Valuing Indigenous Pig Breeds in China: Empirical Analysis Based on Their Utilization Status and Sustainable Development

China is one of the countries with the richest Animal genetic resources (AnGR) in the world, and also the largest producer and consumer of pigs.The pig industry is huge, but more than 90% of pork consumption relies on imports, while local pig breeds are neglected, and many of them are even on the verge of extinction.In order to study the utilization status of local pig breeds and promote the protection、development, and utilization, this study conducted an in-depth analysis of the utilization status of local pigs by combing the utilization status and cost-benefit analysis.The results showed that the overall population of Min pig has increased and has been extensively used in production. However, due to the high input cost and low output income, the income is negative and production efficiency is low. Therefore, the pigs have not been fully and effectively utilized by the people.The study further observed that in the general commercialization environment over the years, a range of incentives and protection measures have achieved a balance. This has resulted in a certain level of balance between policy implementation and commercial development, leading to an increase in the number of pigs and improving the situation of endangered varieties. The findings of this study provide a theoretical foundation for the preservation, development, and sustainable utilization of local pig genetic resources.
