To analyze associations of polymorphisms of IGFBP-3 gene with cashmere traits in Inner Mongolia white Cashmere (IMWC) goat, significant statistical results are found in cashmere yields between individuals with H1H1 and H2H2 genotypes (P<0.05). The individuals with genotype H1H1 had higher cashmere yield than that of genotype H2H2 in three-year-old (P<0.05), but trend was reversed in five-year-old (P<0.05). Therefore, this study provided possible support for influence of IGFBP-3 gene on cashmere yield which might be at least partially dependent on age and circulating levels of PRL in Inner Mongolia white Cashmere goats.
