Abstract: TUNEL method was adopted for vertical and longitudinal slip section of hair follicles, which were from lateral part of Liaoning Cashmere goats during a year in different months, two months as an internal. The results indicated that the dead cells which controlling growth of hair follicle were clustering disposed, the phenomenon of apoptosis on mechanocyte of hair papilla was hardly found. The correlation between cycling of growth and apoptosis of hair follicle was found. The cells of apoptosis decreased during anagen, the cells of apoptosis increased prominently. The trend of changing on apoptosis of hair follicle, from the two types of Liaoning Cashemere goats, was coincidence fundamentally, compared with seasonal type, only the quantity of apoptosis cells were fewer before anagen.

Key words: Liaoning Cashmere goats; hair follicle; apoptosis
