dc.description.abstract | Esta investigación se llevó a cabo para determinar el efecto de la exposición al macho cabrío sobre la respuesta al estro, el inicio del estro permanente, la tasa de ovulación, la tasa de concepción y la tasa de preñez en cabras sincronizadas con esponjas de acetato de medroxiprogesterona (MAP). Se colocaron esponjas dentro de la vagina durante quince días en grupos aislados y expuestos a machos. Después de retirar la esponja, se observaron continuamente las actividades estrales. El intervalo entre la retirada de la esponja y el inicio del estro permanente fue de 32.3±10 h (18-51 h) y 45.2±10.9 h (27-51 h) en el grupo de machos aislados y expuestos respectivamente (p<0.05). Las tasas de ovulación y concepción se confirmaron mediante el nivel de progesterona sérica mediante radioinmunoensayo. Las tasas de ovulación fueron del 100% en ambos grupos y las tasas de concepción fueron del 93% y del 100% en los machos expuestos y en el grupo aislado, respectivamente (p>0.05). Los embarazos fueron confirmados por ultrasonido en el día 35 después del apareamiento, que fueron 93%, fue y 69% en el grupo expuesto y aislado de machos, respectivamente (p>0.05). Sobre la base de la evidencia, se infirió que la exposición repentina al macho después de la extracción de la esponja provocó un inicio del estro notablemente más temprano, mientras que la exposición continua al macho no pudo mostrar un impacto significativo en las tasas de concepción y preñez en comparación con el grupo aislado. | |
dc.description.abstract | This investigation was executed to determine effect of buck exposure on estrus response, onset of standing estrus, ovulation rate, conception rate and pregnancy rate in goats synchronized with medroxyprogesterone acetate (MAP) sponges. Sponges were placed inside the vagina for fifteen days in buck exposed and isolated groups. Post sponge withdrawal, estrus activities were continuously observed. The interval between sponge withdrawal and the onset of standing estrus were 32.3±10 h (18-51 h) and 45.2±10.9 h (27-51h) in buck isolated and exposed group respectively (p<0.05). Ovulation and conception rates were confirmed by serum progesterone level using radioimmunoassay. Ovulation rates were 100% in both groups and conception rates were 93% and 100% in buck exposed and in isolated group respectively (p>0.05). Pregnancies were confirmed by ultrasound on day 35 post mating which were 93%, was and 69% in buck exposed and isolated group respectively (p>0.05). Based upon the evidence, it was inference that post sponge removal sudden buck exposure cause markedly earlier estrus onset while the continuous buck exposure was unable to show significantly impact on conception and pregnancy rates compare to isolated group. | |
