DE SOUSA FERREIRA, Joyanne Mirelle et al. Vitamins and minerals in the cattle nutrition. rev. colombiana cienc. anim. Recia [online]. 2023, vol.15, n.2, e02.  Epub Feb 21, 2024. ISSN 2027-4297.  https://doi.org/10.24188/recia.v15.n2.2023.969.

Animal feed is the factor that most burdens a production system. Thus, the use of different animal feeding strategies is still the great challenge of animal nutrition, taking into account the nutritional requirements of different categories of ruminants, especially cattle in tropical regions, given that seasonality in forage production directly affects cattle production, promoting inadequacy in meeting the nutritional requirements of animals, mainly in minerals and vitamins. A diet that does not meet the nutritional requirements of ruminants generates losses in the production system, in addition to, in more serious cases, causing the loss of the animal. Studies that address the effect and importance of vitamins and minerals in bovine nutrition are scarce and necessary. Recently the National Research Council (NRC) presented new records of the nutritional requirements of vitamins and minerals. These changes provide a significant economic impact on animal nutrition. In this sense, the objective of this review was to bring information about vitamins and minerals in the nutrition of grazing cattle.
