Abstract: The cashmere growth and reproductive activity of cashmere goat are periodic, and they are regulated by many factors. Insulin-like growth factor (IGF), as a class of polypeptide growth factors, is involved in the process of cell mitosis, proliferation and differentiation, and anti-apoptosis. In addition, it also plays crucial roles in proliferation and differentiation of hair follicle epitheliums and dermal cells, follicular development, oocyte maturation, follicular atresia, and fetal growth and development. This article reviews the research progress on the IGF system and its regulative role in cashmere growth, follicular development and atresia, and fetal development in cashmere goat, in hoping to provide references for further investigation on regulation of economically important traits of cashmere goat by IGF.

Key words: cashmere goat, IGF system, cashmere growth, reproductive activity
