Role of Nanoparticles in Veterinary Medicine and as Feed Additive in Livestock

Nanotechnology is gaining more popularity in various applied fields due to its versatile applications. Different world challenges, including pollution, resistance against antibiotics, disorders in human/ animal digestive systems, contaminants of feeds, health management & feed efficiency, etc., can be overcome by using nanoparticles. Nanoparticles can be used as antibiotics, as feed additives, and can also be used against mycotoxin and as biocidal agents. The efficiency and productivity of various items could be improved using multiple supplements like enzymes, yeast, plant extracts, etc. Many efforts are going on to improve productivity and efficiency using different supplements, such as yeast, enzymes, probiotics, and plant extracts. Nanomaterials can effectively replace all. In this chapter, we will discuss various types of metal/metal oxide nanoparticles and their role in livestock as feed additives, pointing out their level of toxicity as well. The current and future regarding the permissible nanomaterials to be used in veterinary-related products will also be highlighted.
