This study found that melatonin implants at specific times of the year may increase cashmere production in young Australian cashmere goats by altering their growth cycles.

Adding bentonite clays to goat diets increased milk yield, periwinkle shell improved chicken egg production, and vaccination increased muscle area and carcass yield in calves.

Testosterone and fleece-flower root affect mouse hair growth.

This study found that repeated immunization against melatonin in Australian feral goats temporarily increased cashmere production and altered growth cycles, but these effects diminished after the first year.

In this study, researchers identified genes IRF2BP2 and EGFR as key to understanding double-coated fleece formation in Hetian sheep, offering insights that may advance machine learning-driven multi-omics selection models in sheep breeding.

This study found that in semi-coarse wool sheep of the Ukrainian Carpathian Mountain breed, changes in microflora and grease composition are linked to increased felting in wool, due to wetter, more alkaline fleece conditions that promote bacterial and mold growth and alter fatty acid balances.

This study conducted a genome-wide association analysis on 1,125 ewes and identified 24 SNPs associated with wool production traits, and highlighted potential candidate genes like ADAR and TP53 for further research into the genetic mechanisms influencing wool growth in sheep.

This study found that down and guard hairs of Inner Mongolia Cashmere Goats have distinct protein compositions and physical properties, with keratin-related proteins potentially influencing these differences.

This study suggests that changes in expressed transcripts and splice isoforms may explain the transition from curly to straight fleece in Chinese Tan sheep as they age.

This study found that miR-432 inhibits KRT83 expression, revealing potential molecular mechanisms for the formation of curly fleece in Tan sheep and suggesting implications for understanding curly hair formation in humans.

This study found that Magra sheep with high-luster wool exhibited significantly higher expression of keratin genes, suggesting that increased keratin protein levels may be crucial for wool luster.

This study analyzed skin specimens from Australian Merino ewes to estimate hair follicle properties across different strains, providing baseline data essential for future genetic studies on fleece structure, but reported no new conclusions.

In these studies, researchers found that Peruvian camelids reach mature skin follicle development early, with specific cuticular characteristics useful for distinguishing fleece types, while Bolivian llamas have a mature follicle apparatus present at birth.

This study found that melatonin treatment improved cashmere production for one cycle in cashmere goats, enhancing fiber quality and follicle activity, but had no effects in the subsequent cycle.

This study found that ectopic expression of FGF5s in transgenic Chinese Merino sheep increased wool length and greasy fleece weight compared to non-transgenic controls.

This study examined vicuña skin and hair follicle structures, finding a high density of secondary hairs in fleece areas compared to belly and legs, and identified various types of cutaneous glands potentially important for chemical communication.

This study found that CRISPR/Cas9-induced loss-of-function mutations in the FGF5 gene significantly increased wool length and yield in genetically modified Chinese Merino sheep compared to wild-type controls.

Animal hair fibers like wool and mohair are strong when dry, but vicuna fibers are very brittle.

This study found that variation in the ovine KRTAP27-1 gene may influence wool growth, with certain genotypes associated with higher mean staple length and greasy fleece weight in sheep.

This study found that specific genetic variations in the IRF2BP2 gene influence fleece structure in sheep, with one variant completely determining coat type and another significantly modifying fiber characteristics, providing valuable insights for improving fleece quality through selective breeding.

This study found that Super Merino sheep have a higher wool follicle density, finer fleece, and distinct gene expression compared to Small Tail Han sheep, which may inform future breeding and genetic interventions.

In this study, Australian cashmere goats receiving protein supplements maintained their weight and showed increased fleece growth, though cashmere growth was largely unaffected.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

This study identified dynamic changes in DNA methylation associated with different growth stages in Tan sheep, which may offer insights to retain their valuable curly fleece as they age.

This study found that infused mouse epidermal growth factor induced wool follicle involution through a quasi-physiological process similar to catagen and a separate pathological action, resulting in fleece 'break' or shedding.

Among Merino × Southdown cross sheep, this study found that certain variants of the KRT81 gene were associated with differences in fleece weight, but not with staple length or fibre diameter traits.

This study suggests that the KAP 7 gene may serve as a potential molecular marker for genetic selection to improve staple length and greasy fleece weight in Rambouillet sheep.

This study suggests that miR-144 influences hair follicle dynamics through its impact on Lhx2, which could lead to advancements in cashmere production, fleece quality, and treatments for hair growth disorders.

This study applied a machine learning-based genomic analysis to identify genetic markers associated with wool traits in Central Anatolian Merino sheep, successfully highlighting loci relevant to fiber diameter, staple length, and greasy fleece yield, which could inform breeding programs to enhance wool quality and yield.

This study identified a gene variant in the TRPV3 gene that may explain the suri alpaca phenotype, characterized by longer and less crimped fleece, suggesting this variant's involvement in the development of these hair characteristics compared to the huacaya phenotype.
