    • Alpaca semen characteristics previous to a mating period 
      Flores, Paloma; García Huidobro, Jorge; Muñoz, Camila; Bustos Obregón, Eduardo; Urquieta, Bessie (ELSEVIER SCIENCE BV, 2002-08-15)
      Increasing the knowledge of the semen characteristics in the alpaca will contribute to understanding one of the many factors that affect the poor fertility rate in this species. Ten adult male alpacas, 2.6-10 years of age, ...
    • Alpaca semen characteristics under free and directed mounts during a mating period 
      Urquieta, Bessie; Flores, Paloma; Muñoz, Camila; Bustos Obregón, Eduardo; García Huidobro, Jorge (ELSEVIER SCIENCE BV, 2005-12)
      Most studies in alpaca reproductive biology have been focused on female physiology. Only recent research is being conducted in order to increase the knowledge on males. Semen characteristics during breeding periods will ...
    • Biological activity of the seminal plasma of alpacas, stimulus for the production of LH by pituitary cells 
      Paolicchi, Fernando; Urquieta, Bessie; Cabrera del Valle, Luis Alejandro; Bustos Obregón, Eduardo (ELSEVIER SCIENCE BV, 1999-01-08)
      South American camelids are induced ovulators and require a stimulus to trigger the LH surge responsible for the ovulation. Seminal plasma (SP) of fertile alpacas (Lama paces) was tested using a bioassay of pituitary cells ...
    • Distribution of keratins, vimentin, and actin in the testis of two South American camelids: Vicuna (Vicugna ...
