CARACTERÍSTICAS MORFOMÉTRICAS DE OVÁRIOS DE VACAS MESTIÇAS DE DESCARTE COLETADOS EM ABATEDOURO

Abstract

The objective was to evaluate morphometric characteristics of the ovaries and incidence of corpus luteum and ovarian follicles in empty zebu crossbreed’s cows obtained from slaughterhouses, in the region of Uberlândia, Minas Gerais. The average values of length, width and thickness of the rights ovaries (OD) were, respectively, 3.5 cm, 2.3 cm and 1.70 cm. For the left ovary (OE) the measures were: 3.4 cm, 2.0 cm and 1.60 cm. The mean diameter of the follicles found in the OD was 1.1 cm and OE 0.8 cm. The comparison between findings on the right and left ovaries was performed using the T test, with significance level of 5% (p <0.05) and the width was higher in right ovaries (p-value: 0.02). Of all the corpus luteum, 61% were present in the OD and 39% present in the OE. To classify the type of this corpus luteum, it was found that 68% of corpus luteum were protruding and 32% were included. The size of the ovaries and the high incidence of included corpus luteum should be considered as major factors when performing gynecological examination by rectal palpation.
