Pigs weigh eight times to keep safe in winter

Wind protection

In the winter, the pig house must block wind tunnels, hang straw curtains, and paste windows to prevent rat holes, cracks, gaps, and broken ceilings in the circle from blowing into “draft style”. Vents can stay at least 1 meter above the ground.

Anti-moisture

Stow drying is one of the main measures to ensure the health of live pigs. Air is a kind of heat-conducting material, and the more humid it is, the stronger its thermal conductivity is. Cold pigs, crush injuries or even death, the epidemic is also prone to occur. Therefore, the ring must be matted to ensure dryness, and attention should be paid to training pigs to defecate urine and have a dry place.

Low temperature

The optimum temperature for growing pigs is 15°C~25°C. Normal growth temperature should generally be above 8°C. In order to ensure the normal growth and development of pigs, the best method is to adopt a warm greenhouse for raising, that is to use a thick plastic film to cover the top of the surrounding, cover should have about 30 degrees of slope, easy Lighting, ventilating at high noon area should be ventilated and ventilated, and should be promptly removed after snowing.

Cold food

In winter, pigs eat nothing more than to protect themselves from the cold and increase their weight. Sows need to protect their normal growth and development of the fetus. Increase its cold power. When feeding the mixed feed, it is best to feed raw food dry. When mixing with a small amount of water, the water temperature should be around 25°C. To take a balanced approach, drink should be warm, and less to add ground, cold and antifreeze.

Prevent feeding

Feeding pigs should be done with stable quality and stable feeding time. The ingredients should be based on different production performances and different growth stages. Avoid sudden changes in quality. If there are changes in the material, increase the amount and change the feeding time.

Cold drinks

Pigs have a great demand for water, and the demand for water is very important. If there is no water in the circle, the pig will eat snow, eat ice, and drink urine, which will inevitably cause digestive diseases or other diseases. Therefore, it is necessary to constantly provide warm and clean drinking water to prevent both the patient and the pig.

Anti-biting

The normal growth of pigs, feeding must be comprehensive nutrition, lack of one or more of the ingredients, not only slow growth, but also may have bite frame "evil", especially the lack of winter green feed, "evil" is more likely to appear Big. Therefore, it is necessary to replenish a variety of vitamins, minerals and trace elements in the feed, and should be divided into small groups and large groups; timely cutting.

Epidemic prevention

Low winter temperatures, dry air, digestive tract diseases of pigs, respiratory diseases, infectious diseases, etc. are very likely to occur. To achieve healthy development of pig production, pigs must always be kept clean, clean and hygienic. Or spray disinfection, pigs need to be vaccinated, and must be equipped with commonly used drugs to achieve early isolation and early treatment.

Influenza Vaccine

Influenza Vaccine, Live, Nasal, Freeze-dried Exclusively authorized by the WHO in China WHO
Influenza Vaccine, Live, Nasal, Freeze-dried is a cooperative project with the WHO, which has been included in Global Action Plan for Influenza Vaccines (GAP)[1]. Hundreds of millions of doses have been used in the world, and Changchun BCHT Biotechnology Co. has the exclusive right of production and

operation in China.

Intranasal spray administration, no injection and no pain


The vaccine is inoculated by nasal spray, equipped with nasal spray device, and only needs to spray once a year in two nostrils to prevent influenza.
Mucosal immunity + Cellular immunity + Humoral immunity

After influenza virus attacks human body, it widely exists in nasal cavity, respiratory tract and other mucosal parts, as well as in body fluids and cells.
Vaccination of Influenza Vaccine, Live, Nasal, Freeze-dried can quickly stimulate the triple immune response of human body, and carry out defense
against viruses in different parts:
·Intranasal administration can produce mucosal immunity (IgA antibody), which forms the first immune defense line in the nasal cavity.
·Produce humoral immunity (IgG antibody) to remove influenza virus from body fluids.
·Produce cellular immunity (T cells) to remove influenza virus from cells
3+N More extensive protection
The production strains are recommended and supplied by the WHO every year.
The vaccine can not only effectively resist the vaccine strain, but also produce cross immunity to other subtypes of influenza virus.

Produced with SPF embryonated eggs


The chick embryos for vaccine production comes from SPF (specific pathogen free) chicken flocks, so the risk of exogenous pathogenic microorganism

pollution is excluded.


Free of inactivator, split agent and preservative

High protection and fast antibody production

This is the first influenza vaccine in China that has been evaluated by the protection effect of etiology in clinical stage. The protective effect of phase III
clinical trial is consistent with the literature[2] .
First, the immune barrier was formed in the nasal mucosa after LAIV vaccination. It has been reported that the antibody of nasal mucosa can be
produced in 3 days[3], which greatly shortens the time for vaccine to produce
protective effect.
