Follicular activity and hormonal secretory profile in vicuna (Vicugna vicugna)

Theriogenology, 2004
The objective of the present study was to characterize ovarian activity in non-mated vicunas, relating ovarian structures (evaluated by transrectal ultrasonography, daily for 30 days) to changes in plasma concentrations of estradiol-17beta and progesterone.

Fibre characteristics of vicuña (Vicugna vicugna mensalis)

Small Ruminant Research, 2010
Abstract Characteristics of body and fleece weight, and fleece and fibre quality were evaluated in vicunas ( Vicugna vicugna mensalis ) captured for live shearing in Huancavelica, Peru. A total of 305 animals were weighted and shorn between 2003 and 2008. Fibre samples from 104 animals shorn in 2008 were analysed using optical fibre diameter analyser

Vicugna vicugna (Vicuna)

1967
One animal of each sex (Catskill Game Farm, Catskill, New York, USA) was studied by the lymphocyte technique. Many elements are difficult to classify (subtelocentrics or acrocentrics); however, the karyotypes are similar to other camelidae published in that seven pairs of small metacentric chromosomes can readily be distinguished.

Aspects of play behaviour of vicuña, Vicugna vicugna

Small Ruminant Research, 1994
Abstract Calves and yearling vicunas (Vicugna vicugna) were observed in the INTA-Abrapampa, Jujuy, Argentina. Vicunas played more early in the morning and late afternoon, and generally play behaviour was performed between two animals belonging to the same family. About 20% of playing included calves from different families.

The vicuna (Vicugna vicugna) as a natural host of Dictyocaulus filaria in Peru

Parasitology International
Lungworm infection, or verminous pneumonia, is a parasitic disease that causes serious problems in small and large ruminants. Despite the fact that nematodes of the genus Dictyocaulus in cattle and sheep are the main cause of this disease, there are few studies on the natural infections of South American camelids.

Mitochondrial DNA (mtDNA) genetic diversity of Vicugna vicugna mensalis in Bolivia

2011
The vicuna (Vicugna vicugna) is one of two wild South American camelids. Nowadays in Bolivia, there are over 62,869 animals representing 20% of the world’s population breeding in the wild as the only management system. Two subspecies of vicuna are currently accepted, based largely on genetic and size differences: Vicugna vicugna vicugna, distributed in
