添加標簽 | 總結: | The present research work was carried out at Rancho 2 Potrillas, belonging to the Montalvo canton. Once the trial began, 2 groups were carried out in which group 1 used the application of an intra-vaginal device plus estradiol benzoate in 2.0 ml where we will have follicular waves in the reproductive system of the cow. After day 8, the device was removed and three equine chorionic hormones were applied, in a dose of 2 ml, Prostaglandin in a dose of 2 ml, and Estradiol Cypionate in a dose of 1 ml, which help promote greater ovulation. 52 hours after removal of the device, artificial insemination was carried out. In group 2, injectable progesterone (2 ml) was evaluated without the application of the device on day 0, while on day 8 the same hormones were applied waiting 52 hours to be inseminated (10 animals with intravaginal device and 10 animals with injectable progesterone). For the development of this research, the Completely Randomized experimental design was used, with two treatments (Progesterone Hormone and Control) and eight repetitions. Comparisons of treatment means will be made with the Tukey test at 5% probability. The conclusion determined that it is necessary to use the intra-vaginal device plus estradiol benzoate in 2.0 ml and the injectable progesterone hormone, since both obtained the same percentage of pregnancy in Jersey cows in the Montalvo canton. |
