Una posible causa de la variación de las tasas de concepción es la alta incidencia de pérdida embrionaria completa o falla en la fertilización en ovejas que son inducidas a ovular después del tratamiento con PMSG para promover una alta respuesta del estro (14).
Luego de inseminar artificialmente las cabras, el servicio por machos cabríos vasectomizados puede reducir la duración del estro, aumentando las tasas de concepción 7 .
La tasa de concepción es de 50 a 70% dependiendo de la época de inseminación, por lo que es baja en primavera y verano debido a una baja motilidad espermática, en comparación con la de otoño e invierno (2).
La inseminación por laparoscopía deposita los espermatozoides frescos o congelados-descongelados directamente en los cuernos uterinos, con una tasa de concepción del 80%.
En la Tabla 3 se exponen las tasas de concepción según el grado de dificultad a la IA.
