Abstract: The main problem in teaching of Animal Genetic Resources is the prominent contradiction between ＂wide content＂ and ＂less learning time＂. The key method to solve this problem is the application of Internet technology. Using the Internet technology and resources, we explored the teaching contents, teaching methods and examination methods. The expansion of Internet content based on teaching materials was carried out. In the teaching method of ＂student speaking plus teacher evaluation＂, we explored the teaching reform based on curriculum papers and expanded teaching depth. Guided by the thinking of the Internet, we used QQ and WeChat to establish communication group, and flexible and instant teaching links were extended during the course. Remarkable achievements were made after the exploration of a series of reforms in teaching of postgraduate Animal Genetic Resources.
