Evaluación del efecto de la progesterona en vacas mestizas post inseminación artificial para determinar preñez.

This 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.
