Today, nanotechnology has made great strides, important in biotechnology and biomedicine related to human and animal sciences, including increasing health safety, productivity, and rising national revenue. There are various categories of nanomaterial applications in veterinary medicine such as effective diagnostic and therapeutic tools, drug delivery, animal nutrition, reproduction and reproduction, and essential additives. Additional benefits include detection of bacteria, proteins, biological molecules, antimicrobial agents, dietary supplements, nutrient delivery, and reproductive resources. There are many nanomaterials and nanocomposites that can be used in nano medicine such as metal nanoparticles, liposomes, carbon nanotubes, and quantum dots. In the near future, nanotechnology research will have the potential to develop new tools to improve animal health and production. Therefore, this paper is designed to highlight the novel techniques created by nanotechnology for use in improving animal health and production.
