Evaluation of fertility and subfertility in adult alpacas and tuis using ultrasonography, endometrial cytology and bacterial isolation [PDF]

SPERMOVA, 2020
The objective of this study was to compare the uterine health between fertile, sub-fertile alpacas and tuis using transrectal ultrasonography, endometrial cytology and bacterial isolation.

Blood selenium and zinc concentration of female alpacas (Vicugna pacos) and their offspring during different physiological conditions

Open Veterinary Journal, 2023
Background: Minerals are important for animals in many biological functions. There is scarce information however about micromineral content in the blood of South American camelids under their prevalent production system.

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.

ASPECTS OF REPRODUCTION IN THE ALPACA [PDF]

Reproduction, 1968
Summary. The alpaca, Lama pacos, does not have regular oestrous cycles, but oestrus lasts for 21 to 36 days during the breeding season. Ovulation is induced by coitus. Follicular ovulation rupture occurs spontaneously 26 hr after coital stimulation and can be induced by a single injection of hcg.

Alpaca Field Behaviour When Cohabitating with Lambing Ewes

Animals, 2020
A common strategy to reduce predator attack on livestock is the deployment of guardian alpacas. However, little research has been conducted on the behaviour of this species while housed with other livestock.

Clinical and Histological Features of Ovarian Hypoplasia/Dysgenesis in Alpacas

Frontiers in Veterinary Science, 2022
Alpacas have a high incidence of congenital reproductive tract abnormalities, including ovarian hypoplasia/dysgenesis. Diagnosis of this condition is often challenging.

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.

Interaction between the melanocortin 1 receptor (MC1R) and agouti signalling protein genes (ASIP), and their association with black and brown coat colour phenotypes in peruvian alpaca

Italian Journal of Animal Science, 2020
The aim of this work was to assess the interaction between MC1R and ASIP genes in determining coat colour variation in black and brown Peruvian alpacas. Skin biopsies were collected from 25 black alpacas and 15 brown alpacas.

Polimorfismos de nucleótido simple (PNSs) del gen MC1R en alpacas negras y marrones

Revista Peruana de Biología, 2021
En alpacas los fenotipos del color de vellón tienen diferentes terminologías que induce a una confusión dentro del color marrón y sus tonalidades, el que requiere de una mejor descripción y cuantificación. En consecuencia los objetivos del estudio fueron
