Layer‐by‐layer soft‐tissue effects on flexion–extension‐dominant passive ex vivo limb joint ROM in quadrupedal mammals: An anatomical contribution to a morphofunctional framework

Journal of Anatomy, EarlyView.
Layer‐by‐layer passive ex vivo assessment of flexion–extension‐dominant limb joint ROM across rabbit, pudu deer, chilla fox and pig revealed joint‐, tissue‐ and taxon‐specific responses to progressive tissue removal. Proximal joints often showed increasing ROM, whereas distal joints often showed non‐monotonic responses.

Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

Veterinary Record, Volume 199, Issue 7, Page e327-e330, 3/10 October 2026.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

Malignant Hyperthermia in Alpaca (Vicugna pacos)

Acta Scientiae Veterinariae
Background: Malignant hyperthermia (MH) is a metabolic myopathy that affects several species, including humans; it occurs because of a sudden increase in calcium in the muscle fibers in genetically susceptible individuals. In camelids, such as alpacas, it is related to heat stress, caused, for example, by an environment with high temperatures. However,

Modeling the impacts of grazing management on livestock behavior and performance: A case study in the Peruvian Andes

Grassland Research, Volume 5, Issue 3, Page 270-283, September 2026.
Our modeling study shows that livestock management strongly influences grazing behavior and animal performance in the Peruvian Andes. Furthermore, adjusting stocking rates and improving animal distribution can enhance forage intake and body condition while increasing forage biomass.

Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

Grassland Science, Volume 72, Issue 3, Page 163-174, July 2026.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

ASIP Variants in Livestock: It's Not Black and White

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Fur and feather pigmentation play an important role in the survival and reproduction of many species, as well as in selective breeding and agriculture. The synthesis of pigment molecules, eumelanin and pheomelanin, is partially regulated by the agouti signalling protein (ASIP) encoded by the ASIP gene.

Sistemática, taxonomía y domesticación de alpacas y llamas: nueva evidencia cromosómica y molecular Systematics, taxonomy and domestication of alpaca and llama: new chromosomal and molecular evidence

Revista Chilena de Historia Natural, 2007
Existen cuatro especies de camélidos sudamericanos, dos de ellos silvestres, guanaco (Lama guanicoe) y vicuña (Vicugna vicugna), y dos formas domésticas, alpaca (Lama pacos) y llama (Lama glama), cuyo origen ha sido objeto de debate.
