摘要: Research on the identity of genes and their relationship with traits of economic importance in farm animals could assist in the selection of livestock. In this study, the polymorphisms of insulin-like growth factor 1 (IGF1) gene in 561 goats of ten breeds were detected by polymerase chain reaction (PCR)-single strand conformation polymorphism (SSCP) and their association with litter size and birth weight in three breeds were investigated. The effects of IGF1 polymorphisms on the breeding value for litter size and birth weight were examined using least square methods. Two deletions (CA) were detected in the microsatellite and two mutations (A1637G, T1640C) were found in 5´-flanking regulatory region. No significant association between the polymorphisms in 5´-flanking region of IGF1 and birth weight was found in the three breeds of goats. In Gulin Ma goats, two polymorphisms were found to affect litter size traits. In Chuandong White goats and Guizhou White goats, no significant difference (P<0.05) in litter size between goats carrying different genotypes was observed. Further evaluation and confirmation studies in more goat populations with larger sample sizes are necessary.
