Abstract

This study examined trends in the genetic diversity in the Australian Angus cattle population through the calculation of inbreeding, effective population size, effective number of ancestors and effective number of founders over time. The effective population size ranged from 68 to 122 depending on the assumed generation interval. For animals born in 2018, 10 key ancestors explained ~42% of the genetic diversity within the population. Knowledge of overall genetic diversity will help manage the population to maintain long-term rates of genetic gain.
