dc.descriptionThis research was carried out in the cattle farm of the Faculty of Agricultural Sciences of the Technical University of Babahoyo, after starting this work two groups of 14 animals were formed, both groups received a vaginal device impregnated with progesterone and an additional 2 ml of estradiol benzoate, after 7 days, the intravaginal device was removed and 1 ml of estradiol cypionate was administered, 2 mL of prostaglandin and 400 IU of equine chorionic hormone for 52 hours, which that further promotes ovulation, then, 14 days after artificial insemination, 2 ml of progesterone was injected, which helps the gestation process, strengthens the corpus luteum and contributes to improving the gestation rate. Group 2, consisting of 14 cows, was given progesterone to assess higher pregnancy rates, as the same protocol was used in both groups of cows. A completely randomized experimental design with two treatments (hormone progesterone) and 14 replications, comparisons of treatment means will be made with Tukey's test at 5% probability, the best treatment was with the application of injectable progesterone obtaining a result of 42.86% while treatment without injectable progesterone resulted in 21.43%. In conclusion, it was found that it was necessary to use progesterone in the form of injections, since in the experimental group a higher pregnancy rate was observed in crossbred cows in the Faculty of Agricultural Sciences.es_ES

dc.description.abstractEsta investigación se realizó en la finca ganadera de la Facultad de Ciencias Agrícolas de la Universidad Técnica de Babahoyo, luego de iniciar este trabajo se formaron dos grupos de 14 animales ambos grupos recibieron un dispositivo vaginal impregnado de progesterona y 2 ml adicionales de benzoato de estradiol, después de 7 días, se retiró el dispositivo intravaginal y se administró 1 ml de cipionato de estradiol, 2 ml de prostaglandina y 400 UI de hormona coriónica equina durante 52 horas, lo que favorece aún más la ovulación, luego, 14 días después de la inseminación artificial, se inyecto 2 ml de progesterona, que ayuda al proceso de gestación, fortalece el cuerpo lúteo y contribuye a mejorar la tasa de gestación. Al grupo 2, formado por 14 vacas, se le administró progesterona para evaluar tasas de preñez más altas, ya que se utilizó el mismo protocolo en ambos grupos de vacas. Para diseñar este estudio se utilizó un diseño experimental completamente al azar con dos tratamientos (hormona progesterona) y 14 repeticiones, las comparaciones de las medias de tratamiento se efectuarán con la prueba de Tukey al 5 % de probabilidad, el mejor tratamiento fue con la aplicación de progesterona inyectable obteniendo un resultado de 42.86% mientras que el tratamiento sin progesterona inyectable dio como resultado 21.43%. En conclusión, se encontró que era necesario utilizar progesterona en forma de inyecciones, ya que en el grupo experimental se observó una mayor tasa de preñez en las vacas mestizas en la Facultad de Ciencias Agropecuarias.es_ES
