China's first batch of space black chickens have hatched recently

Introduction: China's first batch of space black chickens have been hatched on April 23 this year There are three chicks hatched this time, two of them are cocks and one is a hen Professor Yang Ning, director of the poultry science teaching and Research Office of the school of animal science and technology of China Agricultural University, who has undertaken this research project, is really excited He said that the chickens we hatched include both cocks and hens, which shows that we can continue to obtain the offspring of space black chickens and realize the goal of space breeding Professor Yang Ning said that in the black egg space incubator of Shenzhou-3 unmanned spacecraft launched on April 4, we put nine black bone chicken eggs in total, and now three chickens can hatch This result is more fortunate than that of Japan, which carried the U.S space shuttle in 1992, put 10 eggs and hatched only one chicken When talking about why we choose black bone chicken for space breeding experiment, Professor Yang Ning said: "we choose black bone chicken mainly considering its purity, skin, body shape and incubation speed Black bone chicken is light, small and slow-moving It has remarkable and unique appearance and production performance, so it is easy to be different from other breeds At the same time, black bone chicken is more nutritious, black bone chicken has higher medicinal value and stronger ornamental Considering these three advantages, we choose black bone chicken for the first space animal breeding experiment " Professor Yang Ning introduced that animal genetic breeding is one of the main means to change the breeding ability and efficiency of poultry Through mature genetic breeding technology, the yield, feed utilization rate and nutrient composition of poultry can be improved "We believe that with our observation of the growth, development and reproductive performance of the offspring of these space black bone chickens, we will explore the impact of the space environment on the chicken embryo, so as to accumulate experience for the development of animal space breeding in China," Yang said at the end
