Quistes foliculares y cuerpo lúteo quístico en bovinos de sacrificio. I. Prevalencia
1989
espanolSe ha realizado un estudio sobre la prevalencia de los quistes foliculares (luteinizados o no) y cuerpo luteo quistico (CLQ) en 1.489 hembras bovinas sacrificadas en mataderos de Leon. Se recogio un 11,8% de quistes foliculares y, dentro de estos, el 88,6% fueron no luteinizados y el 11,4% luteinizados. Dentro de los grupos de edad, los quistes foliculares se presentaron con mas frecuencia entre los 11 a 15 anos (13,4%) y, respecto a la raza, la mas afectada fue la Frisona (14%). Estos quistes se encontraron asociados estadisticamente con otras alteraciones genitales, destacando la hiperplasia endometrial quistica. Asimismo, los no luteinizados fueron mas frecuentes en el verano mientras los luteinizados lo fueron en el invierno. La prevalencia del CLQ fue 5,8%. Dentro de las razas, la mas afectada fue la Alistano-Sanabresa (7,1%) y, en cuanto a los grupos de edad, se presento con mas frecuencia de 2-4 anos. Esta alteracion se presento con una mayor frecuencia en primavera y no estaba asociada estadisticamente a otras alteraciones genitales. EnglishA study on the incidence of cystic (luteinized or not) follicles and cystic corpora lutea in 1489 bovine females sacrificed in the slaughterhouses of Leon was carried out. The frequency of cystic follicles was 11.8%, being the 88.6% of them not luteinized and the 11.4% luteinized. With regard to the age of the animals the cystic follicles were showed with a higher frequency (13.4%) in females from 11 to 15 years. With regard to the breed, the Friesian had the highest incidence (14%). These cysts were statistically associated with other genital lesions such as the cystic endometrial hyperplasia. Furthermore cystic not luteinized follicles had a higher frequency during the summer while the luteinized ones during the winter. The incidence of the cystic corpora lutea was 5.8%. Amongst the breeds the Alistano-Sanabresa was more affected (7.1%) than the others and with regard to the age the females from 2 to 4 years had the highest incidence. This lesion was observed mainly during the spring and it was not statistically associated with other genital lesions.
