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

The study investigated the effect of a short photoperiod on hair growth in Arbas Cashmere goats, revealing that it extended the anagen phase of hair follicles, thereby increasing cashmere production. Gene expression analysis showed that the short photoperiod altered the expression of genes involved in hair follicle growth and skin appendage morphogenesis. These findings enhanced the understanding of hair follicle growth in Cashmere goats and suggested potential for developing artificial methods to improve cashmere production through light cycle control, which could benefit livestock breeding.
