ABSTRACT
The V54L missense mutation within the DECR1 gene, which encodes a mitochondrial 2,4- dienoyl-
CoA reductase, was investigated to determine whether this polymorphism is associated with growth
rate (daily gains), meat content and selection index in Polish Landrace boars kept under uniform
feeding and environmental conditions (one herd). The genotype of 334 boars was determined by PCRRFLP,
identifying 112, 162, and 60 boars bearing genotypes CC, CG and GG, respectively. Statistical
analysis was carried out by the General Linear Model (GLM) procedure, including fixed effects of
DECR1 genotype, sire, and birth season. Significant differences (P<0.01) between boars with CC and
GG genotypes were found. Boars with genotype CC showed the highest daily gains (860.7 g ± 46.3),
in comparison with boars bearing the GG genotype (841.7 g ± 53.6). The current findings support the
hypothesis that DECR1 V54L polymorphism is a promising marker of growth rate in pigs.
