Evaluación de tasa de gestación por medio de protocolo de inseminación artificial a tiempo fijo y resincronización en búfalas de agua (Bubalus bubalis) en la zona sur del lago Maracaibo Venezuela.

Abstract

This study was carried out at Búfalos del Sur Agropecuaria, hacienda las delicacies located in Santa Bárbara del Zulia (Venezuela). Where a batch of 30 buffaloes was used, which were in rotational grazing with the same nutritional and environmental conditions, the body condition was 3/5 on average. The reproductive check was carried out, discarding any pathological anomaly that could interfere with the work to be carried out and the follicular dynamics was also evaluated. The protocol to be implemented in this studio goes from day 0 ending on day 12 where TAI is performed, on day 0 it starts with the administration of 2.5 ml of GnRH via deep intramuscular route producing at the hypothalamic pituitary level the release of LH and FSH causing the ovulation of the dominant follicle or luteinization and thus setting up a new follicular wave, the introduction of an intravaginal device (IBD) impregnated with exogenous progesterone. On the 23rd, resynchronization is carried out on the entire batch of buffaloes, which is being carried out, restarting the protocol from day 0, but I have in mind that the use of the intravaginal device (DIB) is not used. I carry out a reproductive check at 33 days after the IATF where the empty buffaloes were separated from the preñadas, continuing the process with the vacancies. This information will be used to evaluate the gestation rate since the first IATF and the resynchronization being the main objective of the work.
