Abstract: Zinc is an essential micromineral for physiological processes such as the growth, development, and breeding in animals, and it ranks only second to iron micromineral according to micronutrient requirements.Zinc is widely distributed with tissue differences and is mainly absorbed in jejunum and ileum of animal.Both zinc-regulated transporter-like proteins (Zip) and zinc transporter (ZnT) of Zinc transport proteins, and metallothionein involve in zinc balance and metabolism in animal.Zinc is the component and the activity factor of many enzymes in animal, it on the one hand regulates cell processes as the constituent of enzyme, and on the other hand involves signal transduction as the signal molecule to regulate animal physiological functions of feed intake, redox, immune, metabolism, reproduction.At present, dietary zinc mainly includes inorganic, organic, and nano-zinc styles, which display different biological value.Dietary zinc is associated with physiological functions on feed intake, redox, immune, metabolism, reproduction of pigs, while zinc requirement varies with swine nutrient requirements during different growth stages.In addition, physiological regulation and applicative effects of dietary zinc display variations due to zinc levels and sources.The purpose of this article is to provide theoretical references for the deep excavation of microelement zinc, thereby promoting the healthy development of pig industry.
