Multiple follicular cysts in four alpacas (Vicugna pacos)

Veterinary Dermatology, 2010
AbstractFollicular cysts are non‐neoplastic skin lesions lined by follicular epithelium. The pathogenesis of these lesions is unclear. Multiple follicular cysts occur sporadically in dogs, horses and humans and are common in sheep. Here we report multiple follicular cysts in four aged alpacas (Vicugna pacos).

Leptin and IGF1 receptors in alpaca (Vicugna pacos) ovaries

Animal Reproduction Science, 2019
Folliculogenesis and ovulation are regulated by gonadotrophins and other factors such as Insulin like growth factor 1 (IGF1) and leptin. In various species the presence of IGF1 receptor (IGF1R) and leptin receptor (ObR) has been detected in the ovary, but not in the alpaca.

Multiple congenital anomalies in an alpaca cria ( Vicugna pacos )

Veterinary Record, 2010
PHYSICAL anomalies in South American camelids in the USA are thought to have arisen as a result of the considerable degree of inbreeding and absence of genetic diversity within the population. Congenital defects have the potential to cause economic loss, and those that are genetic in origin and ...

76. Cryocapacitation of Alpaca (Vicugna pacos) sperm cell

Cryobiology, 2012
The process of sperm cryopreservation is widely used in the programs of assisted reproduction and genetic improvement of many species. One of the features in the cryopreservation process is a disturbance at the plasma membrane which leads to a premature acrosomal reaction and phosphorylation in tyrosine residues of many proteins, as well as declining ...

Pregnancy Length, Offspring Weight and Birth Outcomes in Alpaca (Vicugna pacos): An International Survey.

Reproduction in domestic animals = Zuchthygiene
Alpaca gestation lasts approximately 11.5 months, but significant variation exists, and contributing factors are poorly described. This study aimed to conduct an international survey to assess pregnancy length (PL), based on geographical location.

TOXOPLASMOSIS-ASSOCIATED ABORTION IN AN ALPACA (VICUGNA PACOS) FETUS

Journal of Zoo and Wildlife Medicine, 2014
A near-full-term alpaca (Vicugna pacos) was stillborn 2 days before the expected date of delivery; necropsy examination was conducted within 6 hr of delivery. Gross lesions were enlarged liver and hydrocephalus. On histologic examination, mild inflammatory lesions were identified in the placenta, liver, and lungs, although no etiology was recognized ...
