초록
This study was carried out to investigate the association of POU1F1 (POU domain, class 1, transcription factor 1, Pit1,renamed as POU1F1) gene with backfat thickness (mm), carcass weight (kg), pH, and color values (L*, a*, b*) in crossbredpigs (Landrace x Yorkshire x Duroc). Frequency of the AA genotype indel was at the highest level (66.67%). Frequencyof A allele (0.81) was higher than that of b allele (0.19). This population followed Hardy-Weinberg equilibrium. Carcassweights and a* values of the three genotypes were all significantly different (p < 0.05), respectively. However, backfatthickness, L*, b*, visual color, and pH of the three genotypes were not significantly different (p > 0.05). Visual color wasnegatively correlated with L* (r = .0.521) and b* (r = .0.390) values, L* value was correlated with b* (r = 0.419) value,and a* value was positively correlated with b* (r = 0.612) value. These results indicate that the POU1F1 gene affectedcarcass weight and meat redness.
Abstract
This study was carried out to investigate the association of POU1F1 (POU domain, class 1, transcription factor 1, Pit1,renamed as POU1F1) gene with backfat thickness (mm), carcass weight (kg), pH, and color values (L*, a*, b*) in crossbredpigs (Landrace x Yorkshire x Duroc). Frequency of the AA genotype indel was at the highest level (66.67%). Frequencyof A allele (0.81) was higher than that of b allele (0.19). This population followed Hardy-Weinberg equilibrium. Carcassweights and a* values of the three genotypes were all significantly different (p < 0.05), respectively. However, backfatthickness, L*, b*, visual color, and pH of the three genotypes were not significantly different (p > 0.05). Visual color wasnegatively correlated with L* (r = .0.521) and b* (r = .0.390) values, L* value was correlated with b* (r = 0.419) value,and a* value was positively correlated with b* (r = 0.612) value. These results indicate that the POU1F1 gene affectedcarcass weight and meat redness.
