Rump Fat EBVs are estimates of genetic differences between animals in fat depth at the P8 rump site in a 400 kg carcase.
Rump Fat EBVs are calculated by measuring the fat depth at the P8 rump site (located at the intersection of the line from the high bone with a line from the inside of the pin bone) via either live animal ultrasound scanning or direct measurement of carcases in the abattoir, and/or genomic information. Rump Fat EBVs are expressed in millimetre units.
Higher Rump Fat EBVs indicate the animal is expected to produce progeny with greater fat depth in a 400 kg carcase.
