bullying caused by excessive differences. The best density is to raise 1 pig per square meter, and 8 to 10 pigs per column to avoid excessive density and population size. Adequate sinks and sinks should be prepared or free feeding tanks and drinking fountains should be used.

Measures to avoid stress reaction

Drinking water: after entering the fence, pigs should first drink 15 ℃ ~ 20 ℃ of clean warm water. Electrolytic multivitamin, vitamin C and glucose powder are added to the water to synthesize anti-stress drugs.

Feeding: in line with the principle of less frequent feeding and gradual transition, the pigs should be fed 5 times 6 times a day at the beginning, 4 times a day after 7 days, regularly, and select high-grade pig feed with comprehensive nutrition and good digestibility. It can reduce the stress caused by feed changes to a minimum and promote the normal development of digestive and immune organs of pigs.

Environment: to create a warm, dry, clean and comfortable living environment for pigs, adjust the temperature in the house, keep the enclosure hygienic and clean, do a good job of ventilation, ensure fresh air in the house, improve the air quality of the pig house, and reduce the concentration of ammonia.

Carefully observe the dynamics of pigs

The new pigs should do a good job of "three positioning", adjust their feeding, sleeping, defecation and urine habits, and do a good job of pig positioning, which will bring the effect of once and for all for the future management. The mental, feeding and health status of pigs should be observed at any time, and the abnormal situation should be solved in time.

Do a good job of immunization

After over-feeding for 5-7 days, the stress state of the pigs was alleviated, and all kinds of vaccinations were needed, including classical swine fever, swine erysipelas, porcine lung disease and paratyphoid swine paratyphoid. If you know that the other party has been vaccinated against four kinds of diseases when buying pigs, it is suggested that the classical swine fever vaccine should be injected again. In addition, according to the situation, we can increase the immunization projects of foot-and-mouth disease vaccine and swine edema disease vaccine, and do a good job in the prevention and treatment of pig disease.
