Birth of live llama (Lama glama) derived from embryo transfer storage at 5 °C for 24 h
(2015-11)The objective of the present work was to evaluate the efficacy of maintaining llama embryos metabolically inhibited but viable at 5 °C during 24 h. Adult females (n = 20) were used as embryo donors and were superstimulated ... -
Embryo yield in llamas synchronized with two different intravaginal progesterone-releasing devices and superovulated with eCG
(2015)The objectives of this study were to compare the effects of two intravaginal devices (ID) containing the same dose (0.5 g) of progesterone (P4) on subsequent ovarian response, embryo production and circulating P4 concentration ... -
Llama (Lama glama) semen collection via thermo-electric artificial vagina: effect of seasonality and collection interval on ejaculate characteristics
(Elsevier, 2015-09-09)Adult male Llamas (Lama glama) (n = 6) were collected using a receptive female and a thermo-electric artificial vagina assembled with a polyethylene collection bag with the following objectives: (a) to develop a reliable ... -
Mortality of a captive axis deer (Axis axis) and a llama (Lama glama) due to ingestion of Wedelia glauca
(Sage Publications, 2012-09)The current study describes a naturally occurring cluster of cases of Wedelia glauca intoxication. Seven of 14 axis deer (Axis axis) and 1 of 8 llamas (Lama glama) in a zoo of Buenos Aires province, Argentina, died suddenly ... -
Plasma steroid profiles and ovarian response in llamas treated with eCG for superovulation combined with exogenous progesterone during early luteal phase
(Elsevier, 2019-09)The objective of this study was to evaluate the effects of plasma progesterone (P4) concentrations during eCG-ovarian follicular superstimulatory treatment performed in early luteal phase and estradiol concentrations during ...
