dc.description.none.fl_txt_mv This study assessed the morphometric and functional characteristics of oocytes from 10 native cows to the Ecuadorian Andes, collected by transvaginal follicular aspiration (OPU) and oocytes collected post mortem (PM) from abattoir ovaries. For this purpose, 1157 cumulus-oocyte complexes (CCOs) of the OPU group (n=271) and PM group (n=886) were recovered in 10 repetitions per group by follicular aspiration at 90 mm Hg pressure and classified as A, B or C, according to the characteristics of the cytoplasm and cumulus cells. The activity of the enzyme glucose 6 phosphate dehydrogenase (G6PD) was determined as an indicator of follicular growth and maturation and the integrity of the plasma membrane by staining the CCOs with cresyl brilliant blue (BCB +) and trypan blue, respectively. The size (diameter and volume) of the oocytes was evaluated using CaptaVisio® software v. 5.1. The data were analysed by logistic regression and by the SAS general linear model, and the means were compared by the least square method. The results showed that the oocytes of the PM group had a larger diameter (126.0 ± 0.48 vs. 122.7 ± 0.79 µm; p<0.01) and integrity of the plasma membrane (86.0 vs. 76.8%; p<0.05) than the OPU group. However, quality A and B oocytes did not show significant differences between groups with respect to plasma membrane integrity and BCB + values. The results suggest that, although the fact that the size and viability were more affected in the oocytes aspirated by OPU, those of quality A and B from both sources showed similar values regarding the integrity of the plasma membrane and metabolic condition to continue. maturation.
El estudio analizó las características morfométricas y funcionales de ovocitos de 10 vacas nativas de los Andes ecuatorianos, colectados por aspiración folicular transvaginal (OPU) y de ovocitos colectados post mortem (PM) de ovarios de matadero. Para este propósito, 1157 complejos cúmulo-ovocito (CCOs) del grupo OPU (n=271) y PM (n=886) fueron recuperados en 10 repeticiones por grupo por aspiración folicular a 90 mm Hg de presión y clasificados en calidad A, B o C, de acuerdo con las características del citoplasma y células del cúmulo. Se determinó la actividad de la enzima glucosa 6 fosfato deshidrogenasa (G6PD) como indicador de crecimiento folicular y maduración finalizado y la integridad de la membrana plasmática tiñendo los CCOs con azul brillante de cresilo (BCB+) y azul de tripán, respectivamente. Se evaluó el tamaño (diámetro y volumen) de los ovocitos usando un software CaptaVisionÒ (v. 5.1). Los datos se analizaron por regresión logística y por el modelo lineal general del SAS, y las medias se compararon por el método de los mínimos cuadrados. Los resultados mostraron que los ovocitos del grupo PM presentaron mayor diámetro (126.0±0.48 vs 122.7±0.79 µm; p<0.01) e integridad de la membrana plasmática (86.0 vs 76.8%; p<0.05) que el grupo OPU. Sin embargo, los ovocitos de calidad A y B no registraron diferencias significativas entre grupos con respecto a la integridad de la membrana plasmática y valores de BCB+. Los resultados sugieren que, a pesar de que el tamaño y la viabilidad fue más afectada en los ovocitos aspirados por OPU, los de calidad A y B provenientes de ambas fuentes mostraron valores similares con respecto a la integridad de la membrana plasmática y condición metabólica para proseguir la maduración.
