This study evaluated the effects of serum (egpS) and follicular fluid (egpFF) from estrus guinea pigs as in vitro maturation (IVM) supplements for natural cycle pig oocytes. Two experiments were conducted: first assessed three IVM media, a commercial medium (CMOM) two homemade media (HMOM-P HMOM-S), oocyte using 615 bovine oocytes, while second incorporation 5%, 10%, 20% egpFF or egpS into 1744 Initially, we optimized base oocytes to determine most suitable culture conditions. The results...
El objetivo fue caracterizar el patrón de comportamiento la dinámica folicular en vaquillas Criollas (CR) al pastoreo sierra alta del Ecuador. Se realizó granja experimental Irquis Universidad Cuenca, año 2016. peso promedio 243,3±45,0 kg. Condición corporal (CC) 2,5±0,4, escala 1-5 puntos. Edad 19,9±4,8 meses. realizaron ecografías diarias durante un ciclo estral. Cada 48h se determinó los niveles Progesterona (P4). estableció dos y tres ondas foliculares (44,4 55,6%, respectivamente)....
El experimento tuvo dos fases, la primera determinó relación entre el recuento de folículos antrales (RFA) y concentración hormona anti-mülleriana (AMH) valorada día reinicio onda folicular en 61 vaquillas Holstein mestizas, criadas ganaderías del trópico alto Ecuador. La segunda fase comparó RFA valorado aspiración ecoguiada (OPU); así como, cantidad calidad los complejos cumulus ovocito (COCs) recuperados animales con alta (n=8) baja AMH. sincronización se realizó benzoato estradiol más un...
Bovine brucellosis is a worldwide zoonotic disease capable of infecting cattle for long periods time. Some animals are asymptomatic, thus maintaining the in herd. Cattle become infected after ingestion contaminated milk, feed, water; also by contact with animals, uterine secretions or aborted fetuses and vertical transmission. Little known about epidemiological situation dairy herds province Azuay. An initial step formulation control eradication programs would be implementation surveillance...
The objective of this research was to investigate the diagnostic accuracy post-mortem ultrasound in antral follicle count (AFC) determination and compare it with visual AFC grazing crossbred Holstein cows, at high altitude Ecuador. Pre-mortem blood from 80 cows collected, ovarian characteristics were analysed by techniques. counts stratified as high, medium or low terciles. Mean AMH concentration pre-mortem 280.1 ± 15.53 pg/mL. obtained inspection (26.9 9.49 follicles) 23.8% higher than...
