research Effects of short photoperiod on cashmere growth, hormone concentrations and hair follicle development-related gene expression in cashmere goats

January 2023 in “Journal of applied animal research”

This study found that short-day photoperiod treatment in Shanbei white cashmere goats enhanced cashmere growth, increased secondary follicle density, and altered hormone levels and gene expression related to hair follicle development.

research The Microanatomy, Cell Replication, and Keratin Gene Expression of Hair Follicles during a Photoperiod-lnduced Growth Cycle in Sheep

20 citations , January 1995 in “Cells tissues organs”

The researchers reported that exposure to long days after short-day treatment induced a synchronized, out-of-season wool growth cycle in New Zealand Wiltshire sheep, similar to cycles induced in other species.

research Effects of photoperiod change on serum hormone level, hair follicle growth and antioxidant status in skin tissue of cashmere goats

March 2025 in “Frontiers in Veterinary Science”

In this study, altering the photoperiod in goats increased hormone concentrations and improved hair follicle development and skin antioxidant capacity, suggesting that short photoperiods may create favorable conditions for cashmere growth.

research Effect of constant-release melatonin implants and prolonged exposure to a long day photoperiod on prolactin secretion and hair growth in mouflon (Ovis gmelini musimon)

51 citations , January 2004 in “Domestic animal endocrinology”

This study concluded that an endogenous circannual rhythm of prolactin secretion in mouflon influences their seasonal hair growth and moulting cycle, which varies under different photoperiodic and melatonin treatments.

research A Microarray-Based Analysis Reveals that a Short Photoperiod Promotes Hair Growth in the Arbas Cashmere Goat

40 citations , January 2016 in “PLoS ONE”

The study found that exposing Arbas Cashmere goats to a short photoperiod significantly increased cashmere production by extending the anagen phase of hair follicles, with gene expression changes identified as contributing factors.
