China's first "test milk goat" was born in Hebei and Fuwa had the same name

In China, the first case of super-rowing of two young goats at the age of one month was born with five “test-milk goats”, which were successfully brought to the experimental ranch of Hebei Niuyang Embryo Engineering Technology Research Center recently. Because these five “test-tube milk goats” were born at the time of the opening of the Beijing Olympic Games, they were given the names 蓓蓓, Jing Jing, Huan Huan, Ying Ying and Nini.

This achievement was completed by the research group led by Hebei Agricultural University and the Animal and Embryonic Engineering Research Center of Hebei Niuyang, led by Professors San Runzi, Tian Shujun, and Li Xianglong. It is understood that during the “Eleventh Five-Year Plan” period, the research group undertook two research projects, “Study and Promotion of Sheep Efficient Superovulation and Semen Storage Technology” and “Study and Demonstration of Dairy Goat Breeding Technology”. Following the successful acquisition of the first “test-tube sheep” for the first superabdominal lamb (hybrid cross) young lambs in China in September last year, another study was conducted on the superovulation of dairy lambs. The research group used a high-tech biotechnology system that integrates techniques such as superovulation, live egg collection, in vitro maturation, in vitro fertilization, in vitro embryo culture, and embryo transfer to one-month-old dairy goats. Scorpion gestation, and on the 14th and 15th of June, were born 2 and 3 "test milk goats." At present, the five lambs are well developed.

Experts believe that this technology enables lambs to ovulate at 1 month of age and become mothers at 6 months of age. This technology can not only fully exploit and utilize the early reproductive potential of elite breeding stocks, shorten the gap between generations, and speed up the breeding process, but also can be used for animal cloning, genetic transformation and other embryonic engineering research. Provides the desired source of oocytes and embryos to promote the development of embryonic engineering. At the same time, it also provides a new technical way to expand milk sources and solve the shortage of milk sources.

Hydraulic Cylinder

The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or oscillating motion). It has a simple structure and works reliably. When it is used to realize reciprocating motion, the deceleration device can be dispensed with, and there is no transmission clearance, and the movement is stable, so it is widely used in the hydraulic system of various machinery. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between its two sides, and the hydraulic cylinder is basically composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.
