Maternal Index Value at 50th Percentile by Breed (& CED from Balanced Bull Type)
For educational purposes only
Maternal Index value in the top 50% of the breed combined with a CED from the Balanced Bull type table, could be a simple, yet balanced approach that producers may consider when selecting bulls to produce replacement females for their breeding herd. This approach would place positive selection pressure on the Maternal Index value, while maintaining a disciplined level of CED in the breeding herd.
