The study was designed to compare the cleavage and blastocysts rate of in vitro matured alpaca and llama oocytes after chemical activation. Alpaca (n=90) and llama (n=85) ovaries were collected at a local slaughterhouse and transported within 2-3 h to the laboratory. Cumulus oocyte complexes (COC...
We evaluated the effect of in vitro maturation time, sperm selection and oxygen tension on alpaca embryo development. In Experiment I, Cumulus Oocyte-Complexes (COCs) were obtained from abattoir ovaries and in vitro matured in TCM-199 for 24 (n = 217), 28 (215), or 32 h (223) at 38.5 degrees C, h...

Effect of oocyte maturation time, sperm selection method and oxygen tension on in vitro embryo development in alpacas
The ovulation-inducing effect of seminal plasma was first suggested in Bactrian camels over 30 years ago, initiating a long search to identify the 'ovulation-inducing factor' (OIF) present in camelids semen. During the last decade, primarily in llamas and alpacas, this molecule has been intensive...
