El presente trabajo de investigación se llevó a cabo en el Laboratorio de Reproducción Animal de la Facultad de Medicina Veterinaria y Zootecnia de la Universidad Nacional del Altiplano-Puno. Ubicado a una altitud de 3820 m.s.n.m. y geográficamente a una Latitud sur de 15º49′34.5″ y una longitud oeste de 70º 00′ 43.5″ en la meseta del Collao. El objetivo principal fue Determinar el porcentaje de producción de embriones in vitro a partir de los ovocitos aspirados de los ovarios de vacas sacrificadas en el camal, dentro una incubadora portátil. Para la maduración, fertilización y producción de embriones a partir de los ovocitos aspirados de los ovarios, se utilizó una incubadora portátil que se adecuo un taper de plástico que tenía las siguientes medidas largo= 16 cm, ancho= 11 cm, alto= 5.8 cm con un volumen total de 500 mL, al taper se le acondiciono en la tapa una...

The objective was to determine the addition of 5% carbon dioxide (CO2) from effervescent granules or gasified to a portable incubator (taper) to evaluate the in vitro production of embryos of oocytes aspirated from ovaries of cows slaughtered in the slaughterhouse and evaluate viability in vivo through pregnancy in recipient cows. As a portable incubator, a 500 cm3 plastic taper was used, to which a valve for controlling the addition of CO2 was conditioned. The maturation was carried out for 24 h, fertilization for 18 h and embryo culture for 7 d in 500 uL of the media in petry plates and introduced into the portable incubator, which was placed in a water bath at 38.5 ° C. At 72 h post fertilization the proportion of zygotes was determined, at 7 d post culture the embryos were counted. The fertilization results with the addition of CO2 from effervescent granules was 38.28...
