There are several statistical packages that can be used to calculate traditional and genomic BLUP breeding values and the variance components of the traits that are needed for the breeding values. The most commonly used are ASREML (Gilmour et al., 2006), DMU (Madsen and Jensen, 2007) and VCE (Groeneveld et al, 2008). 

The design of a genetic improvement program has the purpose of structuring groups of (test) individuals in the population such that accurate breeding values for the traits under selection can be obtained and ensuring...

When no data are available, a value of 3.25 MJ/kg or breed values based upon the figures in Table 16.13 may be adopted. 

Complimentarity Improvement in performance of offspring from parents with different but complimentary breeding values. 

Heritability Measure of the relationship between phenotype and breeding value. 

Genomic estimated breeding values are expected to revolutionize dairy breeding programs. The calculation combines traditional parent average evaluation programs with the new genetic marker discoveries. 

Using estimated breeding values, a farmer can select for cows that calve easily or have calves with lower birth weight.
