Using Shepherd^®, identifying sires and dams can be completed more easily with less work or interruption of the animal’s natural environment. DNA analysis on a lamb narrows the animal’s pedigree by ruling out unrelated parents to identify the single, correct pedigree. Shepherd allows for multi-sire mating programs, eliminates manual breeding recordings and avoids data errors from unplanned matings or manual misrecordings. The test also provides information for breeding values and selection indices and can be used as a basis for Pfizer Animal Genetics’ sheep gene tests.
