Ultrassonografia do rúmen e fígado de vacas de raças leiteiras dos municípios de Lavras e Ijaci/MG

Abstract

In cattle medical clinic there is a wide space for the use of ultrasound, in suboptimal use only for reproduction. Currently, due to the lower need for investment for acquiring equipment in the Brazilian market, there is unparalleled need for generating information to support the recommendations of its practical use. In this scope, the gastrointestinal organs of dairy cows can be evaluated using ultrasound, specially of the four compartments that comprise their stomach. The reticulum, rumen, omasum and abomasum can be visualized, evaluated by ultrasound for either determining characteristics within the normality standards and to subsidize the diagnostics of diseases. Some diseases such as SARA, traumatic reticuloperitonitis, demand diagnosis based on ultrasonographical findings, using information of European origin and, generally, created in production systems different from those of Brazilian conditions. Furthermore, there are no ultrasonographical parameters for Brazilian animals reared under national conditions. The objective of the present work was to review themes related to the use of ultrasound in the gastrointestinal tract of dairy cows and support its practice in cattle medical clinics.
