Breed Composition Codes for Crossbred Dairy Cattle in the United StatesJohn B. Cole, Ph.D.
Crossbreds are animals whose genes are derived from more than one breed, such as a cow with a Holstein sire and a Jersey dam. A system for storing breed composition data for US dairy cattle has been developed and the necessary software implemented. This system is necessary to facilitate implementation of an across-breed genetic evaluation. Crossbred animals in the US dairy cattle population do not currently receive genetic evaluations. Two ways that crossbred animals may be handled in an evaluation are: they may be included in the breed-of-sire evaluation, or all animals may be combined into a single evaluation. For each crossbred cow (n=246,218) the database stores animal identification, breed of animal registry, breed fractions for 18 dairy breeds and an “unknown” category, a four-generation breed stack, a sire breed stack, and a heterosis value. Standard two-letter breed codes are used in the breed stacks. Breed fractions were calculated from pedigree information in the USDA database as far back as data were available.
