Telocytes have been identified in almost all kinds of organs and tissues in human, rat, mouse and other mammals, and they are considered to be important during tissue regeneration and repair, and they have potential roles in the pathogenesis of some diseases. However, there is still short of knowledge about telocytes in agricultural animals. In this chapter, we try to testify the existence of telocytes and demonstrate the morphological and ultrastructural characteristics of telocytes in agricultural animals. The results confirmed the existence of telocytes in the reproductive and gastrointestinal tract of agriculture animals, and they share the same morphology and ultrastructure with telocytes in other reported mammals. The results also promoted the study of telocytes and enhanced the researchers to pay more attentions on this new type of interstitial cells and it is helpful to create new treatments for the various reproductive disorders and gastrointestinal problems.
