MICHELOUD, Juan F. SUAREZ, Victor H. MARTINEZ, Gabriela M. ROSA, Diana E. VENTURA, María Belén MATTIOLI, Guillermo A. mineral deficiency beef cattle northwestern Argentina Deficiencia mineral bovinos de carne noroeste argentino Mineral deficiencies are a problem of great productive impact worldwide. In the Argentine Northwest (NOA) extensive breeding is one of the most important economic activities and it is in frank growth. In the NOA, studies on deficiency diseases are scarce and partial. The present work aims to describe seasonal variations of serum levels of calcium, phosphorus, magnesium, copper and zinc in beef cows and rearing calves. In a farm, 20 cows and 20 weaned heifer calves were selected, which were maintained under grazing conditions and without external supplementation. Blood samples were taken at intervals of 3 months for one year. Serum levels of calcium, magnesium, copper and zinc were determined by atomic absorption spectrophotometry and phosphorus by UV-visible spectrophotometry. The results indicate the existence of moderated hypocupremia in the calves (48.6 ± 11μg / dl) during all sampled periods. Cows presented normal values (66 ± 3.5 μg / dl) but close to the lower limit during some sampling. Subnormal levels of phosphorus were observed during the summer (December and March) in both categories. This work confirms that copper and phosphorus can behave as limiting factors in the evaluated conditions. Las deficiencias minerales son un problema de gran impacto productivo a nivel mundial. En el Noroeste argentino (NOA) la cría extensiva es una de las actividades económicas más importantes y está en franco crecimiento. En el NOA, los estudios sobre enfermedades carenciales son escasos y parciales. El presente trabajo tiene por objeto describir variaciones estacionales de los niveles séricos de calcio, fósforo, magnesio, cobre y zinc en vacas de cría y terneras de recría. En un establecimiento ganadero se seleccionaron 20 vacas y 20 terneras que fueron mantenidos en condiciones de pastoreo y sin suplementación externa. Se efectuaron muestreos de sangre a intervalos de 3 meses durante un año. Se determinaron niveles séricos de calcio, magnesio, cobre y zinc por espectrofotometría de absorción atómica y de fósforo por espectrofotometría uv-visible. Los resultados indican la existencia de hipocupremia moderada a leve en las terneras (48,6±11μg/dL) durante todos los períodos muestreados. Las vacas presentaron valores promedio normales (66±3,5 μg/dL) pero cercanos al límite inferior durante algunos muestreos. Se observaron niveles subnormales de fósforo durante el verano (diciembre y marzo) en ambas categorías. Este trabajo sugiere que el cobre y el fósforo pueden comportarse como factores limitantes en las condiciones evaluadas.
