Reproducción de bovinos criollos hembras con potencial fenotípico mediante transferencia de embriones a tiempo fijo en el cantón Saraguro.

Abstract

Abstract:The programs, projects that have been carried our in the territory by public and private institutions in genetics specifically Artificial Insemination, have not generated the transcendental impact on dairy farming, being the susbsistence and flow of capital, the constant in the live stock reality of small and medium producers.These genetic improvement models have been run for decades without generating an ideal and applicable model of low-cost milk production. Genetic improvement focused on foreign animals not adapted to local management and nutrition, generates problems for producers in the short, long and medium term. The transfer of embryos in female bovine creole animals with dairy genetic potential woild reduce genetic improvement by up to four generations, being the alternative in sustainable live stock production. Faced with this, ir is proposed to carri out a study that determines whether the TE of donors with milk production greater than 1 4 liters in just 1 milking , will improve milk production taking into account that the F1 obtained will have 50 % of genetics adapted to agroecological conditions, nutrition and extensive management that producers carry out.
