The American Veterinary Medical Association (AVMA) has proposed using polled genetics as an alternative to dehorning. However, there are few polled dairy sires with high genetic merit for important economic indexes.
Genomic editing technology such as CRISPR/Cas9 offers tremendous potential for accelerating genetic progress, but a new ruling from the European Court of Justice (ECJ) appears likely to stifle research and development.
The use of transplants could add $100 per calf in potential profit over Holstein/beef crossbreds. The economic assessment is based on straight-bred beef calves’ better rate of gain and feed efficiency, better carcass weight and better grade at harvest.
