AI Article Synopsis

  • The study analyzed the genetic diversity and population structure of the Simental breed using pedigree data from 77,553 animals.
  • The results showed a mean inbreeding coefficient of 1.49% and an average relatedness of 0.99%, suggesting low inbreeding levels.
  • Despite these low inbreeding rates, the findings highlighted the necessity for strategies to preserve genetic variability due to certain population parameters indicating potential risks.

Article Abstract

The purpose of this study was to estimate parameters related to the population structure and genetic diversity in the Simental breed based on the pedigree information of 77,553 animals. The individual coefficients of inbreeding and average relatedness, number of complete generations, coefficient of change of inbreeding, effective size, effective number of founders, number of ancestors and generation interval were calculated. Using the Simmental cattle information, the mean inbreeding and average relatedness coefficients were 1.49% and 0.99%, respectively. The effective number of founders and ancestors was 163 and 132, respectively, and the effective population size was 48.03. Despite the relatively small inbreeding coefficient, some of the estimated population parameters indicated the need to adopt measures to maintain the genetic variability of the population.
