title: [The effects of the GH, IGF-I and IGF-IBP3 gene on growth and development traits of Nanyang cattle in different growth period].
abstract: This study was conducted to identify polymorphisms of the Nangyang cattle's growth hormone (GH) and insulin-like growth factor-I (IGF-I) and insulin-like growth factor-I binding protein 3(IGF-IBP3) gene by the single nucleotide Polymorphisms and Polymerase chain reaction-based restriction fragment length polymorphism and to study association of polymorphisms identified in these genes with growth traits of the birth, 6 months, 12 months, 18 months, 24 months and 36 months. Results from the analysis showed a significant association of the BB genotype in the promoter of GH gene (GH-P5) with higher body length and body height during from 6 month to 18 month. From 24 month to 36 month, the IGF-IBP3 locus has a dominance modulation and control effect on backbody in Nanyang Cattle, and the BB genotype with higher Rump width than AA.
