Utilización de prostaglandinas para sincronización de celos en yeguas con tres diferentes tipos de manejo

Abstract

Horses in different productions of the province of Chimborazo, located in different climatic zones (3400 m Chuquipogio hacienda, Tunshi Experiment Station - 2720 m and Rancho ESPOCH Emilios 2000 m), the presence of heat and pregnancy rate in mares performing evaluated different jobs, age and race due to the estrus synchronization with prostaglandins, using five mares per farm, with an animal as experimental unit and were chosen randomly from the group of existing non-pregnant mares. Experimental data were analyzed by Chi-square (X 2), in order to determine the independence or Prostaglandin vs Management.

Determine that the use of the present prostaglandin responses statistically similar, although numerically a change was observed in the last check of gestation where two mares showed no pregnancy. The differences between the responses are determined by the type of work they perform mares, that is mares receiving forced labor as the sport of Polo were not pregnant. Costs per mare / pregnant ($ 60.51), were determined in all the mares used for research, so it is recommended to synchronize estrus with prostaglandin employment because good results were obtained in pregnancy.
