Impact of eCG Hormone on Estrus Synchronization and Fertility in Dairy Cattle from Cochabamba

Abstract

Introduction: Dairy production is essential for the economy of Bolivia, but it faces significant challenges due to low fertility rates in bovines, limiting the sector's profitability and productivity. Reproductive biotechnologies, especially the use of equine chorionic gonadotropin (eCG), have proven effective in improving reproductive efficiency and increasing pregnancy rates. Objective: To evaluate the effectiveness of equine chorionic gonadotropin (eCG) in estrus synchronization protocols to improve pregnancy rates in dairy cattle at Granja Saavedra, under the environmental conditions of Cochabamba. Methods: The study was conducted using an experimental design with two groups of 20 cows each. The treatment group was administered eCG in combination with intravaginal devices, while the control group did not receive eCG. Results: The results showed a significant improvement in the pregnancy rate of the treated group (59%) compared to the control group. This protocol helps optimize fertility, reduce open days, and increase the profitability of dairy production.
