A Review of Infectious and Non‐Infectious Causes of Pregnancy Loss in Goats

Reproduction in Domestic Animals, Volume 61, Issue 3, March 2026.
ABSTRACT Goats play a vital role in global agriculture, particularly in developing regions, and are increasingly kept as companion animals. Given their economic and social importance, pregnancy losses in goats represent a substantial challenge, leading to considerable economic losses and raising concerns about animal welfare and public health, as some ...

Effect of Cooling and Freezing on Llama (Lama glama) Sperm Ultrastructure

Frontiers in Veterinary Science, 2020
Semen cryopreservation in South American camelids has a low efficiency. Post-thaw viability of sperm is low, and poor results are obtained when artificial insemination is performed with cryopreserved semen, impeding advances both in accelerated genetic ...

Survey on shedding of selected pathogenic, zoonotic or antimicrobial resistant bacteria by South American camelids in Central Germany

Berliner und Münchener Tierärztliche Wochenschrift, 2022
South American camelids (SAC) are increasingly popular in Germany. Although frequently in close contact to livestock and humans, data on the prevalence of epizootic and zoonotic bacteria and of bacteria exhibiting antimicrobial resistance (AMR) in SAC is

New Insights Into the Role of β-NGF/TrKA System in the Endometrium of Alpacas During Early Pregnancy

Frontiers in Veterinary Science, 2021
One striking reproductive feature in South American camelids is that more than 90% of gestations are established in the left uterine horn (LUH). This phenomenon could be related to a differential vascular irrigation of the LUH.

Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
Wild South American camelids—vicuña and guanaco—face threats from sarcoptic mange, a contagious skin disease linked to severe population declines. Despite its impact, major gaps remain in understanding disease dynamics. This review summarizes current knowledge, identifies key data and management gaps, and outlines urgent actions for effective ...

In vivo e in vitro embryo production in South American camelids [PDF]

, 2012
En los camélidos sudamericanos (CSA), la producción de embriones in vivo se puede realizar a partir de un folículo dominante presente en el ovario de la hembra donante o se puede inducir el crecimiento folicular múltiple para aumentar el número de ...

Production, Preservation, and Transfer of South American Camelid Embryos [PDF]

Frontiers in Veterinary Science, 2017
La présente revue résume les progrès réalisés dans le domaine de la production in vitro et in vivo d'embryons de camélidés d'Amérique du Sud. Les deux méthodes nécessitent une superstimulation ovarienne (avec FSH et eCG) pour obtenir des ovulations multiples (production d'embryons in vivo) ou pour induire la croissance folliculaire pour la collecte d ...

Native and Alien Ungulates in North America: Potential for Restoring Herbivore Diversity and Functions

Global Ecology and Biogeography, Volume 35, Issue 1, January 2026.
ABSTRACT Aim Large herbivores play key roles in ecosystems by promoting plant diversity, dispersing seeds, regulating nutrient cycling, and shaping vegetation structure. Since the Late Pleistocene, their declines have led to profound ecosystem changes. While often viewed as problematic, alien herbivores may partly compensate for these losses; yet their
