Glutathione peroxidase activity in dairy cows with and without selenium supplementation

The aim of this work was to evaluate glutathione peroxidase (GPX) activity levels in dairy cows supplemented and not supplemented with intra-ruminal selenium (Se) boluses. The GPX activity of 96 clinically healthy primiparous and multiparous Holstein dairy cows, from a commercial establishment in Ce...

Masso, R. J. Rinaudo, A. Marini, P. R. Dairy cows ante-partum selenium intra-ruminal bolus Vacas lecheras preparto selenio bolo intra-ruminal The aim of this work was to evaluate glutathione peroxidase (GPX) activity levels in dairy cows supplemented and not supplemented with intra-ruminal selenium (Se) boluses. The GPX activity of 96 clinically healthy primiparous and multiparous Holstein dairy cows, from a commercial establishment in Centeno´s town, Santa Fe Province (Argentina), was assessed. According to the individual GPX determinations, two categories of cows were defined taking 130 U/gHb as the cut value. The cows in each category were randomly divided in two subgroups, one of which received an intra-ruminal bolus of long-acting Se (Permatrace®) while the other remained unsupplemented. Next, two new enzymatic activity determinations were made: ante-partum (between 30 and 15 days before calving) and post-partum (between 30 and 45 after calving). The 35.4% of the cows presented enzyme activity values lower than the cut value. Cows with low basal values of GPX activity not supplemented with Se boluses did not significantly modify the basal values. In cows with low basal values of GPX activity and supplemented with Se, a significant increase in enzymatic activity was observed. It is concluded that a significant proportion of cows have low GPX activity, enzymatic activity levels are modified according to the moment of evaluation in relation to calving and that supplementation with intra-ruminal Se is an effective strategy to increase the enzyme activity. El objetivo del presente trabajo fue evaluar los niveles de la actividad glutatión-peroxidasa(GPX) en vacas lecheras suplementadas y sin suplementar con selenio (Se) intra-ruminal.Se determinó la actividad GPX de 96 vacas Holstein primíparas y multíparas, clínicamentesanas, procedentes de un establecimiento comercial de la localidad de Centeno, Provincia deSanta Fe (Argentina). Se definieron dos categorías de reses según las determinaciones individuales de GPX tomando como valor de corte 130 U/gHb. Los animales de cada categoría se dividieron aleatoriamente en dos subgrupos, uno de los cuales recibió un bolo intraruminalde Se de larga acción (Permatrace®) mientras que el otro permaneció sin suplementar. Acontinuación, se efectuaron dos nuevas determinaciones de la actividad enzimática: preparto(entre los 30 y los 15 días previos al parto) y posparto (entre los 30 y los 45 posteriores alparto). El 35,4% de las vacas presentó valores de actividad de la enzima menores al valor decorte. Los animales con bajos valores basales de actividad GPX no suplementadas con bolosde Se, no modificaron significativamente los datos basales. En las vacas con bajos valoresbasales de actividad GPX y suplementadas con Se, se observó un aumento significativo de laactividad enzimática. Se concluye que una proporción importante de animales presenta bajaactividad GPX, que los niveles de las enzimas se modifican según el momento de la evaluaciónen relación al tiempo del parto, y que la suplementación con bolos de Se intra-ruminalconstituye una estrategia efectiva para aumentar la actividad de la enzima.
