Cattle Dehorning Polled Genetic Progress

Progress in polled genetics for dairy cattle is accelerating, with polled versions of elite breeds becoming increasingly available.

Key Facts

The polled allele is dominant meaning one copy eliminates horn growth
Introgression of polled genetics into Holstein and Jersey breeds is advancing
Genomic selection tools accelerate polled allele spread while maintaining elite genetics
Some countries are now producing 30-40% polled Holstein offspring
Complete transition to polled herds would eliminate dehorning as a welfare procedure globally

Welfare Considerations

The genetic elimination of horns through polled breeding is one of the clearest examples of technology enabling permanent welfare improvement. Each generation with increasing polled frequency reduces the number of cattle requiring painful dehorning procedures.
