Genetic correlation estimation procedure

Genetic correlation estimation procedure

Estimation of genetic correlations among countries takes place in test-runs and only when new or modified data are submitted from a country, according to the following procedure (as per Interbull technical workshop of January 2004, Uppsala, Sweden):

Step 1: Estimation of correlations

Data for estimation of genetic correlations are de-regressed breeding values for all AI bulls that have daughters in at least 10 herds. For mastitis and calving traits an additional requirement is that bulls have at least 50 daughters.

Correlations are estimated using the software package developed at Holstein Association USA (Klei & Weigel, 1998). Correlations are estimated simultaneously for all countries, except for Holstein, where subsets of 7 countries are considered. Countries are grouped into triplets, and per analysis correlations are estimated for countries in two triplets and the USA as link provider. Genetic correlation estimates for all country pairs are obtained by considering all possible combinations of triplets.

For each analysis only records from common bulls and bulls belonging to ¾-sib families with evaluations in multiple countries are used. Pedigree information is traced back until 1970; parents of ancestors born before 1970 are treated as missing and assigned to phantom parent groups. Phantom parent groups are defined according to origin, birth year of the bull and path of selection. Small groups are merged, where the first priority is given to combining birth years, and next to combining countries of origin. Genetic groups are treated as random effects.

Starting correlations for the REML procedure are the previously used correlations, and iterations are stopped when the relative change for all λ = Gij/√(Ri*Rj) is less than 10-6, where Gij is the sire covariance between country i and j, and Ri and Rj the residual variance in country i and j, respectively, or when the maximum change in correlation is less than 10-6. Aitken acceleration is used to speed up convergence.

Due to the country subsetting for Holstein, multiple estimates are obtained for the genetic correlation between some country pairs. The correlation matrix used in the next step (post-processing) is a combination of matrix of the maximum and average correlation estimates, weighted such to obtain the matrix with the highest smallest eigenvalue.

Step 2:Post processing

The following information sources are considered:
1. the correlation estimate from step 1
2. the correlation used in the previous run.
3. own expectations
4. correlations from Holsteins (only for non-Holstein breeds)
Estimates are required to fall within certain windows. For milk production traits, separate windows are maintained depending on the climate and whether or not countries predominantly have grazing system. Two countries with a similar climate and production system (grazing vs. non-grazing) are expected to be more correlated with each other than two countries with different climate or production system. If estimates are higher than the maximum (or lower than the minimum) value they are set to the maximum (or minimum) value. In addition, estimates are regressed towards a mean correlation within groups, the regression depending on the number of common bulls. Trait specific parameters are given below.
For breeds other than Holstein, and for some traits (production and udder health), estimates are combined with genetic correlations for Holstein. The approach to follow is similar to the one for Red Dairy Cattle conformation.

The two values (i.e. results from the preceding steps and the previously used correlations) are combined into a weighted average to avoid large changes in correlations between consecutive test runs. If the national evaluations for two countries have not changed, then the genetic correlation between these two countries is not expected to change much. However, if one of the countries introduced changes in their national evaluations, the genetic correlation between two countries may change. An increase in number of common bulls is expected to yield a more precise estimate of the genetic correlation, and more weight is given to the current estimate. This is done by increasing the weight on the current estimate proportionally to the increase in number of common bulls.

	Current estimate	Previously used correlation
No changes	1	3
Minor change in at least one country (e.g., data edit, pedigree improvement)	1	1
Major change in at least one country (e.g., new model or parameters)	1	0

Finally, the updated co)variance matrix is bended, using the bending procedure described by Jorjani et al. (2003).
