Reproduction is an instinct of animals, and it is the most important instinct. The stable conduct of animal reproduction activities is what makes populations continue. Reproductive behavior, as the most basic life activity of livestock, is the guarantee of livestock production and the basis of good breeding. Deepening the molecular regulation mechanism of animal reproduction will help to better improve the efficiency of livestock production and meet the increasing demands of peoples’ lives. This reprint is a collection of some reviews and original research articles related to the molecular regulation of animal reproductive activity. Some new theories and technologies related to the reproduction of livestock or model animals are also included in the reprint.
