Evaluación de la viabilidad embrionaria en charolais Full French con la aplicación de dos diferentes protocolos de implantación.

Abstract

The objective was to evaluate embryonic viability in Full French charolais with the application of two different implantation protocols. The research has a quantitative and experimental approach that was analyzed and evaluated using the Chi square test, starting from the scarcity of work carried out on the use of GnRH as gonadorelin and buserelin in implantation protocols in in vivo embryo transfer, mainly to breeders of Charolais Full French breed cattle. In this experimental research, two analysis components were obtained, for which the initial population of 35 bovine females was used, of which 24 transferable recipients responded satisfactorily, which were divided into 2 groups of 12 experimental units (UE = female). The influence of GnRH recorded that the calculated X2 statistic is less than the theoretical effectively in embryo implantation. It is concluded that the success of embryo implantation is directly related to the size of the corpus luteum, body development and the choice of crossbred cows. Regarding the cost benefit, it was determined that the best result was obtained with the application of treatment T1, since the cost benefit ratio was 1.27, meaning that for every dollar invested there is a benefit of 27 cents and with the application of the treatment two, it is not possible to recover the dollar invested since the sales price is lower than the production cost. It is recommended to carry out more combined research with interferon tau, higher doses of GnRH treatment and the addition of glycoline before and after the implantation protocol.
