Comprehensive analysis of differences in cashmere production performance in Liaoning cashmere goats by using metabolomics and transcriptomics.

ABSTRACT:

Introduction

The Liaoning cashmere goat is a precious dual-purpose breed in China. Although cashmere yield has improved through years of selective breeding, there remains potential for further enhancement. A subset of these goats exhibits a perennial long-wool (PT-LCG) trait, characterized by higher cashmere yield and an extended fiber growth cycle, whereas others display a seasonal long-wool (ST-LCG) pattern. The molecular mechanisms underlying these distinct traits are not yet fully understood.

Methods

Skin tissue samples were collected from six female PT-LCG and six ST-LCG goats during the catagen phase (November). Histological structure of secondary hair follicles (SHFs) was examined via H&E staining. Untargeted metabolomic profiling was performed using gas chromatograph
