Study on Dynamic Information of Animal Genetic Resources in China

The dynamic information of 331 animal genetic resources in 17 important animal genetic resource provinces (regions) was analyzed. According to the population inbreeding coefficient, combining with the information of population dynamic change trend and cross degree, these genetic resources for threatened degrees were classified. The results indicated that the population size of 138 breeds had increased, 147 breeds had decreased, 3 breeds were constant, 7 breeds (or varieties) were extinct, 9 breeds (or varieties) were critically endangered and needed urgently conserve, 50 breeds (or varieties) were endangered and should be conserved. We put forward a conservation and utilization plan for animal genetic resources.

Evaluation of Animal and Plant Resources Status Quo after the Reservoir Construction in Turks River and Protection Measures

[Objective] The aim was to assess the status quo of animal and plant resources in Turks River after the construction of the reservoir.[Method] Through field investigation,document check and sample identification,the distribution of animal and plants resources in Turks River after the construction of the reservoir was studied and corresponding protection measures were proposed.[Result] Under the influence of reservoir,there were fifteen types of rare animals,one species of national primary protected animals,seven species of national secondary protected animals,one species of provincial primary protected animals,six species of provincial secondary protected animals;there were twenty one species of rare plants,including two species of national secondary plant,five species of national tertiary protected animals,six types of Xinjiang primary protected plants,two species of Xinjiang secondary protected plants and six types of tertiary protected plants in Xinjiang.Protective policies for the land ecological environment were proposed,including corresponding compensation according to the rules and policies of government,plans being formulated for rare species protection,construction of natural reserves and artificial breeding base,usage of the environment in the reservoir and changes of ecological situation etc.[Conclusion] The study provided basis for the protection of animal and plants resources in Turks.

Review on the development of genotyping methods for assessing farm animal diversity

Advances in molecular biotechnology have introduced new generations of molecular markers for use in the genetic improvement of farm animals. Consequently, more accurate genetic information can be obtained to better understand existing animal genetic resources. This review gives a brief summary on the development of genetic markers including both the classical genetic markers and more advanced DNA-based molecular markers. This review will help us better understand the characteristics of different genetic markers and the genetic diversity of animal genetic resources.

Study Progress on Animal Feces Treatment by Microorganism

With the fast development of livestock breeding,serious environmental pollution issues caused by the large accumulation of animal feces have arisen increasingly. It is of great importance to re-use these organic matter resources in order to ease the environmental and resource problems. And we reviews the significance of microorganism for livestock development and particularly the close relationship between microorganism and biodegradation of animal breeding residues. These bacteria play important roles in odor control,degradation and conversion of organic matters,and even the reduction of animal waste discharging amount by adjusting the feed nutrition proportion or improving the digestibility of nutrients. Consequently,it shows good application prospect of microbe practice in the improvement of contaminated environment resulting from livestock farming residues and the utilization of livestock manure resource.
