Efecto de minerales inyectables en los porcentajes de preñez en vacas mestizas de la Universidad Técnica de Babahoyo

At the Technical University of Babahoyo, the effect of supplementation with injectable minerals on pregnancy percentages in crossbred cows was evaluated. The total population of cattle at the Faculty of Agricultural Sciences is 90 animals, of which 24 viable cows were selected for the experiment, with a body condition between 2.5 and 3.5. The experimental protocol included the application of an intravaginal device impregnated with progesterone, followed by the administration of estradiol benzoate, and subsequent artificial insemination of the cows. Twelve of the cows also received supplementation with 15 ml of injectable minerals on days 0, 7 and 14, constituting the treatment group. The other 12 cows, which did not receive minerals, made up the control group. The statistical analysis performed (ANOVA) did not show significant differences between the treatments (P. Value > 0.05). However, numerical results indicated that cows in the group that received mineral supplementation were 16% more pregnant compared to the control group, suggesting a favorable trend towards the use of mineral supplementation. The Tukey test also showed an arithmetic mean pregnancy rate of 58% for the group with minerals and 42% for the group without minerals. This research requires additional studies with a larger sample size or under different conditions to confirm its effectiveness.
