Efecto de Cuatro Diluciones de Plasma Seminal sobre la Tasa de Ovulación, Tamaño de Cuerpo Lúteo y Perfil de Progesterona en Alpacas

Abstract: RESUMENEl estudio tuvo como objetivo evaluar el efecto de cuatro diluciones de plasma seminal sobre la tasa de ovulación y formación de cuerpo lúteo en alpacas. Se seleccionaron 44 alpacas sin cría al pie y con la presencia de un folículo dominante >7 mm detectado por ecografía transrectal. Los animales se distribuyeron al azar en cinco grupos experimentales: G 1 , plasma seminal (PS) diluido 1:1 (v/v) con fosfato salino bufferado (PBS); G 2 , PS diluido 1:2 (v/v) con PBS; G 3 , PS diluido 1:4 (v/v) con PBS; G… Show more

“…Briefly, each ejaculate was very slowly aspirated and expelled (avoiding foam formation) with a needle (0.5 mm inner diameter) attached to a syringe, repeating this action 10 times. Then, the ejaculates were centrifuged at 700 × g for 30 min ( 10 ), and the supernatant was recovered and centrifuged once again. SP was then recovered, and a drop was evaluated by microscopy to confirm the absence of cells ( 32 ).…”

“…Working with Bactrian camel semen, the ejaculates were treated with a magnetic stirrer at low speed (100 rpm) for 5 min ( 8 ), providing a liquefied homogenous specimen. Recently, the combination of the slow mechanical method (aspirating and expelling with a syringe or pipette) with low gravity acceleration (700 × g) allows obtaining SP without sperm cells [( 9 ) for llamas; ( 10 ) for alpacas], avoiding the possible expelling of fluids (including proteins) from the damaged spermatozoa.…”

“…De acuerdo con Tanco et al (2011), 1/200 va parte de la concentración total del FIO de un eyaculado promedio, correspondiente a 60 μg de OIF purificado, es la dosis mínima que una vez administrada vía IM, induce una buena tasa de ovulación y el consiguiente buen desarrollo del cuerpo lúteo. Reyna (2013), encontró que la dilución 1:8 (vol./vol.) de plasma seminal de alpaca en PBS, es la dilución mínima para producir ovulación.…”
