dc.description | The present research was carried out in the livestock farm of the Faculty of Agricultural Sciences of the Technical University of Babahoyo in the province of Los Ríos, whose purpose is to evaluate the IAFT protocol, the effect of equine chorionic hormone (eCG) in two treatments, applied at the time of removing the intravaginal device impregnated with progesterone, hoping to improve pregnancy rates. It was carried out on 28 cows with body condition of 2.5 to 3.5, postpartum of 45 to 120 days. For T0 (n=14), which were administered, estradiol cypionate 1 ml, prostaglandin 2 ml and 500 I.U. of equine chorionic hormone, and the remaining control group T1 (n=14) was applied 1 ml of estradiol cypionate, 2 ml of prostaglandin and 300 I.U. Pregnancy was confirmed by a gynecological examination with an ultrasound 30 days after insemination. The statistical analysis carried out in this study, the pregnancy rates for the two treatments, the T1 500 IU achieved the highest pregnancy result with 42.86%, which represents 6 cows of the 14, compared to the T0 300 IU control cows with 21.43%, which represents 3 cows of the 14 in which insemination was carried out, on the other hand, the economic viability of both treatments together with the percentage difference between them in the treatment with the best cost was T1 500UI (with eCG) having Economic returns from each dollar invested we earn 0.31 dollars considering that the offspring resulting from insemination will be sold immediately. | es_ES |

dc.description.abstract | La presente investigación se realizó en la ganadería de la Facultad de Ciencias Agropecuarias de la Universidad Técnica de Babahoyo de la provincia de Los Ríos, cuya finalidad es evaluar protocolo de IAFT, el efecto de la hormona coriónica equina (eCG) en dos tratamientos, aplicada al momento de retirar el dispositivo intravaginal impregnado de progesterona, esperando mejorar los porcentajes de preñez. Se realizó a 28 vacas con condición corporal de 2,5 a 3.5, postparto de 45 a 120 días. Para el T0 (n=14) las cuales se administraron, cipionato de estradiol 1 ml, prostaglandina 2 ml y 500 U.I. de hormona coriónica equina, y el grupo testigo T1 (n=14) restante se aplicó cipionato de estradiol 1 ml, 2 ml de prostaglandina y 300 U.I. la preñez se comprobó mediante un examen ginecológico con ecógrafo 30 días post inseminación. El análisis estadístico realizado en este estudio, las tasas de preñez para los dos tratamientos, el T1 500 UI alcanzo el mayor resultado de preñez con 42,86% que representa 6 vacas preñadas de las 14, en comparación con el T0 300 UI vacas testigos con el 21,43% que representa 3 vacas de las 14 a las cuales se les realizó la inseminación, en cambio la viabilidad económica de ambos tratamientos junto con la diferencia porcentual entre ellos en el tratamiento con mejor costo fue T1 500UI (con eCG) teniendo réditos económicos de cada dólar invertido ganamos 0,31 dólares considerando que las crías producto de inseminación se venderán inmediato. | es_ES |
