In this study, 108 individuals of Aba Tibetan pig from Pujiang county (Sichuan province) were selected to investigate the polymorphisms of the fourth intron of pituitary specific transcription factor 1 (POU1F1) gene. The results showed that four loci of single nucleotide polymorphisms (g.13952A>G, g.14192T>C, g.14384G>C, and g.14464T>A) were detected, constituting six haplotypes (H1~H6) and 11 haplotype combination (H1H1, H1H2, H1H4, H1H5, H1H6, H2H2, H2H6, H3H3, H3H4, H5H6, H6H6). Additionally, 14 growth traits were measured among pigs of 2-month- (100), 3-month- (86) and 4-month-old (82), respectively. However, no significant difference in these growth traits was observed between boars and sows except heart girth and abdominal girth in 4-month-oldThe correlation analysis between growth traits and haplotype showed that individuals with H1H1 haplotype performed the lowest growth rate, suggesting that more attention should be paid to these pigs in further miniaturization selection.
