EFFECT OF THE DEPOSITION SITE OF SEMINAL PLASMA ON THE OVULATION AND CORPUS LUTEUM DEVELOPMENT IN ALPACAS

Descripción del Articulo

The present study was carried out to evaluate the effect of deposition site of seminal plasma on the ovulation rate and size of corpus luteum in alpacas. Non-lactating females bearing a ≥7 mm follicle detected by ultrasound were selected (n = 91). Follicular wave was synchronized by injecting 5 mg o...

dc.description.none.fl_txt_mv The present study was carried out to evaluate the effect of deposition site of seminal plasma on the ovulation rate and size of corpus luteum in alpacas. Non-lactating females bearing a ≥7 mm follicle detected by ultrasound were selected (n = 91). Follicular wave was synchronized by injecting 5 mg of LH and then, the presence of a dominant follicle ≥7 mm was determined 12 days later through ultrasound evaluation. Alpacas were assigned to one of six experimental groups: G1 (n=16) seminal plasma (SP) by intramuscular injection – i.m.; G2 (n=15) phosphate-buffered saline (PBS) i.m.; G3 (n=16) SP by intrauterine administration – i.u.; G4 (n=15) PBS i.u.; G5 (n=15) SP i.u. with curettage; G6 (14) PBS by i.u. with curettage. Ovulation rate and corpus luteum were determined by ultrasound evaluation on D2 and D8 (D0 = day of treatment). Serum samples were taken from the jugular vein on D0, D3 and D9 to determine progesterone profiles by radioimmunoassay. Ovulation rate was 93.7, 37.5, and 66.5% for G1, G3 and G5 respectively, while none ovulations were observed in the other three groups. Alpacas in G1 would produce 25 more ovulations than G3. Results of the present study suggested that the ovulation-inducing factor (OIF) present in seminal plasma is absorbed systemically and that the mechanical action of curettage would contribute to the absorption of the OIF present in seminal plasma.
El estudio tuvo por objetivo evaluar el sitio de deposición del plasma seminal sobre la tasa de ovulación y formación del cuerpo lúteo en alpacas. Se seleccionaron 91 hembras no lactantes con folículos ≥7 mm detectados por ecografía transrectal. Se sincronizó la onda folicular con la aplicación de 5 mg de LH, y 12 días después, se determinó la presencia de un folículo dominante (≥7 mm). Las hembras se distribuyeron al azar en seis tratamientos: G1 =16 (Plasma seminal vía intramuscular), G2=15 (PBS vía intramuscular), G3=16 (Plasma seminal vía intrauterina), G4=15 (PBS vía intrauterina), G5 =15 (Plasma seminal vía intrauterina con curetaje), G6 =14 (PBS vía intrauterina con curetaje). La tasa de ovulación y presencia de cuerpo lúteo se determinó mediante ecografía el día D2 y D8 (D0 = inicio del tratamiento). Se tomó muestras de sangre los días D0, D3 y D9 para determinar perfiles séricos de progesterona mediante RIA. La tasa de ovulación fue de 93.8, 37.5 y 66.5% para G1, G3 y G5, respectivamente, y no se registraron ovulaciones en los otros grupos. Se encontró que las alpacas G1 producirían 25 veces más ovulaciones con respecto al G3. Los resultados sugieren que la absorción del factor inductor de ovulación (FIO) del plasma seminal es vía sistémica y que el curetaje facilitaría la absorción del FIO incrementando el efecto ovulatorio del plasma seminal.
