Pharmacokinetics of ivermectin in llamas ( Lama glama )

Veterinary Record, 2002
The pharmacokinetic behaviour of ivermectin was investigated in adult llamas ( Lama glama ) by using high performance liquid chromatography with a lower limit of quantification of 2 ng/ml to measure its concentration in serum.

Superovulatory responses to eCG in llamas (Lama glama ).

Theriogenology, 1995
Llamas are copulation-induced single-ovulators, and multiple ovulation and embryo transfer (MOET) methods have not yet been developed for this species. Superovulatory responses to eCG given during an induced (Group A) or simulated (Group B) luteal phase were investigated using ultrasound to observe ovarian follicles and corpora lutea (CLs) and plasma ...

Somatic Sensory Cortex of Llama (Lama glama)

Brain, Behavior and Evolution, 2008
The somatic sensory cortex (SI and SII) was mapped in llamas using microelectrode mapping methods developed earlier in a study of SI of the slow loris. Projections to SI from the llama''s prehensile browsing lips were differentially enlarged when compared to those reported for sheep.

Coccidia of the llama, Lama glama, in Colorado and Wyoming

Veterinary Parasitology, 1991
Fecal samples were collected from 144 llamas, Lama glama, on four premises in northern Colorado and southern Wyoming. Feces were examined for the presence of coccidial oocysts; Eimeria alpacae was found in 55.6%, Eimeria lamae in 67.3% and Eimeria macusaniensis in 1.4% of the samples.

Cryopreservation of Llama (Lama glama) Semen

Reproduction in Domestic Animals, 1999
ContentsIn order to test two extenders, and the effect of the addition of a surfactant and different freezing rates for cryopreservation of llama semen, the motility (MOT) and the integrity of acrosomes (NA) of 11 frozen ejaculates, collected with artificial vaginas from three llama males, were recorded.

Granulosa cell tumour in a llama (Lama glama)

Reproduction in Domestic Animals, 2022
AbstractHormonally active tumours are characterized by production and secretion of hormones, irrespective of endogenous feedback mechanisms. An adult llama had exuberant oestrous behaviour, infertility, elevated concentrations of oestradiol and a large ovarian mass.

[Capillaries of the myocardium of Lama (Lama glama)].

Berliner und Munchener tierarztliche Wochenschrift, 2001
The heart of 12 adult llamas, one female and 11 males, 2-7 years of age, was studied gross-anatomically (absolute and relative heart weight) and microscopic-anatomically (left and right ventricular wall, left auricle). Comparing the 9 younger animals (2-3 years old) with the 3 older llamas (5-7 years old) a significant increase of the absolute heart ...

Pulmonary Neoplasia in Two Llamas (Lama glama)

Veterinary Pathology, 2004
Two llamas with pulmonary tumors were examined. Llama No. 1 had multiple nodules throughout the lung that consisted histologically of solid clusters of polygonal to spindle cells with rare glandular differentiation. Intravascular emboli were common. Similar neoplastic masses were present in the kidney, heart, and liver.

Parasite‐induced leucomyelopathy in llamas ( Lama glama )

Veterinary Record, 2008
Parelaphostrongylus tenuis , a protostrongylid nematode, is a recognised cause of ataxia and recumbency in llamas in North America ([Fowler 1998][1]). This short communication describes a similar nematode infestation associated with ataxia and recumbency in an adult llama, and a possible case in ...

Ultrasonography as an aid to controlled breeding in the llama (Lama glama)

Veterinary Record, 1992
An ultrasonic linear array scanner with a transrectal probe was used to observe ovarian and uterine changes associated with the reproductive cycle in llamas. 'Waves' of follicular development and regression occurred in unstimulated females, during which the dominant follicle reached a maximum size of 9 to 13 mm; both ovaries were equally active ...
