Chinese scientific research institutes initiated technology research on yak embryo transfer to protect and develop rare species of yaks on the Tibetan Plateau. The Tibet Yak Research and Development Center and the Kunming Institute of Zoology, Chinese Academy of Sciences cooperated to carry out this research. Dr. Ji Qiumei, who is responsible for the research work, said that the yak embryo transfer technology is still a blank field. Some international scientific research institutions have successively carried out research on yak embryo transfer, but no breakthrough has been achieved so far. The Yak embryo transfer technology is an advanced biotechnology. It is based on a yak as a recipient cow and transplants another embryo of a healthy female yak with no reproductive disease or infectious disease carefully selected by scientific researchers. Recipient cows in the uterus, "abdominal child" to develop a good variety. Embryo transfer technology has been widely used in the breeding of cattle, sheep and other livestock, but it is still a blank in the calf field. Dr. Ji Qiumei said that the offspring produced by embryo transfer are superior in genetic quality, and their quality and value are far higher than those of improved hybrids. At the same time, embryo transfer is also conducive to the preservation of species resources and the promotion of the establishment of elite gene pools and improved varieties.
Medical Mask is a kind of hygiene product. It is generally worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances. It is made of gauze or paper and other materials. .
The Disposable Medical Mask has a certain filtering effect on the air entering the lungs. Wearing a mask has a very good effect when working in a polluted environment such as dust when respiratory infectious diseases are prevalent. Masks can be divided into 3 Ply Disposable Masks and air-supplied masks.
