Creating Modern Technological System For Grass Product Processing To Guarantee Macroscopic Food Security, Tianwei Wang, Jin Zhong
Creating Modern Technological System For Grass Product Processing To Guarantee Macroscopic Food Security, Tianwei Wang, Jin Zhong
Bulletin of Chinese Academy of Sciences (Chinese Version)
The construction of a scientific and technological system of ecological grass-based livestock husbandry (GLiH) provides technical support for the "Macroscopic Food Security" concept and the "National Strategy of Giving Priority to Ecology and Green Development" in the new era. At the same time, it represents an urgent need for the domestic circulation. Scientific grass processing and production of forage grass can help form the GLiH industrial chain by connecting the front-end "forage grass cultivating" and back-end "livestock raising". However, China still faces many problems in terms of forage grass processing and production, and the development of the grass industry. On …

Bulletin of Chinese Academy of Sciences (Chinese Version)
China enters into a new era with high demand for nutritional and healthy food, and hence needs to adjust the agricultural production system to balance cereal production and livestock farming. Between the years 2010-2019 the production of red meat and milk has fallen far behind the consumption demand, resulting in sourcing and import of large quantity of red meat and milk products from the international market. In comparison to the average consumption levels in Asia and global, China's consumption will continue to grow in the future, presenting a great challenge to the goals of 85% self-sufficiency rate for beef and …

Bulletin of Chinese Academy of Sciences (Chinese Version)
The area of grassland in China is about 392.8 million hm2, covering 40.9% of land surface of China. Grasslands not only serve as important green barriers for national ecological security but also as basic means of production for local farmers and herders. However, the grasslands in China have been unevenly deteriorating since 1980s in large areas. To date, the overall condition of grasslands in China remains worsening, with some area getting better. Such a situation severely constrains the developments of ecological civilization and social economy in China. Here, we analyze the current state and issues in grassland restoration and conservation …

Current Situation And Prospect Of Forage Breeding In China, Jingbo Jin, Tai Wang, Youfa Cheng, Lei Wang, Jingyu Zhang, Haichun Jing, Kang Chong
Bulletin of Chinese Academy of Sciences (Chinese Version)
High-yield and high-quality forage varieties are the key to sustainable development of grass-based livestock husbandry in China. However, the forage breeding was started late in China, and the progress is very slow, and the forage varieties of independent intellectual property rights are seriously lacked. Forages generally have self-incompatibility, natural allogamy, polysomic inheritance, and marked inbreeding effects. Subsequently, it is difficult to characterize agronomically important complex traits, resulting that the breeding technology is still in the 2.0 era of hybrid breeding. The molecular design-based breeding is a fine strategy to speed up the breeding process, however, there is a lack of …
