Xinhua net Shijiazhuang on June 21 report (reporter Yang Shouyong) the reporter learns from Heibei agriculture college, our country first in January age young kid exceeds two grandmas goat 5 tube with a strange place suckle a goat, respectively on June 14, 15 days save grass of experiment of research center of technology of project of embryo of flocks and herds to be born successfully in Heibei. The platform of technology of the embryo outside using young kid to exceed a technical plant to change manufacturing system that this indicates the province already built a Heibei to have own intellectual property, in animal embryo biology technology studies the respect fetchs significant gain.

At present these 5 kid grow growth is good. This one achievement is by Heibei farming use research center of technology of division courtyard and project of embryo of Heibei province flocks and herds greatly the task group that Sang Runzi, Tian Shujun, Professor Li Xianglong leads is finished.

In recent years, the task constituent that the person such as Professor Sang Runzi comprises was not assumed " the sheep is efficient exceed platoon and seminal fluid to save technical research and promotion " and " research of technology of grandma goat breed and set an example " two tasks research.
