Construction of Value Evaluation System for Beef Genetic Resources Breeding Varieties——Taking Datong Yak as an Example
Livestock and poultry genetic resources are an important part of biodiversity,and improved varieties are the material basis for the healthy and sustainable development of beef cattle industry. Breeding is an effective way to realize the protection and sus-tainable utilization of beef cattle genetic resources,and it is very important to establish a value evaluation system of beef cattle ge-netic resources. Based on the FAO livestock and poultry genetic resources value framework,this paper summarized,analyzed and evaluated the relevant literature,research results and theoretical viewpoints at home and abroad. Combined with the reality of Chi-na,the evaluation system of genetic resources value of beef breeding varieties was preliminarily established. Taking Datong yak as an example,the value of its genetic resources was divided into direct use value,indirect use value,potential use value and protection value. The evaluation methods were determined as three main methods:market price method,opportunity cost method and shadow engineering method. This paper proposes to establish the value evaluation system of beef cattle genetic resources as soon as possible,further improve the value evaluation method of beef cattle genetic resources,and promote the establishment of the property right system of livestock and poultry genetic resources,so as to provide decision support for promoting the high-quality development of animal husbandry and biodiversity protection in China.
