Using the power of DNA, IGENITY helps you understand and manage the of potential for animals perform and and Using the power DNA, IGENITY helpstoyou understand transmit traits of economic importance. Theand comprehensive manage the potential for animals to perform transmit profile includes: traits of economic importance. The comprehensive profile includes:Composition Carcass The IGENITY profile scores for Yield Grade, Hot Carcass Weight, Ribeye Area, Carcass Composition
The profile scores for Yield using Grade, Hot Carcass Weight,that Ribeye Area, and IGENITY Backfat Thickness are calculated multiple DNA markers reflect and Backfat Thickness are calculated DNAprovide markers that reflect the animal’s genetic potential for theseusing traits. multiple These results a more the animal’s genetic potential these traits.
