Core Viewpoint - The successful cloning of three healthy white wash piglets using somatic cell nuclear transfer technology marks a significant advancement in the preservation and development of endangered local pig breeds in Guizhou Province [1][2]. Group 1: Cloning Achievement - Guizhou University successfully cloned three healthy white wash piglets, including two females and one male, using somatic cell nuclear transfer technology [1]. - The cloning process involved the collection of fibroblast cells from the ear tissues of a male and female white wash pig, which were preserved in liquid nitrogen at -196°C for over two years [1]. - A total of 315 cloned embryos were created, with three piglets being born on September 20, weighing 1.54 kg, 1.37 kg, and 1.36 kg, all of which are developing well [1]. Group 2: Importance of Local Pig Breeds - Local pig breeds are crucial for biodiversity and are considered strategic resources for achieving self-sufficiency in breeding [2]. - Guizhou Province is home to 11 types of local pig genetic resources, including the white wash pig, which is facing threats from the rapid development of modern pig farming and the encroachment of foreign breeds [2]. - Traditional live preservation methods face challenges such as high costs, disease risks, and genetic drift due to long-term isolation [2]. Group 3: Technological and Cultural Impact - The successful application of this technology establishes a comprehensive protection system for local pig breeds, combining live preservation, somatic cell cryopreservation, and crisis recovery [2]. - The local breakthrough in this technology is expected to accelerate the rescue and restoration of endangered local pig breeds, enhancing their economic value and supporting the preservation of agricultural cultural heritage [3].
