Deep-sea fish oil, which has always been valued, is expected to be obtained from a pig. The cooperation between the Institute of Animal Husbandry and Veterinary Medicine, Chinese Academy of Agricultural Sciences, the Institute of Biological Engineering, Academy of Military Medical Sciences and Yutian County, Hebei Province, and the Mutuo Breeding Co., Ltd., Yutian County, Hebei Province, successfully developed a "omega-3" fatty acid desaturase gene. Cloned pigs, birth weight 1.15 kg, is currently in good health.
According to Pan Dengke of the Institute of Animal Husbandry and Veterinary Medicine of the Chinese Academy of Agricultural Sciences, molecular biological identification has confirmed that this pig is a transgenic cloned pig.
"Omega-3 polyunsaturated fatty acids" are the main components of "fish oil" and are classified into DHA and EPA. Medical research shows that this type of unsaturated fatty acid, which was previously found only in deep-sea fishes, helps prevent cardiovascular diseases in humans. Through transgenic cloning technology, "healthy pigs" rich in "omega-3 polyunsaturated fatty acids" can also be cultivated.
Dr. Pan Dengke of the Institute of Animal Husbandry and Veterinary Medicine at the Chinese Academy of Agricultural Sciences said that “omega-3 polyunsaturated fatty acids†are found in deep-sea fish and some algae, and pigs only have “omega-6 polyunsaturated fatty acidsâ€. Scientists and technicians use a biotechnological method to convert "omega-6 polyunsaturated fatty acids" into "omega-3 polyunsaturated fatty acids" that are useful to the human body.
According to reports, the GM clone pigs obtained this time are the piglets born to the first pregnant sows, and there will be a large number of transgenic pigs to be born in the near future. Previously, 10 pigs with the "omega-3" fatty acid desaturase gene had been obtained by microinjection on experimental pig farms of the Institute of Animal Husbandry and Veterinary Research, Hubei Academy of Agricultural Sciences. The success of the “ω-3†cloned pigs was an important advancement in the preparation of transgenic cloned pigs in China, laying an important foundation for the breeding of new transgenic pigs.
