1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, containing no gelatin from animals, invented and produced in China. Getting rid of gelatin from varicella vaccine can significantly decrease the ratio of anaphylaxis incidence .
2.Long validity period by good stability. The first approved varicella vaccine with 36 months of validity period in the world. Adopting BH-2 stabilizer with own IP rights (Chinese patent granted No.: ZL200910138411.6, International patent application No.: PCT/CN2009/001405) greatly enhances the stability of the product and ensures the validity period for 36 months under the storage condition.

1 Increase piggery temperature
One is an open-type pig house covered with plastic film. It is best to cover the double-layer plastic film, although the cost is higher than the single-layer plastic film coverage, but the insulation effect is better. This approach is suitable for fat and non-lactating sows. The second is the boiler-type heating supply in closed pig-raising workshops. The third is the open-type heating heating and plastic film covering the piggery. The fourth is heating heating plus electric heater, suitable for nursing sows.
2 The outer wall should be thick and tight
The back wall, gable, and front wall of the pig house should be increased in the winter. The crop stalks can be stacked and the adobe can be temporarily built. It is best to thicken the outer walls when the pig house is built.
3 The ground should be dry
Fecal sewage should be promptly removed and cleaned. In order to facilitate drying, the piggery should be made of concrete floor.
4 Addition of bedplates
In the piggy stage, where conditions permit, it is best to use warm sheets such as wood boards, bamboo boards, thick fiber boards, etc., and without preconditions, cement precast boards can be laid.
5 Improve drinking water temperature
If conditions allow, cold water can be warmed and then the pigs can be drunk or deep groundwater can be fed to pigs.
6 Increase the number of feeds
The purpose of increasing the number of feeds is to relatively increase the feed intake to compensate for the weight loss caused by the body fat and intramuscular metabolism of heat due to low temperature. Where conditions permit, it is best to take free food. Feeding can be added at night in places where feeding is scheduled.
7 Improve feed energy levels
It can increase about 10% on the basis of the original feed energy level. The big pigs are low and the pigs are high. Piglets can be supplemented with high-energy feeds for fats and oils. Big pigs can increase the amount of common energy feeds such as corn in batches.
8 Increase lighting area
The open-type pig house should have a large open area in order to prepare the winter covered plastic film for easy lighting. Closed pig houses are to be reserved in the south wall and the roof to prepare for the installation of glass in winter.
icacy. It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75% in vaccination. Of all released batches of Varicella Vaccine from BCHT, the titers are not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
In winter, the temperature is low, and the piggery must take warm and warming measures. In addition to these measures, we must also pay attention to keep the ground dry, maintain proper ventilation, and the temperature of drinking water should be properly increased.
