| dc.description | Minerals are essential nutrients that represent 5% of the live weight of the bovine. Although they are required in minimal amounts, their deficiencies and imbalances affect animal production, reproduction and health. To analyze the importance of minerals in bovine dairy production; the present work was based on the review of bibliographic sources. In this sense, minerals have greater potential and lower cost to increase productive and reproductive yields in dairy farms. However, it was shown that the mineral deficiency disorders with the greatest economic impact are hypocalcemia and hypomagnesemic tetany with p <0.05 for both; anemia due to iron deficiency, hypocuprosis or selenium deficiency is one of the most serious productive consequences due to low yields. The reproductive importance of these diseases lies in the fact that they can cause reproductive failure (anestrus, acyclic animals, abortions, etc.). Mineral requirements can range from Ca 0.40 to 0.80%; P 0.20 to 0.40%; Mg 0.25 to 0.30%; Cu 10 to 15 mg/kg in transition stage from dry cow to suckling; while for Fe up to 100 mg/kg DM and Se up to 0.3 mg/kg DM in different physiological periods. The results obtained are expected to be useful to professionals and producers. | es_ES |

| dc.description.abstract | Los minerales son nutrientes esenciales que representan el 5% del peso vivo del bovino. Aunque se requieren en cuantías mínimas, sus deficiencias y desequilibrios afectan la producción, reproducción y salud animal. Para analizar la importancia de los minerales en la producción bovina lechera; el presente trabajo se basó en la revisión de fuentes bibliográficas. En este sentido, los minerales tienen mayor potencial y menor costo para incrementar los rendimientos productivos y reproductivos en ganaderías lecheras. Empero, se demostró que las alteraciones por deficiencia mineral de mayor impacto económico son la hipocalcemia y tetania hipomagnesémica con p<0,05 para ambas; la anemia por ferropenia, hipocuprosis o deficiencia de selenio, es una de las consecuencias productivas más graves debido a bajos rendimientos. La importancia reproductiva de estas enfermedades radica, en que pueden provocar fallas reproductivas (anestro, animales acíclicos, abortos, etc.). Los requerimientos de minerales pueden figurar en Ca 0,40 a 0,80 %; P 0,20 a 0,40%; Mg 0,25 a 0,30%; Cu 10 a 15 mg/kg en etapa de transición de vaca seca a lactante; mientras que para Fe hasta 100 mg/kg MS y Se hasta 0,30 mg/kg MS en distintos períodos fisiológicos. Se espera que los resultados obtenidos brinden utilidad a los profesionales y productores. | es_ES |
