Abstract:The symbiotic relationship between rumen microbes and ruminants is an important knowledge that must be mastered by undergraduate students in animal sciences. The authors employ a problem-oriented teaching method to enable students to better grasp the role of rumen microorganisms in the growth and development of ruminants, and to achieve active cultivation in the quality and ability of the students to rationally feed ruminants, correctly prevent ruminal diseases, and carry out research related to ruminants in the future.
