Resumen
El objetivo del trabajo fue evaluar la incidencia de glutation peroxidasa en la peformanceproductiva y salud uterina de vacas lecheras suplementadas con selenio. Durante los mesesde octubre del año 2015 y marzo del año 2016 se muestrearon un total de 68 vacasHoltein multíparas. Se dividieron al azar en dos grupos de 34 animales y a uno de ellos sele administró vía oral en el último tercio de preñez un bolo de liberación lenta de Selenio(GS), el otro grupo no recibió suplementación (GT). Se extrajo sangre para ladeterminación de la concentración de la enzima seleno-dependiente glutatión peroxidasa(GHS-Px) al momento de la puesta del bolo y posteriormente el periodo pospartocomprendido entre los 21 y 56 días. Se evaluó la performance productiva y la saluduterina de las vacas. Se concluyó que la administración extra de selenio favorece laperformance productiva y la salud uterina de las vacas lecheras ya que se incrementa laGHS-Px en las vacas más productoras y aquellas que tuvieron menos patologías uterinasque las que no incrementaron dicha concentración.
The objective of the work was to evaluate the incidence of glutation peroxidase in the productive performance and health uterine of dairy cows supplemented with selenium. During the months of october of the year 2015 and march of the year 2016, a total of 68 Holteins cows were sampled. They were randomly divided into two groups of 34 animals and one of them was given a slow-release Selenium bolus (GS) in the last pregnated tercium period, the other group did not receive supplementation (GT). Blood was drawn for the determination of the concentration of the selenodependent enzyme glutation peroxidase (GHS-Px) at the time of bolus application and subsequently the postpartum period between 21 and 56 days. The health uterine and productive performance of the cows was evaluated. It was concluded that the extra administration of selenium favors the productive perfomence and health uterine of the dairy cows since the GHS-Px is increased in the more productive cows and those that had less uterine pathologies than those that did not increase
