Ultrasound dilution cardiac output and echocardiography findings in anesthetized mature alpacas (Vicugna pacos) during normotension, hypotension and hypertension.

PLoS ONE, 2023
Alpacas (Vicugna pacos) have physiologic adaptations to live at high altitude. These adaptations may result in unexpected responses to changes in cardiac performance and blood pressure during general anesthesia.

EVALUATION OF TWO CULTURE MEDIA IN IN VITRO PRODUCTION OF ALPACA (Vicugna pacos) EMBRYOS [PDF]

SPERMOVA, 2021
The present study aims to evaluate the effect of two culture media on the production of in vitro embryos in alpacas (Vicugna pacos). The ovaries were transported at 10.52° C in 0.9% saline solution supplemented with gentamicin.
