Se realiza un estudio sobre la prevalencia de las malformaciones uterinas recogidas en 1489 hembras bovinas sacrificadas en mataderos de León (España). Se diagnosticaron 9 casos (0.6%) de malformaciones: 5 de hipoplasia (55.6% de las mismas), 1 de aplasia total (11. 1%), 2 de aplasia segmentaria de los conductos de Müller (22.2%) (uno de los casos clasificado de útero unicorne) y 1 de útero didelfo. Dentro de los grupos de edad, las malformaciones fueron halladas principalmente entre los 2 y 4 años (3%) y dentro de las razas, la más afectada fue la Pardo Alpina (1.1%). La infertilidad, en mayor o menor grado, provocada por las malformaciones y su carácter hereditario aconsejan la eliminación de los animales afectados.
A statistic and morphological study on congenital anomalies of the uterus diagnosed during the examination of 1,489 bovine females sacrificed in slaughterhouses in León (Spain) was carried out. Nine cases of congenital anomalies (0.6% of the population), which were as follows: 5 cases of hypoplasia (55.6% of all anomalies), 2 cases of segmental aplasia of the müllerian ducts (22.2%) (one of them was classified as uterus unicomis), 1 case of complete agenesia (11.1%) and 1 case of uterus didelphys were diagnosed. With regard to age groups, anomalies were more frequent in the 2-4 yearold group (3%) and with regard to breeds, the Swiss Brown was the most affected (1.1%). Animals affected by these lesions should be sacrificed because of their infertility and hereditary nature.
