American Guernsey Association Updates CPI/PTI Formula
The American Guernsey Association Board of Directors elected to update the CPI/PTI formula, effective for the December genetic evaluation, which will take place on December 4, 2018. Based on a recommendation from the Genetic Improvement Committee, the new formula balances the weight on Fat and Protein to 25% each. This is a change from the previous weighting of 20% Fat, 30% Protein.The remainder of the formula will be unchanged.
If you have any questions about the new formula or its implementation, contact Robin Alden at email@example.com.
