This research was conducted at the Catholic University of the Dry Tropics, located in Estelí, Nicaragua. The objective was to evaluate two methods of estrus synchronization with new and reused CIDR hormonal devices for transcervical artificial insemination in goats (Capra aegagrus hircus). A comparative quasi-experimental design was used. Among the treatments used are: T1 estrus synchronization with new CIDR hormonal devices for artificial insemination with fresh semen, T2 with reused CIDR for artificial insemination. In the variable Effectiveness of estrus synchronization methods, a Student's T test was applied, where the results obtained had no statistical differences. In the variable percentage of pregnancy, there was no statistical difference. In the benefit/cost variable, T1 highlights the reliability in the profitability component, obtaining a 1.04 with the RCB analysis. The results of the analysis of the variable: Proposal of reproductive management plan in UCATSE, it is concluded that areas of nutritional management and facilities for the implementation in goat reproduction using the methods of synchronization of estrus and artificial insemination should be reestablished, to obtain the increase in goat production.
