Numerical rankings of (livestock) parental genetics, in terms of an animal’s genetic impact on progeny’s four following commercial traits:<\/p>\n

    \n
  1. Number of progeny born alive<\/li>\n
  2. Weight of progeny at weaning age<\/li>\n
  3. Number of days required to reach slaughter weight, when fed adequately<\/li>\n
  4. Carcass lean meat versus fat percentages<\/li>\n<\/ol>\n

    EPDs allow a farmer to estimate differences in performance of future offspring (of a given parent) versus offspring produced by parents of average genetic value. For example, a boar (male pig) possessing an EPD of -4 for “number of days required to reach slaughter weight produces offspring that reach slaughter weight in four fewer days (offeeding time) than offspring that are sired by a boar possessing an EPD of 0.<\/p>\n
