Have you ever wondered why bull proofs arent comparable across countries? They arent because each country has... - different cow populations - different animal identification and herdbook registration systems for recording parentage info - different milk recording systems (that may or may not record data related to calving ease, fertility, longevity, milking speed and milking temperament, disease events, etc) - different type classification systems - different trait definitions - different evaluation systems for calculating bull proofs and cow indexes - different scales of expression for genetic evaluations
