Many people think that artificial hatching pigeons are the same as hatching chickens. In fact, due to differences in the biological characteristics of pigeons and chickens, their hatching techniques are also different. One, Schwing. The temperature of artificial hatching pigeons is higher than that of hatching chickens. Experiments have shown that keeping the incubation temperature between 38.3-38.8°C not only enables the hatching rate to reach the highest, but also the young pigeons have a beautiful appearance and a high rate of breeders. Second, control humidity. The suitable humidity of artificial hatching pigeons is about 10% lower than that of hatching chickens. Humidity throughout the incubation period should be controlled between 50% and 55%. Should pay attention to the humidity can not be too high, especially when a large number of young pigeons out of the shell, should not spray water on the unembedded embryos, such as hatching ducks like water spray humidification, the hatching rate will instead be reduced. Third, the broken egg repair. The hatching rate can be improved by applying unsealed cracked pigeon eggs with latex, egg white, and tape (medical roll type), etc., after being coated or patched. Fourth, statistically azoospermia died. The anasomorphic embryos that have been photographed will be used as an accurate record and the pigeons will be adjusted at any time. This will play a very important role in improving the hatching rate of fertilization. Fifth, outside the box to dry the eggs. The old embryos of pigeons that have been incubated for more than 12 days will be drawn out of the egg compartments. Eggs will be kept outside the incubator. The new hatching eggs in the original box will be hatched as usual. This will greatly increase the hatching rate and the rate of hatching.
Bulk of varicella vaccine,semi-Finished Products.It has good safety with low ratio in adverse reaction. And it has been exported to Bangladesh.
In 2008, BCHT successfully launched its product Varicella Vaccine, Live in China. In the following years, BCHT continuously committed to improving the product and led in 2010 removal of gelatin from adjuvant and extended the vaccine shelf-life up to 36 months which is the longest one in the world in 2011. And it has the following qualities.
