Sex cow technology breakthrough
In Tianfeng Animal Breeding Sex Control Breeding Base in Daqing City, scientists have finally tested the patented technology of animal sex control in China after repeated trials. Only the United States, Britain and Germany have mastered the technology in the world. The core of gender control of livestock is the use of high-tech biotechnology, as well as optical and electrical principles, to sort the bull's sperm so that researchers can know the gender of these super miniature “baby cows†when the cows are fertilized, and They are separated according to the different physical and chemical characteristics of the X and Y sperm. On the day of the interview in the laboratory of Tianfeng Bioengineering Co., Ltd., the reporter happened to meet with staff working on sperm sorting. Through a series of operations, different characteristics of X sperm and Y sperm in volume, density, charge, motility, DNA content, specific antigen, etc. are presented on the computer screen. Based on these data, researchers can select the sperm that meets the requirements. It is understood that the accuracy of this technology has reached 90% -95%. With its use, cattle-raising owners will be able to realize the desire to “produce the public and have the motherâ€, thereby greatly reducing the cost of cow breeding. Researchers told reporters that it is now necessary to import more than 300 US dollars worth of high-quality embryos with an annual milk yield of 12 tons or more, and it is still not a sexually-controlled embryo. If you import a high quality cow for more than 15 months, you need 50,000 yuan. Now that researchers only buy one such imported cow, they can provide cattle owners with a large number of high-quality embryos. Using this technology, those cattle and low-yielding dairy cows can also exert “excess heat†and use the “bovine†method of abdominal breeding to transplant high-quality embryos into these cows to produce excellent dairy cows. At present, this project has already entered the trial production stage. In the next step, researchers will also study oocyte in vitro maturation and in vitro fertilization techniques. After the success, the breeding speed of good varieties will be more than 10 times higher than now.
