Abstract
The aim of this study was to determine the kinetics and sperm morphometry in sexed and conventional frozen semen of Brown Swiss bulls using the Integrated Sperm Analisys system. Ten straws of sexed semen and 10 straws of conventional semen imported from USA were used. The values of kinetics (curvilinear velocity [VCL], average velocity [VAP], rectilinear velocity [VSL], amplitude of lateral head displacement [ALH], beat frequency [BCF], linearity index [LIN [, index of straightness [STR], oscillation index [WOB]) and sperm morphometry (area, length, width and perimeter of the head of the sperm) were similar between sexed and conventional semen of Brown Swiss bulls frozen in straws. El estudio tuvo como objetivo determinar la cinética y morfometría espermática de semen congelado sexado y convencional de toros Brown Swiss utilizando el sistema Integrated Sperm Analisys. Se utilizaron 10 pajillas de semen sexado y 10 pajillas de semen convencional de origen americano. Los valores de la cinética (velocidad curvilínea [VCL], velocidad media [VAP], velocidad rectilínea [VSL], amplitud del desplazamiento lateral de cabeza [ALH], frecuencia de batido [BCF], índice de linealidad [LIN[, índice de rectitud [STR], índice de oscilación [WOB]) y morfometría espermática (área, largo, ancho y perímetro de la cabeza de los espermatozoides) fueron similares entre el semen sexado y convencional de toros Brown Swiss.
