Effect of genotype and sex on fiber growth rate of alpacas for their first year of fleece production

, 2014
The sale of alpaca fiber is the main income for thousands of families in the Central Andes of Peru. Little information exists on the fiber length growth rate of alpaca (FLG), especially throughout their first year of life when the fiber is most valuable.

Smart Ungulates: What Sheep and Goats' Performances in a Reversed‐Reward Contingency Task Tell Us About the Evolution of Cognitive Flexibility

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study shows that young goats outperform sheep in the reversed‐reward contingency task, which is a cognitive test requiring both inhibitory control and cognitive flexibility. The results highlight the importance of cognitive flexibility when solving this type of task, and suggest that the differences between both species may reflect social and ...

Thousands of Years of Pastoralism Don’t Count: Coprophagous Beetles Prefer Exotic Alpaca Dung to That of Cattle

Insects
Dung beetles mostly feed on mammal dung. Throughout the European Alps, the dung produced by local domestic ungulates attracts many species of dung beetles, giving rise to rich and diversified communities that play an important role in the Alpine ...

Effect of Short Tandem Target Mimic miR-5110 on Melanogenesis in Melanocytes of Alpaca (Vicugna pacos)

Current Issues in Molecular Biology
MicroRNAs (miRNAs) play important roles in the regulation of melanogenesis and coat color in mammals. Short tandem target mimics (STTMs) have been used to block the functions of small RNA in animals and plants.
