Plasma zinc concentrations in beef cows at Salado River Basin
Zinc (Zn) is an essential micromineral and its deficiency can affect the productive and reproductive efficiency in cattle. A multicenter observational study was carried out to evaluate Zn status in breeding cows at Salado River Basin (Buenos Aires, Argentina). The study included 110 cow-calf operations, in which blood samples (n = 1078 cows) were collected and analyzed by using atomic absorption spectrophotometry. Cows were classified according to their plasma Zn concentration values as physiologically adequate (≥ 90 μg/dl), marginal (between 80 to 89 μg/dl) and deficient (<80 μg/dl). A descriptive statistical analysis was performed using the SAS program MEANS procedure. The average plasma Zn concentration was 102.8 ± 16.4 μg/dl and 31.4 % of the cows in each herd showed marginal or deficient values. The highest percentage of marginal or deficient cows was recorded in winter (47.7 %), while the lowest percentage was recorded in autumn (21.3 %). These results show that there is Zn deficiency in cow-calf operations of Salado River Basin.

El zinc (Zn) es un micromineral esencial y su carencia puede afectar la eficiencia productiva y reproductiva del ganado. Con el objetivo de evaluar el estatus de Zn en vacas de cría de la cuenca deprimida del río Salado (centro este de la provincia de Buenos Aires, Argentina), se realizó un estudio observacional multicén-trico en 110 rebaños en el que se recolectaron muestras de sangre (n = 1.078 vacas) y se analizaron mediante espectrofotometría de absorción atómica. Las vacas se clasificaron según la concentración plasmática de Zn en fisiológicamente adecuadas ≥ 90 μg/dl, marginales entre 80 y 89 μg/dl y carentes <80 μg/dl. Se realizó un análisis estadístico descriptivo mediante el procedimiento MEANS del programa SAS. La media de la concentración plasmática de Zn fue de 102,8 ± 16,4 μg/dl y el 31,4 % de las vacas de cada rebaño presentó valores marginales o de carencia. Durante el invierno se registró el porcentaje más alto de vacas con concentraciones plasmáticas de Zn marginales o carentes (47,7 %), mientras que en otoño se registró el porcentaje más bajo (21,3 %). Los resultados obtenidos demuestran que existen valores plasmáticos marginales y de carencia de Zn en vacas de cría de la cuenca deprimida del río Salado.
