The effects of different types and levels of error in sire pedigree on variance, heritability, inbreeding coefficient, estimated breeding value, the accuracy of breeding value, and the genetic trend were evaluated. The proportion of interchanged sire (SIC) and progenies without sire (PWS) was varied in four steps from 25 to 100%. These eight pedigree files were compared to a pedigree file with complete pedigree information (CPI). The WOMBAT program fitting animal model was used to determine genetic parameters. The correlations among estimated breeding values (EBV) resulting from different pedigree files were estimated using SAS. Except for 25–50%PWS, all pedigree files with sire pedigree error overestimated the genetic variance (σ2a) and direct heritability (h2a) compared to a pedigree file with CPI. The error in sire pedigree affects EBV, the accuracy of EBV, and the rank of kids. The correlation estimate reduces with an increase of PWS and was similar for pedigree files with SIC. The magnitude of genetic reduction per year was lower for pedigree files with sire pedigree error compared to pedigree file with CPI. The mean inbreeding coefficient decreased (0.321–0.00%) with increasing the proportion of PWS. Pedigree files with sire pedigree error overestimated the direct heritability, total heritability, EBV, reduce the accuracy of EBV and genetic trend and underestimate the inbreeding level. However, the genetic parameter estimates derived from the pedigree file with SIC were nears to estimates from the pedigree file with CPI. Improving the recording system and awareness creation about its impact is imperative for a successful genetic improvement program and accurate genetic evaluation.
