Expected Progeny Differences (EPDs) are calculated using various data points to predict the genetic merit of an animal as a parent. Factors incorporated into these calculations include the individual’s own performance records (e.g., weight, growth rate, carcass traits), the performance records of its relatives (progeny, siblings, parents), and increasingly, genomic information derived from DNA testing. These sources of information are combined using statistical models to generate the EPD values.
The utilization of EPDs offers significant advantages for livestock breeders. They facilitate informed selection decisions, accelerating genetic improvement within a herd or breed. Incorporating multiple generations of performance data along with genomic insights enhances the accuracy and reliability of these predictions. This leads to more effective breeding strategies and ultimately, improved animal productivity and profitability.
