Effect of single dose follicle stimulating hormone on follicular aspiration, in...
Moraes, Mayara Ellen Bardi de; Adona, Paulo Roberto; Guemra, Samuel; De Bem, Tiago Henrique Camara; Miranda, Moysés dos SantosO presente estudo avaliou vacas Brangus tratadas com doses únicas de hormônio folículo estimulante (FSH) submetidas a aspiração folicular após vinte e quatro horas, para avaliação da recuperação oocitária, fertilização in vitro e taxa de prenhez. Folículos superiores a três milímetros de diâmetro foram aspirados, 200 mg de FSH foram administrados dois dias depois e uma nova aspiração folicular foi realizada 24 ...
In vitro embryos production of oocytes selected based on follicular size and by...
Barros, Fabiana Dakkach de Almeida; Adona, Paulo Roberto; Guemra, Samuel; De Bem, Tiago Henrique Camara; Monzani, Paulo Sergio; Leal, Claudia Lima VerdeWe evaluated the competence of bovine oocytes via morphological selection associated with follicular diameter and by brilliant cresyl blue (BCB) staining, in order to improve oocyte selection and the efficiency of in vitro embryo production. Follicles with small (2 < 4 mm), large (4–8 mm) or mixed (2–8 mm) diameters were aspirated from slaughterhouse ovaries. Next, the morphologically categorized oocytes wer...
